Design, synthesis and structure–activity relationship studies of novel sirtuin 2 (SIRT2) inhibitors with a benzamide skeleton
摘要:
Human sirtuin 2 (SIRT2) is an attractive target molecule for development of drugs to treat neurodegenerative diseases and cancer, because SIRT2 inhibitors have a protective effect against neurodegeneration and an anti-proliferative effect on cancer stem cells. We designed and synthesized a series of benzamide derivatives as SIRT2 inhibitor candidates. Among them, compound 17k showed the most potent SIRT2-inhibitory activity (IC50 = 0.60 mu M), with more than 150-fold selectivity over SIRT1 and SIRT3 isoforms (IC50 > 100 mu M).

The present invention provides novel diarylurea derivatives (compounds of formula (I)) and their uses. The compounds of the present invention are demonstrated to be allosteric modulators of the CB1 receptor, and therefore useful for the treatment of diseases and conditions mediated by CB1.
The Suzuki−Miyaura cross-coupling of aryl phosphates using Ni(PCy3)2Cl2 as an inexpensive, bench-stable catalyst is described. Broad substrate scope and high efficiency are demonstrated by the syntheses of more than 40 biaryls and by constructing complex organic molecules. The poor reactivity of aryl phosphates relative to aryl halides is successfully employed to construct polyarenes by selective cross-coupling
Arylmetals are highly valuable carbon nucleophiles that are readily and inexpensively prepared fromarylhalides or arenes and widely used on both laboratory and industrial scales to react directly with a wide range of electrophiles. Although C−Cbond formation has been a staple of organic synthesis, the direct transfer of primary amino (−NH2) and hydroxyl (−OH) groups to arylmetals in a scalable and environmentally
