3-Methyldioxyindole

1,3-Dihydro-3-hydroxy-3-methyl-2H-indol-2-one

C9H9NO2 (163.06332540000002)


3-Methyldioxyindole is a metabolite of aldehyde dehydrogenase (NAD+) (K00128)(EC 1.2.1.3) formed during 3-methylindole metabolism (PMID: 88251990). It is the major urinary metabolite of 3-methylindole. (PMID: 2519781). It is thought that 3-Methyldioxyindole is an in vivo oxidation product of 3-methylindole which is a metabolic product of tryptophan, produced by bacteria in the colon (PMID: 2796599). 3-Methyldioxyindole is a metabolite of aldehyde dehydrogenase (NAD+) (K00128)(EC 1.2.1.3) formed during 3-methylindole metabolism (PMID: 88251990). It is the major urinary metabolite of 3-methylindole. (PMID: 2519781).

4-oxo-4-Pyridin-3-yl-butyraldehyde

C9H9NO2 (163.06332540000002)


4-Oxo-1-(3-pyridyl)-1-butanone, also known as gamma-oxo-3-Pyridinebutanal or 3-Succinoylsemialdehyde-pyridine, is classified as a member of the Aryl alkyl ketones. Aryl alkyl ketones are ketones have the generic structure RC(=O)R, where R = aryl group and R=alkyl group. 4-Oxo-1-(3-pyridyl)-1-butanone is considered to be soluble (in water) and relatively neutral

   

4-(3-Pyridyl)-3-butenoic acid

(3E)-4-(pyridin-3-yl)but-3-enoic acid

C9H9NO2 (163.06332540000002)


This compound is a reactant in the pathways: nicotine degradation II and nicotine degradation III, where it is converted into 4-(3-pyridyl)-butanoate. This is one of the hypothesized intermediate reactions of nicotine being converted to 3-pyridylacetate. (BioCyc) This compound is likely associated with nicotine accumulation disorders.
