Zaouak, Amira;Chouchane, Habib;Jelassi, Haikel research published 《 Kinetic and mechanism investigation on the gamma irradiation induced degradation of quizalofop-p-ethyl》, the research content is summarized as follows. An efficient gamma radiolytic decomposition of one of the extensively used herbicides in the world quizalofo-p-Et (QPE) was explored under different exptl. conditions. Aqueous solutions of QPE were irradiated by gamma rays emitted by a Cobalt 60 source. QPE aqueous solutions were irradiated at doses of 0.5-3 kGy with 26.31 Gy min^-1 dose rate. Obtained results indicated that removal efficiency of 98.5% and 73% of QPE were obtained, resp., in absence and in presence of dissolved oxygen. Change of absorption spectra, pH effect and Total Organic Carbon (TOC) were carried out and studied. It was found that all absorption bands decreased with increasing irradiation dose and disappear totally after 3 kGy applied dose. Three pH conditions (pH = 10, pH = 6.2 and pH = 3) were applied in radiolytic degradation of QPE showing that the best removal efficiency has been found for neutral pH. Interestingly, the % TOC removal reaches 98% at 3 kGy indicated practically total mineralization. Furthermore, spectrophotometric analyses argued in favor of a pseudo-first-order kinetic of QPE degradation The resulting apparent rate constant value is approx. kapp = (0.012 ± 0.001) min^-1. Finally, several byproducts such as 6-chloroquinoxalin -2-ol, 2-(4-hydroxy-phenyoxy) propionate, 1,4-hydroquinone, quinone, 4-chlorobenzene-1,2diol and 1,2,4-benzenetriol were identified by gas chromatog.-mass spectrometry (GC/MS) evidencing that radiation process starting with the fragmentation of the mol. involving the hydroxyl radical, which is generated by the radiolysis of water. Based on the identification intermediates, a degradation mechanistic schema of QPE has been proposed.

Wang, Yuming;Li, Lijun;Fan, Jun;Dai, Yang;Jiang, Alan;Geng, Meiyu;Ai, Jing;Duan, Wenhu research published 《 Discovery of Potent Irreversible Pan-Fibroblast Growth Factor Receptor (FGFR) Inhibitors》, the research content is summarized as follows. Fibroblast growth factor receptors (FGFR1-4) are promising therapeutic targets in many cancers. With the resurgence of interest in irreversible inhibitors, efforts have been directed to the discovery of irreversible FGFR inhibitors. Currently, several selective irreversible inhibitors are being evaluated in clin. trials that could covalently target a conserved cysteine in the P-loop of FGFR. In this article, the authors used a structure-guided approach that is rationalized by a computer-aided simulation to discover the novel and irreversible pan-FGFR inhibitor, 9g ((S)-1-(3-(4-amino-5-(7-methoxy-5-methylbenzo[b]thien-2-yl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)pyrrolidin-1-yl)prop-2-en-1-one), which provided superior FGFR in vitro activities and decent selectivity over VEGFR2 (vascular endothelia growth factor receptor 2). In in vivo studies, 9g displayed clear antitumor activities in NCI-H1581 and SNU-16 xenograft mice models. Addnl., the diluting method confirmed the irreversible binding of 9g to FGFR.

Sanvee, Gerda M.;Bouitbir, Jamal;Krahenbuhl, Stephan research published 《 C2C12 myoblasts are more sensitive to the toxic effects of simvastatin than myotubes and show impaired proliferation and myotube formation》, the research content is summarized as follows. Statins reduce cardiovascular complications in patients with high LDL-cholesterol but are associated with myopathy. We compared the toxicity of simvastatin of C2C12 myoblasts and myotubes. Since myoblasts can proliferate and fuse to myotubes, myoblasts can be considered as satellite cells and myotubes as mature muscle fibers. Simvastatin increased plasma membrane permeability and decreased the cellular ATP content in both myoblasts and myotubes, but with a stronger effect on myoblasts. While insulin prevented cytotoxicity up to 8 h after addition of simvastatin to myotubes, prevention in myoblasts required simultaneous addition Mevalonate and geranylgeraniol prevented simvastatin-associated cytotoxicity in both myoblasts and myotubes. Simvastatin impaired the phosphorylation of the insulin receptor (IR β), Akt ser473 and S6rp, and increased phosphorylation of AMPK thr172 in both myotubes and myoblasts, which was prevented by insulin and mevalonate. Simvastatin impaired oxygen consumption and increased superoxide production by myoblasts and myotubes and induced apoptosis via cytochrome c release. In addition, simvastatin impaired proliferation and fusion of myoblasts to myotubes by inhibiting the expression of the nuclear transcription factor MyoD and of the metalloprotease ADAM-12. Decreased expression of the proliferation factor Ki-67 and of ADAM-12 were also observed in gastrocnemius of mice treated with simvastatin. In conclusion, myoblasts were more susceptible to the toxic effects of simvastatin and simvastatin impaired myoblast proliferation and myotube formation. Impaired muscle regeneration may represent a new mechanism of statin myotoxicity.

Sanvee, Gerda M.;Hitzfeld, Leonie;Bouitbir, Jamal;Krahenbuhl, Stephan research published 《 Article on mTORC2 is an important target for simvastatin-associated toxicity in C2C12 cells and mouse skeletal muscle – Roles of Rap1 geranylgeranylation and mitochondrial dysfunction》, the research content is summarized as follows. Statins decrease the serum LDL-cholesterol concentration and reduce the risk for cardiovascular diseases but can cause myopathy, which may be related to mTORC inhibition. In the current study, we investigated which mTORC is inhibited by simvastatin and by which mechanisms. In C2C12 myoblasts and myotubes and mouse gastrocnemius, simvastatin was cytotoxic and inhibited S6rp and Akt Ser473 phosphorylation, indicating inhibition of mTORC1 and mTORC2, resp. In contrast to simvastatin, the mTORC1 inhibitor rapamycin did not inhibit mTORC2 activity and was not cytotoxic. Like simvastatin, knock-down of Rictor, an essential component of mTORC2, impaired Akt Ser473 and S6rp phosphorylation and was cytotoxic for C2C12 myoblasts, suggesting that mTORC2 inhibition is an important myotoxic mechanism. The investigation of the mechanism of mTORC2 inhibition showed that simvastatin impaired Ras farnesylation, which was prevented by farnesol but without restoring mTORC2 activity. In comparison, Rap1 knock-down reduced mTORC2 activity and was cytotoxic for C2C12 myoblasts. Simvastatin impaired Rap1 geranylgeranylation and function, which was prevented by geranylgeraniol. In addition, simvastatin and the complex III inhibitor antimycin A caused mitochondrial superoxide accumulation and impaired the activity of mTORC2, which could partially be prevented by the antioxidant MitoTEMPO. In conclusion, mTORC2 inhibition is an important mechanism of simvastatin-induced myotoxicity. Simvastatin inhibits mTORC2 by impairing geranylgeranylation of Rap1 and by inducing mitochondrial dysfunction.
