我们之前的研究发现,4-氨基- 2h -苯并[h]铬-2- 1 (ABO)和4-氨基-7,8,9,10-四氢- 2h -苯并[h]铬-2- 1 (ATBO)类似物在体外具有显著的抗癌作用。我们的持续研究现在已经发现了一种新的简化(单环而不是三环)的细胞毒性药物,4-氨基- 2h -吡喃-2- 1 (APO)类似物。通过在吡喃酮环上加入各种取代基,我们建立了初步的构效关系(SAR)。类似物19、20、23和26-30在体外表现出显著的肿瘤细胞生长抑制活性。活性化合物27的ED50值为0.059 ~ 0.090 μM。
4-Amino-2H-benzo[h]chromen-2-one (ABO) and 4-amino-7,8,9,10-tetrahydro-2H-benzo[h]chromen-2-one (ATBO) analogs were found to be significant in vitro anticancer agents in our previous research. Our continuing study has now discovered a new simplified (monocyclic rather than tricyclic) class of cytotoxic agents, 4-amino-2H-pyran-2-one (APO) analogs. By incorporating various substituents on the pyranone ring, we have established preliminary structure-activity relationships (SAR). Analogs 19, 20, 23, and 26–30 displayed significant tumor cell growth inhibitory activity in vitro. The most active compound 27 exhibited ED50 values of 0.059–0.090 μM.
