RESUMO

The term "inflammatory bowel disease," which includes Crohn's disease (CD) and ulcerative colitis (UC), refers to a chronic inflammatory condition of the digestive system. There are many different treatment options, such as corticosteroids, biologics, 5-aminosalicylate, and immune-suppressants, but none of them can maintain the disease remission for a longer period, which is the ultimate goal of treatment. Furthermore, they have numerous serious side effects like nephrotoxicity, infertility, congestive heart failure, myopathy, etc. So, in order to treat these conditions, researchers are concentrating more on natural medicine that is less expensive and has fewer side effects. The current analysis includes a list of plants showing promising activity against IBD. These include Cannabis sativa, Aloe vera, Boswellia serrata, Withania somnifera, Curcuma longa, Triticum aestivum, and many others. These plants need to be further investigated in terms of preclinical and clinical studies to obtain the safety and efficacy data necessary for their commercialisation. Global regulatory norms will facilitate simple commercialisation. Also, more investigation is required to pinpoint the precise mechanism of action to confirm clinical success.

RESUMO

INTRODUCTION: Ziziphus mauritiana, sometimes called Indian jujube or Ber, belongs to the Rhamnaceae group of plants. The aqueous and ethanolic Ziziphus mauritiana formulations were shown to have analgesic, antipyretic, potent analgesic, anti-inflammatory, and anti-emetic properties. AIM & OBJECTIVES: The aim of this study is to investigate the sedative and anticonvulsant activities of Ziziphus mauritiana extract by governing 200 and 400 mg/kg body weight orally. MATERIAL AND METHODS: The leaves are extracted with ethanol and lukewarm water with a soxhlet apparatus for 72 hours. After that acute extract toxicity study was performed and then locomotor activity, pentobarbital induced sleeping time and anticonvulsant activity were performed with the extract. RESULTS: Oral administration of extract at dosages of 200 & 400 mg/kg was employed after an immediate toxicity test. At a dosage of 400 mg/kg, the number of locomotions was reduced significantly lengthened the period of time spent sleeping and there was showed a dosage-dependent reduction in all phases of an epileptic episode. CONCLUSION: In this study, the extract reduced locomotor activity, however, it had a superior profile for an antiepileptic action than phenytoin since it decreased locomotor activity to a lesser level. The considerable increase in pentobarbitone sleep hours with the extracts at a higher dose supported the sedative action of Z. mauritiana.

RESUMO

BACKGROUND: The degenerative tendency of diabetes leads to micro- and macrovascular complications due to abnormal levels of biochemicals, particularly in patients with poor diabetic control. Diabetes is supposed to be treated by reducing blood glucose levels, scavenging free radicals, and maintaining other relevant parameters close to normal ranges. In preclinical studies, numerous in vivo trials on animals as well as in vitro tests are used to assess the antidiabetic and antioxidant effects of the test substances. Since a substance that performs poorly in vitro won't perform better in vivo, the outcomes of in vitro studies can be utilized as a direct indicator of in vivo activities. OBJECTIVE: The objective of the present study is to provide research scholars with a comprehensive overview of laboratory methods and procedures for a few selected diabetic biomarkers and related parameters. METHOD: The search was conducted on scientific database portals such as ScienceDirect, PubMed, Google Scholar, BASE, DOAJ, etc. Conclusion: The development of new biomarkers is greatly facilitated by modern technology such as cell culture research, lipidomics study, microRNA biomarkers, machine learning techniques, and improved electron microscopies. These biomarkers do, however, have some usage restrictions. There is a critical need to find more accurate and sensitive biomarkers. With a few modifications, these biomarkers can be used with or even replace conventional markers of diabetes.

RESUMO

Cardiotoxicity is a well-known adverse effect of cancer-related therapy that has a significant influence on patient outcomes and quality of life. The use of antineoplastic drugs to treat colorectal cancers (CRCs) is associated with a number of undesirable side effects including cardiac complications. For both sexes, CRC ranks second and accounts for four out of every ten cancer deaths. According to the reports, almost 39% of patients with colorectal cancer who underwent first-line chemotherapy suffered cardiovascular impairment. Although 5-fluorouracil is still the backbone of chemotherapy regimen for colorectal, gastric, and breast cancers, cardiotoxicity caused by 5-fluorouracil might affect anywhere from 1.5% to 18% of patients. The precise mechanisms underlying cardiotoxicity associated with CRC treatment are complex and may involve the modulation of various signaling pathways crucial for maintaining cardiac health including TKI ErbB2 or NRG-1, VEGF, PDGF, BRAF/Ras/Raf/MEK/ERK, and the PI3/ERK/AMPK/mTOR pathway, resulting in oxidative stress, mitochondrial dysfunction, inflammation, and apoptosis, ultimately damaging cardiac tissue. Thus, the identification and management of cardiotoxicity associated with CRC drug therapy while minimizing the negative impact have become increasingly important. The purpose of this review is to catalog the potential cardiotoxicities caused by anticancer drugs and targeted therapy used to treat colorectal cancer as well as strategies focused on early diagnosing, prevention, and treatment of cardiotoxicity associated with anticancer drugs used in CRC therapy.

