Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, Non-U.S. Gov’t, Bioorganic & Medicinal Chemistry called Unexpected small molecules as novel SIRT2 suicide inhibitors, Author is Chen, Xiaoxue; Zou, Yefang; Wang, Jie; Cao, Zhuoxian; Liu, Jingzi; Li, Yan; Zhao, Yonglong; He, Bin, which mentions a compound: 3222-47-7, SMILESS is O=C(O)C1=CN=C(C)C=C1, Molecular C7H7NO2, Safety of 6-Methylnicotinic acid.
A series of sirtuin inhibitor candidates were assembled based on an intermediate ester (1a) our accidently discovered. After screening and evaluation, several SIRT2 selective inhibitors were identified, which can inhibit all the deacetylation, defatty-acylation and debenzoylation of SIRT2. Among these inhibitors, compound 1e was the best SIRT2 selective inhibitors. The primary study on the inhibitory mechanism indicated that compound 1e may be a suicide inhibitor acting as an irreversible way. Given almost all reported sirtuin inhibitors are non-covalent, sirtuin covalent inhibitors are still need to be developed. These findings will facilitate for further development of SIRT2 selective and suicide inhibitors.
Compound(3222-47-7)Safety of 6-Methylnicotinic acid received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(6-Methylnicotinic acid), if you are interested, you can check out my other related articles.
