  A series of 21-(alkylthio)acetates and 21-(methylthio)methoxides of corticosteroids were synthesized and examined for vasoconstrictive activities. The activities of seven compounds were equal to or greater than that of 9α-fluoro-11β, 21-dihydroxy-16β-methyl-17α-valeryloxy-1, 4-pregnadiene-3, 20-dione (betamethasone 17-valerate, BV). Among them, betamethasone 21-(methylthio)acetate 17-propanoate (2Ca) was found to have the most potent activity, which is superior to that of BV. A structure-activity relationship study revealed that substitution of the 21-hydroxy group of corticosteroids with the (methylthio)acetate function is a useful approach for obtaining potent activity.

  一系列含有21-（烷硫基）乙酸酯和21-（甲硫基）甲氧基的皮质类固醇被合成并测试了它们的血管收缩活性。七个化合物的活性等于或超过9α-氟-11β, 21-二羟基-16β-甲基-17α-戊酸酯-1, 4-孕二烯-3, 20-二酮（倍他米松17-戊酸酯，BV）。其中，倍他米松21-（甲硫基）乙酸酯17-丙酸酯（2Ca）显示出最强的活性，优于BV。结构-活性关系研究表明，将皮质类固醇的21-羟基替换为（甲硫基）乙酸酯功能是一种有效的方法，用以获得强大的活性。
