Poly{[N-dodecyl-dithieno(3,2-b:2?,3?-d)pyrrole-2,6-diyl]-alt-[2,1,3-benzothiadiazole-4,7-diyl]} (PBTDTP) was successfully prepared via Stille coupling. The new polymer is soluble in common organic solvents such as chloroform (CHCl3), tetrahydrofuran (THF) and o-dichlorobenzene. Compared with N-alkyl dithieno[3,2-b:2?,3?-d]pyrrole (DTP) homopolymer, the maximum absorption of PBTDTP was red-shifted approximately 40 nm. The optical band gap of the polymer in film state is 1.55 eV calculated from the onset of absorption spectrum. The cyclic voltammetry measurements of the polymer depicted a HOMO energy level of -5.0 eV and a LUMO energy level of -3.3 eV of PBTDTP. This work demonstrates that this newly synthesized polymer is a promising p-type material for application in bulk hetero-junction organic solar cells.

The pro-inflammatory cytokine thymic stromal lymphopoietin (TSLP) plays a pivotal role in the pathophysiology of various allergy disorders that are mediated by type 2 helper T cell (Th2) responses, such as asthma and atopic dermatitis. TSLP forms a ternary complex with the TSLP receptor (TSLPR) and the interleukin-7-receptor subunit alpha (IL-7Ralpha), thereby activating a signaling cascade that culminates in the release of pro-inflammatory mediators. In this study, we conducted an in silico characterization of the TSLP:TSLPR complex to investigate the drugability of this complex. Two commercially available fragment libraries were screened computationally for possible inhibitors and a selection of fragments was subsequently tested in vitro. The screening setup consisted of two orthogonal assays measuring TSLP binding to TSLPR: a BLI-based assay and a biochemical assay based on a TSLP:alkaline phosphatase fusion protein. Four fragments pertaining to diverse chemical classes were identified to reduce TSLP:TSLPR complex formation to less than 75% in millimolar concentrations. We have used unbiased molecular dynamics simulations to develop a Markov state model that characterized the binding pathway of the most interesting compound. This work provides a proof-of-principle for use of fragments in the inhibition of TSLP:TSLPR complexation.

Palladium nanoparticles were deposited on multiwall WS2 nanotubes. The composite nanoparticles were characterized by a variety of techniques. The Pd nanoparticles were deposited uniformly on the surface of WS2 nanotubes. An epitaxial relationship between the (111) plane of Pd and the (013) plane of WS2 was mostly observed. The composite nanoparticles were found to perform efficiently as catalysts for cross-coupling (Heck and Suzuki) reactions. The role of the nanotubes? support in the catalytic process is briefly discussed.

Aim: An urgent need for the development of antibiotics with novel structures and unexploited targets. Materials & methods: Racemic chuangxinmycin was obtained via a novel synthesis route. Chiral preparative chromatography was used to separate chuangxinmycin from its epimers, and four stereoisomers were obtained. Fourteen derivatives were synthesized and their antibacterial activities were evaluated against Escherichia coli and Staphylococcus aureus. Results: Synthesized (3S, 4R)-chuangxinmycin showed antibacterial activity against S. aureus with minimum inhibitory concentration of 4-8 mug/ml (17.2-34.3 muM), which were consistent with the antibacterial activity of chuangxinmycin obtained by fermentation. The minimum inhibitory concentrations of other stereoscopic chuangxinmycin species and chuangxinmycin derivatives were >128 mug/ml. Conclusion: Results indicate that the antibacterial activity of chuangxinmycin is dependent on the stereoselectivity of structures, and that the electron cloud density and amphipathic properties of chuangxinmycin have little effect on its antibacterial activity.

