The compounds of formula (1), wherein n is an integer from 0 to 4; R1 is a radical selected from the group consisting of H, CH3, CH2-CH3, C(CH3)3, COOH, CONH2 and C=CH; R2, R3, R4 and R5 are radicals independently selected from the group consisting of H, F, Cl, Br, (C1-C3)-alkoxyl and (C1-C4)-alkyl; and R6 is a radical selected from the group consisting of H, F, Cl, Br, (C1-C3)-alkoxyl, (C1-C4)-alkyl, R7, CH=CH-R7 and O-CH2-R7; wherein R7 is phenyl or phenyl mono- or independently di-substituted with F, Cl, Br, (C1-C3)-alkoxyl or (C1-C4)-alkyl, exhibit a similar chemotactic index to that of amygdalin (natural product whose chemotaxis profile is similar to that of peptide T) and, consequently, are useful for treating inflammatory and/or allergic dermatophathies, such as psoriasis, and are especially much less toxic than amygdalin.
