INTRODUCTION: The origin, synthesis, characterization and docking studies of (Z)-7-((1R,2R,3R,5S)-3,5-dihydroxy-2-((R,1E,4E)-3-hydroxy-5-phenylpenta-1,4-dien-1-yl)cyclopentyl)-N-ethylhept-5-enamide, an impurity generated in the preparation of an anti-glaucoma agent-Bimatoprost has been described. METHODS: This impurity was controlled by employing 30% Pd/C, and the impurity level was brought to the permissible level, i.e., 0.03% (ICH guidelines) in the final drug preparation of Bimatoprost. RESULTS: Finally, induced-fit docking calculations were performed to theoretically evaluate the binding efficiencies of these inhibitors in the crystal structure of Prostaglandin F syn-thase (PGFS). CONCLUSION: There are negligible differences in RMSD and docking scores between the two ligands, which amount to only 0.18 Å and 0.313 kcal/mol, respectively. These findings strongly indicate that both ligands are likely to exhibit similar biological functions and effi-ciencies.
