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.

A practical method for the synthesis of 3,5-disubstituted isoxazoles via cyclization of β-fluoro enones with sodium azide was disclosed. Density functional theory (DFT) calculation indicated that both (1) the azirine formation followed by intramolecular rearrangement and (2) direct enolate O-attack via 5-exo-trig cyclization of vinyl azide were possible for the isoxazole formation.

A facile oxidative heterocyclization of commercially available amines and tert-butyl nitrite with alkynes or alkenes leading to isoxazoles or isoxazolines is described. The unprecedented strategy of the oxidation of an amine directly to a nitrile oxide was used in this cyclization process. This reaction is highly efficient, regiospecific, operationally simple, mild, and tolerant of a variety of functional groups. Control experiments support a nitrile oxide intermediate mechanism for this novel class of oxidative cyclization reactions. Moreover, synthetic applications toward bioactive molecular skeletons and the late-stage modification of drugs were realized.
