分子式 C20H16N2O4 分子量348.35
基本信息:
密度 1.51
熔点 259-263°C
存贮条件 贮存温度2-8℃
描述
产品介绍 微溶于乙醇、氯仿,难溶于水。与酸不能生成稳定的盐,与氢氧化钠溶液加热反应可生成钠盐而溶于水。钠盐水溶液黄色澄明具蓝色荧光
别名 喜树碱 ;4-乙基-4-羟基-1H-吡喃[3',4':6,7]氮茚[1,2]喹啉-3,14(4H,12H)-二酮;4-Ethyl-4-hydroxy-1H-pyrano-[3',4':6,7]indolizino[1,2-b]quinoline-3,14(4H,12H)-dione
生化机理
Camptothecin (CPT), a cytotoxic quinoline alkaloid, is a potent DNA enzyme topoisomerase I (topo I) inhibitor with an IC50 and IC70 of 50 nM and 0.225 μM for breast cancer cell line MDA-MB-231. It has recently been undergoing phase I clinical trials. In 3D fluorescence spectra, Camptothecin presented 3 fluorescence peaks with excitation wavelengths lambdaex of 215, 255 and 365 nm, separately. Camptothecin shows high activity against various tumor cells.
应用 不可逆转地的结合到DNA拓扑异构酶I复合物上,影响细胞周期进程
