The invention relates to novel 19-thio-androstane derivatives having the general formula: ##STR1## and the 4,5-dihydro analogues thereof, wherein R.sub.1 =H, hydrocarbyl(1-4C), aralkyl(7-9C), aryl(6-9C) or acyl derived from an organic carboxylic acid having 1-18 C atoms; R.sub.2 =O, .alpha.R.sub.4 (.beta.R.sub.3) or an acetal group; R.sub.3 =a free, esterified or etherified hydroxyl group; and R.sub.4 =H or hydrocarbyl(1-4C); and wherein the broken lines indicate the optional presence of a double bond in the 1,2-position and/or 6,7-position, and to processes for obtaining same. The novel compounds possess aromatase-inhibiting properties.
本发明涉及一种新的19-
硫基雄烷衍
生物,其具有以下一般式:##STR1##以及其4,5-二氢类似物,其中R.sub.1 =H,烃基(1-4C),芳基烷基(7-9C),芳基(6-9C)或来源于具有1-18个C原子的有机
羧酸的酰基;R.sub.2 =O,.alpha.R.sub.4(.beta.R.sub.3)或
缩醛基;R.sub.3 =自由、酯化或醚化的羟基;R.sub.4 =H或烃基(1-4C);其中断裂的线表示1,2-位置和/或6,7-位置可能存在双键,并且提供了获得这些化合物的方法。这些新化合物具有抑制芳香化酶的性质。
