Gainesville, FL, USADFT calculations were used to access information about structure, energy and electronic properties of series of phenyl- and phenoxymethyl-(thio)semicarbazone derivatives with demonstrated activity against the larvae of Aedes aegypti in stage L4. The way as the thiosemicarbazone derivatives can interact with solvents like DMSO and water were analyzed from the comparison between calculated and experimental 1H NMR chemical shifts. The evidences of thiosemicarbazone derivatives making H-bond interaction to solvent have provide us insights on how they can interact with a potential A. aegypti’s biological target, the Sterol Carrier Protein-2

Recife, PE, BrasilCancer remains a high incidence and mortality disease, causing around 8.2 million of deaths in the last year. Current chemotherapy needs to be expanded, making research for new drugs a necessary task. Immune system modulation is an emerging concept in cancer cell proliferation control. In fact, there are a number of mechanisms underlying the role immune system plays in tumor cells. In this work, we describe the structural design, synthesis, antitumor and immunomodulatory potential of 31 new 1,3-thiazole and thiosemicarbazone compounds. Cisplatin was used as anticancer drug control. Cytotoxicity against J774A.1 macrophages and antitumor activity against HT-29 and Jurkat cells was determined. These 1,3-thiazole and thiosemicarbazone compounds not only exhibited cytotoxicity in cancer cells, but were able to cause irreversible cancer cell damage by inducing necrosis and apoptosis. In addition, these compounds, especially pyridyl-thiazoles compounds, regulated immune factors such as interleukin 10 and tumor necrosis factor, possible by directing immune system in favor of modulating cancer cell proliferation. By examining their pharmacological activity, we were able to identify new potent and selective anticancer compounds

Twenty-seven new molecules were assessed for their immunosuppressive effect toward TNFα, IFNγ, IL-2 and IL-6 production and antiproliferative activity. The best activity profile was observed for the (6a-f) series, which presents phthalyl and thiazolidinone groups

Centro de Ciências da Saúde. Departamento de Ciências Farmacêuticas. Recife, PE, BrasilThe discovery of new antiparasitic compounds against Trypanosoma cruzi, the etiological agent of Chagas disease, is necessary. Novel aryloxy/aryl thiosemicarbazone-based conformationally constrained analogs of thiosemicarbazones (1) and (2) were developed as potential inhibitors of the T. cruzi protease cruzain, using a rigidification strategy of the iminic bond of (1) and (2). A structureeactivity relationship analysis was performed in substituents attached in both aryl and aryloxy rings. This study indicated that apolar substituents or halogen atom substitution at the aryl position improved cruzain inhibition and antiparasitic activity in comparison to unsubstituted thiosemicarbazone. Two of these compounds displayed potent inhibitory antiparasitic activity by inhibiting cruzain and consequently were able to reduce the parasite burden in infected cells and cause parasite cell death through necrosis. In conclusion, we demonstrated that conformational restriction is a valuable strategy in the development of antiparasitic thiosemicarbazones
