Abstract

The invention relates to benzocyclophosphamide phenate derivatives or pharmaceutically acceptable salts (I) thereof. The benzocyclophosphamide phenate derivatives or pharmaceutically acceptable salts thereof comprise stereoisomerides or tautomers. In the formula (I), R is 4-hydroxyphenyl, 4-methoxyphenyl, 4-acetoxy-phenyl, 3, 4-dihydroxyphenyl, 3, 4, 5-trihydroxyphenyl, 3, 4-dimethoxyphenyl, 3, 4, 5-trimethoxyphenyl, 3, 4-dihydroxy styryl, 3-methoxy-4-hydroxy styryl, 3, 4-dimethoxy styryl, 3, 4-diacetoxy styryl and 3-methoxy-4-acetoxy styryl. The benzocyclophosphamide phenate derivatives disclosed by the invention have significant anti-cancer effect, can effectively prolong the survival time of mice loaded with HL60, have better effects than the cyclophosphamide and have the obvious inhibitory action against the angiogenesis of a chorioallantoic membrane (CAM). Thus, the benzocyclophosphamide phenate derivatives disclosed by the invention can be applied to preparation of anti-tumor medicaments. The invention discloses the preparation method of the benzocyclophosphamide phenate derivatives.

Description

technical field [0001] The invention relates to a phenolic acid benzocyclophosphamide derivative, a preparation method thereof and an application as an anticancer drug. Background technique [0002] Cyclophosphamide is a bifunctional alkylation and cell cycle non-specific drug, which has a broad anti-tumor spectrum and is widely used in clinic. But its disadvantage is bladder toxicity. In order to reduce its toxic and side effects, chemists at home and abroad have modified its structure and synthesized many cyclic or non-cyclic cyclophosphamide analogues, hoping to find a class of compounds with strong effects and low toxicity. It has been reported in the literature that benzocyclophosphamide analogs have certain effects on rat L1210 lymphoid leukemia (Ludeman, Susan M, Zon, Gerald. Journal of Medicinal Chemistry, 1975,18(12):1251), 7-nitrobenzene Cyclophosphamide analogs can improve drug-selective toxicity in gene-activated prodrug therapy (GDEPT) (Zhuorong Li, Jiye Han, ...
