We designed and synthesized a tri-(2-picolyl) amine (TPA) functionalized triarylborane, 1-(6-(4-(dimesitylboryl)phenyl)pyridin-2-yl)-N,N-bis(pyridin-2-ylmethyl)methanamine (PB2). The photophys. properties of PB2 were thoroughly explored. Moreover, PB2 can capture CN– and F– in aqueous solution through strong chelation induced by the synergy of a boron atom and metal ion gripped by TPA to display entirely different fluorogenic responses such as fluorescence enhancement for CN– and fluorescence quenching for F–. The results of TOF-MS-EI anal. and theor. calculations indicate that the complexing of PB2 with CN– formed a 2-to-2 adduct with a stabilized configuration, resulting in strong emission. The complexing of PB2 with F– formed a 1-to-1 adduct with a loose configuration, resulting in weak emission. In pure water, the detection limit of PB2 for CN– is 0.79 μM, and in H2O/THF (1:9 volume/volume) system, the detection limits of PB2 for CN– and F– can reach 0.39 and 2.12 μM, resp., indicating its potential application for effective detection and discrimination of CN– and F–.

Zhang, Ya-Wen;Bai, Sha;Wang, Yao-Yu;Han, Ying-Feng research published 《 A Strategy for the Construction of Triply Interlocked Organometallic Cages by Rational Design of Poly-NHC Precursors》, the research content is summarized as follows. Three-dimensional (3D) triply interlocked catenanes are a family of chem. topologies that consist of two identical, mech. interlocked coordination cage components with intriguingly complex structures. Although only a few successful constructions of 3-dimensional interlocked catenanes were achieved to date via metal-mediated assembly, these complex structures have thus far only been targeted by metal-N/O coordination techniques. Here, taking advantage of rational ligand design, the authors report the efficient construction of 3-dimensional triply interlocked [2]catenanes [Ag3L2]2, wherein the metal ions exclusively form bonds to N-heterocyclic carbene (NHC) units, and their subsequent transmetalation to the corresponding [Au3L2]2 Au analogs. The formation and transmetalation reactions proceed under mild conditions and are generally applicable. Characterization techniques were applied to confirm the formation and structure of the desired 3-dimensional triply interlocked architectures: multinuclear NMR spectroscopy, ESI-MS, and single-crystal x-ray diffraction anal. The solid-state structure of [Ag3(1a)2]2(PF6)6 unambiguously confirms the existence of a 3-dimensional catenane that consists of two identical, mech. interlocked trinuclear hexacarbene cage components. The interlocking of two 3-dimensional cages into a [2]catenane is driven by the efficient π···π stacking of triazine-triazine stacks with cooperative interactions between imidazo[1,5-a]pyridine subunits. Notably, the triply interlocked organometallic cages exhibit good stability toward various organic solvents, concentrations, and temperatures, and no disassembly occurred in the presence of coronene or pyrene. The future construction of mech. interlocked architectures using metal-carbene bonds rather than metal-N bonds may provide assemblies with interesting properties for as-yet-unimagined applications in fields such as sensors and mol. elec. conductors.

The imidazo[1,5-a]pyridinium salts H3-L(PF6)3 (L= 4a–4c) were treated with 1.5 equiv of Ag2O to yield the trinuclear AgI hexacarbene cages [Ag3(L)2](PF6)3 (L= 4a–4c), in which three AgI are sandwiched between the two tricarbene ligands. The silver(I) complexes [Ag3(L)2](PF6)3 underwent a facile transmetalation reaction in the presence of 3 equiv of [AuCl(tht)] (tht=tetrahydrothiophene) to furnish the trinuclear AuI cylinder-like cages [Au3(L)2](PF6)3 (L= 4a–4c) without destruction of the metallosupramol. structure. The new hexacarbene assemblies feature a large cavity that can easily accommodate a mol. of DMSO as mol. guest.

