A series of new benzoylquinoxaline derivatives (7-26) was synthesized and evaluated for antitumor activity against a panel of 60 human cell lines at the NCI of Bethesda. Among the compounds which have passed the preliminary screening, compound 23 exhibited the best profile and growth inhibition activity at 100 - 10 μM. The compounds were then tested towards a folate-dependent enzymes bio-library including
合成了一系列新的苯甲酰基喹喔啉衍生物(7-26),并评估了在贝塞斯达NCI对一组60种人类细胞系的抗肿瘤活性。在通过初步筛选的化合物中,化合物23在100-10μM时表现出最佳的分布和生长抑制活性。然后测试化合物对叶酸依赖性酶生物文库的影响,包括10μM的胸苷酸合酶和人二氢叶酸还原酶。大多数化合物对所有或部分测试的酶表现出中等抑制活性,可检测的抑制常数(K i)值在0.6-70μM的范围内。化合物21、23、24显示K i hDHFR和hTS均在10-38μM的范围内。
