Phytochemical Analysis, EarlyView.ABSTRACT Introduction Antimicrobial resistance is a global public health problem that requires the development of new bioactive compounds. In this context, metabolomic analyses can expedite the research of fungal metabolites as a valuable resource. Objectives To investigate the metabolic profiles and isolate antibacterial compounds from micromycetes ...

Synthesis of New Potentially Bioactive Bicyclic 2-Pyridones
Molecules, 2005 Three convenient methods of reduction of the nitro group of 5-nitroimidazoles and 5-nitrothiazole that bear a diethylmethylene malonate group in an ortho-like position with respect to the nitro group and cyclization of the resulting amino derivatives are

Chemical constitutions in the Colour Index™: A century of colourant classification
Coloration Technology, EarlyView.Abstract This article details how the Colour Index™ (CI) system categorises and unambiguously labels commercial dyes and pigments based upon their chemical constitutions. It outlines the current process by which colourants that are new to the market find a place within CI and acquire generic identifiers.

Effect of Substituents on the Tautomerism of Pyridone Nucleoside Analogs
European Journal of Organic Chemistry, Volume 28, Issue 14, April 7, 2025.Experimental and quantum‐chemical work shows that the predominant tautomer of 6‐fluoropyridones is the lactim, not the lactam form. This makes them analogs of cytosine, not uracil or thymine in the context of incorporation opposite complementary bases of genetic sequences. Abstract Nucleobase analogs are important tools in medicine and chemical biology,
