Mathew, Bini;Ruiz, Pedro;Dutta, Shilpa;Entrekin, Jordan T.;Zhang, Sixue;Patel, Kaval D.;Simmons, Micah S.;Augelli-Szafran, Corinne E.;Cowell, Rita M.;Suto, Mark J. research published 《 Structure-activity relationship (SAR) studies of N-(3-methylpyridin-2-yl)-4-(pyridin-2-yl)thiazol-2-amine (SRI-22819) as NF-κB activators for the treatment of ALS》, the research content is summarized as follows. ALS is a rare type of progressive neurol. disease with unknown etiol. It results in the gradual degeneration and death of motor neurons responsible for controlling the voluntary muscles. Identification of mutations in the superoxide dismutase (SOD) 1 gene has been the most significant finding in ALS research. SOD1 abnormalities have been associated with both familial as well as sporadic ALS cases. SOD2 is a highly inducible SOD that performs in concurrence with SOD1 to detoxify ROS. Induction of SOD2 can be obtained through activation of NF-κBs. We previously reported that SRI-22819 increases NF-κB expression and activation in vitro, but it has poor ADME properties in general and has no oral bioavailability. Our initial studies were focused on direct modifications of SRI-22819. There were active compounds identified but no improvement in microsomal stability was observed In this context, we focused on making more significant structural changes in the core of the mol. Ataluren, an oxadiazole compound that promotes read-through and expression of dystrophin in patients with Duchenne muscular dystrophy, bears some structural similarity to SRI-22819. Thus, we synthesized a series of SRI-22819 and Ataluren (PTC124) hybrid compounds Several compounds from this series exhibited improved activity, microsomal stability and lower calculated polar surface area (PSA). This manuscript describes the synthesis and biol. evaluation of SRI-22819 analogs and its hybrid combination with Ataluren.

M.;Bahadur, Indra;Kumar, Vinod;Sherawat, Anjali;Singh, Prashant research published 《 Designed thiazolidines: an arsenal for the inhibition of nsP3 of CHIKV using molecular docking and MD simulations》, the research content is summarized as follows. Chikungunya virus belongs to alpha virus and its infection in humans causes fever, known as chikungunya fever. It is a sudden onset of fever and may affect humans badly. The mode of transmission to human occurs due to the biting of the mosquitoes. Till date, thousands of humans are affected from this virus throughout the world. As on date, no promising medicine or vaccine is available in the market to cure from this viral infection. Therefore, there is a need of promising candidate against the nsp3 of CHIKV. In the present work, a library of the compounds are designed based on the product obtained in a multi-component reaction. Then, the designed compounds are filtered based on binding energy against the nsp3 of CHIKV obtained using mol. docking. Further, to understand the interaction of nsp3 of CHIKV and screened compound, CMPD474, the mol. dynamics MD) simulations at different temperatures, i.e., 300, 325, 350, 375, and 400 K is performed. The binding or the formation of the complex is studied through different trajectories obtained from MD simulations. The accurate information for the binding energy is determined by performing MM-GBSA calculations and the best inhibition was observed at 300 K as the change in free energy for the formation of the complex is -7.0523 kcal/mol.Communicated by Ramaswamy H.

Mei, Lan;Cui, Xu;Wei, Juncheng;Duan, Qian;Li, Yanhui research published 《 Metal phthalocyanine-based conjugated microporous polymer/carbon nanotube composites as flexible electrodes for supercapacitors》, the research content is summarized as follows. Conjugated microporous polymers with active functional groups have attracted more and more attentions in energy conversion systems. However, their low elec. conductivity results in low capacitance, thus limiting their practical application. Herein, conjugated microporous polymer with triphenylamine aldehyde linked to metal phthalocyanines (MNC) is synthesized and then compounded with high-conductivity carbon nanotubes (CNTs) (denoted as CoNCCs) by vacuum filtration. Moreover, CoNCCs exhibit flexibility, which could be served as a self-standing and binder-free flexible electrode of supercapacitors. As a result, the optimized CoNCCs as the flexible electrode show high specific capacitance of 213.4 F g^-1 at 0.5 A g^-1. In addition, the higher capacity retention rate 85.3% can be retained after 1750 cycles at 20 A g^-1. The good electrochem. properties can be attributed to the synergistic effect and strong dual-phase interaction between MNC and CNTs. This work opens the way to develop high-performance and low environmental footprint organic electrode materials for SCs.

Designing and fabricating high-performance microwave absorption materials with efficient electromagnetic absorption and corrosion resistance becomes a serious and urgent concern. Herein, novel corrosion-resistant graphene-based carbon-coated iron (Fe@C) magnetic composite foam is fabricated via self-assembly of iron phthalocyanine/Fe₃O₄ (FePc hybrid) on the graphene skeletons under solvothermal conditions and then annealing at high temperature As a result, the rational construction of a hierarchical impedance gradient between graphene skeletons and Fe@C particles can facilitate the optimization in impedance matching and attenuation characteristic of the foam, realizing the efficient dissipation for incident electromagnetic waves. Addnl., the performance of electromagnetic absorption can be controllably regulated by optimizing annealing temperature and/or time. More importantly, the formation of a carbon-coated iron structure substantially improves the corrosion resistance of magnetic particles, endowing the composite foam with excellent stability and durability in microwave absorption performance.

Li, Siqi;Huang, Zhipeng;Liu, Huifang;Liu, Meijiang;Zhang, Chaofeng;Wang, Feng research published 《 Polar hydrogen species mediated nitroarenes selective reduction to anilines over an [FeMo]S_x catalyst》, the research content is summarized as follows. An efficient approach for the chemoselective synthesis of arylamines RNH₂ (R = 2-fluorophenyl, 2-acetyl-4,5-dimethoxyphenyl, 2-pyridyl, etc.) from nitroarenes RNO₂ and hydrazine over an iron-molybdenum sulfide catalyst ([FeMo]S_x) is presented. The heterogeneous hydrogen transfer reduction can be efficiently carried out at 30°C and provides anilines with 95-99% selectivities. The in situ gas product anal. demonstrates that [FeMo]Sx can catalyze the decomposition of N₂H₄ to H* species, not H₂. Combining with the kinetic anal. of the aniline generation rates from nitrobenzene and intermediates, the nitro group reduction to the nitroso group is confirmed to be the rate-determining step. The pos. slope of Hammett’s equation suggests that the critical intermediate in the rate-determining step is in the neg. state, which suggests that the active H* should be in polar states (H^δ- and H^δ+). These findings will provide a novel route for the synthesis of substituted anilines and broaden the application of MoS_x catalysts under mild conditions.
