Zhang, Xiao published the artcileDesign, Synthesis, and Synergistic Activity of Eight-Membered Oxabridge Neonicotinoid Analogues, Safety of 1-(Chloromethyl)-4-(trifluoromethyl)benzene, the publication is Journal of Agricultural and Food Chemistry (2021), 69(10), 3005-3014, database is CAplus and MEDLINE.

Insecticide synergists are sought-after due to their potential in improving the pesticide control efficacy with a reduced dose of an active ingredient. We previously reported that a cis-configuration neonicotinoid (IPPA08) exhibited specific synergistic activity toward neonicotinoid insecticides. In this study, we synthesized a series of structural analogs of IPPA08 by converting the pyridyl moiety of IPPA08 into Ph groups, via facile double-Mannich condensation reactions between nitromethylene compounds and glutaraldehyde. All of the oxabridged neonicotinoid compounds were found to increase the toxicity of imidacloprid against Aphis craccivora. Notably, compound (I) at 0.75 mg/L lowered the LC₅₀ value of imidacloprid against A. craccivora by 6.54-fold, while a 3.50-fold reduction of the LC₅₀ value was observed for IPPA08. The results of bee toxicity test showed that compound I display selectivity in its effects on imidacloprid toxicity against the honey bee (Apis mellifera L.). In summary, replacing the pyridyl ring with a Ph ring was a viable approach to obtain a novel synergist with oxabridged moiety for neonicotinoid insecticides.

Hu, Yuhan published the artcileEnzyme-instructed self-assembly of peptide-drug conjugates in tear fluids for ocular drug delivery, Recommanded Product: 2-Chlorotrityl chloride, the publication is Journal of Controlled Release (2022), 261-271, database is CAplus and MEDLINE.

In vivo self-assembly of small mols. offers an excellent opportunity for targeted and long-term accumulation of a therapeutic agent at the lesion site. Here we demonstrate the strategy of enzyme-instructed self-assembly (EISA) by designing a phosphorylated peptide-drug (IBF-HYD-GFFpY) precursor through the ester bond to release active drugs at the target site. Meanwhile, the in vivo assembly can be achieved by the catalysis of alk. phosphatase (ALP) in the tear fluid for ocular drug delivery efficiently. The in vitro enzymic experiments indicate that the dephosphorylation of IBF-HYD-GFFpY occurs firstly with the yield of IBF-HYD-GFFY which subsequently self-assembles into the supramol. hydrogel to afford sustained drug release over 96 h. In the treatment of lipopolysaccharide (LPS)-activated Raw 264.7 macrophages, IBF-HYD-GFFpY exerts the more potent anti-inflammatory efficacy than that of free ibuprofen (IBF) at the concentration of 200 μM. Moreover, the aqueous solution of IBF-HYD-GFFpY via topical instillation hardly causes ocular irritation, and displays longer precorneal retention compared to the conventional eye drop formulation. In addition, in the in vivo study, a rabbit model of endotoxin-induced uveitis (EIU) evidences the comparable therapeutic efficacy of IBF-HYD-GFFpY eye drops with that of clin. used 0.1 wt% diclofenac (DIC) sodium eye drops by the reduction of macrophage and leukocyte influx. This work, in situ EISA in the tear microenvironment directing in vivo self-assembly of small mols., may guide a powerful approach for developing enzymic self-assembled mols. as an efficient delivery system of ocular drugs.

Chen, Jing published the artcileA novel”turn-off”fluorescence assay based on acid-copper nanoclusters in deep eutectic solvent micelles for co-aggregation inducing fluorescence enhancement and its application, Safety of N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Talanta (2021), 223(Part_1), 121731, database is CAplus and MEDLINE.

