    Abstract Background: The present clinical trial was conducted to evaluate the efficacy and tolerability of a standardized saw palmetto oil containing 3% β-sitosterol in the treatment of benign prostate hyperplasia (BPH) and androgen deficiency.
    Methods: Subjects aged 40-65 years with symptomatic BPH were randomized to 12-week double-blind treatment with 500 mg doses of β-sitosterol enriched saw palmetto oil, conventional saw palmetto oil and placebo orally in the form of capsules (n = 33 in each group). BPH severity was determined using the International Prostate Symptom Score (IPSS), uroflowmetry, serum measurement of prostate specific antigen (PSA), testosterone and 5α-reductase. During the trial, the androgen deficiency was evaluated using Aging Male Symptoms (AMS) scale, the Androgen Deficiency in the Aging Male (ADAM) questionnaire, serum levels of free testosterone.
    Results: Subjects treated with β-sitosterol enriched saw palmetto oil showed significant decrease in IPSS, AMS and ADAM scores along with reduced postvoiding residual volume (p < 0.001), PSA (p < 0.01) and 5α-reductase from baseline to end of 12-week treatment as compared to placebo. There was also a significant increment in the maximum and average urine flow rate (p < 0.001), and serum free testosterone level of subjects treated with enriched saw palmetto oil as compared to placebo.
    Conclusion: This study demonstrates the efficacy of β-sitosterol enriched saw palmetto oil superior to conventional oil thus extending the scope of effective BPH and androgen deficiency treatment with improved quality of life through the intake of functional ingredients.

    Abstract Design and development of an effective compound to combat COVID-19 is clearly critical in the current circumstances. Therefore, it is of interest to document the molecular docking analysis data of the cellular receptor Glucose regulated protein 78 (GRP78) with Withaferin A from Withania somnifera in the context of COVID-19 pandemic for further consideration. Here, we report the optimal interaction features of withaferin A, artemisinin, curcumin and andrographolide with the GRP78 receptor having low binding energies (-8.7, -7.89, -6.21 and -6.17 kcal/mol respectively) in this report. In order to gain additional insights, the interaction pattern of compounds with SARS-CoV-2 main protease (Mpro) was studied.

    Abstract β‐caryophyllene (BCP), a natural sesquiterpene present in plants, is a selective agonist of cannabinoid receptor type‐2 (CB2) of the endocannabinoid system. In this study, we have prepared an extract from Piper nigrum (black pepper) seeds using supercritical fluid extraction, standardized to contain 30% BCP (Viphyllinᵀᴹ). The beneficial effects of prophylactic treatment with Viphyllin on cognitive functions were demonstrated in Scopolamine‐induced dementia model mice. Male Swiss albino mice (25–30 g) were administered with Viphyllin (50 mg and 100 mg/kg body weight p.o.) or donepezil (1.60 mg/kg) for 14 days. Subsequently, cognitive deficits were induced by treating the animals intraperitoneally with Scopolamine (0.75 mg/kg). The cognitive behavior of mice was evaluated using a novel object recognition test (NORT) and Morris water maze (MWM) test. The brain homogenates were studied for biochemical parameters including cholinesterase activities and antioxidant status. Western blot analysis was performed to investigate the mechanism of action. Viphyllin dose dependently improved the recognition and spatial memory and cholinergic functions in Scop‐treated mice. The extract was found protective against Scop‐induced oxidative damage and histopathologic changes in the brain. At 100 mg/kg Viphyllin markedly reduced the proBDNF/mBDNF ratio (p < .05) and augmented the TrkB expression (p < .01). Viphyllin (100 mg/kg) was found to be neuroprotective by reducing the Scop‐induced upregulation of p‐JNK and p‐p38 MAPK proteins, Bax/Bcl‐2 ratio, and caspase activation in the brain. Viphyllin also exerted anti‐inflammatory effects by downregulating Cox‐2, TNF‐α, and NOS‐2 in Scop‐induced mice (p < .05). To summarize, our data encourage Viphyllin as a functional ingredient/dietary supplement for brain health and cognition. PRACTICAL APPLICATIONS: Black pepper is a culinary spice having several medicinal attributes. Essential oils in the seeds of the plant give aroma and flavor to it. Here we have prepared an extract from the seeds of black pepper using supercritical fluid extraction, characterized for the presence of β‐caryophyllene (not <30%). This research work further validates the neuroprotective mechanism of the extract in Scopolamine‐induced cognitive impairment model mice. The findings from this study strongly suggest the beneficial neuroactive properties of black pepper seed extract having the presence of BCP, a CB2 receptor agonist. It can thus be used potentially as a functional food ingredient for cognition and brain function.

