substituent R(4). The corresponding QSAR equation was obtained for the whole set of compounds for the antiproliferative activity, the electronic parameter sigma(R) of R(4), the molar refractivity of R(8), and the lipophilic parameters clog P and pi(linker). The most potent antiproliferative agent so far described is 40 for which an IC(50) = 0.45 microM was predicted by the QSAR equation, while its experimental
研究旨在建立定义40种双喹啉鎓化合物对胆碱激酶的抑制和抗增殖活性的构效关系。这些衍生物在喹啉鎓环的4位具有电子释放基团。发现酶促抑制作用与接头的大小密切相关,最合适的是3,3'-联苯部分。另一方面,针对HT-29癌细胞系的抗增殖活性受接头类型和取代基R(4)的影响较小。针对整个化合物的抗增殖活性,R(4)的电子参数sigma(R),R(8)的摩尔折射率以及亲脂性参数clog P和pi(连接子)获得了相应的QSAR方程。
