Aminomalonic acid and its congeners as potential in vivo inhibitors of L-asparagine synthetase
Enzyme 1979;24(1):36-47.PMID:35346DOI:10.1159/000458626.
Aminomalonic acid is a strong in vitro inhibitor of L-asparagine synthetase from Leukemia 5178Y/AR and from mouse pancreas; the agent is formally competitive with L-aspartic acid (Ki = 0.0023 M and 0.0015 M for the tumoral and pancreatic enzymes, respectively). Since Aminomalonic acid is unstable and inert in vivo as an inhibitor of L-asparagine synthetase, attempts were made to deliver it to the site of its intended action via precursors: the diamide (2-aminomalonamide), the diester (diethylaminomalonate), and the keto acid (ketomalonic acid). Each of these putative 'pro drugs' was shown to be susceptible to metabolism to aminomalonate by mammalian and bacterial enzymes, in vitro. In vivo, aminomalonamide failed to inhibit tumoral L-asparagine synthetase at any time period up to 24 h after its oral or intraperitoneal administration. The diester and keto acid were similarly inactive. However, with specialized techniques it was possible to demonstrate that the diamide significantly inhibited the amidation and/or incorporation of L-aspartic acid into the L-asparaginyl residues of protein. Chemical manipulations of Aminomalonic acid aimed at introducing irreversibly reacting functions are warranted.
Aminomalonic acid: identification in Escherichia coli and atherosclerotic plaque
Proc Natl Acad Sci U S A 1984 Feb;81(3):722-5.PMID:6366787DOI:10.1073/pnas.81.3.722.
Aminomalonic acid (Ama) has been isolated from proteins of Escherichia coli and human atherosclerotic plaque. The presence of Ama has important biological implications because the malonic acid moiety potentially imparts calcium binding properties to protein. Ama was obtained by anaerobic alkaline hydrolysis and identified by chromatographic behavior, quantitative acid-mediated decarboxylation to glycine, and unambiguous gas chromatographic/mass spectral detection. The chromatographic, chemical, and mass spectral properties of naturally occurring Ama were identical to those of the synthetic compound. Amino acid analysis and GC/mass spectrometry also revealed the presence of beta-carboxyaspartic acid and gamma-carboxyglutamic acid in the base hydrolysate of human atherosclerotic plaque. The ratio of Ama to beta-carboxyaspartic acid to gamma-carboxyglutamic acid was 20:1:10, and the quantity of Ama per 1,000 glycine residues was 0.2. Ama is a relatively unstable, minor amino acid in complex structures such as bacteria or tissues. This may explain why it has escaped detection previously, despite intensive investigation.
Detection and possible origins of Aminomalonic acid in protein hydrolysates
Anal Biochem 1992 Feb 14;201(1):152-7.PMID:1621954DOI:10.1016/0003-2697(92)90188-d.
Aminomalonic acid (Ama) was first detected in alkaline hydrolysates of proteins in 1984. In this work we describe our search for the origin of Aminomalonic acid in alkaline hydrolysates of proteins. We have developed a technique for quantitation of Aminomalonic acid based upon gas chromatography/mass spectrometry. Using this technique, we find approximately 0.3 Ama/1000 amino acids in hydrolysates of Escherichia coli protein. We have demonstrated that Ama is not formed from any of the 20 major amino acids during the hydrolysis procedure. Furthermore, the amount of Ama found does not depend on the presence of small amounts of O2 during the hydrolysis. Thus far, we have not been able to demonstrate an artifactual origin for Ama. The results described above suggest that Ama may indeed be a constituent of proteins before the hydrolysis procedure. Possible origins of Ama include errors in protein synthesis and oxidative damage to amino acid residues in proteins.
Malonofungin: an antifungal Aminomalonic acid from Phaeoramularia fusimaculans
Acta Chem Scand (Cph) 1994 Mar;48(3):240-51.PMID:8155432DOI:10.3891/acta.chem.scand.48-0240.
In screening for antifungal metabolites, a novel compound, malonofungin, exhibiting growth inhibitory activity against Botrytis cinerea (grey mould), has been isolated from fermentations of Phaeoramularia fusimaculans CBS 616.87. Its structure is established as (E)-(3R,4S,5S)-5-acetoxy-2-amino-2-carboxy-3,4-dihydroxy-14-oxoicos++ +-6-enoic acid, representing an addition to the rare class of naturally occurring aminomalonic acids. 1H NMR data and extensive use of CD spectroscopy have been utilized to establish the absolute stereochemistry of malonofungin. The structural and biological relationship of malonofungin to previously reported fungal metabolites is discussed.
GC/MS-based metabolomics strategy to analyze the effect of exercise intervention in diabetic rats
Endocr Connect 2019 Jun;8(6):654-660.PMID:31042671DOI:10.1530/EC-19-0012.
Metabolomics was used to explore the effect of exercise intervention on type 2 diabetes. The rat model of type 2 diabetes was induced by an injection of streptozocin (30 mg/kg), after fed with 8-week high-fat diet. The rats were divided into three groups: the control group, the diabetic model group (DM) and the diabetes + exercise group (DME). After exercise for 10 weeks, blood samples were collected to test biomedical indexes, and 24-h urine samples were collected for the metabolomics experiment. In the DME group, fasting blood glucose (FBG), both total cholesterol (TC) and total plasma triglycerides (TG), were decreased significantly, compared with those in the DM group. Based on gas chromatography-mass spectrometry (GC/MS), a urinary metabolomics method was used to study the mechanism of exercise intervention on diabetes mellitus. Based on the principal component analysis (PCA), it was found that the DM group and control group were separated into two different clusters. The DME group was located between the DM group and the control group, closer to the control group. Twelve significantly changed metabolites of diabetes mellitus were detected and identified, including glycolate, 4-methyl phenol, benzoic acid, 1H-indole, arabinitol, threitol, ribonic acid, malic acid, 2,3-dihydroxy-butanoic, Aminomalonic acid, l-ascorbic acid and 3-hydroxy hexanedioic acid. After exercise, seven metabolites were significantly changed, compared with the control group, the relative contents of benzoic acid, Aminomalonic acid, tetrabutyl alcohol and ribonucleic acid in the diabetic exercise group decreased significantly. The relative contents of 2,3-dihydroxybutyric acid, l-ascorbic acid and 3-hydroxy adipic acid increased significantly. l-ascorbic acid and Aminomalonic acid which related with the oxidative stress were significantly regulated to normal. The results showed that exercise could display anti-hyperglycemic and anti-hyperlipidemic effects. The exercise had antioxidation function in preventing the occurrence of complications with diabetes mellitus to some extent. The work illustrates that the metabolomics method is a useful tool to study the mechanism of exercise treatment.
