Morinidazole is an orally active and 5-nitroimidazole antimicrobial agent that undergoes extensive metabolism in humans via N + -glucuronidation and sulfation. Morinidazole can be used for bacterial infections research including appendicitis and pelvic inflammatory disease (PID) caused by anaerobic bacteria In Vitro Morinidazole can be metabolized to N + -glucuronide of S-morinidazole [M8-1] and N + -glucuronide of R-morinidazole [M8-2] via N + -glucuronidation, and sulfate conjugate of morinidazole [M7] via sulfation. M7 is a substrate for organic anion transporter 1 (OAT1) and OAT3 (K m =28.6 and 54.0 μM, respectively), M8-1 and M8-2 are the substrates for OAT3. Morinidazole shows activity against Trichomonas vaginalis and Entamoeba histolytica in vitro, with MIC values of 2 μg/mL and 3 μg/mL, respectively. MCE has not independently confirmed the accuracy of these methods. They are for reference only. In Vivo Morinidazole (20 mg/kg or 25 mg/kg; p.o.; single dose) inhibits Trichomonas vaginalis and Entamoeba histolytica in vivo in rats with EC 50 s of 20 mg/kg and 25 mg/kg, respectively. Morinidazole (50 mg/kg; i.v.; 0.25, 0.75, 1.5 h) shows a different concentration in tissues after intravenous injection, with a higher concentration in liver, kidney, plasma than lung, heart, and spleen in mice.

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
