We prepared analogs of potent thiazolidinone-based follicle-stimulating hormone (FSH) agonists 1, that is, 3 that contained an additional 5-alkyl substituent. This extra substituent was added to reduce synthetic problems that arose during preparation of analogs of 1. These compounds (3) were evaluated in a Chinese hamster ovary (CHO) cell line that expressed recombinant human FSH receptor (FSHR) and a luciferase reporter gene ...
