High potent and selective arylpiperazine derivatives as ligands for the 5-HT1A receptor

Bioorg Med Chem Lett. 2000 May 15;10(10):1089-92. doi: 10.1016/s0960-894x(00)00165-7.

Abstract

This paper reports the synthesis and affinities on the 5-HT1A versus the alpha1A receptors of new arylpiperazinylalkylthiothienopyrimidine and thiadiazole derivatives 16-24. Arylpiperazines 16-23 show affinities values in the nanomolar range for the 5-HT1A receptor. The compound 16 is highly potent (Ki 0.26 nM, selectivity 28), the derivatives 20 and 21 are less potent, but highly selective (Ki 9.40 and 5.06 nM, selectivity 207 and 73, respectively).
