Metabolite Identification
Common Name5-Acetylamino-6-formylamino-3-methyluracil
Description5-Acetylamino-6-formylamino-3-methyluracil, also known as AFMU, belongs to the class of organic compounds known as hydroxypyrimidines. These are organic compounds containing a hydroxyl group attached to a pyrimidine ring. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 5-Acetylamino-6-formylamino-3-methyluracil is an extremely weak basic (essentially neutral) compound (based on its pKa). 5-acetylamino-6-formylamino-3-methyluracil can be biosynthesized from paraxanthine and acetyl-CoA; which is catalyzed by the enzyme arylamine N-acetyltransferase 2. In humans, 5-acetylamino-6-formylamino-3-methyluracil is involved in caffeine metabolism.
