Tang, Kuei C.;Maddox, Sean M.;Backus, Keriann M.;Raj, Monika research published 《 Tunable heteroaromatic azoline thioethers (HATs) for cysteine profiling》, the research content is summarized as follows. Here we report a new series of hydrolytically stable chemotype heteroaromatic azoline thioethers (HATs) to achieve highly selective, rapid, and efficient covalent labeling of cysteine under physiol. conditions. Although the resulting cysteine-azoline conjugate is stable, we highlight traceless decoupling of the conjugate to afford unmodified starting components in response to reducing conditions. We demonstrated that HAT probes reverse the reactivity of nucleophilic cysteine to electrophilic dehydroalanine (Dha) under mild basic conditions. We demonstrated the umpolung capability of HAT probes for the modification of cysteine on peptides and proteins with various nucleophiles. We demonstrated that HAT probes increase the mass sensitivity of the modified peptides and proteins by 100 fold as compared to the classical methods. Finally, we extended the application of HAT probes for specific modification of cysteines in a complex cell lysate mixture

Tang, Qi;Guo, Yilan;Meng, Liying;Chen, Xing research published 《 Chemical Tagging of Protein Lipoylation》, the research content is summarized as follows. Protein lipoylation is a post-translational modification of emerging importance in both prokaryotes and eukaryotes. However, labeling and large-scale profiling of protein lipoylation remain challenging. Here, we report the development of iLCL (iodoacetamide-assisted lipoate-cyclooctyne ligation), a chemoselective reaction that enables chem. tagging of protein lipoylation. We demonstrate that the cyclic disulfide of lipoamide but not linear disulfides can selectively react with iodoacetamide to produce sulfenic acid, which can be conjugated with cyclooctyne probes. iLCL enables tagging of lipoylated proteins for gel-based detection and cellular imaging. Furthermore, we apply iLCL for proteomic profiling of lipoylated proteins in both bacteria and mammalian cells. In addition to all of the eight known lipoylated proteins, we identified seven candidates for novel lipoylated proteins. The iLCL strategy should facilitate uncovering the biol. function of protein lipoylation.

Tani, Tomohiro;Sohma, Yudai;Tsuchimoto, Teruhisa research published 《 Zinc/Indium Bimetallic Lewis Acid Relay Catalysis for Dehydrogenative Silylation/Hydrosilylation Reaction of Terminal Alkynes with Bis(hydrosilane)s》, the research content is summarized as follows. When mixed with two different Lewis acid catalysts of Zn and In, terminal alkynes react with bis(hydrosilane)s to selectively provide 1,1-disilylalkenes from among several possible products, by way of a sequential dehydrogenative silylation/intramol. hydrosilylation reaction. Adding a pyridine base is crucial in this reaction; a switch as a catalyst of the Zn Lewis acid is turned on by forming a Zn-pyridine-base complex. A range of the 1,1-disilylalkenes can be obtained by a combination of aryl and aliphatic terminal alkynes plus aryl-, heteroaryl-, and naphthyl-tethered bis(hydrosilane)s. The 1,1-disilylalkene prepared here is available as a reagent for further transformations by using its C-Si or C:C bond. The former includes Hiyama cross-coupling, Bi-catalyzed ether formation, and iododesilylation; the latter includes double alkylation and epoxidation Mechanistic studies clarified the role of the two Lewis acids: the Zn-pyridine-base complex catalyzes the dehydrogenative silylation as a 1st stage, and, following on this, the In Lewis acid catalyzes the ring-closing hydrosilylation as a 2nd stage, thus leading to the 1,1-disilylalkene.

Tao, Xueqin;Long, Ran;Wu, Di;Hu, Yangguang;Qiu, Ganhua;Qi, Zeming;Li, Benxia;Jiang, Ruibin;Xiong, Yujie research published 《 Anchoring Positively Charged Pd Single Atoms in Ordered Porous Ceria to Boost Catalytic Activity and Stability in Suzuki Coupling Reactions》, the research content is summarized as follows. Single-atom (SA) catalysis bridging homogeneous and heterogeneous catalysis offers new opportunities for organic synthesis, but developing SA catalysts with high activity and stability is still a great challenge. A heterogeneous catalyst of Pd SAs anchored in 3D ordered macroporous ceria (Pd-SAs/3DOM-CeO₂) was developed through a facile template-assisted pyrolysis method. The high sp. surface area of 3DOM CeO₂ facilitates the heavily anchoring of Pd SAs, while the introduction of Pd atoms induces the generation of surface oxygen vacancies and prevents the grain growth of CeO₂ support. The Pd-SAs/3DOM-CeO₂ catalyst exhibits excellent activity toward Suzuki coupling reactions for a broad scope of substrates under ambient conditions, and the Pd SAs was stabilized in CeO₂ in long-term catalytic cycles without leaching or aggregating. Theor. calculations indicate that the CeO₂ supported Pd SAs can remarkably reduced the energy barriers of both transmetalation and reductive elimination steps for Suzuki coupling reactions. The strong metal-support interaction contributed to modulating the electronic state and maintaining the stability of Pd SA sites. The work demonstrated an effective strategy to design and synthesize stable single-atom catalysts as well as sheds new light on the origin for enhanced catalysis based on the strong metal-support interactions.

