  Synthesis by microwave irradiation and binding properties of novel 5-HT1A receptor ligands

  摘要：

  This work reports the synthesis by microwave irradiation and the binding tests on the 5-HT1A, 5-HT2A and 5-HT2C receptors of new substituted piperazines in order to identify selective ligands for 5-HT1A 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-HT1A 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-HT1A over all the considered receptors was the 3-{4-[4-(1,2,3,4-tetrahydronaplithyl)-1-piperazinyl]butan}-benzotriazinone (-)29 (5-HT1A K-i = 36 nM, other receptors not active).

  A series of novel 1,2,3-4-benzoyltriazole and saccharine derivatives were designed and synthesized by microwave heating. They were evaluated on a battery of receptors, including serotonin 5-HT(1A,) 5-HT(2A) and 5-HT(2C), and the most interesting compounds were further evaluated on dopaminergic D(1), D(2) and adrenergic alpha(1), alpha(2) receptors.
