Zusammenfassung:	6-Substituted 10 beta -alkynylestrene derivatives of formula (I): wherein X is hydrogen, C1-C4 alkyl or halogen; n is zero, 1 or 2; Y is an oxo group or a methylene group; the symbol @ indicates a single bond or a double bond; R1 is halogen, azido or a group wherein each of R3 and R4 is, independently, hydrogen or C1-C4 alkyl, or R1 may be divalent and is a C1-C6 alkylidene group; and R2 is hydrogen or, when R1 is halogen, R2 may also be the same halogen as R1, and the pharmaceutically acceptable salts thereof; are aromatase inhibitors and can be used, e.g., in the treatment of hormone-dependent tumors and prostatic hyperplasia.
