Metabolite Identification
Common Name1H-Indole-3-carboxaldehyde
DescriptionIndole-3-carboxaldehyde (IAld or I3A), also known as 3-formylindole or 3-indolealdehyde, belongs to the class of organic compounds known as indoles. Indoles are compounds containing an indole moiety, which consists of pyrrole ring fused to benzene to form 2,3-benzopyrrole. I3A is an extremely weak basic (essentially neutral) compound (based on its pKa). In humans, I3A is a biologically active metabolite which acts as a receptor agonist at the aryl hydrocarbon receptor in intestinal immune cells. It stimulates the production of interleukin-22 which facilitates mucosal reactivity (PMID: 27102537 ). I3A is a microbially derived tryptophan metabolite produced by Clostridium and Lactobacillus (PMID: 30120222 , 27102537  ). I3A has also been found in the urine of patients with untreated phenylketonuria (PMID: 5073866 ). Outside of the human body, I3A has been detected, but not quantified in, several different foods, such as beans, Brussels sprouts, cucumbers, cereals and cereal products, and white cabbages. This could make I3A a potential biomarker for the consumption of these foods.
