<p class="Abstract">The present study aimed at the evaluation of anti-hyperglycemic and hepatoprotective potential of a new drug candidate, 5-[(4-chlorophenoxy) methyl]-1,3,4-oxadiazole-2-thiol (OXCPM) through in vitro and in vivo assays, respectively. The compound displayed excellent dose-dependent ɑ-amylase (28.0-92.0%), ɑ-glucosidase (40.3-93.1%) and hemoglobin glycosylation (9.0%-54.9%) inhibitory effects and promoted the uptake of glucose by the yeast cells (0.2 to 26.3%). The treatment of the isoniazid- and rifampicin- (p.o., 50 mg/kg of each) intoxicated rats with OXCPM (100 mg/kg, p.o.) resulted in restoring the normal serum levels of the non-enzymatic (total bilirubin, total protein and albumin) and bringing about a remarkable decrease in the levels of enzymatic (alanine transaminases, aspartate transaminases and alkaline phosphatase) biomarkers. The molecular docking studies indicated high binding affinity of the compound for hyperglycemia-related protein targets; fructose-1,6-bisphosphatase, beta<sub>2</sub>-adrenergic receptors and glucokinase. The results indicate that OXCPM may not only reduce hyperglycemia by enzyme inhibition but also the disease complications through protection of hemoglobin glycosylation and hepatic injury.</p><p class="Abstract"><strong>Video Clip of Methodology:</strong></p><p class="Abstract">Glucose uptake by yeast cells:   4 min 51 sec   <a href="https://www.youtube.com/v/8cJkuMtV0Wc">Full Screen</a>   <a href="https://www.youtube.com/watch?v=8cJkuMtV0Wc">Alternate</a></p>

A series of benzimidazolyl-1,3,4-oxadiazoles (7a-k) were synthesized and evaluated for in vitro anticancer activity against HeLa, MCF7, A549, and HEK293 cell lines. The results indicate that compounds 7b, 7j and 7k have shown excellent anticancer activity and while most of the compounds were non toxic to normal HEK293 cell lines. Molecular docking results of the synthesized compounds with the target Pin1 protein were also discussed.

Introduction: Feruloyl Sucrose Esters (FSEs) are a class of Phenylpropanoid Sucrose Esters (PSEs) widely distributed in plants. They were investigated as potential selective Alpha Glucosidase Inhibitors (AGIs) to eliminate the side effects associated with the current commercial AGIs. The latter effectively lowers blood glucose levels in diabetic patients but causes severe gastrointestinal side effects. Methods: Systematic structure-activity relationship (SAR) studies using in silico, in vitro and in vivo experiments were used to accomplish this aim. FSEs were evaluated for their in vitro inhibition of starch and oligosaccharide digesting enzymes α-glucosidase and α-amylase followed by in silico docking studies to identify the binding modes. A lead candidate, FSE 12 was investigated in an STZ mouse model. Results: All active FSEs showed desired higher % inhibition of α-glucosidase and desired lower inhibition of α-amylase in comparison to AGI gold standard acarbose. This suggests a greater selectivity of the FSEs towards α-glucosidase than α-amylase, which is proposed to eliminate the gastrointestinal side effects. From the in vitro studies, the position and number of the feruloyl substituents on the sucrose core, the aromatic ‘OH’ group, and the diisopropylidene bridges were key determinants of the % inhibition of α-glucosidase and α-amylase. In particular, the diisopropylidene bridges are critical for achieving inhibition selectivity. Molecular docking studies of the FSEs corroborates the in vitro results. The molecular docking studies further reveal that the presence of free aromatic ‘OH’ groups and the substitution at position 3 on the sucrose core are critical for the inhibition of both the enzymes. From the in vitro and molecular docking studies, FSE 12 was selected as a lead candidate for validation in vivo. The oral co-administration of FSE 12 with starch abrogated the increase in post-prandial glucose and significantly reduced blood glucose excursion in STZ-treated mice compared to control (starch only) mice. Conclusion: Our studies reveal the potential of FSEs as selective AGIs for the treatment of diabetes, with a hypothetical reduction of side effects associated with commercial AGIs.
