    基于阿那曲唑模板的双重芳香酶硫酸酯酶抑制剂:合成,体外SAR,分子模型和体内活性。
    摘要:
    描述了一系列新型双重芳香酶-硫酸酯酶抑制剂(DASIs)的合成和生物学评估。假定双重抑制芳香酶和类固醇硫酸酯酶,两者都负责雌激素的生物合成,在治疗激素依赖性乳腺癌中将是有益的。这些化合物基于阿那曲唑芳香化酶抑制剂模板,该模板在维持血红素连接三唑部分对酶抑制至关重要的同时,经过修饰,使其包括苯酚氨基磺酸酯基序,即有效抑制不可逆类固醇硫酸酯酶的药效基团。通过选择性自由基溴化和取代反应以提供一系列抑制性芳香化酶药效基团,可以使合成路线适应阿那曲唑。将这些片段连接至氨基磺酸氨基酚酯部分,使用S(N)2,Heck和Mitsunobu反应与酚类前体进行反应,从中通过氨磺酰化反应完成DASI。在体外,先导化合物11对芳香化酶(IC(50)3.5 nM)具有很高的效力,与阿那曲唑(IC(50)1.5 nM)相当,而对甾族硫酸酯酶的活性却中等。然而,在体内,11出人意料地表现出有效的双重抑制作用。将化合物1

    The present invention discloses a process for the preparation of Anastrozole of the formula I in high purity and in high yield. 3,5-bis(halomethyl)toluene is prepared by reacting mesitylene with N-halosuccinimide in the presence of light or dibenzoyl peroxide or azobis isobutyronitrile as a catalyst and in a chlorinated solvent. 3,5-bis(halomethyl)toluene is cyanated with metal cyanide in the presence of a catalyst and in water, organic solvent or mixture thereof at temperature of 40 to 60° C. to obtain 2,2′-(5-methyl-1,3 phenylene)diacetonitrile which is further methylated with iodomethane in the presence of base and an organic solvent at temperature of 0 to 15° C. to obtain 2,2′-(5-methyl-1,3-phenylene)di(2-methyl-propiononitrile). The product obtained is treated with N-halosuccinimide in the presence of a catalyst and in a chlorinated solvent at temperature of 60 to 100° C. to obtain 2,2′-(5-halomethyl-1,3-phenylene)di(2-methyl propionitrile) which was further treated with potassium or sodium salt 1,2,4-triazole at temperature of 20 to 50° C. in dimethyl formamide to obtain crude 2,2′-[5-( 1 H-1,2,4-triazole-1-ylmethyl)-1,3-phenylene]di(2-methyl-propionitrile). The crude product is purified by column chromatography using a stationary phase and a mobile phase followed by recrystallization with a solvent or mixture of solvents to obtain highly pure Anastrozole.
