Hirano, Tomohiro;Kamiike, Ryota;Yuki, Takumi;Matsumoto, Daishi;Ute, Koichi research published 《 Determination of monomer reactivity ratios from a single sample using multivariate analysis of the ¹H NMR spectra of poly[(methyl methacrylate)-co-(benzyl methacrylate)]》, the research content is summarized as follows. Copolymers of Me methacrylate (MMA) and benzyl methacrylate (BnMA) were prepared by conventional radical copolymerization in toluene at 70°C. The ¹H NMR (NMR) spectra of these copolymers were measured in various solvents at different temperatures The signals of the methoxy protons in the MMA units and the benzyl protons in the BnMA units showed splitting mainly because of the triad monomer sequences when the temperature was increased to 150°C in deuterated DMSO. However, the splitting was not sufficient to determine the molar ratios of the triad sequences. Therefore, multivariate anal. was applied to the ¹H NMR spectra of copolymers with various chem. compositions Principal component anal. successfully extracted information on the polymer microstructures. Partial least-squares (PLS) regression successfully predicted the mole fractions of the diad monomer sequences. Then, the fractions of the diad sequences in an unknown sample prepared in benzene at 60°C were predicted using PLS regression to determine the monomer reactivity ratios. Thus, the monomer reactivity ratios were successfully determined from a single sample using multivariate anal. of the ¹H NMR spectra of copolymers of MMA and BnMA.

We describe the synthesis of triazole-containing carboline derivatives and their utility as bromodomain and extra-terminal (BET) inhibitors. A convergent synthetic route permitted the detailed investigation of deuteration and fluorination strategies to reduce clearance while maintaining a favorable in vitro profile. This work led to the identification of a potent BET inhibitor, 2-{8-fluoro-3-[4-(²H₃)methyl-1-methyl-1H-1,2,3-triazol-5-yl]-5-[(S)-(oxan-4-yl)(phenyl)methyl]-5H-pyrido[3,2-b]indol-7-yl}propan-2-ol (15), which demonstrated reduced clearance and an improved pharmacokinetic (PK) profile across preclin. species. Importantly, no major metabolite was observed when 15 was incubated with human hepatocytes (hHEP) for 2 h. This study culminated with the evaluation of 15 in a mouse triple-neg. breast cancer (TNBC) tumor model where it demonstrated robust efficacy at low doses.

Herbort, James H.;Bednar, Taylor N.;Chen, Andrew D.;RajanBabu, T. V.;Nagib, David A. research published 《 γ C-H Functionalization of Amines via Triple H-Atom Transfer of a Vinyl Sulfonyl Radical Chaperone》, the research content is summarized as follows. A selective, remote desaturation has been developed to rapidly access homoallyl amines from their aliphatic precursors. The strategy employs a triple H-atom transfer (HAT) cascade, entailing (i) cobalt-catalyzed metal-HAT (MHAT), (ii) carbon-to-carbon 1,6-HAT, and (iii) Co-H regeneration via MHAT. A new class of sulfonyl radical chaperone (to rapidly access and direct remote, radical reactivity) enables remote desaturation of diverse amines, amino acids, and peptides with excellent site-, chemo-, and regioselectivity. The key, enabling C-to-C HAT step in this cascade was computationally designed to satisfy both thermodn. (bond strength) and kinetic (polarity) requirements, and it has been probed via regioselectivity, isomerization, and competition experiments We have also interrupted this radical transfer dehydrogenation to achieve γ-selective C-Cl, C-CN, and C-N bond formations.

