The products are evaluated in vitro as trypanocidal agents. IntroductionWe have previously reported the synthesis of three series of new compounds and the biological evaluation against Trypanosoma cruzi of 1,2,6-Thiadiazin 1,1-dioxide derivatives, structurally related to Nifurtimox [1,2]. The in vitro assay showed that some of them exhibit significant activity against epimastigote forms of T. cruzi, but the cytotoxicity of this type of compounds against Vero cells was highest than the reference drug. ExperimentalIn this work we design new structures, changing the free radical generator. All the compounds were prepared according to the following synthetic pathway Results and DiscussionAll the compounds have been obtained with good yields, and have been characterized by IR, 1H-NMR, 13C-NMR and MS.All the products were tested in vitro against T. cruzi epimastigote forms and that more promising were tested their cytotoxicity.
