RESUMO

Parkinson's disease (PD) is a neurodegenerative brain disease (NBD) developed due to dopaminergic neuron loss in the substantia nigra (SN). Vitamin D (VD), VD receptor (VDR), and VD metabolites are highly expressed in the human brain and play a critical role in maintaining different brain functions. VDRs are highly expressed in the SN that regulates the activity of dopaminergic neurons and synaptic plasticity. VD exerts protective and therapeutic effects against the development of PD by modulating dopaminergic neurons of SN. VD reduces oxidative stress and neuroinflammation in PD because of its anti-inflammatory and antioxidant activities. Different studies revealed the protective effect of VD in the management of PD. However, the potential therapeutic effect of VD in well-established PD remains controversial. Therefore, this review aims to elucidate VD's preventive and therapeutic roles in PD. In conclusion, VD deficiency is associated with increased PD risk, but VD supplementation in well-established PD plays little role.

RESUMO

Coronavirus disease 2019 (Covid-19) is a global diastrophic disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Covid-19 leads to inflammatory, immunological, and oxidative changes, by which SARS-CoV-2 leads to endothelial dysfunction (ED), acute lung injury (ALI), acute respiratory distress syndrome (ARDS), and multi-organ failure (MOF). Despite evidence illustrating that some drugs and vaccines effectively manage and prevent Covid-19, complementary herbal medicines are urgently needed to control this pandemic disease. One of the most used herbal medicines is berberine (BBR), which has anti-inflammatory, antioxidant, antiviral, and immune-regulatory effects; thus, BBR may be a prospective candidate against SARS-CoV-2 infection. This review found that BBR has anti-SARS-CoV-2 effects with mitigation of associated inflammatory changes. BBR also reduces the risk of ALI/ARDS in Covid-19 patients by inhibiting the release of pro-inflammatory cytokines and inflammatory signaling pathways. In conclusion, BBR has potent anti-inflammatory, antioxidant, and antiviral effects. Therefore, it can be utilized as a possible anti-SARS-CoV-2 agent. BBR inhibits the proliferation of SARS-CoV-2 and attenuates the associated inflammatory disorders linked by the activation of inflammatory signaling pathways. Indeed, BBR can alleviate ALI/ARDS in patients with severe Covid-19. In this sense, clinical trials and prospective studies are suggested to illustrate the potential role of BBR in treating Covid-19.

RESUMO

BACKGROUND: Recently, the coronavirus (COVID-19) pandemic is a chief public health disaster caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). There are no established effective preventive or therapeutic anti-COVID-19 drugs available except for some recently approved vaccines. Still, countless recent studies recommend various alternative and complementary approaches against COVID-19, which are medicinal herbs employed as traditional remedies to enhance immunity to struggle with viral infections. In addition, physicians worldwide are highly interested in vitamin and mineral supplements to help them combat COVID-19 either through protection or treatment. Dietary supplements specifically vitamin D, vitamin C, and zinc provide good prophylactic and therapeutic support to the presently available treatment regimens. In the present work, we have focused on plant-based remedies with promising anti-COVID-19 activities. AIM: To enable investigators and researchers to identify potential herbal compounds with anti-COVID activity to be used as promising therapies to combat this pandemic. MAIN BODY: This review highlights the recently published studies concerning natural traditional herbs, herbal bioactive metabolites, dietary supplements, and functional foods that could help prevent and/or treat COVID-19. Herein, we explored medicinal herbs as potential inhibitors of SARS-CoV-2 and discussed how these studies help form larger discussions of diet and disease. Moreover, by investigating the herbal bioactive components, we have outlined several medicinal herbs that can fight against COVID-19 by hindering SARS-CoV-2 replication and entry to its host cells, deterring the cytokine storm, and several other means. Finally, we have summarized various herbal products, functional foods, and dietary supplements with potent bioactive compounds which can inhibit and/or prevent COVID-19 disease progression. CONCLUSIONS: Based on the studies reviewed in this work, it was concluded with no doubt that phytochemical components present in various herbs could have a starring role in the deterrence and cure of coronavirus contagion.

