Both viscoelastic and plastic properties were investigated on random copolymers of methylmethacrylate (MMA) and N-methyl-glutarimide (GIM) in the range 0-76 mol%. All the measurements were performed on samples quenched from the melt in order to break free from physical aging effects. Dynamic mechanical experiments were performed at very low deformation and temperatures ranging from -150C up to the glass transition temperature (Tg) region. Increase in GIM amount improves the thermomechanical stability of the copolymers, as revealed by the increase of both Tg and alpha relaxation temperature. In the beta relaxation region, the E? loss peak first decreases in amplitude with increasing GIM content and then broadens further and finally spreads out till the onset of the alpha peak at the largest GIM amounts. A quantitative analysis of the beta relaxation phenomena was performed by considering the loss compliance J? instead of the loss modulus E?. It turns out that in the low temperature range (-80C-0C) the mechanical damping associated with the MMA motions is stronger for MMA-GIM than for MMA-MMA linkages; in addition, the mechanical damping associated with the motions of the GIM units is very low. By contrast, in the high temperature range (30C to about 100C), the mechanical damping associated with the MMA motions drops with increasing GIM amount, whereas a significant damping coming from the GIM units is observed. These results suggest that the beta relaxation would mainly consist of MMA isolated motions at low temperature and of cooperative motions at higher temperature, involving the MMA units at GIM amounts lower or equal to 58 mol% and the GIM units at higher GIM content. The stress-strain curves were determined at low strain rate (2×10-3 s-1) and temperatures ranging from -120C to Tg. Analysis of the plastic deformation region shows that the yield stress decreases with increasing GIM amount at low temperatures. The opposite trend shows up on the high temperature side of the beta relaxation, where strain softening peaks at intermediate GIM amounts. As a plausible explanation, the cooperative beta motions, whenever they exist, are suspected to be responsible for the decrease of both yield stress and strain softening. These conclusions agree well with those of a previous study on methylmethacrylate-co-maleimide copolymers. They are also consistent with our earlier identification of the microdeformation mechanisms involved in the stretching of methylmethacrylate-co-N-methylglutarimide thin films.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1121-89-7 is helpful to your research. Application In Synthesis of Piperidine-2,6-dione

This paper deals with the mechanical properties (plastic deformation, micromechanism of deformation, fracture) of various amorphous polymers: poly(methyl methacrylate) and its maleimide and glutarimide copolymers, bisphenol A (and/or tetramethyl bisphenol A) polycarbonate, and aryl-aliphatic copolyamides. First, the required background on molecular characteristics, micromechanisms of deformation and fracture characterisation is recalled. Then, the results are discussed for each polymer series, considering information obtained on the motions involved in secondary transitions (mostly beta transitions) analysed in a previous paper. The importance of the cooperative motions occurring in the high temperature part of the transition is unambiguously pointed out. Furthermore, in glutarimide copolymers, as well as in aryl-aliphatic copolyamides, it is shown that the dependence of toughness on the entanglement density fails and only the consideration of cooperative a?transition motions can consistently account for the results. Finally, concerning the change of strain softening with increasing temperature, two opposite behaviours are observed for polymers in which beta transitions result, on the one hand from side-group motions (strain softening decreases) and on the other hand from certain main-chain units (strain softening increases). Two different mechanisms have been proposed, based on a softening of the polymer medium by a? transition motions associated with either an intramolecular cooperativity (in the first case), or an intermolecular cooperatively (in the second case) of these motions. Thus, combination of the results of the analysis of the relation of chemical structure to beta transition motions with the present conclusions yields a molecular description of the whole set of behaviours involved in the mechanical properties of amorphous polymers, till fracture.

Gastrointestinal stromal tumors (GISTs) are prototypes of stem cell factor receptor (c-KIT)-driven cancer. Two receptor tyrosine kinases, c-KIT and fms-tyrosine kinase (FLT3), are frequently mutated in acute myeloid leukemia (AML) patients, and these mutations are associated with poor prognosis. In this study, we discovered a multitargeted tyrosine kinase inhibitor, compound 15a, with potent inhibition against single or double mutations of c-KIT developed in GISTs. Moreover, crystal structure analysis revealed the unique binding mode of 15a with c-KIT and may elucidate its high potency in inhibiting c-KIT kinase activity. Compound 15a inhibited cell proliferation and induced apoptosis by targeting c-KIT in c-KIT-mutant GIST cell lines. The antitumor effects of 15a were also demonstrated in GIST430 and GIST patient-derived xenograft models. Further studies demonstrated that 15a inhibited the proliferation of c-KIT- and FLT3-driven AML cells in vitro and in vivo. The results of this study suggest that 15a may be a potential anticancer drug for the treatment of GISTs and AML.

Reactions of 5-nitrospiro[benzimidazole-2,1′-cyclohexane] 1,3-dioxide with aliphatic amines and sodium hydroxide resulted in removal of one N-oxide oxygen atom and formation of 4-alkylamino- or 4-hydroxy-substituted 5-nitrospiro[benzimidazole-2,1′-cyclohexane] 1-oxides, respectively. The title compound reacted with ammonia and methylamine in the presence of MnO2 with conservation of both N-oxide moieties, and the products were 4-amino- and 4-methylamino-5-nitrospiro[benzimidazole-2,1′-cyclohexane] 1,3-dioxides. The reactions with aromatic amines were accompanied by removal of both N-oxide oxygen atoms with formation of N-aryl-5-nitrospiro[benzimidazole-2,1′- cyclohexane]-4-amines. In the reactions of 5-nitrospiro- [benzimidazole-2,1′- cyclohexane] 1,3-dioxide with sodium azide and aromatic amine hydrochlorides nucleophilic replacement of the 5-nitro group by azido or arylamino occurred, in the first case both N-oxide fragments being conserved. The reactions with aromatic amine hydrochlorides afforded N-aryl-5-nitrospiro[benzimidazole- 2,1′-cyclohexan]-4-amine 1-oxides. Treatment of 5-nitrospiro[benzimidazole-2,1′- cyclohexane] 1,3-dioxide with sodium cyanide led to the formation of 5-oxo-3,5-dihydrospiro[benzimidazole-2,1′-cyclohexane]-4- carbonitrile 1-oxide.
