Moustakim, Moses published the artcileDiscovery of an MLLT1/3 YEATS Domain Chemical Probe, SDS of cas: 94084-75-0, the main research area is MLLT1 YEATS domain chem probe; MLLT1; MLLT3; YEATS; chemical probes; epigenetics.

YEATS domain (YD) containing proteins are an emerging class of epigenetic targets in drug discovery. Dysregulation of these modified lysine-binding proteins has been linked to the onset and progression of cancers. We herein report the discovery and characterization of the first small-mol. chem. probe, SGC-iMLLT, for the YD of MLLT1 (ENL/YEATS1) and MLLT3 (AF9/YEATS3). SGC-iMLLT is a potent and selective inhibitor of MLLT1/3-histone interactions. Excellent selectivity over other human YD proteins (YEATS2/4) and bromodomains was observed Furthermore, our probe displays cellular target engagement of MLLT1 and MLLT3. The first small-mol. X-ray co-crystal structures with the MLLT1 YD are also reported. This first-in-class probe mol. can be used to understand MLLT1/3-associated biol. and the therapeutic potential of small-mol. YD inhibitors.

Volynets, Galyna published the artcileIdentification of protein kinase fibroblast growth factor receptor 1 (FGFR1) inhibitors among the derivatives of 5-(5,6-dimethoxybenzimidazol-1-yl)-3-hydroxythiophene-2-carboxylic acid, Application of 5,6-Dimethoxy-1H-benzo[d]imidazole, the main research area is dimethoxy benzimidazolyl hydroxythiophene carboxylate preparation FGFR1 inhibitor cancer.

Abstract: Fibroblast growth factor receptor 1 (FGFR1) plays an important role in tumorigenesis, suggesting that inhibitors of this protein kinase may become important compounds for the development of anticancer agents. Using mol. docking approach, we have identified a novel class of FGFR1 inhibitors belonging to the derivatives of 5-(5,6-dimethoxybenzimidazol-1-yl)-3-hydroxythiophene-2-carboxylic acid. It was revealed that the most promising compound 5-(5,6-dimethoxybenzimidazol-1-yl)-3-[2-(methanesulfonyl)benzyloxy]thiophene-2-carboxylic acid Me ester inhibits FGFR1 with an IC50 value of 150 nM in in vitro kinase assay. The structure-activity relationships have been studied, and the binding mode of this chem. class has been proposed. Graphic abstract: [Figure not available: see fulltext.].

Alverez, Celeste N. published the artcileIdentification of a New Heterocyclic Scaffold for Inhibitors of the Polo-Box Domain of Polo-like Kinase 1, Product Details of C11H10N2O2, the main research area is triazolo quinazolinone preparation anticancer drug discovery pharmacokinetic SAR.

As a mitotic-specific target widely deregulated in various human cancers, polo-like kinase 1 (Plk1) has been extensively explored for anticancer activity and drug discovery. Although multiple catalytic domain inhibitors were tested in preclin. and clin. studies, their efficacies are limited by dose-limiting cytotoxicity, mainly from off-target cross reactivity. The C-terminal noncatalytic polo-box domain (PBD) of Plk1 has emerged as an attractive target for generating new protein-protein interaction inhibitors. Here, we identified a 1-thioxo-2,4-dihydro-[1,2,4]triazolo[4,3-a]quinazolin-5(1H)-one scaffold that efficiently inhibits Plk1 PBD but not its related Plk2 and Plk3 PBDs. Structure-activity relationship studies led to multiple inhibitors having ≥10-fold higher inhibitory activity than the previously characterized Plk1 PBD-specific phosphopeptide, PLHSpT (Kd ~450 nM). In addition, S-Me prodrugs effectively inhibited mitotic progression and cell proliferation and their metabolic stability was determined These data describe a novel class of small-mol. inhibitors that offer a promising avenue for future drug discovery against Plk1-addicted cancers.

Guo, Jing published the artcileDesign, synthesis, structure-activity relationships study and X-ray crystallography of 3-substituted-indolin-2-one-5-carboxamide derivatives as PAK4 inhibitors, Product Details of C10H7ClN2O, the main research area is indolinone preparation SAR docking PAK4 inhibitor crystal mol structure; Indolin-2-one; X-ray crystallography; p21-activated kinase 4.

