Molle, Edgar; Mutlu, Hatice; Theato, Patrick published the artcile< Synthesis and Post-Polymerization Modification of Poly(N-(4-Vinylphenyl)Sulfonamide)s>, Name: Perfluorophenyl acrylate, the main research area is polyvinylphenylsulfonamide post modification acrylate aza Michael reaction; free radical polymerization; post-polymerization modification; sulfonamide-based polymers; β-amino acids.

Herein, a straightforward synthesis of a novel class of polymers, i.e., poly(N-(4-vinylphenyl)sulfonamide)s, and their monomers is reported. A set of monomers with varying electron densities, fine-tuned by different substituents on the aromatic sulfonamide moiety, is polymerized by free radical polymerization featuring low molar masses (2300 ≤ Mn ≤ 3200 g mol-1) and low dispersities (1.15 ≤ Dj ≤ 1.47). Further, the post-polymerization modification of the obtained polymers via aza-Michael addition with electron-deficient alkenes is demonstrated using organic superbases as catalysts, paving the way toward the facile synthesis of novel polymeric protected β-amino acid derivatives

As part of our research effort to discover B-Raf kinase inhibitors, we prepared a series of C-3 substituted N-(3-(pyrazolo[1,5-a]pyrimidin-7-yl)phenyl)-3-(trifluoromethyl)benzamides. X-ray crystallog. studies revealed that one of the more potent inhibitors bound to B-Raf kinase without forming a hinge-binding hydrogen bond. With basic amine residues appended to C-3 aryl residues, cellular activity and solubility were enhanced over previously described compounds of this class.

Zaleskaya-Hernik, Marta; Dobrzycki, Lukasz; Karbarz, Marcin; Romanski, Jan published the artcile< Fluorescence Recognition of Anions Using a Heteroditopic Receptor: Homogenous and Two-Phase Sensing>, Product Details of C19H34O2, the main research area is crown ether squaramide ion pair receptor fluorescent sensor; anthracene; crown ethers; fluorescent sensors; ion pair receptors; squaramides; sulfate extraction.

In contrast to monotopic receptor 3, the anthracene functionalized squaramide dual-host receptor 1 is capable of selectively extracting sulfate salts, as was evidenced unambiguously by DOSY, mass spectrometry, fluorescent and ion chromatog. measurements. The receptors were investigated in terms of anion and ion pair binding using the UV-vis and 1H NMR titrations method in acetonitrile. The reference anion receptor 3, lacking a crown ether unit, was found to lose the enhancement in anion binding induced by the presence of cations. Besides the ability to bind anions in an enhanced manner exhibited by ion pair receptors 2 and 4, changing the 1-aminoanthracene substituent resulted in their exhibiting a lower anion affinity than receptor 1. By using receptor 1 and adjusting the water content in organic phase it was possible to selectively detect sulfates both by “”turn-off”” and “”turn-on”” fluorescence, and to do so homogenously and under interfacial conditions. Such properties of receptor 1 have allowed the development of a new type of sensor capable of recognizing and extracting potassium sulfate from the aqueous medium across a phase boundary, resulting in an appropriate fluorescent response in the organic solution

Fan, Pei-Ru; Zhao, Xue; Wei, Ze-Hui; Huang, Yan-Ping; Liu, Zhao-Sheng published the artcile< Robust immobilized enzyme reactor based on trimethylolpropane trimethacrylate organic monolithic matrix through ""thiol-ene"" click reaction>, Application In Synthesis of 3290-92-4, the main research area is immobilized enzyme reactor trimethylolpropane trimethacrylate organic monolithic matrix.

A novel immobilized enzyme reactor (IMER) based on trimethylolpropane trimethacrylate (TRIM) organic monolith was prepared by “”thiol-ene”” click reaction. The IMERs were made by fabricating TRIM monolith core in advance. There were residual double bonds on the surface of TRIM monolith, in which click reaction can be performed with the free thiol groups of trypsin at room temperature to bond the trypsin on the monolithic column without addnl. introducing an active functional group. The enzyme activity was characterized by kinetic parameters Km and Vmax and determined by off-line chromatog. The performance of the IMERs was evaluated by digesting standard protein BSA and compared with in-solution digestion method. By using IMER 5 min, the sequence coverage rate of BSA was 79.41%, which was similar to that in-solution digestion for 12 h (82.7%). The applicability of the IMERs in complex samples was assessed by digesting crude protein extracts from egg white and mouse liver, identifying 28 (104 peptides) and 843 (3916 peptides) proteins, resp. All results indicated that the IMERs have great potential in high-throughput proteomics anal.

Human malignant glioblastoma (GBM) is a highly invasive and lethal brain tumor. Targeting of integrin downstream signaling mediators in GBM such as focal adhesion kinase (FAK) seems reasonable and recently demonstrated promising results in early clin. studies. Herein, we report the structure-guided development of a series of covalent inhibitors of FAK. These new compounds displayed highly potent inhibitory potency against FAK enzymic activity with IC50 values in the nanomolar range. Several inhibitors retarded tumor cell growth as assessed by a cell viability assay in multiple human glioblastoma cell lines. They also significantly reduced the rate of U-87 cell migration and delayed the cell cycle progression by stopping cells in the G2/M phase. Furthermore, these inhibitors showed a potent decrease of autophosphorylation of FAK in glioblastoma cells and its downstream effectors Akt and Erk as well as nuclear factor-κB. These data demonstrated that these inhibitors may have the potential to offer a promising new targeted therapy for human glioblastomas.
