Graphics computer-aided receptor mapping as a predictive tool for drug design: development of potent, selective, and stereospecific ligands for the 5-HT1A receptor
摘要:
A conformational study of four 5-HT1A (serotonin) receptor ligands ((R-(-)-methiothepin, spiperone, (S)-(-)-propranolol, and buspirone) led to the definition of a pharmacophore and a three-dimensional map of the 5-HT1A antagonist recognition site. These models were used to design new compounds and successfully predict their potency, stereospecificity, and selectivity. For example, 8-[4-[(1,4-benzodioxan-2-ylmethyl)amino] butyl]-8-azaspiro[4.5]decane-7,9-dione (1, MDL 72832) has nanomolar affinity (pIC50 = 9.14) for the 5-HT1A binding site in rat frontal cortex. As predicted, the S-(-) enantiomer of 1 was more active than its R-(+) enantiomer (pIC50 = 9.21 and 7.66, respectively) and a naphthalene analogue of 1 displayed the expected improved selectivity.
