Inhibition of urease results in Helicobacter pylori growth arrest in the stomach, promoting urease as promising targets for gastrointestinal ulcer therapy. Twenty hybrid derivatives of flavonoid scaffold and hydroxamic acid, β-hydroxy-β-phenylpropionylhydroxamic acids, were therefore synthesized and evaluated against H. pylori urease. Biological evaluation of these compounds showed improved urease
尿素酶的抑制导致幽门螺杆菌在胃中的生长停滞,从而促进尿素酶成为胃肠道溃疡治疗的有希望的靶标。因此,合成了黄酮类支架和异羟肟酸的二十种杂合衍生物,β-羟基-β-苯基丙酰基异羟肟酸,并针对幽门螺杆菌脲酶进行了评估。这些化合物的生物学评估表明,尿素酶抑制作用得到改善,表现出微摩尔至中纳摩尔级的IC 50值。最重要的是,3-(3-氯苯基)-3-羟基丙酰基-异羟肟酸(6g)表现出高效能,IC 50为0.083±0.004μM,K i为0.014±0.003μM,表明6g是开发新型抗溃疡药的优秀候选者。为了首次了解晶体学和动力学研究之间的矛盾,提出了一种竞争机制和非竞争机制的混合物,这是我们的分子对接研究所支持的。