RESUMO

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection is linked with inflammatory disorders and the development of oxidative stress in extreme cases. Therefore, anti-inflammatory and antioxidant drugs may alleviate these complications. Ginkgo biloba L. folium extract (EGb) is a herbal medicine containing various active constituents. This review aims to provide a critical discussion on the potential role of EGb in the management of coronavirus disease 2019 (COVID-19). The antiviral effect of EGb is mediated by different mechanisms, including blocking SARS-CoV-2 3-chymotrypsin-like protease that provides trans-variant effectiveness. Moreover, EGb impedes the development of pulmonary inflammatory disorders through the diminution of neutrophil elastase activity, the release of proinflammatory cytokines, platelet aggregation, and thrombosis. Thus, EGb can attenuate the acute lung injury and acute respiratory distress syndrome in COVID-19. In conclusion, EGb offers the potential of being used as adjuvant antiviral and symptomatic therapy. Nanosystems enabling targeted delivery, personalization, and booster of effects provide the opportunity for the use of EGb in modern phytotherapy.

RESUMO

Methotrexate (MTX), an antineoplastic and immunosuppressive drug, widely used in the treatment of different types of cancers and the management of chronic inflammatory diseases. However, its use is associated with hepatotoxicity. Vitamin C (VC) and curcumin (CUR) exhibit anti-inflammatory and antioxidant effects. Thus, we aimed to investigate the potential hepatoprotective effects of VC and CUR pretreatment alone and in combination against MTX-induced hepatotoxicity. Albino mice were randomly divided into 7 groups: the control group, which received only normal saline; MTX group; VC group, pretreated with VC (100 or 200 mg/kg/day orally) for 10 days; CUR group, pretreated with CUR (10 or 20 mg/kg/day orally); and combination group, which received VC (100 mg/kg) and CUR (10 mg/kg). MTX was administered (20 mg/kg, intraperitoneally) to all the groups on the tenth day to induce hepatotoxicity. Forty eight hours after MTX administration, the mice were anesthetized. Blood samples were collected, the liver was removed for biochemical analysis, and a part of the tissue was preserved in formalin for histopathological analysis. The results indicated that pretreatment with a combination of VC and CUR induced a more significant decrease in the serum levels of alanine transaminase, aspartate transaminase, alkaline phosphatase, and lactic dehydrogenase and a significant increase in the tissue level of superoxide dismutase and glutathione; furthermore, it induced a significant decrease in malondialdehyde levels and improvement in histopathological changes in the liver tissues, confirming the potential hepatoprotective effects of the combination therapy on MTX-induced liver injury. To conclude, MTX-induced hepatotoxicity is mediated by induction of oxidative stress as evident by increased lipid peroxidation and reduction of antioxidant enzyme activity. Pretreatment with VC, CUR or their combination reduces the MTX-induced hepatotoxicity by antioxidant and anti-inflammatory effects. However, the combined effect of VC and CUR provided a synergistic hepatoprotective effect that surpasses pretreatment with CUR alone but seems to be similar to that of VC 200 mg/kg/day. Therefore, VC and CUR combination or a large dose of VC could be effective against MTX-induced hepatotoxicity. In this regard, further studies are warranted to confirm the combined hepatoprotective effect of VC and CUR against MTX-induced hepatotoxicity.

RESUMO

Drug-induced liver injury (DILI) is the main cause of liver damage mediated by the excretion of toxic active drug metabolites. Omega-3 fatty acids and vitamin C have potent antioxidant, anti-inflammatory, and antiapoptotic effects that could offer protection against oxidative stress and liver damage. This study evaluated the hepatoprotective effect of omega-3 and vitamin C alone as well as in a combined form in methotrexate- (MTX-) induced acute liver injury in mice. Male ICR mice of seven groups (7 mice per group) were used. Groups 1 (control group) and 2 (MTX) received 0.9% saline/day (po) for 9 days. Groups 3 and 4 received 100 and 200 mg/kg bw/day omega-3 (po), respectively, for 9 days. Groups 5 and 6 received 100 and 200 mg/kg bw/day vitamin C (po), respectively, for 9 days, while group 7 received omega-3 (100 mg/kg bw/day) and vitamin C (100 mg/kg bw/day) (po) for 9 days. All animals in groups 2 to 7 received 20 mg/kg/day MTX (I.P.) once on the 10th day. Our results revealed that MTX significantly induced the elevation of transaminases, alkaline phosphates (ALP), lactate dehydrogenase (LDH), and malonaldehyde (MDA) while depleting the levels of superoxide dismutase (SOD) and glutathione (GSH) when compared to the control group. Treatment with omega-3 fatty acids or vitamin C significantly attenuated the antioxidants and biochemical alterations in a dose-independent manner. Our molecular docking study of ligand-receptor interaction revealed that both ascorbic acid and omega-3 docked well to the binding cavity of LDH with high binding affinities of -5.20 and -4.50 kcal/mol, respectively. The histopathological features were also improved by treatment with omega-3 and vitamin C. The combined form of omega-3 and vitamin C showed a remarkable improvement in the liver enzymes, oxidative stress biomarkers, and the histopathological architecture of the mice. Conclusively, the combination of omega-3 and vitamin C demonstrated a synergistic therapeutic effect against MTX-intoxicated mice, hence representing a potential novel strategy for the management of drug-induced liver disorders.

