Employing a highly efficient total synthesis approach, we synthesized and evaluated for antibacterial activity diverse and novel pentacycline analogs with systematic variations at C7, C8, C9, and C10. Certain substitution groups, as well as substitution patterns at various positions, were found to be preferred for increased antibacterial activity. A number of pentacycline analogs displayed pote...
Abstract Background: By increasing resistance of pathogenic bacteria to antibiotics, many attempts have been made by the researchers to find new compounds as a substitute for non-effective antibiotics. The aim of this research is a comparative study of antibacterial properties of four species on standard strains of Escherichiacoli, Shigellaflexneri, Klebsiella pneumonia, Candida and Candida alb...
A novel series of biscoumarin (1-4) and dihydropyran (5-13) derivatives were synthesized via a one-pot multicomponent condensation reaction and evaluated for antibacterial and antitumor activity in vitro. The X-ray crystal structure analysis of four representative compounds, 3, 7, 9 and 11, confirmed the structures of these compounds. Compounds 1-4 showed the most potent antitumor activity amon...
Background. Skin infections occur commonly and often present therapeutic challenges to practitioners due to the growing concerns regarding multidrug-resistant bacterial, viral, and fungal strains. The antimicrobial properties of zinc sulfate and copper sulfate are well known and have been investigated for many years. However, the synergistic activity between these two metal ions as antimicrobia...
Increasing bacterial resistance to commercial antibiotics has led to considering medicinal herb applications. This study aimed to identify chemical composition of essential oil of some native medical herbs and their antibacterial activity against Yersinia ruckeri compared with Enrofloxacin in in vitro experiments. The antibacterial activities of ethanolic extracts and essential oils of Eryngium...
