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.
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.
