The present invention relates to cyclopentanone derivatives of the formula [1A] to [1C], wherein the symbols X and Y are S, O, SO, SO2 or NH, and the symbol Z represents an aliphatic, aromatic or saturated or unsaturated heterocyclic group, [ID] in which X is S, O, SO, SO2 or NH, Y, A and B are independently selected from the group consisting of an aliphatic, aromatic, saturated or unsaturated heterocyclic group, [1E], and [1F] b-disubstituted amino ketone derivatives of the general formula wherein A, B, X, Y and Z are independently selected from an aliphatic, aromatic, or saturated unsaturated heterocyclic group. The present invention also relates to pharmaceutical compositions containing the above compounds as active ingredients. Compounds of the present invention and pharmaceutical neuron differentiation are useful. HE |
