Method for Preparation of Apixaban

The present invention relates to a novel method for manufacturing apixaban. According to the method of the present invention, the method does not use expensive reagents or solvents, thereby being economical. In addition, there is no special condition or complicated process, and dangerous reagents or solvents are not used, thus the method is easy for mass-production industrially. Furthermore, since no toxic solvents are used in the final step of the synthesis and purification of apixaban, it is possible to manufacture a high purity apixaban with a high yield without the risk of residual solvent.COPYRIGHT KIPO 2020

Design, synthesis, and biological activity of novel tetrahydropyrazolopyridone derivatives as FXa inhibitors with potent anticoagulant activity

A series of novel tetrahydropyrazolopyridone derivatives containing 1,3,4-triazole, triazolylmethyl, and partially saturated heterocyclic moieties as P2 binding element was designed, synthesized, and evaluated in vitro for anticoagulant activity in human and rabbit plasma. All compounds showed moderate to significant potency, and compounds 15b, 15c, 20b, 20c, and 22b were further examined for their inhibitory activity against human FXa in vitro. While compounds 15c and 22b were tested for rat venous thrombosis in vivo. The most promising compound 15c, with an IC50 (FXa) value of 0.14?μM and 98% inhibition rate, warranted further investigation as an FXa inhibitor.

LACTAM-CONTAINING COMPOUNDS AND DERIVATIVES THEREOF AS FACTOR XA INHIBITORS

The present application describes lactam-containing compounds and derivatives thereof of Formula I: P4—P-M-M4??I or pharmaceutically acceptable salt forms thereof, wherein ring P, if present is a 5-7 membered carbocycle or heterocycle and ring M is a 5-7 membered carbocycle or heterocycle. Compounds of the present invention are useful as inhibitors of trypsin-like serine proteases, specifically factor Xa.
