4-oxadiazoles (7–31) were designed, synthesized and tested in vitro against E. coli TP (EcTP). Compound 7 emerged as potent TP inhibitor with an IC50 value of 3.50 ± 0.01 μM. Docking studies were carried out using GOLD software on thymidine phosphorylase from human (hTP) and E. coli (EcTP). Various hydrogen bonding, hydrophobic interactions, and π-π stacking were observed between designed molecules and the
为了设计和开发用于治疗肿瘤疾病的新药物,对胸苷磷酸化酶(TP)的抑制作用一直在进行研究。作为鉴定TP抑制剂的一部分,我们对化合物的收集物进行了基于结构的虚拟筛选(SBVS)。基于从虚拟筛选片段的结构中获得的见识,以1,3,4-恶二唑为基本结构特征设计了支架,并进行了SAR研究以优化该支架。设计,合成和研究了二十五个新颖的双吲哚连接的1,3,4-恶二唑类化合物(7 – 31),并针对大肠杆菌TP(Ec TP)进行了体外测试。化合物7出现为强效TP抑制剂,IC 50值为3.50±0.01μM。使用GOLD软件对来自人(h TP)和大肠杆菌(Ec TP)的胸苷磷酸化酶进行了对接研究。在设计的分子和研究的酶的活性位点氨基酸残基之间观察到各种氢键,疏水相互作用和π-π堆积。
