Chemistry:Ricobendazole

From HandWiki

Ricobendazole, also known as albendazole S-oxide, is a broad-spectrum benzimidazole anthelmintic. Its main use is for protecting livestock against nematode parasites.[1] Ricobendazole is the active sulfoxide metabolite of albendazole.[2]

Like mebendazole, ricobendazole inhibits tubulin polymerization.

Metabolic product of albendazole

Ricobendazole is produced in many species and in human liver when albendazole undergoes first-pass metabolism by the enzymes albendazole monooxygenase (sulfoxide-forming) (a cytochrome P450 oxidase) or albendazole monooxygenase (a flavin-containing monooxygenase.[3]
