In 2021,International Journal of Pharmaceutical Sciences and Research included an article by Vikram, V.; Kishore, P. Ram; Kalaiyarasan, A.; Hariram, N.. Quality Control of ABTS Diammonium. The article was titled 《Protein profiling and isolation of bioactive hydrolysates with antioxidant activity from stem callus tissue of tinospora cordifolia (willd.) miers exposed to cyclodextrin》. The information in the text is summarized as follows:
This study is aimed to evaluate the effects of different concentrations of cyclodextrin, an auxin stabilizing agent, on callus growth from the stem explants of Tinospora cordifolia and to assess the antioxidant properties of the bioactive hydrolyzates of callus tissue using chymotrypsin, trypsin, pepsin, and papain. Cyclodextrin exerted a dose- and time-dependent effect on the callus growth. α-Chymotrypsin hydrolyzate showed the strongest 1,1-diphenyl-2-picrylhydrazyl (DPPH•) radical scavenging, while trypsin hydrolyzate exhibited the highest 2,2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS•+) activity. Protein profiling of callus tissue revealed a few tissue-specific bands at 41, 30, 20, and 9 kDa with varying intensities. A growth medium containing sucrose has a specific impact on the expression of these polypeptides. Purification of 30 kDa polypeptide by Sephadex-G50 revealed distinct quant. differences to different concentrations of cyclodextrin. This study suggested that T.cordifolia callus tissue protein hydrolyzates exhibited antioxidant efficacy, leading to the development of a nutraceutical agent in promoting health. The experimental process involved the reaction of ABTS Diammonium(cas: 30931-67-0Quality Control of ABTS Diammonium)
ABTS Diammonium(cas: 30931-67-0) belongs to anime. To avoid the problem of multiple alkylation, methods have been devised for “blocking” substitution so that only one alkyl group is introduced. The Gabriel synthesis is one such method; it utilizes phthalimide, C6H4(CO)2NH, whose one acidic hydrogen atom has been removed upon the addition of a base such as KOH to form a salt.Quality Control of ABTS Diammonium
