Abstract
Coumarin-benzothiazole hybrids are antitumor agents based on their antioxidant and α-glucosidase inhibitory activities. Compounds 5a–c were selected by National Cancer Institute (NCI), USA, to be screened for antitumor activity at a single dose (10 μm) against a panel of 60 cancer cell lines. The most active compound 5c was further screened at a five-dose level by NCI. Compound 5c displays half maximal growth inhibition (GI50) values of 0.24 and 0.33 μm against central nervous system (CNS) cancer (SNB-75) and ovarian cancer (OVCAR-4) cell lines, respectively. Compounds 5a–c were also screened for their antioxidant and α-glucosidase inhibitory activities.
摘要:香豆素-苯并噻唑杂化物是一种抗肿瘤剂,基于它们的抗氧化和α-葡萄糖苷酶抑制活性。美国国家癌症研究所(NCI)选择化合物5a-c在单剂量(10 μm)下对60种癌细胞系进行抗肿瘤活性筛选。最活跃的化合物5c被NCI进一步在五个剂量水平下进行筛选。化合物5c对中枢神经系统(SNB-75)癌细胞系和卵巢癌(OVCAR-4)细胞系的半数生长抑制(GI50)值分别为0.24和0.33 μm。化合物5a-c也被筛选其抗氧化和α-葡萄糖苷酶抑制活性。
