N-Acetyl-L-phenylalanine
N-Acetyl-L-phenylalanine or N-Acetylphenylalanine, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. N-Acetyl-L-phenylalanine can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-Acetyl-L-phenylalanine is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-phenylalanine. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\\\% of all human proteins and 68\\\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT’s (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-acetylphenylalanine can be released by an N-acylpeptide hydrolase from peptides generated by proteolytic degradation (PMID: 16465618). In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free phenylalanine can also occur. In particular, N-Acetyl-L-phenylalanine can be biosynthesized from L-phenylalanine and acetyl-CoA by the enzyme phenylalanine N-acetyltransferase (EC 2.3.1.53). N-Acetyl-L-phenylalanine is a potential uremic toxin and is considered as a hazardous amphipathic metabolite of phenylalanine (PMID: 4038506). Many N-acetylamino acids, including N-acetylphenylalanine, are classified as uremic toxins (PMID: 26317986; PMID: 20613759). Uremic toxins are a diverse group of endogenously produced molecules that, if not properly cleared or eliminated by the kidneys, can cause kidney damage, cardiovascular disease and neurological deficits (PMID: 18287557). N-Acetyl-L-phenylalanine appears in large amount in urine of patients with phenylketonuria (PKU), which is a human genetic disorder due to the lack of phenylalanine hydroxylase, the enzyme necessary to metabolize phenylalanine to tyrosine (PMID: 3473611). N-Acetyl-L-phenylalanine is a product of enzyme phenylalanine N-acetyltransferase [EC 2.3.1.53] which is found in the phenylalanine metabolism pathway. N-Acetyl-L-phenylalanine is produced for medical, feed, and nutritional applications such as in the preparation of aspartame. Afalanine (N-Acetyl-DL-phenylalanine) is also approved for use as an antidepressant. Acetylphenylalanine is a hazardous amphipathic metabolite of phenylalanine. It appears in large amount in urine of patients with phenylketonuria which is a human genetic disorder due to the lack of phenylalanine hydroxylase, the enzyme necessary to metabolize phenylalanine to tyrosine. Acetylphenylalanine is a product of enzyme phenylalanine N-acetyltransferase [EC 2.3.1.53] in the pathway phenylalanine metabolism. (KEGG; Wikipedia) [HMDB] N-Acetyl-L-phenylalanine (N-Acetylphenylalanine), the principal acylamino acid in Escherichia coli, is synthesized from L-phenylalanine and acetyl-CoA[1].

4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone
4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone (also known as NNK) is a potent tobacco-specific nitrosamine derived from nicotine. It plays a key role in human tobacco-related cancers (PMID:24830349). NNK is found in cured tobacco and is also produced during its burning or combustion in cigarettes. NNK is abundantly present in cigarette smoke (20-280 ng/cigarette). Electronic cigarettes (e-cigarettes) do not convert nicotine to NNK due to their lower operating temperatures. NNK is a procarcinogen. This means it must be activated by cytochrome P450 enzymes (CYP2A6 and CYP2B6) to become a carcinogen (PMID:24830349). NNK can also be activated by myeloperoxidase (MPO) and epoxide hydrolase (EPHX1). All activation processes lead to the formation of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol from NNK, which is called NNAL (PMID:24830349). NNAL can be detoxified via glucuronidation via glucuronidases. Once NNK is activated to NNAL, this compound initiates a cascade of signalling pathways (for example ERK1/2, NFκB, PI3K/Akt, MAPK, FasL, K-ras), resulting in uncontrolled cellular proliferation and tumorigenesis. NNK is known as a mutagen and can cause point mutations that affect cell growth proliferation and differentiation. NNK also targets the SULT1A1, TGF-beta, and angiotensin II genes. NNK plays a key role in gene silencing, gene modification, and carcinogenesis. NNK has been implicated in tumour promotion by activating nicotinic acetylcholine receptors (nAChRs) and β-adrenergic receptors (β-AdrRs), leading to downstream activation of parallel signal transduction pathways that facilitate tumour progression (PMID:24830349). Antioxidants such as EGCG (from green tea) inhibit lung tumorigenesis by NNK. 4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is a potent tobacco-specific nitrosamine in animals. It has been suggested to play a role in human tobacco-related cancers. P450 1A2 catalyzed the formation of keto alcohol and 4-oxo-1-(3-pyridyl)-1-butanone (keto aldehyde) from NNK, with the keto alcohol being the major metabolite. Phenethyl isothiocyanate (PEITC0 is an effective inhibitor of the carcinogenicity or toxicity of chemicals that are activated by P450 1A2.( PMID: 8625495) [HMDB] D009676 - Noxae > D002273 - Carcinogens
Phenylpropionylglycine
Phenylpropionylglycine is an acyl glycine. Acyl glycines are normally minor metabolites of fatty acids. However, the excretion of certain acyl glycines is increased in several inborn errors of metabolism. In certain cases the measurement of these metabolites in body fluids can be used to diagnose disorders associated with mitochondrial fatty acid beta-oxidation. Acyl glycines are produced through the action of glycine N-acyltransferase (EC 2.3.1.13) which is an enzyme that catalyzes the chemical reaction: acyl-CoA + glycine < -- > CoA + N-acylglycine. The detection of phenylpropionylglycine in urine after an oral load of phenylpropionic acid can be used to diagnose deficiency of medium-chain acyl-CoA dehydrogenase, a frequent and treatable metabolic defect.
