The present invention relates to novel 21-alkylated steroids of the pregnane series having the formula:
wherein R1 = alkyl (1-4 C); R2 = carboxyacyl (1-18 C); X = H, F or Cl; Y = O, H(OH), H(lower acyloxy), H(F) or H(CI) with the proviso that Y is not H(F) when X is F; and the dotted line indicates the optional presence of a double bond, to processes for their preparation and to pharmaceutical compositions containing same.
The novel compounds possess strong anti-inflammatory properties, when applied locally and cause little or no systemic, thymolytic, adrenolytic and salt-retaining effects.
本发明涉及具有以下式子的新型孕烷系列 21-烷基类
固醇:
其中 R1 = 烷基(1-4 C);R2 = 羧酰基(1-18 C);X = H、F 或 Cl;Y = O、H(OH)、H(低级酰氧基)、H(F)或 H(CI),但当 X 为 F 时,Y 不是 H(F);虚线表示任选存在的双键。
这些新型化合物在局部使用时具有很强的抗炎特性,对全身、胸腺溶解、肾上腺溶解和盐保留作用很小或没有。
