Compounds useful in the treatment of autoimmune disease are described by the followinggeneral formula (I): n = 0-2 m = 0-2 m is not necessarily equal to n; where R,R = NH, F, Cl, C-C alkoxy or phenoxygroup, but R is not necessarily equal to R; and R= H, F, Cl, NH, or NH- R- XH; where R = - (CH)p - p = 2-4 = Formula(II), Formula (III) = Formula (IV) q = 0-3 X = CH, NH, O, or S.
