Description	Isovanillin is an aldehyde oxidase inhibitor[1]. Antispasmodic activities[2]. Antidiarrheal activities[3].
Related Catalog	Signaling Pathways >> Others >> Others Research Areas >> Metabolic Disease Research Areas >> Neurological Disease Natural Products >> Phenols
Target	Aldehyde oxidase[1]
In Vitro	Isovanillin is not a substrate for aldehyde oxidase and therefore it is metabolized to isovanillic acid predominantly by aldehyde dehydrogenase[1]. Isovanillin is relaxant of ileum contractions induced by 5-HT (IC50=356±50μM) [2].
In Vivo	Isovanillin (2 mg/kg & 5 mg/kg) and iso-acetovanillon (2 mg/kg & 5 mg/kg) both have antidiarrheal and anti-motility effect on gastrointestinal tract[3].
