Novel tri-phenyl alkane and alkene derivatives and their preparation and use
摘要:
The invention provides novel compounds of the formula:
and
wherein m is 1 or 2, R 6 and R 7 , which can be the same or different are H or an alkyl group of 1 to 4 carbon atoms, or
wherein n is 0 to 4, R 1 and R 2 , which can be the same or different are H, OH, alkoxy of 1 to 4 carbon atoms, benzyloxy or methoxymethoxy; R 3 is H, OH, halogen, alkoxy of 1 to 4 carbon atoms, benzyloxy, methoxymethoxy, 2,3-dihydroxypropoxy or
can form an N-containing three-, four-, five- or six-membered heterocyclic ring; R 4 is OH, F, Cl, Br, I, mesyloxy, tosyloxy, formyloxy, alkylcarbonyloxy of 1 to 4 carbon atoms or CH 2 R 4 is replaced by CHO; R 5 is H or OH; or R 4 and R 5 together form an -0- bridge between the carbon atoms to which they are attached, and their non-toxic pharmaceutically acceptable salts and esters and mixtures thereof. Processes for the preparation of these compounds are described, and also novel pharmaceutical compositions containing them. These compounds exhibit valuable pharmacological properties as estrogenic, anti-estrogenic, and progestanic agents. They are also effective against oestrogen-dependent tumours. Certain compounds are useful as chemical intermediates for the preparation of pharmacologically active compounds of the invention.
