Animal experiment: | Mice[1]Mice are infected i.p. with 104 bloodstream trypomastigotes taken from an infected mouse and suspended in 0.1 mL of phosphate-buffered saline, pH 7.2. The infection is allowed to develop for 24 h before treatment is begun. Ten infected mice are used as controls and received only excipient, 1% carboxymethylcellulose by the i.p. route in a 0.1 ml volume. The other mice receive a single dose of the diluted or suspended Potassium Melarsonyl (20, 40, 60 μmol/kg) in the same manner. Six mice are used per dose. The trypanocidal activity is evaluated by the mean survival time of treated mice for each dose[1]. |

Melarsonyl (Melarsonic acid) is an anthelmintic agent which can inhibit parasite potently.
For acute infections produced by T. brucei brucei GVR, Potassium Melarsonyl exhibits trypanocidal activities. Potassium Melarsonyl (Trimelarsan) cures less than 50% mice at a dose of 25 μmol/kg for 4 consecutive days. At 60 μmol/kg, it cures all the mice in a chronic-infection model[1].

Evaluation of DL-alpha-difluoromethylornithine against susceptible and drug-resistant Trypanosoma brucei brucei
Acta Trop 1991 Jan;48(3):223-32.PMID:1671624DOI:10.1016/0001-706x(91)90050-t.
The antitrypanosomal activity of the ornithine decarboxylase inhibitor DL-alpha-difluoromethylornithine (DFMO, eflornithine) was tested in ten stocks and one clone of the hemoflagellate Trypanosoma brucei brucei in an in vitro system. They showed varying levels of susceptibility to DFMO, their IC50 (the concentration which inhibited growth by 50%) values ranging from 81-691 microM. Differences in DFMO susceptibility were also demonstrated in mice. Combinations of Melarsonyl potassium (mel W; trimelarsan) and DFMO showed an additive effect in vitro in a mel W-susceptible and a mel W-resistant stock, but an antagonistic effect in a mel W- and DFMO-susceptible clone. Combinations of suramin and DFMO showed an antagonistic effect in vitro in a suramin-susceptible clone, but a potentiation in a suramin-resistant stock.
