Dittrich, Jonas;Kather, Michael;Holzberger, Anna;Pich, Andrij;Gohlke, Holger research published ã€?Cumulative submillisecond all-atom simulations of the temperature-induced coil-to-globule transition of poly(N-vinylcaprolactam) in aqueous solutionã€? the research content is summarized as follows. Poly(N-vinylcaprolactam) (PNVCL) polymers are stimuli-responsive and change their conformation in aqueous solutions upon changes in salt concentration, concentration of organic solvents, or temperature, making these mols. highly interesting for tailored release of drugs or fabrication of sensors or actuators. At lower critical solution temperature (LCST), PNVCL chains undergo a transition from a coil to a globule and become insoluble In contrast to other polymers, however, PNVCL has received much less attention as to elucidating driving forces of its coil-to-globule transition at an atomistic level. Here, we show by a combined computational and exptl. study that upon temperature increase, PNVCL chains dissolved in water experience an increase of intramol. interactions between C3 and C4 of the caprolactam ring. Therefore, more favorable cavity formation energies and the increase of intramol. interactions outweigh the loss in polar and hydrophobic solvation, and the loss of configurational entropy in the coil-to-globule transition and, thus, may be considered driving forces of the polymer’s collapse at LCST. These results are based on mol. dynamics simulations of in total 600μs length and transition (free) energy computations that have been validated internally and against exptl. data. We systematically tested the influence of the polymer’s length, concentration, tacticity, of the thermodn. ensemble, and of the water model. Tacticity was found to be most influential, with atactic polymers showing the strongest tendency to collapse. The presented approach should be applicable to scrutinize at the atomistic level the impact of, for example, ion and polymer dispersity on the coil-to-globule transition of PNVCL, and the LCST behavior of other polymers.

We report the design of hetero-bifunctional small mols. that selectively target p38α and p38β for degradation These proteolysis targeted chimeras (PROTACs) are based on an ATP competitive inhibitor of p38α and p38β, which is linked to thalidomide analogs to recruit the Cereblon E3 ubiquitin ligase complex. Compound synthesis was facilitated by the use of a copper catalyzed “click” reaction. We show that optimization of the linker length and composition is crucial for the degradation-inducing activity of these PROTACs. We provide evidence that these chem. compounds can induce degradation of p38α and p38β but no other related kinases at nanomolar concentrations in several mammalian cell lines. Accordingly, the PROTACs inhibit stress and cytokine-induced p38α signaling. Our compounds contribute to understanding the development of PROTACs, and provide a useful tool to investigate functions of the p38 MAPK pathway and its involvement in diseases.

When primary aromatic amines were used as the substrates, the reactions produce urea derivatives RNHC(O)NHR. The electronic and steric effects from the substrates on the formylation and urealation reactions were observed and discussed. The recovery and reusability of zinc powder were investigated, showing that zinc powder can be reused in the formylation reaction without loss of catalytic activity. The anal. on the reactants/products mixture after filtering out the zinc powder showed that zinc concentration in the mixture is low to 1 ppm.

