Background: α-Glucosidase inhibitors have occupied a significant position in the treatment of type 2 diabetes. In this respect, the development of novel and efficient non-sugar-based inhibitors is in high demand. Objective: Design and synthesis of new 5-arylisoxazole-1,3,4-thiadiazole hybrids possessing α-glucosidase inhibitory activity were developed. Methods: Different derivatives were synthesized by the reaction of various 5-arylisoxazole-3-carboxylic acids and ethyl 2-((5-amino-1,3,4-thiadiazol-2-yl)thio)acetate. Finally, they were evalu-ated for their α-glucosidase inhibitory activity. Results: It was found that ethyl 2-((5-(5-(2-chlorophenyl)isoxazole-3-carboxamido)-1,3,4-thiadiazol-2-yl)thio)acetate (5j) was the most potent compound (IC50 = 180.1 μM) compared with acarbose as the reference drug (IC50 = 750.0 μM). Also, the kinetic study of 5j revealed a competitive inhibition and docking study results indicated desired interactions of that compound with amino acid residues located close to the active site of α-glucosidase. Conclusion: Good α-glucosidase inhibitory activity obtained by the title compounds introduced them as an efficient scaffold, which merits to be considered in anti-diabetic drug discovery developments.

Antibiotic resistance among clinically significant bacterial pathogens is becoming a prevalent threat to public health, and new antibacterial agents with novel mechanisms of action hence are in an urgent need. Utilizing computational docking method and structure-based optimization strategy, we rationally designed and synthesized two series of isoxazol-3-yl- and isoxazol-5-yl-containing benzamide derivatives that targeted the bacterial cell division protein FtsZ. Evaluation of their activity against a panel of Gram-positive and -negative pathogens revealed that compounds B14 and B16 that possessed the isoxazol-5-yl group showed strong antibacterial activity against various testing strains, including methicillin-resistant Staphylococcus aureus and penicillin-resistant S. aureus. Further molecular biological studies and docking analyses proved that the compound functioned as an effective inhibitor to alter the dynamics of FtsZ self-polymerization via a stimulatory mechanism, which finally terminated the cell division and caused cell death. Taken together, these results could suggest a promising chemotype for development of new FtsZ-targeting bactericidal agent.
