RESUMO
The research aims to identify the inhibitory potential of natural dietary phytochemicals against non-insulinotropic target protein alpha-glucosidase and its possible implications to diabetes mellitus type 2. A data set of sixteen plant-derived dietary molecules viz., 4,5-dimethyl-3-hydroxy-2(5H)-furanone, apigenin, bromelain, caffeic acid, cholecalciferol, dihydrokaempferol 7-o-glucopyranoside, galactomannan, genkwanin, isoimperatorin, luteolin, luteolin 7-o-glucoside, neohesperidin, oleanoic acid, pelargonidin-3-rutinoside, quercetin, and quinic acid were taken to accomplish molecular docking succeeded by their comparison with known inhibitors including acarbose, miglitol, voglibose, emiglitate, and 1-deoxynojirimycin. Among all phyto-compounds, bromelain (ΔG: -9.54 kcal/mol), cholecalciferol (-8.47 kcal/mol), luteolin (-9.02 kcal/mol), and neohesperidin (-8.53 kcal/mol) demonstrated better binding interactions with alpha-glucosidase in comparison to the best-known inhibitor, acarbose (ΔG: -7.93 kcal/mol). Molecular dynamics simulation of 10 ns duration, CYP450 site of metabolism identification, and prediction of activity spectra for substances depicted the bromelain as the most stable inhibitor compared to luteolin and acarbose. Findings of molecular interactions, molecular dynamics study, metabolism, and biological activity prediction proved bromelain as a potential alpha-glucosidase inhibitor. Thus, bromelain might be helpful as an insulin-independent therapeutic molecule towards controlling and managing diabetes mellitus type 2.

In view of many complications of diabetes, kidney failure is considered as one of the main complications. The oxidative stress-induced due to persistent hyperglycemic conditions is the major cause of kidney disease. The present study was designed to explore the nephroprotective efficacy of polyherbal (PH) extract in a diabetic model induced by streptozotocin (STZ). STZ (55 mg/kg body weight, intraperitoneal) was injected in overnight fasting rats to develop the diabetic experimental model. Effect on kidney injury was evaluated by investigating biochemical and histological evidences in renal tissue after 56 days of treatment of PH extract. Results showed the high glucose level in STZ treated rats that suggested hyperglycemia persistence along with the successful establishment of nephropathy in diabetic rats with altered renal function, inflammatory cytokines level as well as oxidative and nitrosative stress. Administration of PH extract significantly improved the glycemic condition, glomerular function and proximal reabsorptive markers. Further, elevated pro-inflammatory cytokines levels and disturbed redox status were restored. Moreover, findings were fostered and substantiated by histopathological examinations. Our work strongly proposes that the nephroprotective effect of the PH extract on renal damage could be attributed due to its anti-inflammatory and antioxidant properties. Thus, PH extract could have potential as a pharmaceutical drug for diabetes mellitus (DM). Additional long-term study or clinical trial is required for further investigations.

Cancer is recognized as the leading cause of death worldwide. The hippo signaling pathway regulates organ size by balancing cell proliferation and cell death; hence dysregulation of the hippo pathway promotes cancerlike conditions. miRNAs are a type of noncoding RNA that have been shown to regulate gene expression. miRNA levels are altered in various classes of cancer. Researchers have also uncovered a crosslinking between miRNAs and the hippo pathway, which has been linked to cancer. The components of the hippo pathway regulate miRNA synthesis, and various miRNAs regulate the components of the hippo pathway both positively and negatively, which can lead to cancerlike conditions. In the present review article, the mechanism behind the hippo signaling pathway and miRNAs biogenesis and crosslinks between miRNAs and the hippo pathway, which result in cancer, shall be discussed. Furthermore, the article will cover miRNArelated therapeutics and provide an overview of the development of resistance to anticancer drugs. Understanding the underlying processes would improve the chances of developing effective cancer treatment therapies.

The current study aimed to investigate in vitro anthelmintic efficacy of two medicinally important plants against Haemonchus contortus in small ruminants. Fruit peel of Punica granatum Linn. (vern. Anar), leaves and roots of Berberis lycium Royle (vern. Sumbal) were tested for their anthelmintic efficacy. Methanolic extracts of the test plants from various plant parts were tested for anthelmintic efficacy against the Haemonchus contortous using albendazole as a reference standard. The results revealed that both the plant extracts exhibited potent anthelmintic activity at concentrations higher than 50 mg/mL when tested against their respective standard drug. In case of Berberis lycium Royle when the results were compared, methanolic roots extracts showed more potent activity as compared to leaves extracts at the same concentration. It was observed that the in vitro anthelmintic potential of Punica granatum Linn. fruit peel and Berberis lyceium Royale root can be used to treat helminth infections after in vivo trails.
