ABSTRACT:
A 1,2-di-substituted benzene-carboxamide derivative or a salt thereof expressed by the following Formula (I); ##STR1## wherein each of A and B is R.sup.1 or --(CH.sub.2)n-NR.sup.2 R.sup.3, wherein when A is R.sup.1, B is --(CH.sub.2)n-NR.sup.2 R.sup.3 and when A is --(CH.sub.2)n-NR.sup.2 R.sup.3, B is R.sup.1 ; Z is --O--, --OCO--, --OCONR.sup.6 -- or --NR.sup.6 --; R.sup.1 is a hydrocarbon group of C.sub.10-30 ; R.sup.2 and R.sup.3 individually represent a hydrogen atom, a lower alkyl group, a phenyl group or a benzyl group, or together represent a heterocyclic ring having 3-7 members; when A is --(CH.sub.2)n-NR.sup.2 R.sup.3, R.sup.2 may be a hydrogen atom, a lower alkyl group, a phenyl group or a benzyl group, and R.sup.3 and R.sup.5 together may represent a heterocyclic ring of 6 or 7 members including two nitrogen atoms; when --Z--B is --OCONR.sup.6 --(CH.sub.2)n-NR.sup.2 R.sup.3 or --NR.sup.6 --(CH.sub.2)n-NR.sup.2 R.sup.3, R.sup.2 may be a hydrogen atom, a lower alkyl group, a phenyl group or a benzyl group, and R.sup.3 and R.sup.6 together may represent a heterocyclic ring of 6 or 7 members including two nitrogen atoms; R.sup.4 is selected from the group consisting of a halogen atom, a lower alkyl group, a lower acyl group, a nitro group, a cyano group, a lower alkoxycarbonyl group, a carbamoyl group, a lower alkylcarbamoyl group, a lower alkylamino group, a lower acylamino group, a lower alkoxy group and a lower acyloxy group; R.sup.5 is a hydrogen atom, a lower alkyl group, a lower acyl group or a lower alkylcarbamoyl group, or when A is --(CH.sub.2)n-NR.sup.2 R.sup.3, R.sup.5 and R.sup.3 together may represent a heterocyclic ring of 6 or 7 members including two nitrogen atoms; R.sup.6 is a hydrogen atom, a lower alkyl group, a lower acyl group or a lower alkylcarbamoyl group, or when --Z--B is --OCONR.sup.6 --(CH.sub.2)n-NR.sup.2 R.sup.3 or --NR.sup.6 --(CH.sub.2)n-NR.sup.2 R.sup.3, R.sup.6 and R.sup.3 together may represent a heterocyclic ring of 6 or 7 members including two nitrogen atoms; l is an integer of 0-2; and n is an integer of 0-5. The 1,2-di-substituted benzene-carboxamide derivative or the salt thereof has excellent hair growth and regrowth promoting effects, which are useful for care, improvement or prevention of hair loss in mammals and, in particular, in humans.
