Isolation, Characterization, and Docking Studies of (Z)-Isopropyl 7-((1R, 2R, 3R, 5S)- 2-((1E, 3Z)-3-Fluoro-4-Phenoxybuta-1, 3-Dienyl)-3,5-Dihydroxycyclopentyl) Hept-5- Enoate, an Impurity of Tafluprost

Introduction: The origin, isolation, and characterization of (Z)-isopropyl 7-((1R, 2R, 3R, 5S)-2-((1E, 3Z)-3-fluoro-4-phenoxybuta-1, 3-dienyl)-3, 5-dihydroxycyclopentyl) hept-5-enoate, an impurity found in the preparation of an anti-glaucoma agent-Tafluprost has been described in this study. Materials and Methods: Further, an enantiospecific synthesis of (Z)-isopropyl 7-((1R, 2R, 3R, 5S)-2-((1E, 3Z)- 3-fluoro-4-phenoxybuta-1, 3-dienyl)-3, 5-dihydroxycyclopentyl) hept-5-enoate has been revealed using deoxofluorination as a key transformation of the strategy. Results and Discussions: Moreover, the impurity showing anti-glaucoma properties in docking studies with respect to bimatoprost has been described. Conclusion: The extention of our work towards docking studies and the present impurity molecule showed almost the same biological activity with respect to Tafluprost.
