Ames, James R. published the artcileMode of action of antiprotozoan agents. Electron transfer and oxy radicals, Product Details of C20H18BrN3, the publication is Life Sciences (1987), 41(16), 1895-902, database is CAplus and MEDLINE.
Cyclic voltammetry data were obtained for most of the main classes of antiprotozoan agents, specifically, nitroheterocycles, quinones, metal complexes and derivatives, iminium-type ions, and azo compounds The reductions were generally reversible in the range of -0.3 to -0.9 V. Catalytic production of oxidative pressure from redox cycling involving oxygen is believed to be an important mode of action by the medicinal agents. Literature data contribute support.
