Exploring the Potential of Coumarin Derivatives on Serotonin Receptors 5-HT_1A and 5HT_2A.

ABSTRACT: A series of 2- and 3-methoxyphenylpiperazine derivatives in combination with a 2-hydroxypropoxy linker and coumarins containing various substituents was synthesized and evaluated for antidepressant-like activity. Microwave-assisted synthesis was used, and the structures of all compounds were confirmed by ¹H, ¹³C NMR, and HRMS spectrometry. The affinity toward the 5-HT_1A and 5-HT_2A receptors was determined using radioligand binding assays and analyzed by molecular docking studies. Among the compounds evaluated, four demonstrated high affinity for the 5-HT_1A receptor with the following Ki values: 5-(2-hydroxy-3-(4-(2-methoxyphenyl)piperazin-1-yl)propoxy)-4,7-dimethyl-2H-chromen-2-one (5) (90 nM), 6-acetyl-5-(2-hydroxy-3-(4-
