Mechanism of Action

Oxamniquine may associate with an irreversible inhibition of the nucleic acid metabolism of the parasites. A hypothesis has been put forth that the drug is activated by a single step, in which a schistosome sulfotransferase enzyme converts oxamniquine into an ester (probably acetate, phosphate, or sulfate). Subsequently, the ester spontaneously dissociates, the resulting electrophilic reactant is capable of alkylation of schistosome DNA., Causes the worms to be dislodged from their usual site of residence in the mesenteric veins to the liver where they are retained and subsequently killed by host tissue reactions (eg, phagocytosis). The dislodgment of worms appears to result principally from contraction and paralysis of their musculature and subsequent immobilization of their suckers, which causes the worms to detach from the blood vessel wall, thereby allowing passive dislodgement by normal blood flow., Hycanthone-sensitive and hycanthone-resistant schistosomes (which are also sensitive and resistant to oxamniquine) were exposed in vitro to tritium-labelled oxamniquine. The initial uptake of the drug into the schistosomes was essentially the same for the 2 strains. The homogenate of worms incubated with tritiated oxamniquine was fractionated and a purified DNA fraction was obtained by ethanol precipitation, RNAase and protease digestion, repeated phenolchloroform extractions, cesium chloride gradient centrifugation and extensive dialysis. The DNA fraction from sensitive worms contained radioactive oxamniquine at a level corresponding to about 1 drug molecule per 50,000 base pairs, while the DNA from resistant worms contained essentially no drug. The results support the hypothesis that oxamniquine, like hycanthone, exerts its activity by alkylating macromolecules of sensitive schistosomes.
