Melarsonyl (Melarsonic acid)

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].