RESUMO

Current coronavirus disease (COVID-19) is regarded as a primary respiratory and vascular disease leading to acute lung injury (ALI), acute respiratory distress syndrome (ARDS), and endothelial dysfunction (ED) in severe cases. The causative virus of COVID-19 is SARS-CoV-2, which binds angiotensin-converting enzyme 2 (ACE2) for its entry. It has been shown that ED is linked to various COVID-19 complications since endothelial cells are regarded as the chief barrier against SARS-CoV- 2 invasion. SARS-CoV-2-indued ED leads to endotheliitis and thrombosis due to endothelial nitric oxide (NO) inhibition with subsequent vasoconstriction and tissue hypoxia. Loss of vasodilator NO and anti-thrombin factor from endothelial SARS-CoV-2 infection contribute to the progression of vascular dysfunction and coagulopathy. Therefore, NO restoration improves pulmonary function and hinders viral replication during respiratory viral infections, including COVID-19. L-arginine is a semiessential amino acid that has antiviral and immunomodulatory effects as well as improves the biosynthesis of NO in endothelial cells. L-arginine may reduce the risk of ALI through inhibition of generation of peroxynitrite and suppression of the release of proinflammatory cytokines from alveolar macrophages. Of interest, restoration of NO by L-arginine may attenuate SARS-CoV-2 infection through different mechanisms, including reduction binding of SARS-CoV-2 to ACE2, inhibition of transmembrane protease serine-type 2 (TMPRSS2), critical for the activation of SARS-CoV-2 spike protein and cellular entry, inhibition proliferation and replication of SARS-CoV-2, and prevention of SARS-CoV-2-induced coagulopathy. In conclusion, through antiviral and immunomodulatory effects, L-arginine and released NO have mutual and interrelated actions against SARS-CoV-2 infection.

RESUMO

The immune system protects human health from the effects of pathogenic organisms; however, its activity is affected when individuals become infected. These activities require a series of molecules, substrates, and energy sources that are derived from diets. The consumed nutrients from diets help to enhance the immunity of infected individuals as it relates to COVID-19 patients. This study aims to review and highlight requirement and role of macro- and micronutrients of COVID-19 patients in enhancing their immune systems. Series of studies were found to have demonstrated the enhancing potentials of macronutrients (carbohydrates, proteins, and fats) and micronutrients (vitamins, copper, zinc, iron, calcium, magnesium, and selenium) in supporting the immune system's fight against respiratory infections. Each of these nutrients performs a vital role as an antiviral defense in COVID-19 patients. Appropriate consumption or intake of dietary sources that yield these nutrients will help provide the daily requirement to support the immune system in its fight against pathogenic viruses such as COVID-19.

RESUMO

Ursolic acid (UA) is a pentacyclic terpenoid is usually found in the fruit peels and stem bark as secondary metabolites. UA has antiviral, antibacterial, and antiparasitic properties. UA has a wide spectrum of pharmacological activities against different infections. Because of the greatest antiviral and anti-inflammatory properties of UA, so it could be a plausible therapeutic herbal medicine in Covid-19 treatment. Covid-19 is a recent worldwide virulent disease pandemic due to severe acute respiratory coronavirus disease 2 (SARS-CoV-2). The pathogenesis of SARS-CoV-2 infection is related to the direct cytopathic effect and exaggerated immune response by which acute lung injury (ALI) and/or acute respiratory distress syndrome might be developed in critical cases. UA may inhibit main protease of SARS-CoV-2, and inhibits the interface flanked by SARS-CoV-2 viral proteins and its entry point commonly recognized as angiotensin converting enzyme 2 (ACE2). In addition, UA attenuates SARS-CoV-2-induced inflammatory reactions and oxidative stress. Therefore, UA could avert SARS-CoV-2 infection from causing ALI. This opinion proposed that UA might be a potential candidate therapy against Covid-19 and can mitigate post-Covid-19 complications such as lung fibrosis. In this regards, forthcoming studies are reasonable to substantiate the therapeutic role of UA in Covid-19. However, taken into account that Covid-19 is yet to be investigating for further evaluations, therefore, clinical trials are recommended regarding use and dose of UA in Covid-19 treatment, as well as secondary effects.