Abstract A palladium complex derived from Pd2(dba)3 and tris(2,4,6-trimethoxyphenyl)phosphine catalyzes the addition reaction of thioesters to norbornenes, giving trans-2-acyl -3-organothionorbornanes. The trans-adducts are predominantly obtained with the acyl group at the endo-position and the organothio group at the exo-position. Aroyl and heteroaroyl thioesters as well as alkanoyl thioesters were reacted, including S-(4-tolyl) phenylthioglyoxylate and methyl 2-(4-tolylthio)-2-oxo-acetate.

HDAC inhibition is emerging as a new strategy for cancer therapy. We previously reported that Nhydroxy-3-{4-[2-(2-methyl-1H-indol-3-yl)-ethylsulfamoyl]-phenyl}-acrylamide (9) demonstrated potent histone deacetylases (HDAC) inhibition and anti-inflammatory effects. This continuous study provides detailed structureactivity relationship (SAR) of novel indol-3-ethylsulfamoylphenylacrylamides as anti-cancer agents. These compounds are endowed with potent HDAC inhibitory activity, almost 2.5 folds to 42 folds better than suberanilohydroxamic acid (SAHA). Compounds 8, 10, 11 and 17 exhibited significant inhibitory effects on various cancer cell lines with GI50 values in the range of 0.02 to 0.35 muM which are 10-50 folds better than SAHA. In-vivo nude mice model indicated the anti-angiogenic potential of these acrylamides. This study has indicated the potential of 3-{4-[2-(1-Ethyl-2-methyl-1H-indol-3-yl)-ethyl-N-tert-butoxycarbonylsulfamoyl]-phenyl}-N-hydroxy-acrylamide (11, mean GI50 = 0.04 muM) as a lead molecule for further development as anti-cancer agent.

Synthetic Route of 52409-22-0, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other?

In this work, by conjugating 2-cyanoacrylic acid (CA), 4-(benzo[c][1,2,5]thiadiazol-7-yl)benzoic acid (BTBA), 4-(7-ethynylbenzo[c][1,2,5]thiadiazol-4-yl)benzoic acid (EBTBA), and 4-((7-ethynylbenzo[c][1,2,5]thiadiazol-4-yl)ethynyl)benzoic acid (EBTEBA) to a binary electron-donor diphenylamine-phenanthrocarbazole (DPA-PC), we systematically investigate the impacts of electron-acceptors upon energy level, energy gap, light-harvesting ability, photovoltaic parameter, and cell stability of donor-acceptor dyes in photoelectrochemical cells. In conjunction with an ionic liquid composite electrolyte, the DPA-PC dye with EBTEBA as electron-acceptor yields a high power conversion efficiency of 8% and an outstanding stability after a 1000 h aging test under the soaking of full sunlight at 60C in a dye-sensitized solar cell. Femtosecond fluorescence up-conversion measurements have suggested that energy relaxation and electron injection both occur to dye molecules in the nonequilibrium excited states. Moreover, the time constants of injecting electrons from dye molecules in the excited states to titania are very dispersive for over 1 order of magnitude, mainly owing to the broad energy distribution of excited states.

The use of sulfones as electron-withdrawing groups in substrates for palladium-catalyzed decarboxylative allylation was explored. A previously published trifluoromethanesulfonyl-based substrate was highly reactive and selective under mild conditions, but the substrate scope was not readily expanded. Instead, 3,5-bis(trifluoromethyl)phenyl sulfones were employed, thereby simultaneously retaining most of the electron deficiency and providing facile synthetic access. Optimization of the catalytic conditions to maximize the product distribution to a synthetically useful level of the allylation product over the protonation side product proved extremely challenging, with inconsistent and irreproducible results afforded with Pd2(dba)3 as the palladium source. A variety of substrates were subjected to the optimized catalytic conditions of PdCp(1-cinnamyl) and Xantphos in tetrahydrofuran at 50 C for 30 min. These conditions were applicable to all substrates with the exception of the alpha,alpha-dimethyl allyl ester, which required more forcing conditions and afforded four products: the allylation and protonation products, as expected, along with a cyclopropylation product and an unprecedented pseudodimeric product. The mechanism for the formation of these unusual side products is considered.
