[Latentiation of therapeutic drugs. VI. Preparation of l-amino-4-naphtylazoic ambonates of schistosomicides].

With the purpose of obtaining latent forms, with prolonged action and less toxic, of four schistosomicidal 1-amino-4-naphthylazoderivatives synthesized early, embonates of these compounds were prepared by reacting disodium and tetrasodium embonates with hydrochlorides of the four naphthylazoderivatives. The eight embonates thus obtained were sent for biological assays.
