產(chǎn)品編號:Y3713
英文名稱:(S)-(+)-Camptothecin
CAS號:7689-03-4分析標準品,≥98%
分子式 C20H16N2O4 分子量348.35
基本信息:
密度 1.51
熔點 259-263°C
存貯條件 貯存溫度2-8℃
描述
產(chǎn)品介紹 微溶于乙醇、氯仿,難溶于水。與酸不能生成穩(wěn)定的鹽,與氫氧化鈉溶液加熱反應可生成鈉鹽而溶于水。鈉鹽水溶液黃色澄明具藍色熒光
別名 喜樹堿 ;4-乙基-4-羥基-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
生化機理
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.
應用 不可逆轉(zhuǎn)地的結(jié)合到DNA拓撲異構(gòu)酶I復合物上,影響細胞周期進程