Zhang, Yao;Ma, Jiawei;Chen, Jian;Meng, Lingpu;Liang, Yong;Zhu, Shaolin research published 《 A relay catalysis strategy for enantioselective nickel-catalyzed migratory hydroarylation forming chiral α-aryl alkylboronates》, the research content is summarized as follows. Ligand-controlled reactivity plays an important role in transition-metal catalysis, enabling a vast number of efficient transformations to be discovered and developed. However, a single ligand is generally used to promote all steps of the catalytic cycle (e.g., oxidative addition, reductive elimination), a requirement that makes ligand design challenging and limits its generality, especially in relay asym. transformations. Herein it is hypothesized that multiple ligands with a metal center might be used to sequentially promote multiple catalytic steps, thereby combining complementary catalytic reactivities through a simple combination of simple ligands. With this relay catalysis strategy (L/L*), the first highly regio- and enantioselective remote hydroarylation process is reported. By synergistic combination of a known chain-walking ligand and a simple asym. cross-coupling ligand with the nickel catalyst, enantioenriched α-aryl alkylboronates could be rapidly obtained as versatile synthetic intermediates through this formal asym. remote C(sp3)-H arylation process.

Energy transfer plays a special role in photocatalysis by utilizing the potential energy of the excited state through indirect excitation, in which a photosensitizer determines the thermodn. feasibility of the reaction. Bioinspired by the energy-transfer ability of natural product Cercosporin, here we developed a green and highly efficient organic photosensitizer HiBRCP (hexaisobutyryl reduced Cercosporin) through structural modification of Cercosporin. After structural manipulation, its triplet energy was greatly improved, and then, it could markedly promote the efficient geometrical isomerization of alkenes from the E-isomer to the Z-isomer. Moreover, it was also effective for energy-transfer-mediated organometallic catalysis, which allowed realization of the cross-coupling of aryl bromides and carboxylic acids through efficient energy transfer from HiBRCP to nickel complexes. Thus, the study on the relationship between structural manipulation and their photophys. properties provided guidance for further modification of Cercosporin, which could be applied to more meaningful and challenging energy-transfer reactions.

Zhang, Yan;Li, Yuhao;Su, Chengyong;Barboiu, Mihail research published 《 Dynameric Frameworks with Aggregation-Induced Emission for Selective Detection of Adenosine Triphosphate》, the research content is summarized as follows. Luminogenic materials with aggregation-induced emission (AIE) have attracted considerable interest for applications. If these systems aggregate, the free rotation of their scaffold is restricted, and as a consequence the photoluminescence increases. Herein, the first exptl. observation of a “dynameric effect” on AIE is described. A comparison is made of the AIE of mol. and dynameric sensors that exhibit non-linear turn-on switching of fluorescence upon their interaction with ATP (ATP). Confirmation was obtained from the enhanced ATP detection with multivalent dynameric networks compared with a mol. sensor. The dynamic, reversible behavior of the imine linkages is critical to produce this enhancement, as a static, imine-reduced, polymeric sensor showed decreased AIE activity. The dynameric frameworks showed selectivity for ATP over ADP, and adenosine monophosphate over guanosine triphosphate or cytidine triphosphate. Together, these results will accelerate the systematic discovery of efficient adaptive biomimetic sensors.

