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.
Thieno[3,2-<i>b</i>]pyrrole-5-carboxamides as New Reversible Inhibitors of Histone Lysine Demethylase KDM1A/LSD1. Part 1: High-Throughput Screening and Preliminary Exploration
increasingly recognized as a potential therapeutic target in oncology. We report on a high-throughput screening campaign performed on KDM1A/CoREST, using a time-resolved fluorescence resonance energy transfer (TR-FRET) technology, to identify reversible inhibitors. The screening led to 115 hits for which we determined biochemical IC50, thus identifying four chemicalseries. After data analysis, we have

analogue development by bioisosterism/retro-bioisosterism, which resulted in 20 new substituted 3-benzoic acid derivatives. Compounds were active against MtDHFR, with IC50 values ranging from 7 to 40 μM, where compound 4e not only had the best inhibitory activity (IC50 = 7 μM), but also was 71-fold more active than the original fragment MB872. The 4e inhibition kinetics indicated an uncompetitive mechanism

prepare TN-16, and then we applied the same reaction for the synthesis of aza-analogs. In brief, we prepared a library of 62 novel compounds, and three of these retained nanomolar potencies. TN-16 and the activeanalogs are cytotoxic on cancer cell lines and, as expected from antitubulin agents, induce G2/M cell cycle arrest. These agents lead to a disruption of the microtubules and an increase in α-tubulin
