Synthesis, Biological Evaluation and Molecular Docking of Deferasirox and Substituted 1,2,4‐Triazole Derivatives as Novel Potent Urease Inhibitors: Proposing Repositioning Candidate
docking studies were performed to delineate possible binding modes of the compounds with the enzyme, urease. Docking analysis suggests that the synthesized compounds were anchored well in the catalytic site and extending to the entrance of binding pocket and thus restrict the mobility of the flap by interacting with its crucial amino acid residues, CME592 and His593. The overall results of urease inhibition

The present invention relates to processes for the preparation of deferasirox, an oral iron chelator developed to treat iron overload due to e.g. multiple blood transfusions. The present invention further provides novel deferasirox pseudopolymorphs and a novel amorphous form of deferasirox, processes for their preparation, as well as pharmaceutical compositions comprising same, and use thereof in treating iron overload.
Present disclosure discloses the commercially viable process for the preparation of Deferasirox and its polymorph with. Disclosed process involves the preparation of Deferasirox via metal salt of the corresponding intermediate and deferasirox metal salt.
