BAY-298 is an orally active and selective luteinizing hormone receptor (LH-R) antagonist with IC50s of 96 nM, 23 nM and 78 nM for hLH (human LH) and rLH (rat LH) and cLH (cynomolgus monkey LH), respectively. BAY-298 can reduce sex hormone levels[1].
BAY-298 (oral; 4.5-72 mg/kg/day; for 8 days) dosedependently loweres serum estradiol levels in proestrus[1]. BAY-298 (iv of 0.5 mg/kg or po of 2 mg/kg) has t1/2s of 31 hours and 33 hours for iv and po. And the Cmaxs are 0.28 kg/L and 0.066 kg/L for iv and po[1].

Discovery of BAY-298 and BAY-899: Tetrahydro-1,6-naphthyridine-Based, Potent, and Selective Antagonists of the Luteinizing Hormone Receptor Which Reduce Sex Hormone Levels in Vivo
J Med Chem 2019 Nov 27;62(22):10321-10341.PMID:31670515DOI:10.1021/acs.jmedchem.9b01382
The human luteinizing hormone receptor (hLH-R) is a member of the glycoprotein hormone family of G-protein-coupled receptors (GPCRs), activated by luteinizing hormone (hLH) and essentially involved in the regulation of sex hormone production. Thus, hLH-R represents a valid target for the treatment of sex hormone-dependent cancers and diseases (polycystic ovary syndrome, uterine fibroids, endometriosis) as well as contraception. Screening of the Bayer compound library led to the discovery of tetrahydrothienopyridine derivatives as novel, small-molecule (SMOL) hLH-R inhibitors and to the development of BAY-298, the first nanomolar hLH-R antagonist reducing sex hormone levels in vivo. Further optimization of physicochemical, pharmacokinetic, and safety parameters led to the identification of BAY-899 with an improved in vitro profile and proven efficacy in vivo. BAY-298 and BAY-899 serve as valuable tool compounds to study hLH-R signaling in vitro and to interfere with the production of sex hormones in vivo.
