Chemical and Pharmaceutical Bulletin, 1970 Adenosine 5'-phosphate was converted to the 2', 3'-cyclic phosphate by the treatment with dimethylformamide at reflux temperature. The reaction was shown to be proceeded by the initial release of the phosphoryl group as an"activated phosphoric acid"and rephosphorylated to furnish the 2', 3'-cyclic phosphate. In fact a ribonucleoside and phosphoric acid,

INTRACELLULAR Leishmania amazonensis KILLING INDUCED BY THE GUANINE NUCLEOSIDE 8-BROMOGUANOSINE
Revista do Instituto de Medicina Tropical de São Paulo, 1998 In this study we investigated the effect of 8-Bromoguanosine, an immunostimulatory compound, on the cytotoxicity of macrophages against Leishmania amazonensis in an in vitro system. The results showed that macrophages treated with 8-Bromoguanosine before