Anti-inflammatory properties have been attributed to latex proteins of the medicinal plant Calotropis procera. A mixture of cysteine peptidases (LPp2) from C. procera latex was investigated for control of inflammatory mediators and inflammation in a mouse model of Salmonella infection. LPp2 peptidase activity was confirmed by the BANA assay. Cytotoxicity assays were conducted with immortalized macrophages. Peritoneal macrophages (pMO) from Swiss mice were stimulated with lipopolysaccharide (LPS) in 96-well plates and then cultured with nontoxic concentrations of LPp2. Swiss mice i.v. received LPp2 (10 mg/kg) and then were challenged i.p. with virulent Salmonella enterica Ser. Typhimurium. LPp2 was not toxic at dosages lower than 62.2μg/mL. LPp2 treatments of pMO stimulated with LPS impaired mRNA expression of pro-inflammatory cytokines IL-1β, TNF-α IL-6 and IL-10. LPp2 increased the intracellular bacterial killing in infected pMO. Mice given LPp2 had a lower number of leukocytes in the peritoneal cavity in comparison to control groups 6 h after infection. The bacterial burden and histol. damage were widespread in target organs of mice receiving LPp2. We conclude that LPp2 contains peptidases with strong anti-inflammatory properties, which may render mice more susceptible to early disseminated infection caused by Salmonella.

Here, we described the design, by fragment merging and multiparameter optimization, of selective MMP-13 inhibitors that display an appropriate balance of potency and physicochem. properties to qualify as tool compounds suitable for in vivo testing. Optimization of potency was guided by structure-based insights, specifically to replace an ester moiety and introduce polar directional hydrogen bonding interactions in the core of the mol. By introducing polar enthalpic interactions in this series of inhibitors, the overall beneficial physicochem. properties were maintained. These physicochem. properties translated to excellent drug-like properties beyond potency.

We report on the first cobalt corrole that effectively mediates the homogeneous hydrogenation of structurally diverse nitroarenes to afford the corresponding amines. The given catalyst is easily assembled prior to use from 4-tert-butylbenzaldehyde and pyrrole followed by metalation of the resulting corrole macrocycle with cobalt(II) acetate. The thus-prepared complex is self-contained in that the hydrogenation protocol is free from the requirement for adding any auxiliary reagent to elicit the catalytic activity of the applied metal complex. Moreover, a containment system is not required for the assembly of the hydrogenation reaction set-up as both the autoclave and the reaction vessels are readily charged under a regular laboratory atm.

O-O bond formation with Ru(bda)L2-type catalysts is well-known to proceed through a bimol. reaction pathway, limiting the potential application of these catalysts at low concentrations Herein, we achieved high efficiencies with mononuclear catalysts, with TOFs of 460±32 s-1 at high catalyst loading and 31±3 s-1 at only 1 μM catalyst concentration, by simple structural considerations on the axial ligands. Kinetic and DFT studies show that introduction of an off-set in the interaction between the two catalytic units reduces the kinetic barrier of the second-order O-O bond formation, maintaining high catalytic activity even at low catalyst concentrations The results herein furthermore suggest that π-π interactions may only play a minor role in the observed catalytic activity, and that asymmetry can also rationalize high activity observed for Ru(bda)(isoq)2 type catalysts and offer inspiration to overcome the limitations of 2nd order catalysis.

Peptides are regarded as promising next-generation therapeutics. However, an anal. of over 1000 bioactive peptide candidates suggests that many have underdeveloped affinities and could benefit from cyclization using a bridging linker sequence. Until now, the primary focus has been on the use of inert peptide linkers. Here, we show that affinity can be significantly improved by enriching the linker with functional amino acids. We engineered a peptide inhibitor of PCSK9, a target for clin. management of hypercholesterolemia, to demonstrate this concept. Cyclization linker optimization from library screening produced a cyclic peptide with ~100-fold improved activity over the parent peptide and efficiently restored low-d. lipoprotein (LDL) receptor levels and cleared extracellular LDL. The linker forms favorable interactions with PCSK9 as evidenced by thermodn., structure-activity relationship (SAR), NMR, and mol. dynamics (MD) studies. This PCSK9 inhibitor is one of many peptides that could benefit from bioactive cyclization, a strategy that is amenable to broad application in pharmaceutical design.
