Song, Hyeseung published the artcileDiscovery of potent and selective rhodanine type IKKβ inhibitors by hit-to-lead strategy, Recommanded Product: 4-(4-Chlorophenoxy)benzaldehyde, the main research area is preparation rhodanine IKK NFkappaB inhibitor antiinflammatory cancer; rheumatoid arthritis rhodanine derivative.

Regulation of NF-κB activation through the inhibition of IKKβ has been identified as a promising target for the treatment of inflammatory and autoimmune disease such as rheumatoid arthritis. In order to develop novel IKKβ inhibitors, we performed high throughput screening toward around 8000 library compounds, and identified a hit compound containing rhodanine moiety. We modified the structure of hit compound to obtain potent and selective IKKβ inhibitors. Throughout hit-to-lead studies, we have discovered optimized compounds which possess blocking effect toward NF-κB activation and TNFα production in cell as well as inhibition activity against IKKβ. Among them, compound 3q showed the potent inhibitory activity against IKKβ, and excellent selectivity over other kinases such as p38α, p38β, JNK1, JNK2, and JNK3 as well as IKKα.

Rajapaksa, Naomi S. published the artcileDiscovery of Potent Benzolactam IRAK4 Inhibitors with Robust in Vivo Activity, Application In Synthesis of 35112-05-1, the main research area is preparation benzolactam IRAK4 inhibitor structure.

IRAK4 kinase activity transduces signaling from multiple IL-1Rs and TLRs to regulate cytokines and chemokines implicated in inflammatory diseases. As such, there is high interest in identifying selective IRAK4 inhibitors for the treatment of these disorders. We previously reported the discovery of potent and selective dihydrobenzofuran inhibitors of IRAK4. Subsequent studies, however, showed inconsistent inhibition in disease-relevant pharmacodynamic models. Herein, we describe application of a human whole blood assay to the discovery of a series of benzolactam IRAK4 inhibitors. We identified potent mol. 19 which achieves robust in vivo inhibition of cytokines relevant to human disease.

Kato, Yusuke published the artcileStructural 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.

The application of nitroxide radical mediator and porphyrin dye to dye-sensitized solar cell (DSSC) was reported. A typical porphyrin 5,10,15,20-tetra(4-carboxyphenyl)porphyrin-Zn(II) (ZnTCCP) was utilized as a dye sensitizer and 1-pyrene carbonate as light-harvesting antenna dye. DSSC using the nitroxide radical 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) and ZnTCCP with deoxychoal acid gave maximum properties. The DSSC which was common absorption of ZnTCCP and pyrene was decrease of photovoltaic performance. Such decrease gave less absorption of ZnTCCP due to excess pyrene dye.

Lloyd-Jones, Guy C. published the artcileEnantioselective homoallyl-cyclopropanation of dibenzylideneacetone by modified allylindium halide reagents-rapid access to enantioenriched 1-styryl-norcarene, Recommanded Product: (S)-Methyl 2-(2-chlorophenyl)-2-hydroxyacetate, the main research area is asym synthesis styryl norcarene homoallyl cyclopropanation ring closing metathesis; enantioselective cyclopropanation allylindium halide dibenzylideneacetone modifier.

Dibenzylideneacetone reacts with in situ-generated allylindium halide reagents to yield 2-(3”-butenyl)-1,1-bis[(E)-2′-phenylethenyl]cyclopropane I via a homoallyl-cyclopropanation reaction. A range of enantiomerically enriched ligands have been tested as stoichiometric asym. modifiers for this process. Enantiopure compounds such as cinchona alkaloids, ephedra, aminoalcs. and tartaric acid derivatives, which have proven of utility as asym. modifiers for the indium-mediated allylation of aldehydes and ketones, were very inefficient in the homoallyl-cyclopropanation. However, mandelic acid derivatives, in particular mandelates, were found to be of significant potential. The absolute stereochem. of the cyclopropane I has been determined by degradation to 1,1-dicarboxymethyl-2-butylcyclopropane, converging with an independent enantioselective synthesis starting from hexene. Under optimized conditions by using allylindium iodide reagents and working-up with aqueous Na2SO3 to avoid iodine-mediated polymerization, I can be generated in 86% yield and 94/6 er enantiopurity with (S)-Me mandelate as modifier. The cyclopropane product I undergoes RCM to afford 1-styrylnorcarene II without loss of enantiopurity.
