Albendazole S-oxide Usage And Synthesis
Chemical PropertiesWhite to Off-White Powder
UsesA metabolite of Albendazole, an anthelmintic
UsesTubulin polymerization or assembled inhibitors
DefinitionChEBI: Albendazole S-oxide is a sulfoxide. It is functionally related to an albendazole.
Biological ActivityRicobendazole is a key metabolite of albendazole and acts as an anthelmintic. It has been shown to induce apoptosis in human cancer cell line HT-29, possibly by arresting cell cycle at the G2/M phase.
Synthesis
1,3-Bis(methoxycarbonyl)-2-methyl-2-thiopseudoeura

34840-23-8

1,2-Benzenediamine, 4-(propylsulfinyl)-

66868-66-4

Albendazole S-oxide

54029-12-8

3.56 g (18 mmol) of 4-(1-propylsulfinyl)-1,2-diaminobenzene was dissolved in 45 mL of methanol and 1.03 mL of acetic acid and 3.84 g (19.8 mmol) of 1,3-bis(methoxycarbonyl)-S-methylisothiourea were added. The reaction mixture was heated to reflux for 2.5 hours, followed by cooling and removing the solvent under reduced pressure. The resulting white solid was digested with water, filtered, washed with ether and dried to give 4.1 g of white solid product, albendazole sulfoxide, with a melting point of 205°C to 216°C and a yield of 81%.

in vivo

Albendazole sulfoxide (0.5 mg/kg, i.m., BID, 15 days) reduces cyst size and weight in Balb/c mice infected with protoscoleces[3].
