A promising method for preparation of the superparamagnetic and strongly magnetic Fe₃O₄@PDA core-shell sub-microsphere-supported nano-palladium catalyst for catalyzing the hydrogenation reduction of halogenated aromatic nitro compds was reported. The catalyst showed a high selectivity of greater than 96% and effectively inhibited the occurrence of the side reactions of dehalogenation and C-N coupling. The optimum condition of the hydroredn. reaction was when THF is used as solvent and the reaction occurred at 50° for 5 h. The selectivity of the chlorinated aromatic amine and the fluorinated aromatic amine products exceeded 99% and the yield exceeds 90%. Only a small amount of dehalogenated products and C-N coupling byproducts were produced in the brominated aromatic compound and the iodinated aromatic compound

Chen, Jianping published the artcileIridium-Catalyzed Synthesis of Diaryl Ethers by Means of Chemoselective C-F Bond Activation and the Formation of B-F Bonds, Category: chlorides-buliding-blocks, the publication is Chemistry – An Asian Journal (2015), 10(2), 468-473, database is CAplus and MEDLINE.

Transition-metal-catalyzed C-F activation, in comparison with C-H activation, is more difficult to achieve and therefore less fully understood, mainly because carbon-fluorine bonds are the strongest known single bonds to carbon and have been very difficult to cleave. Transition-metal complexes are often more effective at cleaving stronger bonds, such as C(sp²)-X vs. C(sp³)-X. Here, the iridium-catalyzed C-F activation of fluorarenes was achieved through the use of bis(pinacolato)diboron with the formation of the B-F bond and self-coupling. This strategy provides a convenient method with which to convert fluoride aromatic compounds into sym. diaryl ether compounds Moreover, the chemoselective products of the C-F bond cleavage were obtained at high yields with the C-Br and C-Cl bonds remaining.

Lin, Runfeng published the artcileThe development of HEC-866 and its analogues for the treatment of idiopathic pulmonary fibrosis, Name: 3-Chloro-4-fluoronitrobenzene, the publication is RSC Medicinal Chemistry (2021), 12(7), 1222-1231, database is CAplus and MEDLINE.

Idiopathic pulmonary fibrosis (IPF) is a chronic progressive lung disease with a typical survival time between three to five years. Two drugs, pirfenidone and nintedanib have been approved for the treatment of IPF, but they have limited efficacy. Thus, the development of new drugs to treat IPF is an urgent medical need. In this paper we report the discovery of a series of orally active pyrimidin-4(3H)-one analogs which exhibit potent activity in in vitro assays. Among them, HEC-866 showed promising efficacy in rat IPF models. Since HEC-866 also had good oral bioavailability, a long half-life and favorable long-term safety profiles, it was selected for further clin. evaluation.

Zhu, Xiao-Lei published the artcileNatural product neopeltolide as a cytochrome bc₁ complex inhibitor: Mechanism of action and structural modification, Formula: C6H3ClFNO2, the publication is Journal of Agricultural and Food Chemistry (2019), 67(10), 2774-2781, database is CAplus and MEDLINE.

The marine natural product neopeltolide was isolated from a deep-water sponge specimen of the family Neopeltidae. Neopeltolide has been proven to be a new type of inhibitor of the cytochrome bc₁ complex in the mitochondrial respiration chain. However, its detailed inhibition mechanism has remained unknown. In addition, neopeltolide is difficult to synthesize because of its very complex chem. structure. In the present work, the binding mode of neopeltolide was determined for the first time by integrating mol. docking, mol. dynamics simulations, and mol. mechanics Poisson-Boltzmann surface area calculations, which showed that neopeltolide is a Q_o site inhibitor of the bc₁ complex. Then, according to guidance via inhibitor-protein interaction anal., structural modification was carried out with the aim to simplify the chem. structure of neopeltolide, leading to the synthesis of a series of new neopeltolide derivatives with much simpler chem. structures. The calculated binding energies (ΔG_cal) of the newly synthesized analogs correlated very well (R² = 0.90) with their exptl. binding free energies (ΔG_exp), which confirmed that the computational protocol was reliable. Compound 45, bearing a di-Ph ether fragment, was successfully designed and synthesized as the most potent candidate (IC₅₀ = 12 nM) against porcine succinate cytochrome c reductase. The mol. modeling results indicate that compound 45 formed a π-π interaction with Phe274 and two hydrogen bonds with Glu271 and His161. The present work provides a new starting point for future fungicide discovery to overcome the resistance that the existing bc₁ complex inhibitors are facing.

