General description

Chemical structure: benzimidazole

Application

Ricobendazole is a methylcarbamate benzimidazole with a broad-spectrum anthelmintic activity. Ricobendazole is a key metabolite of albendazole . It has been shown to induce apoptosis in human cancer cell line HT-29, possibly by arresting the cell cycle at the G2/M phase.

Biochem/physiol Actions

Methylcarbamate benzimidazoles [albendazole (ABZ), fenbendazole (FBZ), and their respective sulfoxide derivatives, albendazole sulfoxide (ABZSO) and oxfendazole (OXF)] are therapeutically important anthelmintic agents with low bioavailability. We studied their in vitro interaction with the apical ATP-binding cassette (ABC) drug efflux transporters

The peritoneal surface remains an important failure site for patients with colorectal cancer. We have recently shown that albendazole (ABZ), a safe and effective anthelmintic drug, has profound antitumor activity in hepatocellular cancer. Furthermore, albendazole also possesses unique physiochemical and

A high-performance liquid chromatographic method using polar organic mode was developed to analyze albendazole (ABZ), albendazole sulfone (ABZSO(2)) and the chiral and active metabolite albendazole sulfoxide (ABZSOX, ricobendazole) that was further applied in stereoselective fungal biotransformation studies. The chromatographic separation

Post-injection precipitation may cause poor and erratic drug absorption and tissue irritation at the injection site. Tissue tolerance and pharmacokinetics of a low pH ricobendazole (RBZ) injectable containing 20% hydroxypropyl-beta-cyclodextrin (HP-beta-CD) were simultaneously investigated after subcutaneous injection in sheep compared
