Abstract: A pharmaceutical compound of the formula in which R1 and R2 are each hydrogen, halo, cyano or methyl, the dotted line represents an optional double bond, where R4 and R5 are each hydrogen, C1-6 alkyl, cyclopropyl or cyclopropyl-C1-6 alkyl, n is 0 or 1, and R3 is —SR6, —SOR6, —SO2R6, —COR6, —CH2OH or —CONHR7, where R6 is C1-6 alkyl and R7 is hydrogen or C1-6 alkyl; provided that when one of R1 and R2 is hydrogen and the other is fluoro, R4 and R5 are each hydrogen or C1-6 alkyl, and n is 0, then R3 is not —COR6 or —CONHR7; and salts thereof.
