Du, Xiaoyong;Xiao, Ye;Yang, Yuhong;Duan, Ya-Nan;Li, Fangfang;Hu, Qi;Chung, Lung Wa;Chen, Gen-Qiang;Zhang, Xumu research published 《 Enantioselective Hydrogenation of Tetrasubstituted α,β-Unsaturated Carboxylic Acids Enabled by Cobalt(II) Catalysis: Scope and Mechanistic Insights》, the research content is summarized as follows. Chiral carboxylic acids are important compounds because of their prevalence in pharmaceuticals, natural products and agrochems. Asym. hydrogenation of α,β-unsaturated carboxylic acids has been widely recognized as one of the most efficient synthetic approaches to afford such compounds Although related asym. hydrogenation of di- and trisubstituted unsaturated acids with noble metals is well established, asym. hydrogenation of challenging tetrasubstituted α,β-unsaturated carboxylic acids is rarely reported. We demonstrate enantioselective hydrogenation of cyclic (2-aryl-1-cycloalkene-1-carboxylic acids) and acyclic (α-isopropylidenearylacetic acids) tetrasubstituted α,β-unsaturated carboxylic acids via cobalt(II) catalysis. This protocol showed broad substrate scope and gave chiral carboxylic acids in good yields with excellent enantiocontrol (up to 98% yield and 99% ee). Combined exptl. and computational mechanistic studies support a Co^II catalytic cycle involving migratory insertion and σ-bond metathesis processes. DFT calculations reveal that enantioselectivity may originate from the steric effect between the Ph groups of the ligand and the substrate.

Du, Bingnan;Chan, Chun-Ming;Lee, Pui-Yiu;Cheung, Leong-Hung;Xu, Xin;Lin, Zhenyang;Yu, Wing-Yiu research published 《 2,2-difluorovinyl benzoates for diverse synthesis of gem-difluoroenol ethers by Ni-catalyzed cross-coupling reactions》, the research content is summarized as follows. Structurally diverse 2,2-difluorovinyl benzoates (BzO-DFs) RC(O)₂C(R¹)=C(F₂) (R = C₆H₅, 4-ClC₆H₄, 1-adamantyl, etc.; R¹ = OC₂H₅, OCH₂C₆H₅, 2-CH₃C₆H₄, etc.) and RC(O)₂C(R²)=C(F₂) (R² = 4-(C(CH₃)₃)C₆H₄, 2-CH₃C₆H₄, 4-CH₃OCC₆H₄) developed as versatile building blocks for modular synthesis of gem-difluoroenol ethers RC(R¹)=C(F₂) and R³C(R¹)=C(F)₂ (R³ = C₆H₅, 4-ClC₆H₄, 2-naphthyl, etc.) (44 examples) and gem-difluoroalkenes RC(R¹)=C(F₂) (R¹ = 4-CH₃OC₆H₄, C(CH₃)₃) (2 examples) by Ni-catalyzed cross coupling reactions have been described. Diverse BzO-DFs derivatives bearing sensitive functional groups (e.g., C = C, TMS, strained carbocycles) are readily prepared from their bromodifluoroacetates R¹C(O)C(Br)F₂ and bromodifluoroketones precursors using metallic zinc as reductant. With Ni(COD)₂ and dppf [1,1′-bis(diphenylphosphino)ferrocene] as catalyst, reactions of BzO-DFs with arylboronic acids R³B(OH)₂ and arylmagnesium reagents R²MgBr afforded the desired gem-difluoroenol ethers and gem-difluoroalkenes in good yields. The Ni-catalyzed coupling reactions features highly regioselective C(vinyl)-O(benzoate) bond activation of the BzO-DFs. Results from control experiments and DFT calculations are consistent with a mechanism involving initial oxidative addition of the BzO-DFs by the Ni(0) complex. By virtue of diversity of the BzO-DFs and excellent functional group tolerance, this method is amenable to late-stage functionalization of multifunctionalized bioactive mols.

Doty, Anna C.;Wilson, A. Dan;Forse, Lisa B.;Risch, Thomas S. research published 《 Biomarker Metabolites Discriminate between Physiological States of Field, Cave and White-nose Syndrome Diseased Bats》, the research content is summarized as follows. Anal. of volatile organic compound (VOC) emissions using electronic-nose (e-nose) devices has shown promise for early detection of white-nose syndrome (WNS) in bats. Tricolored bats, Perimyotis subflavus, from three sep. sampling groups defined by environmental conditions, levels of phys. activity, and WNS-disease status were captured temporarily for collection of VOC emissions to determine relationships between these combinations of factors and physiol. states, Pseudogymnoascus destructans (Pd)-infection status, and metabolic conditions. Physiol. active (non-torpid) healthy individuals were captured outside of caves in Arkansas and Louisiana. In addition, healthy and WNS-diseased torpid bats were sampled within caves in Arkansas. Whole-body VOC emissions from bats were collected using portable air-collection and sampling-chamber devices in tandem. Electronic aroma-detection data using three-dimensional Principal Component Anal. provided strong evidence that the three groups of bats had significantly different e-nose aroma signatures, indicative of different VOC profiles. This was confirmed by differences in peak numbers, peak areas, and tentative chem. identities indicated by chromatograms from dual-column GC-analyses. The numbers and quantities of VOCs present in whole-body emissions from physiol. active healthy field bats were significantly greater than those of torpid healthy and diseased cave bats. Specific VOCs were identified as chem. biomarkers of healthy and diseased states, environmental conditions (outside and inside of caves), and levels of physiol. activity. These results suggest that GC/E-nose dual-technologies based on VOC-detection and analyses of physiol. states, provide noninvasive alternative means for early assessments of Pd-infection, WNS-disease status, and other physiol. states.

