Corticoid 17-alkyl carbonate 21-carboxylic and carbonic esters of the formula I ##STR1## are described in which A is CHOH and CHCl, CH.sub.2, C.dbd.O or 9(11) double bond; Y is H, F or Cl; Z is H, F or CH.sub.3 ; R(1) is aryl or hetaryl; n and m are zero or 1; R(2) is alkyl or --(CH.sub.2).sub.2 --OCH.sub.3 ; R(3) is H or methyl. They are obtained by reacting a compound of the formula II, ##STR2## in which R(5) is OH, with an activated carboxylic acid of the formula III, R(6)--CO--(O).sub.n --(X)--R(1) III. The compounds I have a very strong local and topical antiinflammatory action and exhibit a very good ratio of local to systemic antiinflammatory effects, which ratio is often markedly superior to that of analogous corticoid 17-alkyl carbonate 21-esters which do not carry any aryl or heteraryl group in the 21-ester radical.
本文介绍了公式I中的Corticoid 17-烷基
碳酸酯21-
羧酸和
碳酸酯,其中A为CHOH和CHCl,
CH2,C = O或9(11)双键; Y为H,F或Cl; Z为H,F或
CH3; R(1)为芳基或杂环基; n和m为零或1; R(2)为烷基或--( )2--O ; R(3)为H或甲基。它们是通过将公式II的化合物与公式III的活性
羧酸反应而获得的,其中R(5)为OH,R(6) - CO-(O)n-(X) -R(1)III。化合物I具有非常强的局部和局部抗炎作用,并表现出非常好的局部与全身抗炎效应比,这种比率通常明显优于不在21-酯基团中携带任何芳基或杂环基的类似的Corticoid 17-烷基
