title: [Latentiation of naphthylazoderivatives by polymerarization].
abstract: Five naphthylazoderivatives (of sulfadiazine, sulfamethazine, sulfathiazole, sulfamethoxazole, and sulfamonomethoxine) -- the first four displaying schistosomicidal activity -- were latentiated, in the form of polyamides of acrylic and methacrylic acids, by reacting those compounds with these polymers. In biological tests in mice experimentally infected by Schistosoma mansoni, the new nine compounds were found to be inactive. However, the original method of latentiation described in this paper has possibilities of wide application, owing to its favourable features: versatility of the reactive group of the polymer, lability of the bond (easily hydrolyzable) formed between drug and polymer, greater viability of reaction between the polyanhydride and the drug, and solubility in water of the polymers thus formed.
