- Modified coumarins. 11. Synthesis and biological activity of mannich bases of substituted 2,3-dihydrocyclopenta[c]chromen-4-ones
-
Mannich bases containing the dialkylaminomethyl group in the 6- and 8-positions of 2,3-dihydrocyclopenta[c]chromen-4-ones were prepared by condensation of 7- and 9-hydroxy-2,3-dihydrocyclopenta[c]chromen-4-ones with substituted 1,1-diaminomethanes. The effects of 8-chloro-7-hydroxy-6-(l- pyrrolidinylmethyl)-2,3-dihydrocyclopenta[c]chromen-4-one and 8-chloro-7-hydroxy-6-(morpholinomethyl)-2,3-dihydrocyclopenta[c]chromen-4-one on the central and peripheral nervous system were defined and enable the presence of tranquilizing and neuroleptic properties to be predicted.

- Synthesis and evaluation of new coumarin derivatives as potential atypical antipsychotics
-
In this paper, we report the synthesis of novel, potential antipsychotic coumarin derivatives combining potent dopamine D2, D3 and serotonin 5-HT1A, 5-HT2A 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 D2, D3 and serotonin 5-HT1A, 5-HT2A receptors, together with a low affinity for H1 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.
