Detection of in Vitro Metabolite Formation of Leflunomide: A Fluorescence Dynamics and Electronic Structure Study.

TL;DR: The metabolic transformation of antirheumatic fluorescent drug leflunomid into its active metabolite teriflunomide through isoxazole ring opening has been monitored in vitro using steady state and time domain fluorescence spectroscopy and density functional theory to reveal slow conversion of lefl UNO to E and Z forms in aqueous medium, which becomes faster at basic pH.
Journal ArticleDOI

A novel Raman spectroscopic approach to identify polymorphism in leflunomide: a combined experimental and theoretical study

TL;DR: In this article, the presence and conversion of α to β polymorphic forms of an anti-rheumatic drug leflunomide have been studied by temperature-dependent and in situ Raman observations.
Journal ArticleDOI

Temperature dependent polymorphism of pyrazinamide: An in situ Raman and DFT study

TL;DR: The α and γ polymorphs of drug pyrazinamide have been detected with the help of temperature dependent Raman spectroscopic technique and polymorphic phase change from α→γ form of pyrazine between 145 and 146°C is suggested.
Journal Article

Monitoring the in Vitro Thiazolidine Ring Formation of Antioxidant Drug N-Acetyl-l-cysteine at Basic pH and Detection of Reaction Intermediates: A Raman Spectroscopic and Ab Initio Study

TL;DR: Correlation of the theoretically calculated results with experimental Raman spectral analysis has led to a detailed and proper understanding of this important biochemical reaction.
