compounds at the active site of the enzymes. The two most active adamantane analogs against urease are those with m- and o-fluoro substitution due to specific interactions with CME592, HOH1918 and GLN635 (3.04, 2.74, and 3.21 Å). Ortho analogs interact with GLN635 (3.04, 3.10 Å). The two analogs having diflouro and tri flouro methyl group, showed a slight lower activity as compared to the first two compounds
据报道,超声合成26种金刚烷胺衍生物 ( 3-28 ),包括 7 种新化合物,与文献数据相比,合成时间显着缩短,产率百分比提高。这里首次报道了对所有金刚烷胺衍生物的脲酶和α-葡萄糖苷酶抑制活性的评估。与标准药物乙酰氧肟酸(IC 50 = 20.3 ± 0.4 µM) 相比,三种化合物被发现是有效的脲酶抑制剂(IC 50 = 9.32 ± 1.01 µM,至 IC 50 = 11.32 ± 1.05 µM)。与标准药物阿卡波 糖(IC50 = 875.75 ± 2.08 µM)。进行动力学研究以研究α-葡萄糖苷酶的竞争性和非竞争性抑制以及脲酶的混合型抑制。检查所有化合物以及母体药物对人成纤维细胞 (BJ) 细胞系的细胞毒性。四种化合物被发现是有毒的,而其余的是无毒的。 此外,进行了计算机研究以预测化合物在酶活性位点的结合相互作用。由于与 CME592、HOH1918 和 GLN635 的特定相互作用(3
