摘要:
The invention relates to novel 17.beta.-substituted 4-azaandrostane derivatives of general formula (I), ##STR1## wherein R means hydrogen or a C.sub.1-3 alkyl group;R.sup.1 and R.sup.2 are the same or different and stand for hydrogen or a C.sub.1-4 alkyl group with the proviso that both can mean hydrogen only in the case when n is higher than 5; orR.sup.1 and R.sup.2 together means an .alpha.,.omega.-alkylene group containing 5 to 7 carbon atoms, the terminal carbon atoms of said alkylene group being bound to the same ring carbon atom;n is 4, 5, 6 or 7; and--- bond line represents a single or double bond.Furthermore, the invention relates to pharmaceutical composition containing these compounds as well as a process for the preparation of the compounds of general formula (I).The compounds of general formula (I) exert a 5.alpha.-reductase enzyme-inhibiting effect and therefore, they are useful for treating all diseases, where the aim is to reduce the tissue dihydrotestosterone level, such as the benign prostatic hyperplasia, acne, seborrhoea, female hirsutism or androgenic alopecia.
