Azaserine and Acivicin are classical and irreversible inhibitors of γ-Glutamyltranspeptidase
Definition
ChEBI: An L-alpha-amino acid that is L-alanine in which the methyl group is replaced by a (5S)-3-chloro-4,5-dihydro-1,2-oxazol-5-yl group. A glutamine analogue antimetabolite, it interferes with
lutamate metabolism and several glutamate-dependent synthetic enzymes. It is obtained as a fermentation product of Streptomyces sviceus bacteria.
Enzyminhibitor
This cytotoxic isoxazole and copper chelator (FW = 178.57 g/mol; CAS 42228-92-2; Source: Streptomyces sviceus), also known as L-(aS,5S)-aamino-3-chloro-4,5-dihydro-5-isoxazoleacetic acid, AT-125, and NSC165301, strongly inhibitsγ-glutamyl transpeptidase. Its clinical application in cancer treatment failed as a consequence of unacceptable toxicity, and the cause(s) of the desired and undesired biological effects have never been elucidated and only limited information about acivicin-specific targets is available. Target deconvolution by quantitative mass spectrometry (MS) has now revealed acivicin’s preference for the specific aldehyde dehydrogenase known as ALDH4A1 by binding to the catalytic site. Moreover, siRNA-mediated downregulation of ALDH4A1 results in a severe inhibition of cell growth, a finding that may explain acivicin’s cytotoxicity. Targets: Acivicin is thought to be a glutamine analogue, an assumption that is amply supported by its ability to inhibit the following enzymes that possess essential amidohydrolase activities that generate nascent ammonia: asparagine synthetase; carbamoyl-phosphate synthetase; anthranilate synthase; glutamate synthase; CTP symthetase; amidophospho-ribosyltransferase; glutamin(asparagin)ase, or glutaminase-asparaginase; GMP synthase, glutamine-dependent; phosphoribosyl-formylglycinamidine synthetase (formylglycinamidine ribonucleotide synthetase; thiol oxidase; γ-glutamyl hydrolase; imidazole-glycerol phosphate synthetase.