RESUMO

OBJECTIVES: Elaeocarpus ganitrus, a member of the Eleocarpaceae family, is valued in Hinduism and Ayurveda, and is frequently used as a remedy for a variety of illnesses. The plant is reputed to treat a number of stomach issues. The purpose of the study was to produce high-quality scientific data regarding gastroprotective behavior, docking experiments with cholinergic receptors, and HPTLC (with lupeol and ursolic acid). To develop the mechanism of herbal extracts, in vitro anticholinergic and antihistaminic activities were evaluated. Different leaf extracts were treated with various reagents to determine the presence of various metabolites. An examination of the histopathology was conducted to determine the full impact of the extract. METHODS: Methanolic extract was chosen for HPTLC investigations after extraction with various solvents. A mobile phase of toluene, ethylacetate, and formic acid (8:2:0.1) was chosen. Molecular docking was utilized to examine how ursolic acid and lupeol are bound to cholinergic receptors (M3). Different extracts (aqueous and ethanolic) were tested for their ability to provide gastroprotection in Wistar rats at different doses (200 and 400 mg/kg). RESULTS: Phytochemical analysis of different extracts showed the presence of different primary and secondary metabolites. HPTLC data showed the presence of both standards. Docking studies exhibited very good interactions with the M3 receptor. Pharmacological studies revealed that extract-treated groups significantly reduced the ulcer index in all of the models mentioned above. The histopathological analysis clearly supports the biochemical studies, which were conducted utilizing various doses and found to be effective in a dose-dependent manner. The in vitro analysis proved that the abovementioned extracts may act as antagonists of acetylcholine and histamine. CONCLUSION: The data obtained would be valuable for the production of the monograph of the plant and conducting concept-related clinical studies in the future. More investigation is required since the gathered scientific data may lead to new research opportunities.

RESUMO

In underdeveloped nations, colorectal carcinogenesis (CRC) is a significant health issue. It is the third most common outcome of cancer death. Despite a variety of therapy options, new medications are needed to lessen the severity of this condition. In the colon, adenomatous polyps are the most common cause of CRC, occurring in 45 percent of cases, particularly in patients over 60 years old. Inflammatory polyps are acquiring popularity in CRC, as well as inflammation appears to exert a function in the disease, according to mounting research. The azoxymethane, dimethyl hydrazine, APCmin/+ mouse model, and a combination of sulfated polysaccharides composed of dextran and sulfated and dimethylhydrazine are among the experimental models used to study CRC in animals. Numerous signal transduction pathways are engaged as CRC progresses. The p53, TGF-ß, Delta-Notch, Salvador-Warts-Hippo (SWH), and Kelch-like ECH associated protein 1 pathways are among the key signal transduction pathways. To decide cell destiny, several signalling pathways work in tandem with the death of cell modalities, such as autophagy, necroptosis, and apoptosis. In our lab, we have spent a lot of time looking into the cell signalling and mechanisms of cell death in CRC. The pathogenesis of CRC, as well as the associated cell death and cell signalling pathways, are summarised in this study.

RESUMO

INTRODUCTION: Diabetes mellitus (DM) and steroid medication, coincided with coronavirus disease 2019 (COVID-19), results in a weakened immune system, allowing some commonly found pathogens to become more harmful. Mucormycosis (black fungus) is a type of opportunistic infection caused by fungi belonging to the Mucorales family. DM is the most prominent risk factor for mucormycosis. Excessive blood sugar and decreased insulin levels lead to diabetic ketoacidosis (DKA), a devastating complication of DM that can be fatal if left untreated. METHODS: Diabetic ketoacidosis is more common in type 1 diabetic patients, although it can also be fall in type 2 diabetic patients. DKA occurs when the body lacks enough insulin to allow blood sugar to enter the cells and is used for energy. Instead, the liver breaks down fat for fuel-producing chemicals known as ketones. RESULTS: When too many ketones are created too quickly, they can reach dangerously high levels in the body. Mucormycosis is a rare but serious infectious disease that requires medication or surgical removal. CONCLUSION: The confluence of diabetes and COVID-19 makes managing mucormycosis a serious and dead issue. Although the effectiveness of prophylactic antifungal therapy has yet to be demonstrated, hyperglycemia control appears to be the most important step in managing mucormycosis in DKA patients.