RESUMO

Breast cancer persists as a diffuse source of cancer despite persistent detection and treatment. Flavonoids, a type of polyphenol, appear to be a productive option in the treatment of breast cancer, because of their capacity to regulate the tumor related functions of class of compounds. Plant polyphenols are flavonoids that appear to exhibit properties which are beneficial for breast cancer therapy. Numerous epidemiologic studies have been performed on the dynamic effect of plant polyphenols in the prevention of breast cancer. There are also subclasses of flavonoids that have antioxidant and anticarcinogenic activity. These can regulate the scavenging activity of reactive oxygen species (ROS) which help in cell cycle arrest and suppress the uncontrolled division of cancer cells. Numerous studies have also been performed at the population level, one of which reported a connection between cancer risk and intake of dietary flavonoids. Breast cancer appears to show intertumoral heterogeneity with estrogen receptor positive and negative cells. This review describes breast cancer, its various factors, and the function of flavonoids in the prevention and treatment of breast cancer, namely, how flavonoids and their subtypes are used in treatment. This review proposes that cancer risk can be reduced, and that cancer can be even cured by improving dietary intake. A large number of studies also suggested that the intake of fruit and vegetables is associated with reduced breast cancer and paper also includes the role and the use of nanodelivery of flavonoids in the healing of breast cancer. In addition, the therapeutic potential of orally administered phyto-bioactive compounds (PBCs) is narrowed because of poor stability and oral bioavailability of compounds in the gastrointestinal tract (GIT), and solubility also affects bioavailability. In recent years, creative nanotechnology-based approaches have been advised to enhance the activity of PBCs. Nanotechnology also offers the potential to become aware of disease at earlier stages, such as the detection of hidden or unconcealed metastasis colonies in patients diagnosed with lung, colon, prostate, ovarian, and breast cancer. However, nanoformulation-related effects and safety must not be overlooked. This review gives a brief discussion of nanoformulations and the effect of nanotechnology on herbal drugs.

RESUMO

Vinpocetine (VPN) is a synthetic ethyl-ester derivative of the alkaloid apovincamine from Vinca minor leaves. VPN is a selective inhibitor of phosphodiesterase type 1 (PDE1) that has potential neurological effects through inhibition of voltage-gated sodium channel and reduction of neuronal calcium influx. VPN has noteworthy antioxidant, anti-inflammatory, and anti-apoptotic effects with inhibitory effect on glial and astrocyte cells during and following ischemic stroke (IS). VPN is effective as adjuvant therapy in the management of epilepsy; it reduces seizure frequency by 50% in a dose of 2 mg/kg/day. VPN improves psychomotor performances through modulation of brain monoamine pathway mainly on dopamine and serotonin, which play an integral role in attenuation of depressive symptoms. VPN recover cognitive functions and spatial memory through inhibition of hippocampal and cortical PDE1 with augmentation of cyclic adenosin monophosphate and cyclic guanosin monophosphate ratio, enhancement of cholinergic neurotransmission, and inhibition of neuronal inflammatory mediators. Therefore, VPN is an effective agent in the management of IS and plays an integral role in the prevention and attenuation of poststroke epilepsy, depression, and cognitive deficit through direct cAMP/cGMP-dependent pathway or indirectly through anti-inflammatory and antioxidant effects.

Parameters measured were blood urea, serum creatinine, serum malondialdehyde, superoxide dismutase, glutathione reductase, neutrophil gelatinase associated lipocalin, kidney injury molecules-1, Interleukin-18and cystatin-c. Anthropometric measurements and estimated glomerular filtration rate were also noted. SPSS 20 was used for data analysis. RESULTS: Of the 30 rats, the three groups had 10(33.3%) each. Berberine reduced blood urea, serum creatinine, malondialdehyde, neutrophil gelatinase associated lipocalin, kidney injury molecules-1 and Interleukin-18 significantly compared to diclofenac-induced acute kidney injury (p<0.01 each). Berberine improved anti-oxidant capacity through significant elevation of superoxide dismutase and glutathione reductase sera levels (p<0.01 each). CONCLUSIONS: Berberine was found to be an effective agent in the attenuation of diclofenac-induced acute kidney injury through the modulation of pro-inflammatory and oxidative stress biomarkers.