Hu, Chaolei;Xu, Wenjing;Conrads, Christian Martin;Wu, Jingnan;Pich, Andrij research published 《 Visible light and temperature dual-responsive microgels by crosslinking of spiropyran modified prepolymers》, the research content is summarized as follows. Light-responsive microgels are interesting colloidal systems with potential applications in the biotechnol. and medicine. However, synthesis of light-responsive microgels with high loading of photoswitchable mols. is still very challenging. Herein we developed a new method to synthesize light and temperature dual-responsive spiropyran-modified poly(N-vinylcaprolactam) microgels. The novel and straightforward microgels synthesis route involved: a) synthesis of poly(N-vinylcaprolactam-co-vinylformamide) copolymers via RAFT polymerization followed by the hydrolysis to obtain primary amine groups, b) attachment of carboxyl-modified spiropyran mols. to polymer chains via coupling, and c) crosslinking of spiropyran-modified polymer chains in W/O miniemulsion to form microgels. Via this method, we successfully synthesized poly(N-vinylcaprolactam) microgels containing more than 10 mol% spiropyran. The reversible light responsiveness of the spiropyran-modified copolymers and microgels in aqueous solution, which originates from the spiropyran photoisomerization under irradiation with different wavelengths, was demonstrated by UV-Vis spectroscopy. Spiropyran-modified copolymers demonstrate shift of the lower critical solution temperature (LCST) due to the polarity change of spiropyran mols. under dark, UV and visible light. Surprisingly, dynamic light scattering (DLS) results show that the microgels based on the same copolymers are less affected by UV irradiation Microgels are swollen in darkness when spiropyran mols. are in the polar, merocyanine form, and collapse after irradiation with visible light, due to the transformation of spiropyran to the relatively nonpolar, closed spirocyclic form. In addition, the spiropyran-modified microgels exhibit reversible temperature responsiveness by presenting a volume phase transition in water from a swollen state to a collapsed state with increasing temperature and the transition temperature decreased compared to the pristine microgels due to the hydrophobicity of spiropyran units.

However, synthesis of light-responsive microgels with high loading of photoswitchable mols. is still very challenging. Herein we developed a new method to synthesize light and temperature dual-responsive spiropyran-modified poly(N-vinylcaprolactam) microgels. The novel and straightforward microgels synthesis route involved: a) synthesis of poly(N-vinylcaprolactam-co-vinylformamide) copolymers via RAFT polymerization followed by the hydrolysis to obtain primary amine groups, b) attachment of carboxyl-modified spiropyran mols. to polymer chains via coupling, and c) crosslinking of spiropyran-modified polymer chains in W/O miniemulsion to form microgels. Via this method, we successfully synthesized poly(N-vinylcaprolactam) microgels containing more than 10 mol% spiropyran. The reversible light responsiveness of the spiropyran-modified copolymers and microgels in aqueous solution, which originates from the spiropyran photoisomerization under irradiation with different wavelengths, was demonstrated by UV-Vis spectroscopy. Spiropyran-modified copolymers demonstrate shift of the lower critical solution temperature (LCST) due to the polarity change of spiropyran mols. under dark, UV and visible light. Surprisingly, dynamic light scattering (DLS) results show that the microgels based on the same copolymers are less affected by UV irradiation Microgels are swollen in darkness when spiropyran mols. are in the polar, merocyanine form, and collapse after irradiation with visible light, due to the transformation of spiropyran to the relatively nonpolar, closed spirocyclic form. In addition, the spiropyran-modified microgels exhibit reversible temperature responsiveness by presenting a volume phase transition in water from a swollen state to a collapsed state with increasing temperature and the transition temperature decreased compared to the pristine microgels due to the hydrophobicity of spiropyran units.

Hu, Chenghong;He, Xi;Han, Yunyan;Ye, Xiangyuan;Fan, Mingjin;Zhou, Feng;Liu, Weimin research published 《 High performance lubricants prepared from Naphthalene-1,4,5,8-Tetracarboxylic acid: Synthesis, physicochemical and Tribological properties》, the research content is summarized as follows. Ester oils (1,4,5,8-4Cn) were synthesized through esterification of naphthalene-1,4,5,8-tetracarboxylic acid with aliphatic alcs. The mol. structures were confirmed with 1H NMR, 13C NMR, FT-IR and elemental anal. Their KV, VI, FP, PP, oxidation and thermal stabilities, friction reducing and anti-wear performances were measured. The results demonstrate that the 1,4,5,8-4Cn have obviously higher thermal and oxidation stabilities than the existing esters DOS, PIS and Phe-3Ci8. They also have predominant tribol. behavior at both 50°C and 120°C. Analyzing from the results of ECR, QCM and XPS, it could be concluded that strongly and orderly physicochem. adsorption of the 1,4,5,8-4Cn mols. on the sliding surfaces is the critical factor for these oils to demonstrate excellent tribol. performance for steel contacts.