We have previously described the identification of indolin-2-one-5-carboxamides as potent PAK4 inhibitors. This study expands the structure-activity relationships on our original series by presenting several modifications in the lead compounds, I and II. A series of novel derivatives was designed, synthesized, and evaluated in biochem. and cellular assay. Most of this series displayed nanomolar biochem. activity and potent antiproliferative activity against A549 and HCT116 cells. The representative compound III exhibited excellent enzyme inhibition (PAK4 IC50 = 25 nM) and cellular potency (A549 IC50 = 0.58 μM, HCT116 IC50 = 0.095 μM). An X-ray structure of compound III bound to PAK4 was obtained. Crystallog. anal. confirmed predictions from mol. modeling and helped refine SAR results. In addition, Compound III displayed focused multi-targeted kinase inhibition, good calculated drug-likeness properties. Further profiling of compound III revealed it showed weak inhibitory activity against various isoforms of human cytochrome P 450.

Xing, Jing published the artcileRational design of 5-((1H-imidazol-1-yl)methyl)quinolin-8-ol derivatives as novel bromodomain-containing protein 4 inhibitors, Computed Properties of 30086-17-0, the main research area is imidazolylmethylquinolinol bromodomain containing protein 4 inhibitor; 8-OH-Quinoline; Anti-cancer activity; Bromodomain-containing protein 4; Computer-aided drug design; Early ADME/T evaluation; Rational hit-to-lead optimization.

Bromodomain-containing protein 4 (BRD4), an epigenetic reader of acetyl lysine, has emerged as a promising therapeutic target for many diseases including cancer, inflammation and heart failure. The previous study reported that nitroxoline, an FDA approved antibiotic, showed potential BRD4 inhibitory activity and antiproliferation activity against leukemia cell lines. In this study, the authors further explored the structure-activity relationship (SAR) around nitroxoline and employed the previously developed machine learning based activity scoring function BRD4LGR for further anal. To improve the cellular level activity, physico-chem. properties were optimized using computational approaches. Then the candidates were tested for their ADME/T profiles. Finally, based on this rational hit-to-lead optimization strategy, 3 drug-like BRD4 inhibitors were obtained, with different profiles on cell line selectivity for multiple myeloma, leukemia and triple neg. breast cancer. Further mechanism study showed these compounds could down-regulate c-Myc to inhibit cancer cell growth. This work illustrates the application of multiple computer-aided drug design techniques in a hit-to-lead optimization scenario, and provides novel potent BRD4 inhibitors with different phenotype propensities for future cancer treatment.

Takeuchi, Yoshio published the artcileAdjacent lone pair (ALP) effects in heteroaromatic systems. 2. Isotope exchange of ring hydrogens in nitro- and fluoroimidazoles, Formula: C3H3FN2, the main research area is adjacent lone pair effect; hydrogen exchange nitroimidazole fluoroimidazole; imidazole nitro fluoro exchange.

The ring protons of nitro- and fluoroimidazoles (and their N-Me derivatives) undergo base-catalyzed exchange in D2O by a combination of carbanion (C) and ylide (Y) pathways, which involve proton abstraction from the neutral imidazole species and from the imidazolium ion, resp. In 4-substituted imidazoles, C exchange occurs more readily at C-5 than at C-2, log kC correlating with σo° for the NH- and with σp° for the N-Me series. For 1-methyl-4-nitroimidazole, t1/2 = 2 min at C-5 (50°, 0.2 N NaOD). In 1-methyl-5-X-imidazoles, exchange at C-4 occurs only via the Y pathway, carbanion formation in the neutral species being retarded by the adjacent lone pair (ALP) effect at N-3. The same effect is seen in the lack of C exchange at C-4 in 1-methylimidazoles. The ALP effect is considerably weaker or nonexistent at C-2. Most exchanges across the ring show correlations of log k with ςm°. 4-Alkylimidazoles (but not 1,4-dialkylimidazoles) show enhanced C exchange at C-5, which may result from the existence of a trace concentration of the ketimine tautomer. Enhanced exchange at C-5 in 2-fluorohistidine is ascribed to a combination of the ketimine effect, C exchange involving catalysis by OH and intramol. general-base catalysis by the side-chain primary-amine function. The use of buffer catalysis for the T labeling of poorly reactive imidazoles is described.
