  Lead Optimization and Avoidance of Reactive Metabolite Leading to PCO371, a Potent, Selective, and Orally Available Human Parathyroid Hormone Receptor 1 (hPTHR1) Agonist

  摘要：

  We have previously shown that the oral administration of the small molecule hPTHR1 agonist PCO371 and its lead compound, 1 (CH5447240) results in PTH-like calcemic and hypophostemic activity in thyroparathyroidectomized rats. However, 1 was converted to a reactive metabolite in a human liver microsome assay. In this article, we report on the modification path that led to an enhancement of PTHR1 agonistic activity and reduction in the formation of a reactive metabolite to result in a potent, selective, and orally active PTHR1 agonist 1-(3,5-dimethyl-4-(2-((4-oxo-2-(4-(trifluoromethoxy)phenyl)-1,3,8-triazaspiro [4.5] dec-1-en-8-yl)sulfonyl) - ethyl)phenyl)-5,5-dimethylimidazolidine-2,4-dione (PCO371, 16c). This compound is currently being evaluated in a phase 1 clinical study for the treatment of hypoparathyroidism.

  Development of a Novel Human Parathyroid Hormone Receptor 1 (hPTHR1) Agonist (CH5447240), a Potent and Orally Available Small Molecule for Treatment of Hypoparathyroidism

  摘要：

  During the course of derivatization of HTS hit 4a, we have identified a novel small-molecule hPTHRl agonist, l-(3,5-dimethyl-4-(2-((2-((lR,4R)-4-methylcyclohexyl)-4-oxo-l,3,8-triazaspiro[4.5]dec-l-en-8-yl)sulfonyl)ethyl)-phenyl)-l-methylurea (CH5447240, 141). Compound 141 exhibited a potent in vitro hPTHRl agonist effect with EC20 of 3.0 mu M and EC50 of 12 mu M and showed excellent physicochemical properties, such as high solubility in fasted state simulated intestinal fluid and good metabolic stability in human liver microsomes. Importantly, 141 showed 55% oral bioavailability and a significantly elevated serum calcium level in hypocalcemic model rats.
