The article was titled 《Design and synthesis of adamantyl-substituted flavonoid derivatives as anti-inflammatory Nur77 modulators: Compound B7 targets Nur77 and improves LPS-induced inflammation in vitro and in vivo》, and you may find the article in Bioorganic Chemistry.Synthetic Route of C5H13NO2 The information in the text is summarized as follows:
In continuing our study on discovering new Nur77-targeting anti-inflammatory agents with natural skeletons, we combined adamantyl group and hydroxamic acid moiety with flavonoid nucleus, synthesized three series of flavonoid derivatives with a similar structure like CD437, and evaluated their activities against LPS-induced inflammation. Compound B7 was found to be an excellent Nur77 binder (Kd = 3.55 x 10-7 M) and a potent inhibitor of inflammation, which significantly decreased the production of cytokines in vitro, such as NO, IL-6, IL-1β, and TNF-α, at concentrations of 1.25, 2.5, and 5 μM. Mechanistically, B7 modulated the colocalization of Nur77 at mitochondria and inhibited the lipopolysaccharides (LPS)-induced inflammation via the blockade of NF-κB activation in a Nur77-dependent manner. Addnl., B7 showed in vivo anti-inflammatory activity in the LPS-induced mice model of acute lung injury (ALI). These data suggest that the Nur77-targeting flavonoid derivatives can be particularly useful for further pharmaceutical development for the treatment of inflammatory diseases such as ALI. In the experiment, the researchers used many compounds, for example, N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5Synthetic Route of C5H13NO2)
N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5) 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.Synthetic Route of C5H13NO2
