文摘
RDV-8 [C18H22N2O2S (ethyl 1-butyl-6-methyl-2-phenyl-4-thioxo-1,4-dihydropyrimidine-5-carboxylate)] is derived from the 4-thioxopyrimidine, and presents important clinical effects. The present study explored the RDV-8 effects in the proliferation of human peripheral blood mononuclear cells (PBMCs), as well as in a pleurisy-induced rat model. PBMCs were directly plated in four different RDV-8 concentrations (0.0125, 0.025, 0.05 and 0.1?mg/mL). RDV-8 decreased cell proliferation and monocyte chemotactic protein 1 synthesis. The interleukin 1 levels and the cytotoxic effect were not significantly affected by RDV-8 treatment. In the carrageenan-induced pleurisy model, the RDV-8 (3?mg/kg) treatment induced a significant reduction in the exudate volume, in the polymorphonuclear leukocyte migration and in the pleural exudate NO levels. The results indicate that RDV-8 may have an immunomodulatory effect, as well as anti-inflammatory actions suggesting that it could represent a new strategy in the inflammatory response modulation.
