  • Patent number: 5824670
    Abstract: 17-Deoxycorticoid-21-carboxylic 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 and R(2) is H or methyl. They are obtained by reacting a compound of the formula II, ##STR2## in which R(4) is OH, with an activated carboxylic acid of the formula III,R(5)-CO--X-R(1) III.The compounds I possess very strong local and topical antiinflammatory activity and exhibit a very good ratio of local to systemic antiinflammatory effect, which ratio is often clearly superior to that of structurally related corticoid 21-esters which do not carry any aryl or hetaryl group in the 21-ester residue or to that of analogous 17-deoxycorticoids having an unesterified, that is a free, 21-hydroxyl group.

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.
