The inhibition of growth of Escherichia coli B by series of 6-azaanalogs of pyrimidine nucleosides, their precursors, and analogs of cancerostatic agents 5-fluorouracil and arabinosylcytosine is reported. A very high antibacterial activity is observed with most of the 5-fluorouracil nucleosides where a cleavage (30%) to 5-fluorouracil is observed at the most active compounds (5-fluorouridine, 5-fluoro-2'-deoxyuridine). Arabinosylcytosine and its derivatives express very low activity.
The in vitro effects of the aminoglycoside antibiotics tobramycin and gentamicin were compared, chiefly against Pseudomonas aeruginosa but also against Staphylococcus aureus and Proteus species. These antibiotics did not differ greatly in effectiveness. Studies with the electron microscope showed that short exposure to tobramycin altered the morphologic appearance of the bacterial cell.
SummaryThe antifungal activity of jaritin and haloprogin against Candida albicans is similar. In vitro they had less activity than clotrimazole and miconazole, but the activity was independent of inoculum size.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
