Discovery of 2-((4,6-dimethylpyrimidin-2-yl)thio)- N -phenylacetamide derivatives as new potent and selective human sirtuin 2 inhibitors
摘要:
Human sirtuin 2 (SIRT2) plays pivotal roles in multiple biological processes such as cell cycle regulation, autophagy, immune and inflammatory responses. Dysregulation of SIRT2 was considered as a main aspect contributing to several human diseases, including cancer. Development of new potent and selective SIRT2 inhibitors is currently desirable, which may provide a new strategy for treatment of related diseases. Herein, a structure-based optimization approach led to new 2-((4,6-dimethylpyrimidin-2-yl) thio)-N-phenylacetamide derivatives as SIRT2 inhibitors. SAR analyses with new synthesized derivatives revealed a number of new potent SIRT2 inhibitors, among which 28e is the most potent inhibitor with an IC50 value of 42 nM. The selectivity analyses found that 28e has a very good selectivity to SIRT2 over SIRT1 and SIRT3. In cellular assays, 28e showed a potent ability to inhibit human breast cancer cell line MCF-7 and increase the acetylation of alpha-tubulin in a dose-dependent manner. This study will aid further efforts to develop highly potent and selective SIRT2 inhibitors for the treatment of cancer and other related diseases. (C) 2017 Elsevier Masson SAS. All rights reserved.

A catalyst of a new type, cyclobutadiene complex [(C4Et4)Rh(p-xylene)]PF6, was found to promote selective reductive amination in the presence of carbon monoxide under mild conditions (1–3 bar, 90 °C). The reaction demonstrated perfect compatibility with a wide range of functional groups prone to reduction by conventional reducing agents. The developed system represents the first systematic investigation
