General description

Potassium antimonyl tartrate trihydrate is a trivalent antimonial compound. It has been reported to be more toxic than pentavalent antimony (Pentostam) against Leishmania species. Its crystal structure has been investigated by the three-dimensional X-ray and white radiation neutron diffraction techniques. It crystallizes in space group C2221. Unit cell dimensions reported were: a = 11.192(2), b = 11.696(3), and c = 25.932(5)Å.

Application

Potassium antimonyl tartrate trihydrate was employed as an Sb(III)-containing drug to investigate its ability to induce cell death associated with DNA fragmentation in axenic amastigotes of Leishmania infantum†
It may also be used as a standard solution to determine the metalloid concentration such as Sb(III) and Sb(V) in surface soil, using high performance liquid chromatography coupled to inductively coupled plasma-mass spectrometry (HPLC-ICP-MS).

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