RESUMO

Ovarian cancer is characterized by the establishment of tolerance, the recurrence of disease, as well as a poor prognosis. Gene signatures in ovarian cancer cells enable cancer medicine research, therapy, prevention, & management problematic. Notwithstanding advances in tumor puncture surgery, novel combinations regimens, and abdominal radiation, which can provide outstanding reaction times, the bulk of gynecological tumor patients suffer from side effects & relapse. As a consequence, more therapy alternatives for individuals with ovarian cancer must always be studied to minimize side effects and improve progression-free and total response rates. The development of cancer medications is presently undergoing a renaissance in the quest for descriptive and prognostic ovarian cancer biomarkers. Nevertheless, abnormalities in the BRCA2 or BRCA1 genes, a variety of hereditary predispositions, unexplained onset and progression, molecular tumor diversity, and illness staging can all compromise the responsiveness and accuracy of such indicators. As a result, current ovarian cancer treatments must be supplemented with broad-spectrum & customized targeted therapeutic approaches. The objective of this review is to highlight recent contributions to the knowledge of the interrelations between selected ovarian tumor markers, various perception signs, and biochemical and molecular signaling processes, as well as one's interpretation of much more targeted and effective treatment interventions.

RESUMO

BACKGROUND: Coumarin is an oxygen-containing compound in medicinal chemistry. Coumarin plays an important role in both natural systems like plants and synthetic medicinal applications as drug molecules. Many structurally different coumarin compounds have been found to possess a wide range of similarities with the vital molecular targets in terms of their pharmacological action and small modifications in their structures, resulting in significant changes in their biological activities. OBJECTIVE: This review provides detailed information regarding the studies focused on the recent advances in various pharmacological aspects of coumarins. METHODS: Various oxygen-containing heterocyclic compounds represent remarkable biological significance. The fused aromatic oxygen-heterocyclic nucleus can change its electron density, thus altering the chemical, physical and biological properties, respectively, due to its multiple binding modes with the receptors, which play a crucial role in the pharmacological screening of drugs. Several heterocyclic compounds have been synthesized which have their nuclei derived from various plants and animals. In coumarins, the benzene ring is fused with a pyrone nucleus which provides stability to the nucleus. Coumarins have shown a wide range of pharmacological activities, such as anti-tumor, anticoagulant, anti-inflammatory, anti-oxidant, antiviral, antimalarial, anti-HIV, antimicrobial, etc. Results: Reactive oxygen species, like superoxide anion, hydroxyl radical, and hydrogen peroxide, are a type of unstable molecule containing oxygen, which reacts with other molecules in the cell during metabolism; however, when the number of reactive oxygen species increases, it may lead to cytotoxicity, thereby damaging the biological macromolecules. Hydroxyl Radical (OH) is a strong oxidizing agent and it is responsible for the cytotoxicity caused by oxygen in different plants, animals, and other microbes. Coumarin is the oldest and effective compound having antimicrobial, anti-inflammatory, antioxidant, antidepressant, analgesic, anticonvulsant activities, etc. Naturally existing coumarin compounds act against SARS-CoV-2 by preventing viral replication and targeting the active site against the Mpro target protein. CONCLUSION: This review highlights the different biological activities of coumarin derivatives. In this review, we provide an updated summary of the researches which are related to recent advances in biological activities of coumarins analogs and their most recent activities against COVID -19. Natural compounds act as a rich resource for novel drug development against various SARS-CoV-2 viral strains and viruses, like herpes simplex virus, influenza virus, human immunodeficiency virus, hepatitis B and C viruses, middle east respiratory syndrome, and severe acute respiratory syndrome.