The synthesis of novel anthranilic diamides derivatives I [R = HC, N, Cl-C; R⁴ = O₂N, F₃C, i-Pr, etc; R⁵ = Me, i-Pr] incorporating pyrrole moiety targeting at insect RyRs. The structures I were confirmed by ¹H NMR, ¹³C NMR, ¹⁹F NMR and HRMS. The preliminary bioassay results indicated that most of the title compounds I showed good to excellent insecticidal activities against oriental armyworm (Mythimna separata) and diamondback moth (Plutella xylostella). For oriental armyworm, I [R = N; R⁴ = H; R⁵ = Me] displayed the same level of larvicidal activity as the pos. control chlorantraniliprole, with the LC₅₀ value of 0.21 mg/L. For diamondback moth II [R⁵ = Me; X = Br], [R⁵ = i-Pr; X = Br], [R⁵ = Me; X = Cl] and [R⁵ = i-Pr; X = Cl] exhibited higher insecticidal activities than chlorantraniliprole. In particular, In had 50% larvicidal activity at 0.00001 mg/L. Calcium imaging technique was applied to study the effect of I [R = N; R⁴ = H; R⁵ = Me] and II [R⁵ = Me; X = Br, Cl] on the intracellular calcium ion concentration ([Ca²⁺]i) in central neurons isolated from oriental armyworm. The results indicated that the tested compoundsI and II, like chlorantraniliprole was activate the insect ryanodine receptors. Furthermore, comparative mol. field (CoMFA) anal. and d. functional theory (DFT) calculations were carried out to study the structure-activity relationship (SAR).

Sameshima, Tomoya published the artcileDiscovery of an Irreversible and Cell-Active BCL6 Inhibitor Selectively Targeting Cys53 Located at the Protein-Protein Interaction Interface, Recommanded Product: 3-Chloro-4-fluoronitrobenzene, the publication is Biochemistry (2018), 57(8), 1369-1379, database is CAplus and MEDLINE.

B-cell lymphoma 6 (BCL6) is the most frequently involved oncogene in diffuse large B-cell lymphomas (DLBCLs). BCL6 shows potent transcriptional repressor activity through interactions with its corepressors, such as BCL6 corepressor (BCOR). The inhibition of the protein-protein interaction (PPI) between BCL6 and its corepressors suppresses the growth of BCL6-dependent DLBCLs, thus making BCL6 an attractive drug target for lymphoma treatments. However, potent small-mol. PPI inhibitor identification remains challenging because of the lack of deep cavities at PPI interfaces. This paper reports the discovery of a potent, cell-active, small-mol. BCL6 inhibitor, BCL6-i (8), that operates through irreversible inhibition. First, we synthesized an irreversible lead compound 4, which targets Cys53 in a cavity on the BCL6 BTB domain dimer by introducing an irreversible warhead to a high-throughput screening hit compound 1. Further chem. optimization of 4 based on kinact/KI evaluation produced BCL6-i with a kinact/KI value of 1.9 × 104 M-1s-1, corresponding to a 670-fold improvement in potency compared to 4. By exploiting the property of irreversible inhibition, engagement of BCL6-i to intracellular BCL6 was confirmed. BCL6-i showed intracellular PPI inhibitory activity between BCL6 and its corepressors, thus resulting in BCL6-dependent DLBCL cell-growth inhibition. BCL6-i is a cell-active chem. probe with the most potent BCL6 inhibitory activity reported to date. The discovery process of BCL6-i illustrates the utility of irreversible inhibition for identifying potent chem. probes for intractable target proteins.

Qu, Renyu published the artcileDesign, synthesis and bioactivity of new pyrimidyl-salicylate inhibitors, Recommanded Product: 3-Chloro-4-fluoronitrobenzene, the publication is Youji Huaxue (2019), 39(8), 2303-2310, database is CAplus.

Acetohydroxyacid synthase (AHAS) was one of important herbicidal targets. However, the issue of weed resistance to com. AHAS inhibitors has become one of the largest obstacles for their application. Therefore, there is a high demand to design new anti-resistance AHAS inhibitors. Herein, based on the reported low resistance AHAS inhibitors, a series of pyrimidyl-salicylates with “double oxygen bridge” utilized the “conformation flexibility anal.” strategy were designed. All the synthesized compounds were characterized by ¹H NMR, ¹³C NMR and HRMS. The bioactivity results showed that most of the derivatives displayed good inhibitory activities against P197L mutant. Especially, 2-((4,6-dimethoxypyrimidin-2-yl)oxy)-6-(2-fluoro-4-nitrophenoxy)-4-methylbenzoic acid (6l) was identified as the most potent anti-resistance AHAS inhibitor. In addition, some compounds showed good weed control for resistant Descurainia sophia (P197L AHAS). Most importantly, 2-((4,6-dimethoxypyrimidin-2-yl)oxy)-6-(2-fluorophenoxy)-4-methylbenzoic acid (6b) showed 80% herbicidal activities against sensitive and resistant Descurainia sophia at the dosage of 150 g ai/ha. These results indicated that this type of compounds worth of the further investigation.
