Introduction: Many diseases associated with oxidative stress threaten human health, exaggerated by antibiotic-resistant bacterial infections due to the increasing use of antibiotics. The aim present study was evaluate antioxidant and antimicrobial activities a nanoemulsion prepared from Artemisia vulgaris essential oil (EO). Methods: Poly (lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) wer...

Penicillin G was found to inhibit the formation of the d-alanyl-l-alanine cross-linkage in intact cells of Micrococcus luteus. This reaction was approximately 50-fold less susceptible to penicillin than the formation of the d-alanyl-l-lysine cross-linkage in the same organism. The presence of two penicillin-susceptible transpeptidation reactions that function in the incorporation of peptidoglyc...

An easy, effective and eco-friendly one-pot process for the preparation of 4H-pyran compounds has been established by using a catalytic amount reduced graphene oxide functionalized with diethylenetriamine (rGO-DETA) in water under mild conditions. The catalyst was very this reaction provided desired products 1a–t good to high yields (87%–97%) short times. Moreover, rGO-DETA composite could be r...
