RESUMO

This review is intended to provide an updated summary of, but not limited to, classification, etiopathogenesis, diagnosis, and treatment strategies for insomnia disorder. The severity of insomnia symptoms irrespective of co-existing primary medical condition/s in the studied patients classified insomnia as 'insomnia disorder' to prioritize the clinical attention on insomnia (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition). The frequency and duration of symptoms further divided insomnia into chronic, short-term, and other insomnia disorder (International Classification of Sleep Disorders, Third Edition). This disorder is a phenomenal state of hyperarousal developed and perpetuated by environmental, behavioral, cognitive, genetic, socioeconomic, preexisting medical factors. Overarching physiological, cortical, behavioral, and cognition changes in hyperarousal manifest insomnia disorder. It, sometimes, leads to the co-occurrence of other chronic medical condition/s. The contemporary diagnosis of insomnia disorder needs to consider modified diagnostic criteria, growing evidence on insomnia disorder symptoms, associated factors, co-existing medical condition/s (if any) to identify the subjective severity of insomnia disorder and design a treatment plan. The recommended treatment strategies include cognitive-behavioral therapy for insomnia (CBTI) and pharmacotherapy. However, CBTI lacks accessibility, qualified facilitators, and pharmacotherapy has limitations like side effects, physiological tolerance/dependence. The investigation of phytocompounds subdued these drawbacks of existing treatments as some compounds showed anti-insomniac potential. Furthermore, complementary alternative medicines (CAMs) like mindfulness-based practices, acupuncture, listening to music, Yogasanas, Pranayama, digital cognitive behavioral therapy for insomnia (dCBTI) during bedtime proved supportive in insomnia disorder treatment.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Cardiospermum halicacabum Linn. (C. halicacabum) is one of the well-known leafy green vegetables in India. It is an herbaceous climber from the Sapindaceae family which is found in almost every Continent and Oceania. In the traditional Indian medicine systems, this plant is used for the treatment of rheumatism, abdominal pain, orchitis, dropsy, lumbago, skin diseases, cough, nervous disorders, and hyperthermia. AIM OF THE REVIEW: This review presents the current information about ethnomedical uses and progress on geographical distribution, pharmacological activities, phytochemistry, micropropagation, and toxicity of C. halicacabum. Also, critically summarizes the relationship between the reported pharmacological activities and the traditional usages along with the future perspectives for research on this medicinal plant. MATERIALS AND METHODS: The data on C. halicacabum were collected using multiple internet sources such as Google Scholar, Science Direct, Taylor & Francis, PubMed, Web of Science, Springer Link, Wiley online, and plant databases. RESULTS: Chemical characterization using LC-MS/MS, HPLC, and NMR exposed the presence of chlorogenic acid, caffeic acid, coumaric acid, luteolin-7-o-glucuronide, apigenin-7-o-glucuronide, and chrysoeriol in different parts of C. halicacabum. Based on the outcomes of this review, the main bioactive compounds found in C. halicacabum include phenols, phenolic acids, flavonoids, flavonoid glycosides, and flavonoid glucuronides. Besides the above-mentioned constituents, palmitic acid, oleic acid, stearic acid, linolenic acid, eicosenoic acid, and arachidic acid are the compounds that constitute the fatty acid profile of C. halicacabum seeds. Specifically, Cardiospermin, a bioactive compound isolated from the root extract of C. halicacabum has been recognized for its anxiolytic activity. Moreover, C. halicacabum showed a broad spectrum of pharmacological activities including anti-inflammatory, anti-arthritic, anti-diabetic, anxiolytic activity, antiulcer, apoptotic activity, antibacterial, antiviral, anti-diarrheal, antioxidant, hepatoprotective, and nephroprotective properties. However, the bioactive compounds responsible for most of the above therapeutic properties have not been elucidated till now. CONCLUSION: Phytochemicals from C. halicacabum showed noticeable pharmacological effects against plethora of health disorders. Some of the traditional applications were supported by modern scientific studies, however, more pharmacological evaluations should be conducted to validate other traditional uses of C. halicacabum. Despite C. halicacabum's vast pharmacological activity, additional human clinical trials are needed to determine the potent and safe dosages for the treatment of various health abnormalities. Besides, bioassay-guided isolation of active constituents, pharmacokinetic evaluations and identification of their mode of action are recommended for future investigations on C. halicacabum to unveil its therapeutic drug leads. Overall, this review suggests that C. halicacabum could be a new source of functional foods.

