A 1,2-di-substituted piperidine derivative or a salt thereof expressed by the following Formula (I):
wherein one of A and B is a hydrocarbon group of C1-30 expressed by R1 and the other is -(CH2)n-NR2R3; Y is -CO-, -CONR5- or -COO-; Z is -O-, -OCO-, -OCONR6- or -NR6-; R2 and R3 individually represent a hydrogen a lower alkyl, a phenyl or a benzyl group, or together represent a heterocycle having 3-7 members; -NR5-(CH2)n-NR2R3 and -NR6-(CH2)n-NR2R3 of -(Y)1-A and -Z-B may be the following Group W:
wherein ring E is a heterocycle of 6 or 7 members including two nitrogen atoms and R2 is a hydrogen, a lower alkyl, a phenyl or a benzyl group; R4 is a hydrogen, a halogen, a lower alkyl, a lower acyl, a nitro, a cyano, a lower alkoxycarbonyl, a carbamoyl, a lower alkylcarbamoyl, a lower alkylamino, a lower acylamino, a lower alkoxy or a lower acyloxy group; each of R5 and R6 is a hydrogen, a lower alkyl, a lower acyl, a lower alkylcarbamoyl group, or a part of said ring E; l is 0 or 1; m is an integer of 2-5; and n is an integer of 0-5. The 1,2-di-substituted piperidine 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 human.
