Synthesis by microwave irradiation and binding properties of novel 5-HT(1A) receptor ligands.

Abstract：

:This work reports the synthesis by microwave irradiation and the binding tests on the 5-HT(1A), 5-HT(2A) and 5-HT(2C) receptors of new substituted piperazines in order to identify selective ligands for 5-HT(1A) subtype receptor. Conventional heating and microwave irradiation of the reactions was compared. Synthesis by microwave irradiation gave the desired compounds in better yields than those obtained by conventional heating. The overall times for the syntheses were considerably reduced. Some resulting active compounds (29 and 39) were characterised by a good selectivity profile for the 5-HT(1A) subtype receptor. The more active compounds were selected and further evaluated for their binding affinities on D(1), D(2) dopaminergic and alpha(1), alpha(2) adrenergic receptors. The compound with higher affinity and selectivity for the 5-HT(1A) over all the considered receptors was the 3-[4-[4-(1,2,3,4-tetrahydronaphthyl)-1-piperazinyl]butan]-benzotriazinone (-)29 (5-HT(1A) K(i)=36 nM, other receptors not active).