RESUMO

Brassica juncea (BJ) is a familiar edible crop, which has been used as a dietary ingredient and to prepare anti-inflammatory/anti-arthritic formulations in Ayurveda. But, the scientific validation or confirmation of its therapeutic properties is very limited. This study was performed to determine the efficiency of BJ leaves for the treatment of Rheumatoid arthritis using in vivo and in silico systems. Standard in vitro procedures was followed to study the total phenolic, flavonoid contents and free radical scavenging ability of the extracts of BJ. The effective extract was screened and the presence of bioactive chemicals was studied using HPLC. Further, the possible therapeutic actions of the BJ active principles against the disease targets were studied using PPI networking and docking analysis. IL2RA, IL18 and VEGFA are found to be the potential RA target and the compounds detected from BJ extract have shown great binding efficiency towards the target from molecular docking study. The resulting complexes were then subject to 100 ns molecular dynamics simulation studies with the GROMACS package to analyze the stability of docked protein-ligand complexes and to assess the fluctuation and conformational changes during protein-ligand interactions. To confirm the anti-arthritic activity of BJ, the extract was tested in CFA-induced arthritic Wistar rats. The test groups administered with BJ extract showed retrieval of altered hematological parameters and substantial recovery from inflammation and degeneration of rat hind paw.Communicated by Ramaswamy H.

RESUMO

This investigation is to find a prolonged or delayed drug release system, exclusively for the treatment of hepatitis-B to reduce the side effects, which arise when conventional solid dose forms are administered. To pursue this goal, lamivudine-loaded Eudragit-coated pectin microspheres have been formulated employing water/oil (W/O) emulsion evaporation strategy. The formulation was optimised using a 34 factorial design. A drug to polymer ratio of 1:2, the surfactant of 1 ml, the volume of 50 ml of processing medium with a stirring speed of 2500 rpm were found to be the optimal parameters to obtain the lamivudine-loaded Eudragit-coated pectin microspheres formulation with a high drug entrapment efficiency of 89.44% ± 1.44%. The in vitro release kinetics of lamivudine was a suitable fit to the Higuchi model, indicating a diffusion-controlled release with anomalous transport. The obtained microspheres were then subjected to different characterisation studies, including scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and X-ray diffraction (XRD). The results of this study clearly indicate that Eudragit-coated pectin microspheres could be the promising controlled release carriers for colon-specific delivery of lamivudine in the presence of rat cecal content.

RESUMO

Chronic hyperglycemia and oxidative stress promote non-enzymatic glycation that leads to the production of advanced glycation end products (AGEs). AGEs casue significant damage to physiological proteins which result in several complications. The scenario also corresponds to the chronic consumption of a diet rich in AGEs. Despite understanding these mechanisms at the molecular level, the discovery of new drugs for these complications is under progress. Natural compounds might have great therapeutic potential for treating glycative consequences. In view of this, the study aimed to evaluate fruit extracts of Hylocereus polyrhizus towards determining its phenolics and flavonoid contents, as well as assessing it's in vitro antiglycative potential through the use of multistage glycation markers (early, intermediate and end stage products of ß-aggregation) in sugar-protein model. In vitro hypoglycemic activity of H. polyrhizus extracts was evaluated through α-amylase and α glucosidase inhibitory activities. In vitro antioxidant potential of the fruit extracts was also examined against different free radical types including DPPH and ABTS. Among the different in vitro assays performed, methanolic and acetone extracts of the fruit, with higher phenolics and flavonoid content, have exerted significant antiglycation and antioxidant activities than other extracts namely aqueous, ethanol, hydro-ethanol, hydro-methanol, and petroleum ether. Ultra-Performance Liquid Chromatography coupled with Electrospray Ionization Mass Spectrometry (UPLC-ESI-MS/MS) analysis was employed to identify active polyphenolics that may be responsible for the antiglycative potential of H. polyrhizus. The analysis revealed some high-profile compounds that have well documented for their therapeutic benefits. Additionally, In silico analysis also showed the possible connection between identified compounds and mechanisms of action. 4- Prenylresveratrol, Vicenin, and Luteolin had observed as effectively interact with target protein in molecular docking analysis. This suggests H. polyrhizus as a good source of anti-glycation and antioxidants that may have potential applications for the treatment and prevention of glycation associated diabetic and aging complications.

RESUMO

Rheumatoid Arthritis is a chronic, inflammatory, and systemic autoimmune disease, it affects elders worldwide. Herbal medicines have been used for the treatment of various ailments from ancient times. Betelvine (Piper betle L.) leaves have long been used in Asian countries as a medicine to relieve pain and some metabolic diseases. The present study of methanolic extract of phytochemical analysis confirms the presence of alkaloids, tannins, terpenoids, saponins, steroids, total flavonoids and total phenols. GC-MS analysis of MeOH extract of Piper betle (PBME) revealed the presence of 40 bioactive compounds. In vitro antioxidant and anti-inflammatory assays showed greater inhibitory effect. The anti-arthritic effects of PBME at 250 and 500 mg/kg concentration showed recovery from joint damage in in vivo rat model. Among the 40 GC-MS derived bioactives, 4-Allyl-1,2-Diacetoxybenzene exhibited the higher interactions with minimized binding energy to the RA targets of MMP 1 (-6.4 kcal/mol), TGF-ß (-6.9 kcal/mol), IL-1ß (-5.9 kcal/mol). Further, the effect of PBME extract against RA molecular disease targets (IL-1ß, MMP1 and TGF- ß) were studied using Real-time PCR. These results substantiate that P. betle leaves could be a source of therapeutics for the treatment of rheumatoid arthritis.

