Benzothiophene compounds, compositions, and methods for inhibiting aortal smooth muscle proliferation

Abstract

The present invention provides novel benzothiophene compounds of formula I ##STR1## wherein R is --H, --OH, --O(C.sub.1 -C.sub.4 alkyl), --O--CO--(C.sub.1 -C.sub.6 alkyl), --O--CO--Ar in which Ar is optionally substituted phenyl, or --O--SO.sub.2 --(C.sub.4 -C.sub.6 alkyl); R.sup.1 is --H, --OH, --O(C.sub.1 -C.sub.4 alkyl), --O--CO--(C.sub.1 -C.sub.6 alkyl), --O--CO--Ar in which Ar is optionally substituted phenyl, --O--SO.sub.2 --(C.sub.4 -C.sub.6 alkyl) chloro or bromo; R.sup.2 is --H or --OH; n is 2 or 3; and R.sup.3 and R.sup.4 each are independently C.sub.1 -C.sub.4 alkyl, or combine to form 1-piperidinyl, 1-pyrrolidinyl, methyl-1-pyrrolidinyl, dimethyl-1-pyrrolidinyl, 4-morpholino, or 1-hexamethyleneimino; or a pharmaceutically acceptable salt thereof, for inhibiting aortal smooth muscle proliferation.
