10). These complexes are slightly different from 1, which has a distorted-square-pyramidal geometry (τ5 = 0.25) with a coordinated chloride anion. UV-vis spectra of 2 and 3 in MeCN show a spectral pattern characteristic of a square-planar Ni(II) complex. These spectra are slightly different from the unique spectrum of 1, which is typical of an axially coordinating Ni(II) species as a result of having a Cl- anion at the apical position. Electrocatalytic hydrogen generation promoted by these three Ni(II) complexes (1.0 mmol) demonstrates an increase in the catalytic current induced by stepwise addition of HOAc (pKa = 22.3 in MeCN) as a proton source. The complexes demonstrate turnover frequencies (TOF) of 3800 s-1 for 1, 5400 s-1 for 2, and 8800 s-1 for 3 in MeCN (3 mL) containing 0.1 M [n-Bu4N](ClO4) in the presence of HOAc (145 equiv) at overpotentials of ca. 530, 490, and 430 mV, respectively.Lymph nodes are the main sites for immune activation and surveillance. Effective delivery of immunomodulators into lymph nodes to trigger antitumor immunity is essential for cancer treatment. read more Here, we propose a lymph node delivery strategy to modulate the immune response by activating cytotoxic T lymphocytes (CTLs) and natural killer (NK) cells simultaneously. Novel pH/redox dual-sensitive micelles were prepared using poly(l-histidine)-poly(ethylene glycol) (PLH-PEG) as a skeleton, which can effectively deliver immunomodulators to the lymph nodes due to their suitable particle size. At 48 h after subcutaneous injection, the accumulation efficiency in lymph nodes increased 8.12-fold compared with the control group. Subsequently, Trp2/CpG-coloaded pH/redox dual-sensitive micelles (Trp2/CpG-NPs) acted on antigen-presenting cells, fully promoting CTL activation through dendritic cell antigen cross-presentation and macrophage repolarization. IL-15-loaded pH/redox dual-sensitive micelles (IL-15-NPs) were developed to activate the killing effect of NK cells by interacting with IL-15 receptors. In the tumor-bearing mice model, this lymph node delivery strategy showed significant antitumor efficiency and the tumor inhibition rate reached 93.76%. Meanwhile, the infiltration of CTLs and NK cells in tumor tissues increased, and the immunosuppressive microenvironment was relieved by the repolarization of macrophages from M2-type to M1-type. Overall, this study highlighted the potential of the lymph node delivery strategy for cancer immunotherapy.A three-liquid-phase system (TLPS) was developed and used as a novel enzymatic one-pot multistep reaction (EOMR) system. In this system, lipase and phospholipase were enriched in a single liquid phase with a high recovery (ca. 98%) and then used for the simultaneous catalysis of mutually inhibiting and interfering reactions (hydrolysis of phospholipids and glyceride in crude oil). A novel emulsion containing the two dispersed droplets (W2/O/W2 and W1/W2 emulsion structures) could be the key reason for this phenomenon because the emulsion system not only provided a new catalytic interface but also relieved the product inhibition. As a result, the content of free fatty acid (main hydrolysate of the glyceride) and the removal of phospholipid from the crude oil could be increased to 96 and 95%, respectively, within 1 h. The product obtained from the EOMR was directly used in the production of biodiesel via enzymatic esterification, and the content of fatty acid methanol ester could be increased to 93% within 2 h. Furthermore, the enzymes in the middle phase could also be reused, at least for eight rounds without significant loss in catalytic efficiency. Therefore, the TLPS could be considered as an ideal catalytic platform for the EOMR.While thousands of environmental metagenomes have been mined for the presence of novel biosynthetic gene clusters, such computational predictions do not provide evidence of their in vivo biosynthetic functionality. Using fluorescent in situ enzyme assay targeting carrier proteins common to polyketide (PKS) and nonribosomal peptide synthetases (NRPS), we applied fluorescence-activated cell sorting to tunicate microbiome to enrich for microbes with active secondary metabolic capabilities. Single-cell genomics uncovered the genetic basis for a wide biosynthetic diversity in the enzyme-active cells and revealed a member of marine Oceanospirillales harboring a novel NRPS gene cluster with high similarity to phylogenetically distant marine and terrestrial bacteria. Interestingly, this synthase belongs to a larger class of siderophore biosynthetic gene clusters commonly associated with pestilence and disease. This demonstrates activity-guided single-cell genomics as a tool to guide novel biosynthetic discovery.We introduce a highly efficient ligation system based on a visible light-induced rearrangement affording a thiophenol which rapidly undergoes thiol-Michael additions. Unlike conventional light-triggered thiol-ene/yne systems, which rely on the use of photocaged bases/nucleophiles, (organo)-photo catalysts, or radical photoinitiators, our system provides a light-induced reaction in the absence of any additives. The ligation is self-catalyzed via the pyridine mediated deprotonation of the photochemically generated thiophenol. Subsequently, the thiol-Michael reaction between the thiophenol anion and electron deficient alkynes/alkenes proceeds additive-free. Hereby, the underlying photoinduced rearrangement of o-thiopyrinidylbenzaldehyde (oTPyB) generating the free thiol is described for the first time. We studied the influence of various reactions conditions as well as solvents and substrates. We exemplify our findings in a polymer end group modification and obtained macromolecules with excellent end group fidelity.With the aim of completing our previous efforts devoted to local and Rydberg transitions in organic compounds, we provide a series of highly accurate vertical transition energies for intramolecular charge-transfer transitions occurring in (π-conjugated) molecular compounds. To this end, we apply a composite protocol consisting of linear-response CCSDT excitation energies determined with Dunning's double-ζ basis set corrected by CC3/CCSDT-3 energies obtained with the corresponding triple-ζ basis. Further basis set corrections (up to aug-cc-pVQZ) are obtained at the CCSD and CC2 levels. We report 30 transitions obtained in 17 compounds (aminobenzonitrile, aniline, azulene, benzonitrile, benzothiadiazole, dimethylaminobenzonitrile, dimethylaniline, dipeptide, β-dipeptide, hydrogen chloride, nitroaniline, nitrobenzene, nitrodimethylaniline, nitropyridine N-oxide, N-phenylpyrrole, phthalazine, and quinoxaline]. These reference values are then used to benchmark a series of wave functions [CIS(D), SOPPA, RPA(D), EOM-MP2, CC2, CCSD, CCSD(T)(a)*, CCSDR(3), CCSDT-3, CC3, ADC(2), ADC(3), and ADC(2.