    Abstract Background: Withania somnifera
    Objective: In the present study, we have evaluated the antiproliferative activity of a standardized
    Materials and methods: The cytotoxicity of Viwithan was determined using thiazolyl blue tetrazolium blue assay and crystal violet staining. The apoptotic changes in B16F1 cells following treatment with Viwithan were observed by acridine orange/ethidium bromide (AO/EB) staining and DNA fragmentation assay. The binding affinity of withanolides in Viwithan with antiapoptotic proteins B-cell lymphoma 2, B-cell lymphoma-extra large, and myeloid cell leukemia 1 (MCL-1) were studied using
    Results: The half maximal inhibitory concentration (IC50) values of Viwithan against liver hepatocellular carcinoma, Henrietta Lacks cervical carcinoma cells, human colorectal carcinoma cell line, and Ehrlich ascites carcinoma cells were 1830, 968, 2715, and 633 μg/ml, respectively. Interestingly, Viwithan was highly effective against B16F1 cells with an IC50 value of 220 μg/ml after 24 h treatment. The morphological alterations of apoptotic cell death were clearly observed in the AO/EB-stained cells after treatment with Viwithan. Viwithan induced late apoptotic changes in treated B16F1 cells as evident by the ladder formation of fragmented DNA in a time-dependent manner. The findings of molecular docking showed that withanolides present in Viwithan have a more binding affinity with the antiapoptotic proteins, particularly MCL-1.
    Conclusion: We have reported for the first time that Viwithan with 5% withanolides has a potent cytotoxic effect, particularly against B16F1 murine melanoma cells among the different cancer cell lines tested.
    Summary: The present study reports for the first time that Viwithan, a standardized 5%

    Abstract Propionibacterium acnes (P. acnes) is a rod-shaped, anaerobic, Gram-positive, opportunistic bacterium, that causes infectious and inflammatory diseases, such as acne vulgaris synovitis-acnes-pustulosis-hyperostosis-osteitis syndrome, sarcoidosis, and prostate cancer. Earlier evidence suggests that essential oils have been used to treat skin diseases and disorders since ancient times. Thus, the present study investigated the anti-microbial activity of 28 essential oils from nine families, including Lamiaceae, Poaceae, Geraniaceae, Myrtaceae, Zingiberaceae, Verbenaceae, Cupressaceae, Asteraceae, and Cyperaceae against P. acnes. The anti-bacterial susceptibility and efficacy of the essential oils were examined using paper disc diffusion, broth micro-dilution, time-kill kinetics and ROS assays. P. acnes was cultured under anaerobic conditions. The kinetic process evaluated the time and dose-dependent effects of essential oils. The alteration in membrane potential and ROS production were measured in terms of mean fluorescence intensity. Consequently, the chemical composition of essential oil was analyzed by GC and GC/MS analysis. Eighteen essential oils inhibited the growth of P. acnes with a clear zone of 5 to 20.33 mm. Eucalyptus, Mentha, Palmarosa, Lemongrass, Citronella, Geranium, Patchouli, Ocimum, and Clarysage possess better antibacterial activity (ZGI: 10.33 ± 2.31 mm - 20.33 ± 4.72 mm). Lippia oil showed the minimum inhibitory concentration (MIC) of 0.125% v/v, and the MIC of Mentha, Ocimum, and Patchouli oils ranged from 0.25 to 0.50% v/v. Further, the concentration and time-kill kinetic study indicated that Lippia alba and O. sanctum oils suppress the growth at MIC till 12 h and at 2 × MIC until 72 h. Moreover, the oils induced ROS production with one fold change at 2 × MIC. In addition, O. sanctum oil altered the membrane integrity with a fold change of 1.0 and 2.0 at MIC and 2 × MIC, respectively, while L. alba oil modified a fold change of 1.0. The essential oils suppressed bacterial growth by inducing ROS and modulating membrane integrity. Therefore, L. alba and O. sanctum essential oils could be used as an alternative to chemicals/drugs for treating microbe-associated acne problems.

    Abstract DNA methylation provides a crucial epigenetic mark linking genetic variations to environmental influence. We have analyzed array-based DNA methylation profiles of 160 human retinas with co-measured RNA-seq and >8 million genetic variants, uncovering sites of genetic regulation in cis (37,453 methylation quantitative trait loci and 12,505 expression quantitative trait loci) and 13,747 DNA methylation loci affecting gene expression, with over one-third specific to the retina. Methylation and expression quantitative trait loci show non-random distribution and enrichment of biological processes related to synapse, mitochondria, and catabolism. Summary data-based Mendelian randomization and colocalization analyses identify 87 target genes where methylation and gene-expression changes likely mediate the genotype effect on age-related macular degeneration. Integrated pathway analysis reveals epigenetic regulation of immune response and metabolism including the glutathione pathway and glycolysis. Our study thus defines key roles of genetic variations driving methylation changes, prioritizes epigenetic control of gene expression, and suggests frameworks for regulation of macular degeneration pathology by genotype-environment interaction in retina.

    Abstract The aim of this review is to encapsulate the synthetic protocols and medicinal aspects of a wide range of heterocyclic compounds using the Vilsmeier-Haack (V. H.) reagent. These derivatives act as excellent precursors having different aryl ring functionalities and could be used for the synthesis of a variety of heterocyclic scaffolds. The V. H. reagent, a versatile reagent in organic chemistry, is used to formylate various heterocyclic compounds of medicinal interest. Due to the different chemical interactions, efficacy, and potency of V. H. reagents, plenty of heterocyclic compounds can be synthesized which serve as a constituent in various novel medications and acts as a bridge between biology and chemistry. These carboxylate moieties can effectively cooperate as precursors for several multi-component reactions (MCR) including Strecker synthesis, Bucherer-Berg reaction and post-MCR cyclization, modified variants with various pharmaceutical applications such as anti-tumor, anti-convulsant, anti-chitosomal and so on.