RESUMO

The Cissus quadrangularis (CQ) stem has interesting nutritional and pharmacological properties to promote the health of the skeletal system. It is a well-recognized plant in the conventional system of medicine in India for treating bone and joint-associated complications. This study focuses on identifying the active constituents from the stem and root extracts of CQ and validating its anti-osteoarthritic activity by the in vivo model. Notable levels of phenolics and flavonoids were found in the ethanol extracts of both CQ stem (CQSE) and root (CQRE), among other solvent fractions. UPLC-MS/MS analysis of these selective extracts resulted in different classes of active compounds from both positive and negative ionization modes. By analyzing their mass spectra and fragmentation pattern, 25 active compounds were identified. The CQSE and CQRE extracts, along with the standard drug (naproxen), were further tested in mono-sodium iodoacetate-induced experimental OA animals. The modulatory effects of the test extracts were assessed by haematology, synovial and cartilage marker profiling, radiology and histopathological analysis. The in vivo findings from the biochemical and physiological studies have led to the conclusion that the CQSE extract is a good choice for the management of OA. The results were substantially better than CQ root extract and naproxen drug-treated groups. Thus, CQS has bioactive constituents, which could facilitate recovery from joint tissue damage, cellular metabolism and associated risk factors attributable to dysfunctions in OA incidence and progression.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Momordica cymbalaria, a wild vegetable belongs to the Cucurbitaceae family, has long been used as a food and a remedy for diabetes mellitus in the Asian native medicinal system. AIM OF THE STUDY: This study aims to evaluate the efficacy of ethanolic extract of skin (EESK) and methanolic extract of seed (MESE) of M. cymbalaria (MC), for their hypoglycemic and hypolipidemic effects in alloxan induced diabetic rats. MATERIALS AND METHODS: The diabetes induced rats were given skin and seed extracts at doses 250 and 500 mg/kg b.w. p.o. for 28 days. Alloxan monohydrate (120 mg/kg) was used to induce diabetes mellitus. Daily food and water intake were assessed. Blood glucose levels and body weights were measured every 7 days throughout the experiment. Antioxidant assays, different biochemical and glycemic parameters were evaluated. Histopathological studies on pancreas, liver and kidney were also studied. RESULTS: Treatment of EESK and MESE showed dose significant decrease in fasting blood glucose level (FBG) in experimental diabetic animals with significant reduction in food and water intake and increase in body weight. Findings confirmed the hypoglycemic and hypolipidemic effects of EESK and MESE in the experimental groups. The impaired glucose tolerance and altered activities of the hepatic enzymes such as AST, ALT and ALP levels of diabetic rats were significantly improved by the administration of EESK and MESE. Oral treatment with MC extract for 28 days demonstrated significant protective effects on the lipid profile, biochemical parameters and antioxidant levels. Besides, biochemical findings were supported by histopathological investigations. CONCLUSION: These results suggest that the treatment with EESK and MESE of MC at a dose of 500 mg/kg b.w. have better protective effects against hyperglycemia, hyperlipidemia and oxidative stress generated during diabetes justifying the use of the plant in traditional systems of medicine.

RESUMO

Type 2 Diabetes Mellitus (T2DM) is very common metabolic disorder affecting people of all age groups. The change in life style and environmental factors are the considerable factors which are involved in the development of the disorder. The different parts of medicinal plants vary in their composition of bioactive compounds. There are reports on antidiabetic activity of C. auriculata L. flower and leaves. Traditionally bud of C. auriculata L. is used to treat diabetes rather than flower. This study aims to explore the antidiabetic efficiency of bud and flower and to identify the differential composition of phycompounds present in bud and flower parts of C. auriculata L. The compounds present in the bud and flower parts were identified using LC-ESI/MS analysis. Antidiabetic activity of C. auriculata L. bud and flower parts was studied in high fat diet (HFD) and streptozotocin (STZ) induced diabetic rats. During which parameters such as feed intake, water intake, and body weight were monitored. After 21 days of the study, blood parameters like insulin, glucose, lipid profile, hepatic function test, renal function test and oxidative stress markers were analysed. Real time PCR was done to monitor the expression of IRS2 and GRIA2 genes. The LC-ESI/MS analysis showed the presence of various phenolics and flavonoid compounds specific to bud and flower parts. The antidiabetic activity results showed that the animal treated with C. auriculata L. bud ethanol extract (CABE500) could better reverse and control the progression of the disease compared to the flower ethanol extract. The gene expression studies revealed that regulation of IRS2 gene occurred in bud but not in flower extract treated animal livers and no differential expression of GRIA2 gene in all the experimental groups. C. auriculata L. bud extract can potentially better control the diabetes compared to the flower extract.
