In search for a novel chemotype to develop topoisomerase I (Top1) inhibitors, the pyrazolo[1,5-a]quinazoline nucleus, structurally related to the indenoisoquinoline system precursor of well-known Top1 poisons, was variously decorated (i.e., a substituted phenyl ring at 2- or 3-position, a protonable side chain at 4- or 5-position), affording a number of Top1 inhibitors with cleavage patterns common
为了寻找一种新的化学型来开发拓扑异构酶 I (Top1) 抑制剂,吡唑并 [1,5- a ] 喹唑啉核在结构上与著名的 Top1 毒物的茚并异喹啉系统前体相关,被不同地装饰(即取代的苯基2 位或 3 位的环,4 位或 5 位的可质子侧链),提供了许多具有 CPT 和 MJ-III-65 常见裂解模式的 Top1 抑制剂。SARs 数据通过先进的对接协议进行了合理化。
