derivatives 3a–3u was designed and synthesized by a simple and facile synthetic route. The biological assay revealed that majority of compounds displayed modest inhibitory activity against thymidine phosphorylase at low micromolar concentrations (IC50 173.23 ± 3.04 to 14.40 ± 2.45 μM). In the current study the most active compounds were 3h and 3q with IC50 values 14.40 ± 2.45 and 17.60 ± 1.07 μM, respectively
基于胸腺嘧啶磷酸化酶抑制剂被认为是潜在的抗肿瘤剂这一事实,通过简单而又容易的合成途径设计并合成了一系列新型的恶二唑衍生物3a - 3u。生物学分析表明,大多数化合物在低微摩尔浓度(IC 50 173.23±3.04至14.40±2.45μM)下显示出对胸苷磷酸化酶的适度抑制活性。在本研究中,活性最高的化合物为3h和3q,IC 50值分别为14.40±2.45和17.60±1.07μM。对活性最强的化合物(3h,3k,3o – 3q)以显示其绑定模式。
