due to a change in the rate-determining step upon changing the acylsubstituent X, but due to resonance demand of the pi-electron donor substituent on the acyl moiety. The magnitude of the rho(X) and beta(nuc) values increases with increasing the basicity of amines and with increasing the electron-withdrawing ability of the acylsubstituent X, respectively, while that of the r values decreases with increasing

The binding of a series of phenylpiperazines (3) and benzoylpiperazines (4) to central serotonin (5-HT) sites was investigated. Several derivatives of 3 displayed nanomolar affinities for 5-HT1 sites, whereas derivatives of 4 were essentially inactive both at 5-HT1 and 5-HT2 sites. 1-(2-Methoxyphenyl)piperazine (2-MPP, 3a) was found to possess an affinity (Ki = 35 nM) for 5-HT1 sites comparable to
