摘要:
A compound of the formula wherein R is hydrogen or hydroxy, each R1 is ethyl, propyl, butyl, isopropyl or t-butyl, X is ═CH2, or when R is hydroxy, X is hydrogen or ═CH2, and A is —C≡C—, or —CH2—CH2—. These compounds are useful for the treatment of hyperproliferative disorders, skin diseases, and sebaceous gland diseases.
摘要:
The invention relates to a compound of the formula ##STR1## wherein A is ##STR2## Et is ethyl, and R is hydroxy and R.sup.1 is hydrogen or .dbd.CH.sub.2 or R is hydrogen or fluoro and R.sup.1 is .dbd.CH.sub.2. Compounds of formula I stimulate HL-60 cell differentiation. Accordingly, the compounds of formula I are useful as agents for the treatment of neoplastic diseases, such as leukemia.
