binding region and therefore blocked the access of the peptide substrate to the FAD, finally leading to the demethylase activity inhibition of LSD1. The findings indicate that aryl hydrazines are newscaffolds for the design of LSD1 inhibitors, the identification of D8 provides further evidence for our previously proposed general principle that fused heterocycles with an amine group are potentially active

Abstract Targeting bromodomain-containing protein 4 (BRD4) has been proved to be an effective strategy for cancer therapy. To date, numerous BRD4 inhibitors and degraders have been identified, some of which have advanced into clinical trials. In this work, a focused library of new [1,2,4]triazolo[1,5-a]pyrimidine derivatives were discovered to be able to inhibit BRD4. WS-722 inactivated BRD4 (BD1/BD2)

LSD1 has been recognized as a promising strategy for cancer therapy. To date, some small-molecule inhibitors are currently being investigated in clinical trials. Herein we report the design, synthesis and biochemical characterization of [1,2,4]triazolo[1,5-a]pyrimidinederivatives as new LSD1 inhibitors. Of these compounds, compound C26 inhibited LSD1 in a reversible manner (IC50 = 1.72 μM) and showed
组蛋白赖氨酸特异性脱甲基酶1(LSD1 / KDM1A)与癌症的发展有关,靶向LSD1已被认为是一种有前途的癌症治疗策略。迄今为止,一些小分子抑制剂目前正在临床试验中进行研究。在这里我们报告[1,2,4]三唑并[1,5- a ]嘧啶衍生物作为新型LSD1抑制剂的设计,合成和生化特性。在这些化合物中,化合物C26以可逆方式抑制LSD1(IC 50 = 1.72μM),并且相对于MAO-A / B具有对LSD1的选择性。另外,化合物C26显示出与LSD1的FAD竞争性结合。有趣的是,C26不会抑制辣根过氧化物酶(HRP)并淬灭H 2O 2,因此排除了C26抑制LSD1的原因是HRP抑制和H 2 O 2的消耗。在LSD1过表达的A549细胞中,化合物C26浓度依赖性地诱导H3K4me1 / me2和H3K9me2的积累,并显示细胞靶标与LSD1的结合。此外,化合物C26以浓度依赖性方式显着抑制
Discovery of the Triazolo[1,5-<i>a</i>]Pyrimidine-Based Derivative WS-898 as a Highly Efficacious and Orally Bioavailable ABCB1 Inhibitor Capable of Overcoming Multidrug Resistance
Targeting P-glycoprotein (ABCB1 or P-gp) has been recognized as a promising strategy to overcome multidrug resistance. Here, we reported our medicinal chemistry efforts that led to the discovery of the triazolo[1,5-a]pyrimidine derivative WS-898 as a highly effective ABCB1 inhibitor capable of reversing paclitaxel (PTX) resistance in drug-resistant SW620/Ad300, KB-C2, and HEK293/ABCB1 cells (IC50 =
