Chemical and Bioactive Metabolites of Humicola and Nigrospora Secondary Metabolites

Bioactive secondary metabolites from Juncaceae species

Bioactive secondary metabolites from Salix tetrasperma Roxb.

Column chromatography of the light petroleum fraction from the methanolic extract of the stem bark of Salix tetrasperma Roxb. (Salicaceae) resulted in the isolation of beta-sitosterol acetate, friedelin, 3beta-friedelinol, beta-amyrin, beta-sitosterol, beta-sitosterol-O-glucoside in addition to palmitic acid. From the dichloromethane fraction of the leaves, catechol and tremulacin were isolated...

Production of Bioactive Secondary Metabolites by Marine Vibrionaceae

Bacteria belonging to the Vibrionaceae family are widespread in the marine environment. Today, 128 species of vibrios are known. Several of them are infamous for their pathogenicity or symbiotic relationships. Despite their ability to interact with eukaryotes, the vibrios are greatly underexplored for their ability to produce bioactive secondary metabolites and studies have been limited to only...

Actinomycetes: a yet inexhaustive source of bioactive secondary metabolites

The rapid emergence of antimicrobial resistance among pathogens has led to a renewed interest to search for novel antimicrobial agents. The history of new drug discovery processes shows that novel skeletons have, in the majority of cases come from natural sources. This involves screening of microorganisms or plant extracts. They have been the source of, or inspiration for the development of che...
