Synthesis and evaluation of new coumarin derivatives as potential atypical antipsychotics
摘要:
In this paper, we report the synthesis of novel, potential antipsychotic coumarin derivatives combining potent dopamine D-2, D-3 and serotonin 5-HT1A 5-HT(2)A receptors properties. We describe the structure activity relationship that leads us to the promising derivative: 7-(4-(4-(6-fluorobenzo[d]isoxazol-3-yl) piperidin-1-yl)butoxy)-6-methyl-2,3-dihydrocyclopenta[c]chromen-4(1H)-one 27. The unique pharmacological features of compound 27 are a high affinity for dopamine D-2, D-3 and serotonin 5-HT1A, 5-HT2A receptors, together with a low affinity for H-1 receptor (to reduce the risk of obesity under chronic treatment). In animal models, compound 27 inhibited apomorphine-induced climbing and MK-801-induced hyperactivity without observable catalepsy at the highest dose tested. In particular, compound 27 was more potent than clozapine. (C) 2014 Elsevier Masson SAS. All rights reserved.
