Leishmania braziliensis. Furthermore, new simplified thiazolidenehydrazine derivatives were evaluated against Trypanosoma cruzi. The cytotoxicity of the active compounds on non-infected fibroblasts or macrophages was established in vitro to evaluate the selectivity of their anti-parasitic effects. Seven thiazolidenehydrazine derivatives and ten arylideneketones had good activity against the three parasites.

The present invention related to a process of preparation of pharmaceuti - cally acceptable formulations containing as active substance 3-(4-cinnamyl-l- piperazinyl)-amino derivatives of 3-formylrifamycine SV and 3-formylrifamycine S, which possess high activity against Gram- positive and Gram-negative microorganisms, as well as against tuberculous micobacteria (including atypical and rifamycin resistant), and to a method for the preparation of 3-(4-cinnamyl-l- piperazinyl)-amino derivatives of 3-formylrifamycine SV and 3-formylrifamycine S. The method for the preparation of pharmaceutical compositions is readily feasible, and does not require special equipment for its implementation. The process for preparing thecompounds is characterized by high yield and purity, using an environmental clean solvent - ethanol and water in the preparation and isolation of substances, and the absence of residual organic solvents in the final product.
