dc.description.abstract | Thesis entitled ?SYNTHESIS AND CHARACTERIZATION OF SOME ACTIVE PHARMACEUTICAL INDOLE DERIVATIVES AND THEIR ANALOGS? has been presented as five chapters.Chapter-1 deals with the general introduction and biological importance of indole derivatives and fused indole derivatives. Also presents, a brief introduction to process development, importance of impurity profile (Related substances) and polymorphic studies in the process development. Chapter-2 comprises process development of zafirlukast, an anti-asthma drug, preparation of stable amorphous and new acetonitrile solvate polymorph. Chapter-3 deals with a complete impurity profile of zafirlukast including identification, synthesis, characterization and root cause of their formation. Chapter-4 explains the synthesis and characterization of new zafirlukast related analogs. Chapter-5 presents an alternative synthesis of tadalafil from D-tryptophan and sarcosine ethyl ester. Described the impurity profile of two commercial viable schemes with the identification, synthesis, characterization and root cause of their formation.Chapter-1: Introduction to process development of APIs and a brief review on indole and fused indole derivatives In this chapter introduction and biological importance of indole derivatives and fused indole derivatives were described. Also, a brief introduction to the process development, importance of impurity profile and polymorphic studies in the process development was presented.Chapter-2: An improved process for the preparation of Zafirlukast-an anti asthma drug Zafirlukast (1) is a selective and competitive oral leukotriene receptor antagonist (LTRA) marketed under the brand name accolate.Figure 1: Zafirlukast 1 Explains the improved synthesis for zafirlukast from 3-methoxy-4-methyl benzoicacid 2 (scheme 1). Esterification of acid 2 in the presence of thionyl chloride in methanol produced ester 3, which was subjected to benzylic bromination under DBDMH and AIBN in cyclohexane to provide bromo derivative. | en_US |