RESUMO

OBJECTIVE: To elucidate the protective effect of berberine on olanzapine induced-metabolic syndrome. METHODS: This prospective experimental study involved thirty Sprague-Dawley male rats which were divided into three groups. Group A (n=10): Rats treated with distilled water, Group B (n=10): Rats treated with olanzapine, Group C (n=10): Rats treated with olanzapine plus berberine. The duration of the study was 8 weeks, baseline and follow up data were evaluated. Fasting blood glucose(FBG) total cholesterol (TC), triglyceride (TG) and high-density lipoprotein (HDL), Low density lipoprotein (LDL), atherogenic index of plasma (AI), fasting serum insulin level, insulin resistance, ß- cell function and insulin sensitivity were evaluated.SPSS 20. RESULTS: Olanzepine led to significant deterioration in gluco-metabolic profile compared with control P<0.01. Olanzapine plus berberine improved body weight, FBG, FSI, HOMA-IR and QUICKI compared with olanzapine P=0.0001. CONCLUSIONS: Berberine attenuates olanzapine induced-metabolic via amelioration of gluco-lipid disturbances.

RESUMO

OBJECTIVE: To evaluate the nephro-protective effects of berberine and/or pentoxifylline on the reduction of diclofenac-induced acute kidney injury in rats. METHODS: The experimental study was conducted at the Department of Pharmacology, College of Medicine, Mustansiriya University, Baghdad, Iraq, from February to April, 2018, and comprised fifty male Sprague-Dawley rats aged 3-4 months and weighing 250-400 grams each. They were divided into five equal groups and were treated for 12 days. Group 1 rats were treated with distilled water plus normal saline, Group 2 with distilled water plus diclofenac, Group 3 with berberine plus diclofenac, Group 4 with pentoxifylline plus diclofenac, and Group 5 rats were treated with berberine, pentoxifylline and diclofenac. Blood urea, creatinine, Neutrophil Gelatinase Associated Lipocalin (NGAL), kidney injury molecules (KIM-1) and cystatin-C were used to measure the severity of AKI. RESULTS: Diclofenac led to significant AKI by significant elevation of blood urea, serum creatinine level, KIM-1, NGAL. Treatment with berberine showed no significant effect on all biomarkers level compared to diclofenac group except on serum KIM-1 level which was also seen in pentoxifylline group. Whereas, combination of berberine and pentoxifylline led to more significant effect in reduction of all renal biomarkers. CONCLUSIONS: Combination of berberine with pentoxifylline led to more significant reno-protective than either berberine or pentoxifylline when used alone on diclofenac induced-AKI.

RESUMO

OBJECTIVE: To evaluate the cardio-protective effect of Ginkgo Biloba (GB) on doxorubicin induced-cardiotoxicity. METHODS: The experimental study was conducted at the College of Medicine, Mustansiriya University, Baghdad, Iraq, from January to March, 2016, and comprised thirty Wistar Sprague male rats aged 3-4 months and weighing 200-400 g. The rats were divided into three equal groups (n=10); Group І (control): rats were treated with distilled water, Group ІІ (doxorubicin): rats were treated with distilled water and doxorubicin 20 mg/kg, and Group ІІІ (GB): rats were treated with GB and doxorubicin 20mg/kg. Serum malondialdehyde (MDA), glutathione reductase (GSH), lipid peroxidise (LPO), tumour necrosis factor-alpha (TNF-α), cardiac troponin (cTnI), brain natriuretic peptide (BNP) and caspase-3 (Cas-3) were measured using enzyme-linked immunosorbent assay kits. SPSS 20 was used to compare the effect GB with doxorubicin on the biomarkers of doxorubicin induced-cardiotoxicity. RESULTS: Doxorubicin led to cardiotoxicity through elevation of cTnI, BNP, Cas-3 and LPO compared with controls (p<0.01).Also, MDA and TNF-α were elevated while; GSH was decreased significantly (p<0.01) compared with controls. Co-administration of GB with doxorubicin led to significant reduction in cTnI, Cas-3 sera levels with elevation in GSH serum level significantly (p<0.05). The effect of GB on BNP, LPO, MDA and TNF-α was insignificant (p>0.05) compared with the doxorubicin. CONCLUSIONS: GB has significant cardio-protective effect through attenuation of oxidative stress during doxorubicin induced-cardiotoxicity in rats.
