A series of novel pyrrolo[2,3-d]pyrimidine derivatives was designed and synthesized as thymidylate synthase (TS) inhibitors. Molecular design was performed on the human TS complex model built on the basis of the reported structure of TS-deoxyuridinemonophosphate (dUMP)-CB3717 ternary complex. From a docking study, we expected that a one-carbon bridge between pyrrolo[2,3-d]pyrimidine and an aromatic
设计并合成了一系列新颖的吡咯并[2,3-d]嘧啶衍生物,作为胸苷酸合酶(TS)抑制剂。在人TS复合物模型上进行了分子设计,该模型基于已报道的TS-脱氧尿苷单磷酸(dUMP)-CB3717三元复合物的结构建立。从对接研究中,我们预计吡咯并[2,3-d]嘧啶与芳环之间的一个碳桥是合适的。此外,我们发现,桥碳可以被烷基取代以填充未占用的空间。基于此设计,我们合成了5个带有一个碳桥的吡咯并[2,3-d]嘧啶衍生物,并评估了它们的TS抑制活性。所有合成的化合物都比化合物2(LY231514)更有效地抑制TS,C8-乙基类似物(7)对TS表现出显着的抑制活性(IC50 = 0。
