And the article was included in International Journal of Biological Macromolecules in 2020.Synthetic Route of C17H10O4 This article mentions the following:
The post-translational modification of proteins by nonenzymic glycation (NEG) and the accumulation of AGEs are the two underlying factors associated with the long-term pathogenesis in diabetes. Glyoxal (GO) is a reactive intermediate which has the ability to modify proteins and generate AGEs at a faster rate. Human serum albumin (HSA) being the most abundant serum protein has a higher chance to be modified by NEG. The key objective of the present study is to investigate the potency of chrysin and luteolin as antiglycating and antifibrillating agents in the GO-mediated glycation and fibril formation of HSA. AGEs formation were confirmed from the absorption and fluorescence spectral measurements. Both the flavonoids were able to quench the AGEs fluorescence intensity in vitro indicating the antiglycating nature of the mols. The formation of fibrils in the GO-modified HSA was confirmed by the Thioflavin T (ThT) fluorescence assay and the flavonoids were found to exihibit the antifibrillation properties in vitro. Docking results suggested that both the flavonoids interact with various amino acid residues of subdomain IIA including glycation prone lysines and arginines via non-covalent forces and further stabilized the structure of HSA, which further explains their mechanisms of action as antiglycating and antifibrillating agents. In the experiment, the researchers used many compounds, for example, 4-Phenyl-3H,3’H-spiro[furan-2,1′-isobenzofuran]-3,3′-dione (cas: 38183-12-9Synthetic Route of C17H10O4).
4-Phenyl-3H,3’H-spiro[furan-2,1′-isobenzofuran]-3,3′-dione (cas: 38183-12-9) belongs to benzofurans derivatives. Benzofuran is the “”parent”” of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants. They are also prone to polymerisation in the presence of concentrated mineral acids and Lewis acids.Synthetic Route of C17H10O4
