increased cytotoxicity.The rest of the series also exhibited potent antiparasitic activity with IC(50 ) values in the 1.72-4.43 microM/mL range. The cytotoxicity of the derivatives 5c and 5e was increased compared to the precursor compound, metronidazole, although they remain non-cytotoxic at concentrations much higher than the antiparasitic concentration of the two derivatives.

relative biological activity of 4- and 5-nitroimidazoles examined previously. In contrast, all three nitrosocompounds are considerably more bactericidal than their analogousnitrocompounds under both aerobic and anaerobic conditions, a finding that provides direct evidence that reduction of the nitro group is responsible for activation of the nitroimidazoles. Further evidence is also consistent with
