title: Synthesis of 2-carboxy-11 beta, 17 beta-dihydroxy-17-methyl-1, 4-androstadien-3-one and related compounds.
abstract: A series of 2-carboxy-1, 4-androstadien-3-one derivatives and their alkyl esters, were prepared by high-yield syntheses. The compounds were structurally identified by physical methods. All these steroids are characterized by a marked antiglucocorticoid activity that proved long-acting in the case of the ester derivatives. 2-Carboxy-11 beta, 17 beta-dihydroxy-17-methyl-1, 4-androstadien-3-one or roxibolone, and its n-decylester or decylroxibolone, are the most promising derivatives in consideration of their pharmacological properties.
