Zhang, Feng; Ma, Jun; Tan, Ya; Yu, Gang; Qin, Hongxin; Zheng, Lirong; Liu, Hongbo; Li, Run published the artcile< Construction of Porphyrin Porous Organic Cage as a Support for Single Cobalt Atoms for Photocatalytic Oxidation in Visible Light>, Synthetic Route of 3959-07-7, the main research area is construction porphyrin porous organic cage support single cobalt atom; oxidative coupling reaction catalyst benzylamine.

The construction of an appropriate support for a single atom catalyst plays an important role in delivering a high catalytic performance. However, most reported host materials suffer the drawbacks of low photostability and limited visible light absorption. Herein, we report a porous organic cage as a high-quality support for single metal atoms by a facile stepwise nucleophilic substitution approach. Thanks to its intrinsic advantages of extended visible light absorption, suppressed charge recombination, and improved electron transfer, the obtained single Co atoms anchored organic cage (CoP@POC) demonstrates a prominent photocatalytic efficiency for oxidation of amines into imines in visible light. An excellent reaction conversion and selectivity up to 99%, associated with a turnover frequency (TOF) of 1389 h-1 and 22 989 mmol g-1 h-1 are achieved based on organic cage and single Co atoms, resp., which outperforms most reported photocatalysts. Moreover, a negligible conversion decrease in 5 repeating cycles and no photobleaching after the reaction was detected, implying a remarkable photostability of CoP@POC.

Tumor necrosis factor α (TNFα) is a soluble cytokine that is directly involved in systemic inflammation through the regulation of the intracellular NF-κB and MAPK signaling pathways. The development of biol. drugs that inhibit TNFα has led to improved clin. outcomes for patients with rheumatoid arthritis and other chronic autoimmune diseases; however, TNFα has proven to be difficult to drug with small mols. Herein, we present a two-phase, fragment-based drug discovery (FBDD) effort in which we first identified isoquinoline fragments that disrupt TNFα ligand-receptor binding through an allosteric desymmetrization mechanism as observed in high-resolution crystal structures. The second phase of discovery focused on the de novo design and optimization of fragments with improved binding efficiency and drug-like properties. The 3-indolinone-based lead compound 12 (I) presented here displays oral, in vivo efficacy in a mouse glucose-6-phosphate isomerase (GPI)-induced paw swelling model comparable to that seen with a TNFα antibody.

Developing well-defined iron-based catalysts for olefin metathesis would be a breakthrough achievement in the field not only to replace existing catalysts by inexpensive metals but also to attain a new reactivity taking advantage of the unique electronic structure of the base metals. Here, we present a two-coordinate homoleptic iron complex, Fe(HMTO)2 [HMTO=O-2,6-(2,4,6-Me3C6H2)2C6H3], that is capable of performing ring-opening metathesis polymerization of norbornene to produce highly stereoregular polynorbornene (99% cis, syndiotactic). The use of heteroleptic Fe(HMTO)(RO) [RO=(CH3)2CF3CO, CH3(CF3)2CO, or Ph(CF3)2CO] prepared in situ significantly increases the polymerization rate while preserving selectivity. The resulting polymers were characterized by 1H and 13C NMR spectroscopy and gel-permeation chromatog.

Penicillium digitatum (green mold) is pathogenic fungi and causes citrus fruit postharvest rotting that leads to huge economic losses across the world. The current study was aimed to develop a new derivative of cinnamaldehyde (4-methoxycinnamaldehyde) through the cross-hydroxyaldehyde condensation method with benzaldehyde substituted by a benzene ring under the catalysis of alk. reagent and, moreover, to test their antifungal potential against P. digitatum, the major citrus fruit rotting fungi. Multiple derivatives of cinnamaldehyde viz. 4-nitro CA, 4-chloro CA, 4-bromo CA, 4-Me CA, 4-methoxy CA, and 2,4-dimethoxy CA were synthesized in the current study whereas the 4-methoxy CA showed highest antifungal actions for citrus fruit postharvest rotting fungi P. digitatum. Moreover, 4-methoxy CA was found to reduce the spore germination and growth by damaging the fungal cell membrane, as well as declined the levels of reducing sugars.

A powerful, broadly applicable cross-coupling protocol that enabled carbon-carbon bond formation at highly sterically hindered carbon centers (both sp2 and sp3) by employing organocopper reagents under palladium catalysis was described. Exptl. studies and theor. calculations indicated that the key to the unique reactivity of copper was the relatively low activation energy of the compact transmetalation transition state, due to Cu(I)-Pd(II) interaction, which was associated with small values of deformation energy of the reactants. This reaction was applicable to a variety of bulky substrates, including compounds inert to previous cross-coupling chem. and has high functional group tolerance.

Yan, Nicholas L.; Santos-Martins, Diogo; Nair, Reji; Chu, Alan; Wilson, Ian A.; Johnson, Kristen A.; Forli, Stefano; Morgan, Gareth J.; Petrassi, H. Michael; Kelly, Jeffery W. published the artcile< Discovery of Potent Coumarin-Based Kinetic Stabilizers of Amyloidogenic Immunoglobulin Light Chains Using Structure-Based Design>, Quality Control of 405931-46-6, the main research area is coumarin stabilizer amyloidogenic Ig light chain amyloidosis inhibitor.

