N-Acetyl-3-methylhistidine, an N-acetyl-L-amino acid, belongs to the class of organic compounds known as histidine and derivatives. Histidine and derivatives are compounds containing histidine or a derivative thereof resulting from a reaction of histidine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. N-Acetyl-3-methylhistidine is an acetylated derivative of 3-methylhistidine and a very strong basic compound (based on its pKa). N-Acetyl-3-methylhistidine has been found to be associated with prostate cancer. Higher circulating levels of five of these N-acetylated amino acids, namely, N-δ-acetylornithine, N-acetyl-1-methylhistidine, N-acetyl-3-methylhistidine, N-acetylhistidine, and N2,N5-diacetylornithine, were associated with kidney failure. The NAT8 gene has been associated with 14 N-acetylated amino acids, including N-Acetyl-3-methylhistidine.
