Satranidazole-d3 is the deuterium labeled Satranidazole. Satranidazole is an orally active insecticide and antimicrobial agent with high electron affinity. Satranidazole forms reduced nitro intermediates, which interact with DNA, causing helix instability, strand breakage and release of thymidine derivatives. Satranidazole exhibits antitrichomonal activity against Trichomonas vaginalis and Trichomonas foetus, and antiamoebic activity in rodent models of hepatic amoebiasis and caecal amoebiasis. Satranidazole inhibits the replication of bacteriophage phiX174 DNA. Satranidazole can be used in research related to caecal amoebiasis, trichomoniasis and anaerobic bacterial infections.