RESUMO

The aim of the present study was to review the streptozotocin-nicotinamide (STZ-NA) diabetes model. Type 2 diabetes is more prevalent (90-95%) in adults than type 1. Experimentally- induced diabetes models may be established by chemicals, viral agents, insulin antibodies, surgery, etc. The most advisable and prompt method to induce diabetes is using chemicals, and STZ and alloxan are widely used chemicals. STZ has proven to be a better diabetogenic agent than alloxan because alloxan has many drawbacks, as it induces only type 1 diabetes, has a high mortality rate in rats, and causes ketosis in animals. Moreover, it has lesser selectivity towards ß-cells, and the diabetes-induced is reversible. STZ can be used to induce both type 1 and type 2 diabetes. It is noted that the genotoxic behavior of STZ in animals is accomplished through a reduction of nicotinamide adenine dinucleotide (NAD+) in pancreatic ß-cells via the GLUT2 (Glucose transporter 2), which can cause cellular damage by DNA (Deoxyribonucleic acid) strand breaks that lead to cell death. NA is a biochemical precursor of NAD+, and it is a poly-ADP-ribose-polymerase-1 (PARP- 1) inhibitor. NAD+ is an important redox reaction co-enzyme for the production of adenosine triphosphate (ATP) and many other metabolic pathways. Extreme DNA damage contributes to the over-activation of PARP-1, loss of cellular resources, and necrotic cells death. Some studies have expressed that NA can protect pancreatic ß-cells against the severe cytotoxicity of STZ. The review concluded that the STZ-NA model is dependent on the competency of NA to attain partial protection against the ß-cytotoxic essence of STZ to induce type-2 diabetes.

RESUMO

BACKGROUND: Diabetes mellitus (DM) is among the most frequently reported comorbidities in patients tainted with the pandemic coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). With a high pervasiveness of diabetes mellitus, there is an urgency to understand the special aspects of COVID-19 in hyperglycemic patients. Diabetic patients are at higher risk than the general population of viral or bacterial infections, thus require special attention since diabetes is linked with severe, critical, and lethal modes of COVID-19. OBJECTIVE: The objective of this study was to focus on epidemiology, pathophysiology, mechanism, and management of DM with COVID-19. METHODS: The search was carried out on databases portals such as Pubmed, EMBASE, Google Scholar, and CINAHL with the keywords, i.e., COVID-19, coronavirus, SARS-CoV-2, diabetes, covid-19, etc. Result: DM and COVID-19 disease conditions can impact each other in terms of clinical progression and outcome. Available laboratory/clinical observations suggest that hyperglycemia-induced immune dysfunction, inflated lactate grades, and cytokines storm may play critical roles in the seriousness of COVID-19 in patients with diabetes; however, the exact mechanisms linking diabetes and COVID-19 remain to be further clarified. CONCLUSION: Standards to constrain the disease spread at the individual and community level are the key to extenuate the speedily rising pandemic, while definitive treatment, like plasma therapy, chemoprophylaxis, or vaccine for COVID-19, has yet to be discovered.

RESUMO

Numerous novel medicinal agents isolated from plant sources were used as indigenous remedies for the management and treatment of various types of cancer diseases. Naringenin is a naturally occurring flavanone glycoside, and aglycone (genin) moiety of naringin, predominantly found in citrus and grapefruits, has emerged as a potential therapeutic agent for the management of a variety of diseases. A number of scientific papers have been published on naringenin describing its detailed studies and its therapeutic application in different diseases. The current study highlights a comprehensive study on naringenin concerning its biosynthesis, molecular targets/pathways involved in carcinogenesis, mechanism of actions (MOAs), and structure-activity relationships (SARs), and patents granted have been highlighted. Naringenin and its derivatives have great anti-cancer activity due to their inhibitory potential against diverse targets, namely ABCG2/P-gp/BCRP, 5a-reductase, 17- bhydroxysteroid dehydrogenase, aromatase, proteasome, HDAC/Situin-1, VEGF, VEGFR-2 kinase, MMP-2/9, JAK/STAT signaling pathways, CDC25B, tubulin, topoisomerase-II, cathepsin-K, Wnt, NF-kB, B-Raf and mTOR, etc. With the in-depth knowledge of molecular targets, structural intuition, and SARs, the current study may be beneficial to design more potent, safe, effective, and economic anti-cancer naringenin. This has been concluded that naringenin is a promising natural product for the management and therapy of cancer. Further evolution for pharmacological importance, clinical research, and trials are required to manifest its therapeutic action on metabolic syndrome in the human community.

