Novel benzene derivatives are provided of the general formula (I): <CHEM> [wherein R<1> represents an amino group, a substituted amino group, a protected amino group, or a nitro group; R<2> represents an amino group, a substituted amino group, a protected amino group, a hydroxy group, a substituted hydroxy group, or a protected hydroxy group; R<3> represents an amino group, a substituted amino, a heterocyclyl group having a ring nitrogen atom as the point of binding, or a substituted heterocyclyl group having a ring nitrogen atom as the point of binding; m is 0 to 2; n is 0 to 6; with the proviso that when m is 0, then n represents an integer from 2 to 6] and salts thereof. Compounds of formula (I) except those wherein R<1> is a nitro group have activity in promoting production of nerve growth factor. Compounds of formula (I) wherein R<1> is a nitro group are intermediates for compounds of formula (I) wherein R<1> is an amino group. |
