  In the recent past, we have synthesized and reported different derivatives of oxadiazoles as potential α-glucosidase inhibitors, keeping in mind, the pharmacological aspects of oxadiazole moiety and in continuation of our ongoing research on the chemistry and bioactivity of new heterocyclic compounds.

  1,3,4-Oxadiazole derivatives (1-14) have been synthesized and characterized by different spectroscopic techniques such as 1H-, 13C-NMR and HREI-MS.

  The synthetic derivatives were screened for α-glucosidase inhibitory potential. All compounds exhibited good inhibitory activity with IC50 values ranging between 0.80 ± 0.1 to 45.1 ± 1.7 μM in comparison with the standard acarbose having IC50 value 38.45 ± 0.80 μM.

  Thirteen compounds 1-6 and 8-14 showed potential inhibitory activity as compared to the standard acarbose having IC50 value 38.45 ± 0.80 μM, however, only one compound 7 (IC50 = 45.1 ± 1.7 μM) was found to be less active. Compound 14 (IC50 = 0.80 ± 0.1 μM) showed promising inhibitory activity among all synthetic derivatives. Molecular docking studies were also conducted for the active compounds to understand the ligand-enzyme binding interactions.

  背景：最近，我们合成并报告了不同的氧代二唑衍生物作为潜在的α-葡萄糖苷酶抑制剂，考虑到氧代二唑基团的药理学方面，并延续我们对新异环化合物的化学和生物活性研究。 方法：合成和表征了1,3,4-氧代二唑衍生物（1-14），并通过不同的光谱技术如1H-、13C-NMR和HREI-MS进行了表征。 结果：合成的衍生物被筛选用于α-葡萄糖苷酶抑制潜力。所有化合物在抑制活性方面表现出良好的活性，IC50值在0.80±0.1至45.1±1.7μM之间，与标准药物阿卡波糖的IC50值38.45±0.80μM相比。 结论：化合物1-6和8-14中的十三种化合物显示出潜在的抑制活性，与具有IC50值38.45±0.80μM的标准药物阿卡波糖相比，然而，只有一种化合物7（IC50=45.1±1.7μM）显示出较低的活性。化合物14（IC50=0.80±0.1μM）在所有合成衍生物中表现出有希望的抑制活性。还进行了活性化合物的分子对接研究，以了解配体-酶结合相互作用。

  2-Amino-substituted 1,3,4-oxadiazoles and 1,3,4-thiadiazoles were synthesized via condensation of semicarbazide/thiosemicarbazide and the corresponding aldehydes followed by I-2-mediated oxidative C-O/C-S bond formation. This transition-metal-free sequential synthesis process is compatible with aromatic, aliphatic, and cinnamic aldehydes, providing facile access to a variety of diazole derivatives bearing a 2-amino substituent in an efficient and scalable fashion.
