2-phenylindoles as antiestrogenic pharmaceutical agents

Abstract

Novel 2-phenyl indoles are disclosed of general formula (I), wherein: R.sup.1 represents one of the rests --(CH.sub.2).sub.n --S(O).sub.m --R.sup.4, --(CH.sub.2).sub.n --NR.sup.6 --SO.sub.2 --R.sup.4, (a), and n' being integers between 4 and 12 and m and m' are 0, 1 or 2; X represents a methylene group, an imino group .dbd.NR.sup.6, or an oxygen or sulphur atom; R.sup.2 and R.sup.3 independently of one another represent a hydrogen atom, a C.sub.1 -C.sub.10 alkyl group, a benzyl, alkanoyl or alkanoyloxy, or carbarnoyl rest of formula --C(O)R.sup.5 or --C(O)NR.sup.6 R.sup.7 or a tetrahydropyranyl group; R.sup.4 represents a hydrogen atom, a C.sub.1 -C.sub.10 alkyl, a completely or partially fluorinated alkyl group --(CH.sub.2).sub.o --(CF.sub.2).sub.p CF.sub.3, o and p being independently of one another integers between 0 and 6, an (alkyl)amino or (alkyl)carbamoyl group of formula (CH.sub.2).sub.q --Y--NR.sup.8 R.sup.9, q being an integer between 0 and 6 and Y representing a direct bond, a methylene or carbamoyl group (a condition being that q cannot be 0 when Y is a carbonyl group and m is 2), an aryl, aralkyl or heteroaryl group; R.sup.5 represents a C.sub.1 -C.sub.10 alkyl group or a C.sub.1 -C.sub.10 alkoxy group, a phenyl or benzyl group; R.sup.6, R.sup.7, R.sup.8 and R.sup.9 independently of one another represent a hydrogen atom, a C.sub.1 -C.sub.10 alkyl group, or a benzyl group; and R.sup.10 represents a methyl group and R.sup.11 represents a hydrogen atom, or R.sup.10 and R.sup.11 both represent a di-, tri- or tetramethylene bridge which can also have a C--C double bond at any location in the bridge. These novel compounds have strong and selective anti-oestrogen properties and are suitable for use in particular in the treatment of oestrogen-related diseases.
