In Vitro and In Vivo Activity of a Synthetic Halogenated Quinoline Against Cryptococcus neoformans.
The minimum inhibitory concentrations of a halogenated quinoline, 3-amino-7-chloro-3,4-dihydro-1-hydroxycarbostyril (CBS), against nine clinical strains of Cryptococcus neoformans were determined by in vitro testing. The CBS was fungistatic at a minimum concentration of 0.2 mug/ml at 48 h for several strains. In vivo toxicity studies were carried out in mice. Mice were also infected with C. neoformans strain Price and injected with various concentrations of CBS. Mean life expectancy of treated groups of animals was increased over infected untreated controls.