In Ig light-chain (LC) amyloidosis, transient unfolding or unfolding and proteolysis enable aggregation of LC proteins, causing potentially fatal organ damage. A drug that kinetically stabilizes LCs could suppress aggregation; however, LC sequences are variable and have no natural ligands, hindering drug development efforts. We previously identified high-throughput screening hits that bind to a site at the interface between the two variable domains of the LC homodimer. We hypothesized that extending the stabilizers beyond this initially characterized binding site would improve affinity. Here, using protease sensitivity assays, we identified stabilizers that can be divided into four substructures. Some stabilizers exhibit nanomolar EC50 values, a 3000-fold enhancement over the screening hits. Crystal structures reveal a key π-π stacking interaction with a conserved tyrosine residue that was not utilized by the screening hits. These data provide a foundation for developing LC stabilizers with improved binding selectivity and enhanced physicochem. properties.

To tackle the serious challenge of insect resistance and stricter environmental regulations, innovating a new eco-friendly insecticide is urgently required. A series of new phthalamides containing sulfiliminyl and sulfoximinyl moieties were designed and synthesized. In total, 30 new structures were characterized by 1H NMR spectra and HRMS. The bioassay results indicated that some title compounds exhibited excellent insecticidal activities against oriental armyworm (Pseudaletia separata Walker) and diamondback moth (Plutella xylostella (L.)). 3-Iodo-N2-[1-(N-cyano-S-methylsulfinimidoyl)-2-methylpropa-2-yl]-N1-[2-methyl-4-(perfluoropropan-2-yl)phenyl]phthalamide (I) showed the same larvicidal level as that of com. flubendiamide as a control. N2-[1-(N-Cyano-S-methylsulfonimidoyl)-2-methylpropan-2-yl]-3-iodo-N1-[2-methyl-4-(perfluoropropan-2-yl)phenyl]phthalamide (II) and 3-Iodo-N2-[2-methyl-1-[S-methyl-N-(2,2,2-trifluoroacetyl)sulfonimidoyl]propan-2-yl]-N1-[2-methyl-4-(perfluoropropan-2-yl)phenyl]phthalamide (III) exhibited outstanding activity against diamondback moth. The LC50 values of II and III were 8.33 × 10-8 and 2.34 × 10-8 mg L-1, resp., lower than that of flubendiamide (1.25 × 10-7 mg L-1). The effects of I, II and III on intracellular calcium of neurons from the beet armyworm (Spodoptera exigua) indicated that these title compounds activate the receptor-operated calcium channel. The calcium ions efflux from the calcium store on endoplasmic reticulum (ER) when treated with novel compounds The results of CoMFA calculation showed that N-cyanosulfilimines and N-trifluoroacetylsulfoximines might be of importance to the larvicidal activity. The present work demonstrated that structures containing sulfiliminyl and sulfoximinyl moieties can be considered as lead compounds for the development of new insect ryanodine receptor modulators.

Cui, Guonan; Lai, Fangfang; Wang, Xiaoyu; Chen, Xiaoguang; Xu, Bailing published the artcile< Design, synthesis and biological evaluation of indole-2-carboxylic acid derivatives as IDO1/TDO dual inhibitors>, Recommanded Product: 4-Bromo-3-formylbenzonitrile, the main research area is indole carboxylic acid preparation SAR mol docking; indoleamine tryptophan dioxygenase dual inhibitor; Dual inhibitors; Indole-2-carboxylic acid; Indoleamine 2,3-dioxygenase 1; Tryptophan 2,3-dioxygenase.

Indoleamine 2,3-dioxygenase 1 (IDO1) and tryptophan 2,3-dioxygenase (TDO) are involved in the key steps of tryptophan metabolism and are potential new targets for tumor immunotherapy. In this work, a variety of indole-2-carboxylic acid derivatives I (R1 = H, 7-F, NHAc, etc.; X = NH, NMe, S; Y = NH, S, -NHCH2-, etc.; Ar = 4-F-3-Cl-C6H3, 4-F-3-OMe-C6H3, 3-Cl-3-OMe-C6H3, etc.) were synthesized, and their inhibitory activities against both enzymes along with structure-activity relationships were investigated. As a result, a number of 6-acetamido-indole-2-carboxylic acid derivatives were found to be potent dual inhibitors with IC50 values at low micromolar levels. Among them, compound I (R1 = 6-NHAc, X = N, Y = NH, Ar = 3,4-di-F-C6H3) was the most potent inhibitor with an IC50 value of 1.17μM for IDO1, and 1.55μM for TDO, resp. In addition, a para-benzoquinone derivative II, resulted from the oxidation of compound I (R1 = 6-NHEt, X = NH, Y = NH, Ar = 4-F-3-Cl-C6H3), was also identified and it showed strong inhibition against the two enzymes with IC50 values at the double digit nanomolar level. Using mol. docking and mol. dynamic simulations, authors predicted the binding modes of this class of compounds within IDO1 and TDO binding pocket. The results provide insights for further structural optimization of this series of IDO1/TDO dual inhibitors.
