Quinaldic acid
Quinaldic acid, also known as quinaldate, 2-carboxyquinoline, or quinoline-2-carboxylic acid, belongs to the class of organic compounds known as quinoline carboxylic acids. These are quinolines in which the quinoline ring system is substituted by a carboxyl group at one or more positions. The quinoline ring system is a double-ring structure composed of a benzene and a pyridine ring fused at two adjacent carbon atoms. Quinaldic acid is a quinoline having a carboxy group at the 2-position. It is a solid that is moderately soluble in water with a melting point of 156°C. Quinaldic acid is a metabolite of tryptophan degradation that is formed via the kynurenine pathway; it is formed through the dehydroxylation of the intermediate kynurenic acid (PMID: 13385219). It is excreted in urine, and its urine concentration is decreased in individuals suffering from chronic alcoholism (PMID: 25754126). Quinaldic acid has been shown to inhibit proinsulin synthesis in pancreatic islet cells (PMID: 373355). Quinaldic acid has been shown to have anti-proliferative or anti-tumour effects and has been found to alter the expression of the p53 tumour suppressor gene as well as the phosphorylation of the p53 protein in in vitro studies (PMID: 30780127). A product of l-tryptophan catabolism, via kynurenic acid, found in human urine. [HMDB] Quinoline-2-carboxylic acid is an endogenous metabolite.

2-Oxoarginine
2-Oxoarginine is a guanidino compound metabolite of arginine catabolism. 2-Oxoarginine levels are increased in patients with argininemia (OMIM:207800). Argininemia, characterized by arginase deficiency (EC 3.5.3.1, catalyzes the last step of the urea cycle) is an autosomal recessive inborn error of metabolism caused by a defect in the final step in the urea cycle, the hydrolysis of arginine to urea and ornithine. Accumulation of arginine metabolites (such as guanidino compounds) especially 2-oxoarginine, may produce the central nervous system damage in argininemia. (PMID: 3433275 , 1588833 , 1690873 , 819629). 2-Oxoarginine has also been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). 2-Oxoarginine is a guanidino compound metabolite of arginine catabolism. 2-Oxoarginine levels are increased in patients with argininemia (OMIM:207800).
