Apixaban, an oral, direct and highly selective factor Xa inhibitor: in vitro, antithrombotic and antihemostatic studies
Summary.  Background: Apixaban is an oral, direct and highly selective factor Xa (FXa) inhibitor in late‐stage clinical development for the prevention and treatment of thromboembolic diseases.… Expand
Discovery of 1-(4-methoxyphenyl)-7-oxo-6-(4-(2-oxopiperidin-1-yl)phenyl)-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine-3-carboxamide (apixaban, BMS-562247), a highly potent, selective, efficacious,…
Efforts to identify a suitable follow-on compound to razaxaban (compound 4) focused on modification of the carboxamido linker to eliminate potential in vivo hydrolysis to a primary aniline.… Expand
Rational design of potent, bioavailable, nonpeptide cyclic ureas as HIV protease inhibitors.
Mechanistic information and structure-based design methods have been used to design a series of nonpeptide cyclic ureas that are potent inhibitors of human immunodeficiency virus (HIV) protease and… Expand
Discovery of 1-[3-(aminomethyl)phenyl]-N-3-fluoro-2'-(methylsulfonyl)-[1,1'-biphenyl]-4-yl]-3-(trifluoromethyl)-1H-pyrazole-5-carboxamide (DPC423), a highly potent, selective, and orally bioavailable…
Factor Xa (fXa) plays a critical role in the coagulation cascade, serving as the point of convergence of the intrinsic and extrinsic pathways. Together with nonenzymatic cofactor Va and Ca2+ on the… Expand
Cyclic HIV protease inhibitors: synthesis, conformational analysis, P2/P2' structure-activity relationship, and molecular recognition of cyclic ureas.

High-resolution X-ray structures of the complexes of HIV-1 protease (HIV-1PR) with peptidomimetic inhibitors reveal the presence of a structural water molecule which is hydrogen bonded to both the… Expand
Preclinical Pharmacokinetic and Metabolism of Apixaban, a Potent and Selective Factor Xa Inhibitor.
Apixaban is a potent, orally available, highly selective, and reversible factor Xa inhibitor, and currently under development for prevention and treatment of thrombosis. The preclinical… Expand
Three‐dimensional solution structure of the HIV‐1 protease complexed with DMP323, a novel cyclic urea‐type inhibitor, determined by nuclear magnetic resonance spectroscopy
The three‐dimensional solution structure of the HIV‐1 protease homodimer, MW 22.2 kDa, complexed to a potent, cyclic urea‐based inhibitor, DMP323, is reported. This is the first solution structure of… Expand
Nonpeptide cyclic cyanoguanidines as HIV-1 protease inhibitors: synthesis, structure-activity relationships, and X-ray crystal structure studies.
Comparison of the high-resolution X-ray structures of the native HIV-1 protease and its complexes with the inhibitors suggested that the enzyme flaps are flexible. The movement at the tip of the… Expand
New Aryl/Heteroaryl C—N Bond Cross-Coupling Reactions via Arylboronic Acid/Cupric Acetate Arylation.
Improved cyclic urea inhibitors of the HIV-1 protease: synthesis, potency, resistance profile, human pharmacokinetics and X-ray crystal structure of DMP 450.
BACKGROUND Effective HIV protease inhibitors must combine potency towards wild-type and mutant variants of HIV with oral bioavailability such that drug levels in relevant tissues continuously exceed… Expand