The possibility to design rational carbon dots surface functionalization for specific anal. and bioanal. applications is hindered by the lack of a full knowledge of the surface chem. features driving fluorescent properties. In this model study, we have synthesized four different peptides, three of which are isobaric and not distinguishable by common MSMS experiments After having characterized the peptides conformations by CD analyses, we have covalently bonded all four peptides to carbon dots by using different exptl. procedures, which produce different functional groups on the carbon dots surface. The peptide orientations obtained on the differently functionalized surface of the nanoparticles were different and produced different fluorescent responses. The reported results indicate the possibility to design amino and carboxyl enriched surface carbon dots to answer specific chem. requirements, paving the way for the use of these nanoparticles as a versatile and useful new chem. and biochem. tool.

Dennison, Sarah R.;Reddy, Subrayal M.;Morton, Leslie H. G.;Harris, Frederick;Badiani, Kamal;Phoenix, David A. research published 《 PEGylation enhances the antibacterial and therapeutic potential of amphibian host defence peptides》, the research content is summarized as follows. Aurein 2.1, aurein 2.6 and aurein 3.1 are amphibian host defense peptides that kill bacteria via the use of lytic amphiphilic α-helical structures. The C-terminal PEGylation of these peptides led to decreased antibacterial activity (Min. Lethal Concentration (MLCs) ↓ circa one and a half to threefold), reduced levels of amphiphilic α-helical structure in solvents (α-helicity ↓ circa 15.0%) and lower surface activity (Δπ ↓ > 1.5 mN m^-1). This PEGylation of aureins also led to decreased levels of amphiphilic α-helical structure in the presence of anionic membranes and zwitterionic membranes (α-helicity↓ > 10.0%) as well as reduced levels of penetration (Δπ ↓ > 3.0 mN m^-1) and lysis (lysis ↓ > 10.0%) of these membranes. Based on these data, it was proposed that the antibacterial action of PEGylated aureins involved the adoption of α-helical structures that promote the lysis of bacterial membranes, but with lower efficacy than their native counterparts. However, PEGylation also reduced the haemolytic activity of native aureins to negligible levels (haemolysis ↓ from circa 10% to 3% or less) and improved their relative therapeutic indexes (RTIs ↑ circa three to sixfold). Based on these data, it is proposed that PEGylated aureins possess the potential for therapeutic development; for example, to combat infections due to multi-drug resistant strains of S. aureus, designated as high priority by the World Health Organization.

Demir, Murat;Altindag, Fikret research published 《 Sinapic acid ameliorates cisplatin-induced disruptions in testicular steroidogenesis and spermatogenesis by modulating androgen receptor, proliferating cell nuclear antigen and apoptosis in male rats》, the research content is summarized as follows. The chemotherapeutic cisplatin, which is widely used in many cancer types, causes testicular toxicity. Sinapic acid has many therapeutic effects such as antioxidant, anti-inflammatory and antihyperglycemic. This study aimed to investigate the improving effects of sinapic acid in cisplatin-induced testicular toxicity. Twenty-eight rats were distributed into 4 groups. Control group: saline was applied i.p. Cisplatin group: A single dose of 7 mg/kg of cisplatin was injected into rats. Cisplatin +Sinapic acid group: 3 days after a single dose of 7 mg/kg cisplatin was injected, 25 mg/kg of sinapic acid was given for 7 days. Sinapic acid group: rats were received 25 mg/kg/day of sinapic acid. Numerical d. of spermatogonium, Leydig and volume d. of germinal epithelial were calculated Caspase-3, Bcl-2, AR and PCNA expressions in testis were evaluated and testosterone and LH levels were measured. Cisplatin application decreased the numerical d. of spermatogonium and Leydig, volume d. of germinal, epididymal sperm count, testosterone, LH and the expressions of Bcl-2, AR and PCNA in testis. However, sinapic acid treatment significantly restored the parameters of our study. The results of the present study revealed that cisplatin can cause male reproductive toxicity and sinapic acid can have improving effects against cisplatin-induced male reproductive toxicity.
