title: Synthesis, physicochemical and preliminary pharmacological properties of N-[beta-hydroxy-gamma-(N-phenylpiperazinepropyl)]-2-pyrrolidinone.
abstract: The present paper reports on the synthesis and preliminary pharmacological properties of N-[beta-hydroxy-gamma-(N-phenylpiperazinepropyl)]-2- pyrrolidinone (MG-1). MG-1 was obtained by aminolysis of 1-(beta, gamma-epoxypropyl)-2-pyrrolidinone and N-phenylpiperazine. Its structure was established by elemental and spectral analyses (IR, UV, MS, 1H, 13C, 2D H-H and 2D C-H NMR). The antiarrhythmic activity of MG-1 was investigated on mice, rats and guinea pigs, using several models of arrhythmia. MG-1 attenuated or prevented the adrenaline- and barium chloride-induced arrhythmia. MG-1 demonstrated potent local anesthetic properties and depressed the depolarization phase of the action potential of cardiac cells. These results indicate that MG-1 possesses antiarrhythmic activity.
