He, Zhangxu;Jiao, Haomiao;An, Qi;Zhang, Xin;Dan, Zengyangzong;Xu, Jiale;Liu, Hongmin;Ma, Liying;Zhao, Wen research published 《 Discovery of novel 4-phenylquinazoline-based BRD4 inhibitors for cardiac fibrosis》, the research content is summarized as follows. Bromodomain containing protein 4 (BRD4), as an epigenetic reader, can specifically bind to the acetyl lysine residues of histones and has emerged as an attractive therapeutic target for various diseases, including cancer, cardiac remodeling and heart failure. Herein, we described the discovery of hit 5 bearing 4-phenylquinazoline skeleton through a high-throughput virtual screen using 2,003,400 compound library (enamine). Then, structure-activity relationship (SAR) study was performed and 47 new 4-phenylquinazoline derivatives toward BRD4 were further designed, synthesized and evaluated, using HTRF assay set up in our laboratory Eventually, we identified compound C-34, which possessed better pharmacokinetic and physicochem. properties as well as lower cytotoxicity against NRCF and NRCM cells, compared to the pos. control JQ1. Using computer-based mol. docking and cellular thermal shift assay, we further verified that C-34 could target BRD4 at mol. and cellular levels. Furthermore, treatment with C-34 effectively alleviated fibroblast activation in vitro and cardiac fibrosis in vivo, which was correlated with the decreased expression of BRD4 downstream target c-MYC as well as the depressed TGF-β1/Smad2/3 signaling pathway. Taken together, our findings indicate that novel BRD4 inhibitor C-34 tethering a 4-phenylquinazoline scaffold can serve as a lead compound for further development to treat fibrotic cardiovascular disease.

Fragment-based drug discovery (FBDD) is a popular method in academia and the pharmaceutical industry for the discovery of early lead candidates. Despite its wide-spread use, the approach still suffers from laborious screening workflows and a limited diversity in the fragments applied. Presented here is the design, synthesis, and biol. evaluation of the first fragment library specifically tailored to tackle both these challenges. The 3F library of 115 fluorinated, Fsp3-rich fragments is shape diverse and natural-product-like with desirable physicochem. properties. The library is perfectly suited for rapid and efficient screening by NMR spectroscopy in a two-stage workflow of 19F NMR and subsequent 1H NMR methods. Hits against four diverse protein targets are widely distributed among the fragment scaffolds in the 3F library and a 67% validation rate was achieved using secondary assays. This collection is the first synthetic fragment library tailor-made for 19F NMR screening and the results demonstrate that the approach should find broad application in the FBDD community.

An efficient methodol. for the synthesis of a diverse class of N-heterocyclic moieties, such as quinoxalines, benzimidazoles and quinazolines, was developed in water using bio-renewable alcs. The quinoxalines were successfully synthesized from a wide range of diamines and nitroamines with diols in air. Interestingly, benzimidazoles and quinazolines were synthesized with excellent isolated yields without using any external base. Finally, the preparative scale synthesis of various N-heterocycles and pharmaceutically active quinoxalines established the practicability of this protocol. For this iridium system, a metal-ligand cooperative mechanism was proposed based on kinetic and DFT studies.

Mori, Nobuo; Asano, Yuzuru; Irie, Toshiko; Tsuzuki, Yojiro published the artcile< Intramolecular hydrogen bonds. XIII. Preferable conformation of α-hydroxy carboxylic and o-hydroxybenzoic acids>, Product Details of C8H7ClO3, the main research area is salicylates conformation IR; conformation IR salicylates; IR conformation salicylates; mandelates conformation IR; hydroxybutyrates conformation IR.

The ir hydroxyl and carbonyl stretching absorption spectra of salicylic, mandelic, and a-hydroxyisobutyric acid (I) were measured in dilute CCl4. The spectral data indicate that the first two acids exist exclusively in an internally bonded conformation, one where the phenolic and the alc. hydroxyl groups form a H bond with the carbonyl O atom of the cis-carboxyl structure, while I takes, apart from such a conformation, another internally bonded conformation, one where the hydroxyl group of the trans-carboxyl structure interacts with the alc. O atom.

Kato, Yusuke; Hin, Niyada; Maita, Nobuo; Thomas, Ajit G.; Kurosawa, Sumire; Rojas, Camilo; Yorita, Kazuko; Slusher, Barbara S.; Fukui, Kiyoshi; Tsukamoto, Takashi published the artcile< Structural basis for potent inhibition of D-amino acid oxidase by thiophene carboxylic acids>, Category: chlorides-buliding-blocks, the main research area is thiophene carboxylate inhibitor amino acid oxidase DAO crystal structure; Drug discovery; Flavoenzyme; Molecular dynamics; Schizophrenia; X-ray crystallography.

A series of thiophene-2-carboxylic acids and thiophene-3-carboxylic acids were identified as a new class of DAO inhibitors. Structure-activity relationship (SAR) studies revealed that small substituents are well-tolerated on the thiophene ring of both the 2-carboxylic acid and 3-carboxylic acid scaffolds. Crystal structures of human DAO in complex with potent thiophene carboxylic acids revealed that Tyr224 was tightly stacked with the thiophene ring of the inhibitors, resulting in the disappearance of the secondary pocket observed with other DAO inhibitors. Mol. dynamics simulations of the complex revealed that Tyr224 preferred the stacked conformation irresp. of whether Tyr224 was stacked or not in the initial state of the simulations. MM/GBSA indicated a substantial hydrophobic interaction between Tyr244 and the thiophene-based inhibitor. In addition, the active site was tightly closed with an extensive network of hydrogen bonds including those from Tyr224 in the stacked conformation. The introduction of a large branched side chain to the thiophene ring markedly decreased potency. These results are in marked contrast to other DAO inhibitors that can gain potency with a branched side chain extending to the secondary pocket due to Tyr224 repositioning. These insights should be of particular importance in future efforts to optimize DAO inhibitors with novel scaffolds.

Zhang, Wei; Mei, Yu; Huang, Xiao; Wu, Peng; Wu, Haihong; He, Mingyuan published the artcile< Size-Controlled Growth of Silver Nanoparticles onto Functionalized Ordered Mesoporous Polymers for Efficient CO2 Upgrading>, SDS of cas: 3240-10-6, the main research area is silver nanoparticle catalyst functionalized mesoporous polymer carbon dioxide; CO2 carboxylation; heterogeneous catalysis; mesoporous materials; monodispersed silver; size-controlled synthesis.

Highly dispersed metallic Ag nanoparticles (AgNPs) are promising heterogeneous catalysts for carboxylative coupling of terminal alkynes with CO2 under mild conditions. Yet their size-controlled synthesis is very challenging due to the high surface energy. Here the authors prepared amino-functionalized ordered mesoporous polymers as hosts for anchoring AgNPs. Control experiments and computations showed that electron-rich amines confined in mesochannels with varying electron d. and steric hindrance, creating localized active zones (LAZ) to control the growth of AgNPs. The particle size of AgNPs grows along with the increased volume of LAZ around nitrogen species. The authors also revealed that the catalytic activity of Ag-based catalysts is size-dependent and increases with decreasing particle size. Building on these findings, the authors report a facile 1-pot synthesis strategy for preparing amine-incorporated ordered mesoporous polymer (NOMP) with a high sp. surface area, small LAZ volume, and uniform amine sites with controllable loading. These features gave ultrasmall and monodispersed Ag nanoparticles. Remarkably, Ag@NOMP gave a quant. target yield under the conditions of 1 atm CO2 pressure and 50°, showing superior catalytic activity in the CO2 carboxylation compared to other mesoporous analogs.
