Butyrophenone analogues in the carbazole series as potential atypical antipsychotics: synthesis and determination of affinities at D2, 5-HT2A, 5-HT2B and 5-HT2C receptors
摘要:
We describe practical and efficient routes for synthesis of 2-aminomethyl-1,2,3,9-tetrahydro-4H-carbazol-4-ones using the Fischer indole synthesis or palladium-catalysed cyclization methodologies, as well as their affinities for D-2, 5-HT2A and 5-HT2C receptors, and their activity at the 5-HT2B receptor. The most active compounds, 4b (QF 2003B) and 4c (QF 2004B), with a pK(i) (5-HT2A/D-2) ratio of 1.28 show a potential antipsychotic profile according to Meltzer's classification.

A series of 8 new tetrahydroquinazolinone derivatives was synthesized and evaluated for binding affinity to D-2 and 5-HT2A human receptors; in addition, some properties related to blood-brain barrier penetration were calculated. From the results of these assays, three compounds were selected for further binding tests on D-1, D-3, and 5-HT2C human receptors, which are thought to be involved in schizophrenia. From these data, compound 19b emerged as the most promising candidate based on its good binding affinities for D-1, D-2, and D-3 receptors, high affinity for 5-HT2A, low affinity for 5-HT2C receptors, and a Meltzer's ratio characteristic of an atypical antipsychotic profile.

We have developed a facile and efficient synthesis of new conformationally restricted butyrophenones in the indole and quinoline series via palladium-catalyzed oxidation of hydroxyenaminones, and subsequent cyclization followed by spontaneous arornatization.