Herbort, James H.;Lalisse, Remy F.;Hadad, Christopher M.;RajanBabu, T. V. research published 《 Cationic Co(I) Catalysts for Regiodivergent Hydroalkenylation of 1,6-Enynes: An Uncommon cis-α-C-H Activation Leads to Z-Selective Coupling of Acrylates》, the research content is summarized as follows. Two intermol. hydroalkenylation reactions of 1,6-enynes N(R)(CH²CH=CH²)CH²CCR¹ (R = -N(Ts)-, -C(COOEt)₂-, -O-, -N(Boc)-; R¹ = 4-fluorophenyl, thiophen-3-yl, prop-1-en-2-yl, etc.) are presented which yield substituted 5-membered carbo- and -heterocycles I (R = -N(Ts)-, -C(COOEt)²-; R² = H, Me; R³ = H, Me, n-Bu). This reactivity is enabled by a cationic bis-diphenylphosphinopropane (DPPP)CoI species which forms a cobaltacyclopentene intermediate by oxidative cyclization of the enyne. This key species interacts with alkenes in distinct fashion, depending on the identity of the coupling partner to give regiodivergent products I. Simple alkenes undergo insertion reactions to furnish 1,3-dienes whereby one of the alkenes is tetrasubstituted. The acerylates R⁴CH=C(R⁵)C(O)OR⁶ (R⁴ = H, Me, OMe; R⁵ = H, Me; R⁶ = Me, Bn, Cy, t-Bu) were employed as coupling partners, and the site of intermol. C-C formation shifts from the alkyne to the alkene motif of the enyne, yielding Z-substituted-acrylate derivatives II. Computational studies provide support for the exptl. observations and show that the turnover-limiting steps in both reactions are the interactions of the alkenes with the cobaltacyclopentene intermediate via either a 1,2-insertion in the case of ethylene, or an unexpected α-C-H activation in the case of most acrylates. Thus, the H syn to the ester is activated through the coordination of the acrylate carbonyl to the cobaltacycle intermediate, which explains the uncommon Z-selectivity and regiodivergence. Variable time normalization anal. (VTNA) of the kinetic data reveals a dependence upon the concentration of cobalt, acrylate, and activator. A KIE of 2.1 was observed with Me methacrylate in sep. flask experiments, indicating that C-H cleavage is the turnover-limiting step in the catalytic cycle. Lastly, a Hammett study of aryl-substituted enynes yields a ρ value of -0.4, indicating that more electron-rich substituents accelerate the rate of the reaction.

He, Zhangxu;Jiao, Haomiao;An, Qi;Zhang, Xin;Dan, Zengyangzong;Xu, Jiale;Liu, Hongmin;Ma, Liying;Zhao, Wen research published 《 Discovery of novel 4-phenylquinazoline-based BRD4 inhibitors for cardiac fibrosis》, the research content is summarized as follows. Bromodomain containing protein 4 (BRD4), as an epigenetic reader, can specifically bind to the acetyl lysine residues of histones and has emerged as an attractive therapeutic target for various diseases, including cancer, cardiac remodeling and heart failure. Herein, we described the discovery of hit 5 bearing 4-phenylquinazoline skeleton through a high-throughput virtual screen using 2,003,400 compound library (enamine). Then, structure-activity relationship (SAR) study was performed and 47 new 4-phenylquinazoline derivatives toward BRD4 were further designed, synthesized and evaluated, using HTRF assay set up in our laboratory Eventually, we identified compound C-34, which possessed better pharmacokinetic and physicochem. properties as well as lower cytotoxicity against NRCF and NRCM cells, compared to the pos. control JQ1. Using computer-based mol. docking and cellular thermal shift assay, we further verified that C-34 could target BRD4 at mol. and cellular levels. Furthermore, treatment with C-34 effectively alleviated fibroblast activation in vitro and cardiac fibrosis in vivo, which was correlated with the decreased expression of BRD4 downstream target c-MYC as well as the depressed TGF-β1/Smad2/3 signaling pathway. Taken together, our findings indicate that novel BRD4 inhibitor C-34 tethering a 4-phenylquinazoline scaffold can serve as a lead compound for further development to treat fibrotic cardiovascular disease.

Me tetrahydrofuran-2-carboxylate (MeTHFC) and its derivatives are widely used as raw materials and intermediates in chem. industries. An efficient and clean method for the synthesis of MeTHFC was proposed, which included the oxidative esterification of biomass-based furfural into Me furoate and the selective hydrogenation of Me furoate into MeTHFC. The hydrogenation of biomass-derived Me furoate was investigated on Ni-SiO₂ catalysts with the different Ni contents prepared by a deposition-precipitation method. The Ni-SiO₂ catalyst with 50 wt% Ni loading displayed an excellent performance with a high conversion under mild reaction conditions. Moreover, this catalyst presented a slight decrease of conversion, probably due to the increasing Ni⁰ particle size and Ni leaching during 200 h time-onstream. Characterization results revealed that the formation of Ni phyllosilicates was responsible for high Ni dispersion and sp. surface area in the Ni-SiO₂ catalysts, which facilitate their hydrogenation performance.
