Discovery of Ritonavir, a Potent Inhibitor of HIV Protease with High Oral Bioavailability and Clinical Efficacy
摘要:
The structure-activity studies leading to the potent and clinically efficacious HIV protease inhibitor ritonavir are described. Beginning with the moderately potent and orally bioavailable inhibitor A-80987, systematic investigation of peripheral (P3 and P2') heterocyclic groups designed to decrease the rate of hepatic metabolism provided analogues with improved pharmacokinetic properties after oral dosing in rats. Replacement of pyridyl groups with thiazoles provided increased chemical stability toward oxidation while maintaining sufficient aqueous solubility for oral absorption, Optimization of hydrophobic interactions with the HIV protease active site produced ritonavir, with excellent in vitro potency (EC50 = 0.02 mu M) and high and sustained plasma concentrations after oral administration in four species. Details of the discovery and preclinical development of ritonavir are described.

The invention relates to new compounds of the formula I
to their use as medicaments, to methods for their therapeutic use and to pharmaceutical compositions containing them.
A novel and excellent method for preventing and/or treating diseases related to a cannabinoid type 2 receptor, based on an agonistic action on a cannabinoid type 2 receptor. It was found that a hetero ring derivative mainly having two substituents, for example, a pyrimidine-5-carboxamide derivative having a substituent amino group at the 2-position, exhibits a potent agonistic action on a cannabinoid type 2 receptor, and can be an agent for preventing and/or treating diseases related to a cannabinoid type 2 receptor such as inflammatory diseases, pain, and the like.
