Identification and characterization of a selective, nonpeptide follicle-stimulating hormone receptor antagonist. Arey BJ 1 , Deecher DC, Shen ES, Stevis PE, Meade EH Jr, Wrobel J, Frail DE, Lopez FJ. Author information: 1 Women 's Health Research Ins.ute and Medicinal Chemistry, Department of Chemical Sciences, .The affinity of an antagonist for its binding site Ki , i.e. its ability to bind to a receptor, will determine the duration of inhibition of agonist activity. The affinity of an antagonist can be determined experimentally using Schild regression or for compe.ive antagonists in radioligand binding stu.s using the Cheng-Prusoff .And receptor binding experiments. The extreme structural diversity of the antagonist compounds shows how receptor-based virtual screen- ing can identify diverse chemistries that comply with the structural rules of TR antagonism. Overproduction of thyroid hormone hyperthyroidism or thy- rotoxicosis is an extremely .In the stu.s described here, we report the identification and pharmacological characterization of the first known selective, small molecule antagonist of the FSHR. These stu.s provide a theoretical basis for the development of selective small molecule glycoprotein hormone receptor antagonists for potential use as novel .
