Alkylenediamine derivatives.

摘要

Novel alkylenediamine derivative having the formula (I): <CHEM> wherein A is a group having the formula (II): R<1>(CH2)m-CH(R<2>)-(CH2)n- (II) (wherein R<1> is an aliphatic hydrocarbon group, an alicyclic group, an aryl group, or an aralkyl group; R<2> is an aliphatic hydrocarbon group, en alkoxy group, an aliphatic hydrocarbon group containing an ester or ether bonding, or an aryloxy group; and each of m and n is an integer of 0 to 2, provided that m + n does not exceed 3) and B is hoydrogen, or A is a group having the formula (III): R<3>-(CH2)k- (III) (wherein R<3> has the same meaning as that of R<1> and k is an integer of 0 to 3) and B is a group repesenting by the formula (IV): R<4>- (IV) wherein R<4> has almost the same meaning as that of R<2>, p is an integer of 2 to 6, and q is an integer of 4 to 7. These compounds are useful as glutamate blockers.