Zhang, Xuan;Nottingham, Kyle G.;Patel, Chirag;Alegre-Requena, Juan V.;Levy, Jeffrey N.;Paton, Robert S.;McNally, Andrew research published 《 Phosphorus-mediated sp2-sp3 couplings for C-H fluoroalkylation of azines》, the research content is summarized as follows. Fluoroalkyl groups profoundly affect the phys. properties of pharmaceuticals and influence almost all metrics associated with their pharmacokinetic and pharmacodynamic profile. Drug candidates increasingly contain trifluoromethyl (CF3) and difluoromethyl (CF2H) groups, and the same trend in agrochem. development shows that the effect of fluoroalkylation translates across human, insect and plant life. New fluoroalkylation reactions have undoubtedly stimulated this shift; however, methods that directly convert C-H bonds into C-CF2X groups (where X is F or H) in complex drug-like mols. are rare. Pyridines are the most common aromatic heterocycles in pharmaceuticals, but only one approach – via fluoroalkyl radicals – is viable for achieving pyridyl C-H fluoroalkylation in the elaborate structures encountered during drug development. Here we develop a set of bench-stable fluoroalkylphosphines that directly convert the C-H bonds in pyridine building blocks, drug-like fragments and pharmaceuticals into fluoroalkyl derivatives No preinstalled functional groups or directing groups are required. The reaction tolerates a variety of sterically and electronically distinct pyridines, and is exclusively selective for the 4-position in most cases. The reaction proceeds through initial formation of phosphonium salts followed by sp2-sp3 coupling of phosphorus ligands – an underdeveloped manifold for forming C-C bonds. Thus, e.g., treatment of 2-phenylpyridine with (fluoroalkyl)phosphine I, Tf2O and DBU afforded intermediate phosphonium salt (not isolated) which, upon treatment with TfOH, MeOH and water afforded II (89%).

A series of thiosemicarbazone derivatives I [R1 = H, 4-MeO, 2-Br, 3-Br, 4-Br; R2 = H, Me, 2-pyridyl, etc.; R3 = 2-furyl, 3-indolyl, 2-pyridyl, etc.; n = 0, 1, 2] containing different aromatic heterocyclic groups was synthesized and the tridentate donor system of the lead compound was optimized. Most of the target compounds I showed improved antiproliferative activity against MGC803 cells. SAR studies revealed that compound I [R1 = 4-MeO, R2 = Me, R3 = 2-pyridyl, n = 0] displayed significant advantages in inhibition effect with an IC50 value of 0.031μM, and better selectivity between cancer and normal cells than 3-AP and DpC (about 15- and 5-fold improved resp.). Besides, compound I [R1 = 4-MeO, R2 = Me, R3 = 2-pyridyl, n = 0] showed selective antiproliferative activity in not only other cancer cells but also different gastric cancer cell lines. In-depth mechanism studies showed that compound I [R1 = 4-MeO, R2 = Me, R3 = 2-pyridyl, n = 0] could induce mitochondria-related apoptosis which might be related to the elevation of intracellular ROS level, and cause cell cycle arrest at S phase. Moreover, compound I [R1 = 4-MeO, R2 = Me, R3 = 2-pyridyl, n = 0] could evidently suppressed the cell migration and invasion by blocking the EMT (epithelial-mesenchymal transition) process. Consequently, our studies provided a lead optimization strategy of thiosemicarbazone derivatives I which would contribute to discover high-efficiency and low-toxicity agents for the treatment of gastric cancer.

Zhang, Xiaomeng;Wang, Yazhou;Li, Xue;Wu, Jie;Zhao, Liwen;Li, Wei;Liu, Jian research published 《 Dynamics-Based Discovery of Novel, Potent Benzoic Acid Derivatives as Orally Bioavailable Selective Estrogen Receptor Degraders for ERα+ Breast Cancer》, the research content is summarized as follows. The estrogen receptor α (ERα) is identified as an effective target for the treatment of ERα+ breast cancer; thus, discovery of novel selective estrogen receptor degraders (SERDs) are developed as an effective method to overcome the resistance of breast cancer. Herein, the hot-spot residues for protein-ligand interaction between SERDs and ERα are analyzed by mol. dynamic simulation technol., focusing on the hot-spot residues for four series of designed and synthesized SERDs. SAR studies revealed that while the acrylic acid moiety of AZD9496 is scaffold hopping into benzoic acid, compound D24 exhibits potent binding affinity with ERα, good degradation efficacy of ERα, and inhibitory effect against the MCF-7 breast cancer cell line. Besides, D24 also displays good antitumor efficacy in the MCF-7 human breast cancer xenograft model in vivo, favorable pharmacokinetic properties, excellent druggability, and good safety property, making D24 as a promising drug candidate of SERD for further evaluation.
