General description

Potassium antimonyl tartrate trihydrate is a trivalent antimony compound. It has been reported to be a leishmanicidal compound and exhibits more toxic action than pentavalent antimony (Pentostam) against Leishmania species. Three-dimensional X-ray and white radiation neutron diffraction methods have been reported to investigate the crystal structure of its optically active form (dipotassium di-μ-d-tartrato (4)-bis(antimonate(III)) trihydrate). Unit cell dimensions reported were: a = 11.192(2), b = 11.696(3), and c = 25.932(5)Å.

application

Potassium antimonyl tartrate trihydrate may be used as an Sb(III)-containing drug to investigate its ability to induce cell death associated with DNA fragmentation in axenic amastigotes of Leishmania infantum.

The basic treatment of leishmaniasis consists in the administration of pentavalent antimonials. The mechanisms that contribute to pentavalent antimonial toxicity against the intracellular stage of the parasite (i.e., amastigote) are still unknown. In this study, the combined use of several

The mechanism(s) of activity of pentavalent antimony [Sb(V)] is poorly understood. In a recent study, we have shown that potassium antimonyl tartrate, a trivalent antimonial [Sb(III)], was substantially more potent than Sb(V) against both promastigotes and axenically grown amastigotes of
