چکیده
The synthesis and characterization of two Pt(II) Complexes with the isomeric ligands 4,5-dihydro-5-oxo- [1,2,4]triazolo-[ 1,5-a]pyrimidine (5HtpO) and 4,7-dihydro-7-oxo-[ 1,2,4]-triazolo-[ 1,5-a]pyrimidine (7HtpO) are described, as well as a Ru(III) complex with 7HtpO. The crystal structure of cis-[PtCl(2)(7HtpO)(2)].2H(2)O has been solved by X-ray diffraction analysis. In vitro activity of the new isolated complexes against the epimastigote form of T. cruzi, procyclic form of T. b. brucei and promastigote form of L. donnovani and P. characias has also been studied. The three complexes markedly affect the growth of the parasites and none of them shows cytotoxicity against macrophage of the J774.2 line at the heaviest dosages used.

Cytotoxicity of three new triazolo-pyrimidine derivatives against the plant trypanosomatid: Phytomonas sp. isolated from Euphorbia characias.
There is no effective chemotherapy against diseases caused by Phytomonas sp., a plant trypanosomatid responsible for economic losses in major crops. We tested three triazolo-pyrimidine complexes [two with Pt(II), and another with Ru(III)] against promastigotes of Phytomonas sp. isolated from Euphorbia characias. The incorporation of radiolabelled precursors, ultrastructural alterations and chan...