As mixtures, deep eutectic solvent (DES) is designability. By adjusting the long alkyl chain hydrogen bond acceptors (HBAs) or hydrogen bond donors (HBDs), the DES displays surfactant characteristics and can form micelles. Hence, a novel, simple, facile and green natural organic acids capped copper nanoclusters (Aci-CuNCs) was synthesized and the spectrum behavior of Aci-CuNCs in DES micelles was researched. It was found that the surfactant-like DES can form micellar co-aggregation with Aci-CuNCs, resulting in the fluorescence (FL) intensive of Aci-CuNCs increase. Corresponding performance of spectral properties of Aci-CuNCs in DES medium were systematically studied by fourier transform IR spectrometer, 3D FL spectroscopy, FL emission/excitation spectra, UV absorption spectroscopy. In the mechanism exploration part, on the one hand, the existence of micellar co-aggregation was confirmed by the conductivity, the mass effect of DES, dynamic light scattering and transmission electron microscopy. On the other hand, the influence of different kinds of DESs (types of HBAs/HBDs, molar ratio) and some possible factors (ionic strength and temperature) were discussed in detail to investigate the main driving forces for the formation of micellar co-aggregates. The results of mechanism exploration prove that the long alkyl chain of DES is amphiphilic which can form micellar co-aggregation with Aci-CuNCs through hydrogen bonding. The DES micelle provides Aci-CuNCs with a relatively stable and closed micro-environment which can effectively prevent collisions with water mols. and weakening of fluorescence intensity. On the basic of the above research, a “turn-off” fluorimetric method based on Aci-CuNCs in DES medium was applied for the determination of Fe³⁺. Under the optimum conditions, the assay worked in the Fe³⁺ concentration ranges from 1 to -20μM and had a detection limit of 0.0374μM. Method validation study illustrates the proposed system can provide a good accuracy, repeatability and stability conditions. Furthermore, the real sample anal. result demonstrates that no obvious matrix effect is found. As a consequence, the FL assays (Aci-CuNCs-based DES) composed of natural organic acid capped CuNCs and green solvent DES provides a simple, gentle and environmentally friendly method for the detection of iron ions.

EtCOCPh₂CH₂CHMeNMe₂ (I), was prepared from ClCH₂CHMeOH (II) in 4 steps. Thus, amination of II with Me₂NH and subsequent SOCl₂ chlorination gave Me₂NCH₂CHClMe, which condensed with Ph₂CHCN in aqueous NaOH to give Ph₂C(CN)CH₂CHMeNMe₂. Reaction of the latter with EtMgBr and subsequent hydrolysis gave I. Nitration of furfural by HNO₃-H₂SO₄ in Ac₂O gave 2-(diacetoxymethyl)-5-nitrofuran, which was treated with 73% H₂SO₄ to give 5-nitrofurfural, an intermediate in the preparation of furazolidone.

Bao, Ting published the artcileSynthesis and structure of lateral halogenated V-shaped liquid crystal molecules based on a 1,7-naphthalene central core and alkylthio tails, Synthetic Route of 350-30-1, the publication is Liquid Crystals (2014), 41(12), 1687-1695, database is CAplus.

A series of small angle bent-core (V-shaped) mesogens carrying 1,7-naphthalene as a central core linked with lateral halogenated (chlorinated or fluorinated) Schiff-base side wings and alkylthio terminal tails of variable carbon number (n = 12, 16) was synthesized in order to reduce the transition temperature and improve the phase stability of bent-core liquid crystal mols. Differential scanning calorimetry (DSC), polarising optical microscopy (POM), small-angle X-ray scattering system (SAXS) and two-dimensional X-ray diffractometer were applied to ascertain the mesomorphic structure and phase transition temperatures of the compounds The results confirm that all the mols. show thermotropic liquid crystalline behavior and exhibit hexagonal columnar phase (Colh) in a certain temperature range. Compared with the homologous compounds without lateral halogen, the cleaning point temperature of lateral halogenated V-shaped compounds generally decrease and the Colh phase ranges are more extensive. The influence of lateral chlorine on the cleaning point temperature is more obvious, as well as the effect of lateral fluorine on the range of Colh phase.

Using iso-Bu chloroformate as a carbon monoxide equivalent, N-(bromoaryl) α-substituted acrylamides such as I underwent reductive arylacylation reactions with alkyl iodides such as iodocyclohexane or benzylic chlorides in the presence of NiBr₂(DME), and 4,4′-dimethyl-2,2′-bipyridine using manganese or zinc as reductant in 1:1 DMA:THF to yield oxoalkyl oxindoles such as II. The mechanism was studied using an alkyl iodide susceptible to radical cyclization and stoichiometric reaction of a oxindolylmethyl nickel complex; a mechanism involving reaction of alkyl radicals with nickel complexes is proposed. Reaction using a nonracemic octahydrobinaphthyl phosphoramidate ligand yielded product in 8% yield and 50% ee.