RESUMO

Abstract The present study was designed to evaluate the beneficial synergistic effects of S-allyl Cysteine (SAC) and Taurine (TAU) on hyperglycemia, lipid profile and renal damage markers in type 2 diabetes mellitus (T2DM) in rats. Experimental T2DM was developed by administering an intraperitoneal single dose of nicotinamide (NA; 230 mg/kg) and streptozotocin (STZ; 65 mg/ kg) in adult rats. Control and diabetic rats were treated with SAC (150 mg/kg); TAU (200 mg/ kg) or SAC and TAU (75+100 mg/kg) combination for four weeks. Measurements of traditional markers of kidney toxicity in serum, such as blood urea nitrogen (BUN), serum creatinine (Scr), and alkaline phosphatase (ALP), together with serum cholesterol/triglyceride such as serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and very low-density lipoprotein cholesterol (VLDL-C) may yield a snapshot of renal damage and lipid profile in NA/STZ-treated rats. The variation in levels of fasting blood glucose, glycosylated hemoglobin, insulin and lipid profile was significantly augmented in SAC/TAU treatment group. The diabetic group showed elevated renal injury markers in serum, which were decreased significantly by SAC/TAU treatment. Thus the results of the experiment clearly indicate the potential of the SAC/TAU combination in improving diabetic complications.

RESUMO

Ziziphus mauritiana (Rhamnaceae), commonly known as Indian jujube, is a pharmacologically diverse medicinal plant. A plethora of active phytochemical constituents of this plant has been revealed so far, namely, berberine, quercetin, kaempferol, sitosterol, stigmasterol, lanosterol, diosgenin, and so forth. Several studies demonstrated the exploration of pharmacological potential of various parts such as fruits, leaves, and stems of the plant as antioxidant, cytotoxic, antimicrobial, anti-diarrhoeal, antidepressant, immunomodulator, and hepatoprotective. This review gives a unique summary including phytochemistry, nutritional value, and significant pharmacological importance of Z. mauritiana. The literature search was carried out via search engine PubMed, Science Direct, and so on. The data were heterogeneous in terms of leaves, stem, roots, and fruits which were used for different experimental findings, which made the comparison a lengthy task. Study findings suggested that the extracts from this plant may possess numerous types of pharmacological activities. As the search for novel drugs from botanical sources continues, there is need for future investigations to isolate and characterize pharmacologically active agents that confer medicinal properties on Z. mauritiana, as well as to elucidate the structures of these agents by which they exert their healing properties and to scientifically validate the existing traditional practices concerning its health benefits.

RESUMO

BACKGROUND: Juniperus communis Linn. is an important plant in India traditional system of medicine which is widely used by different tribes in many countries. OBJECTIVE: In the present study, the antioxidant, cytotoxic and hepatoprotective activities of Juniperus communis leaves were investigated against various models. MATERIALS AND METHODS: ethanolic extract (70% v/v) of J. communis leaves was successively extracted using hexane and ethyl acetate to prepare various fractions. Total phenol content was resolute by the Folin-Ciocalteau's process. The antioxidant properties of the different fractions/extract of leaves of J. communis were examined by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and Fe2+ chelating ability. Cytotoxic activity was examined by cell viability assay on HepG2 cells. Hepatoprotective activity of ethyl acetate fraction (EAF) evaluated against PCM-Paracetamol-induced hepatic damage in Wistar albino rats. RESULTS: Total phenol content was found maximum 315.33 mg/GAE/g in EAF. Significant scavenging activity were found for EAF (IC50 = 177 µg/ml) as compared to standard BHT (IC50 = 138 µg/ml), while EAF showed good Fe2+ chelating ability having an IC50 value of 261 mg/ML compared to standard ethylenediaminetetraacetic acid (7.7 mg/mL). It was found that EAF treated group shows remarkable decrease in serum Aspartate aminotransferase, serum Alanine aminotransferase, total bilirubin, direct bilirubin, and alkaline phosphatase level in treatment group as compared to the hepatotoxic group. CONCLUSION: EAF of J. communis leaves is found to be potent antioxidant and hepatoprotective without any cytotoxicity and it can also be included in nutraceuticals with notable benefits for mankind or animal health. SUMMARY: Phenol-rich fraction (PRF) and other fractions/extract of Juniperus communis leaves were screened for antioxidant, cytotoxic, and hepatoprotective activity.Significant antioxidant and hepatoprotective activity without any cytotoxicity were found while treating with ethyl acetate fraction (EAF).
