Guerra Faura, Gabriel;Nguyen, Tena;France, Stefan research published 《 Catalyst-Controlled Chemodivergent Reactions of 2-Pyrrolyl-α-diazo-α-ketoesters and Enol Ethers: Synthesis of 1,2-Dihydrofuran Acetals and Highly Substituted Indoles》, the research content is summarized as follows. A catalyst-controlled, chemodivergent reaction of pyrrolyl-α-diazo-α-ketoesters, e.g., I (R = H, Et, Ph, R¹ = Me, Bn, Ts), with enol ethers, e.g., 2-methoxypropene, dihydropyran, and (1-ethoxyvinyl)benzene, is reported. While Cu(II) catalysts selectively promoted a [3+2]-cycloaddition to provide pyrrolyl-substituted 2,3-dihydrofuran (DHF) acetals, e.g., II, dimeric Rh(II) catalysts afforded 6-hydroxyindole-7-carboxylates, e.g., III, via an unreported [4+2]-benzannulation. The choice of enol ether proved to be crucial in determining both regioselectivity and yield of the resp. products (up to 91% yield for Cu(II) and 82% for Rh(II) catalysis). Furthermore, the DHF acetals were shown to serve as precursors to 7-hydroxyindole-6-carboxylates (isomeric to the indoles formed from Rh) and highly substituted furans in the presence of Lewis acids. Thus, from a common pyrrolyl-α-diazo-α-ketoester, up to three unique heterocyclic scaffolds can be achieved based on catalyst selection.

Plant pathogenic fungi decrease the quality and productivity of plant production The botanical fungicides have better biocompatibility and rapid biodegradation, little or no cross resistance, and the structural diversity, and thus are beneficial to deal with plant fungal diseases. Osthole has been widely used as the com. botanical fungicide against powdery mildew in China. In this article, a series of osthole derivatives were synthesized, which resp. contain different substituents on the benzene ring, at the C8-position and pyrone ring. All the target compounds were evaluated in vitro for their antifungal activity against resistant phytopathogenic fungi. Colletotrichum fragariae, Strawberry Botrytis cinerea, Kiwifruit Botrytis cinerea, Kiwifruit brown Rots, which are common in fruit fungal diseases. The compound 7-hydroxy-8-methyl-4-(trifuoromethyl)-2H-chromen-2-one (I) was identified as the most promising candidate with the EC₅₀ values at 38.7μg/mL against Colletotrichum Fragariae, 14.5μg/mL against Strawberry Botrytis Cinerea and 24.3μg/mL against Kiwifruit Botrytis Cinerea, resp., whereas the antifungal activity against resistant phytopathogenic fungi. of osthole is too low to be used (EC₅₀ > 400 ppm). The results of mycelial relative conductivity determination, PI uptake and fluorescence spectroscopy indicated that the cell membrane of fungi is the key action site of I. Besides, I has the potent inhibitory activity against both of plant and human pathogenic bacteria. Our studies showed that C₄ was worthy for further attention as a promising botanical fungicide candidate in crop protection.

Two different synthetic strategies were employed: route A, based on Pd-catalyzed cyclodehydrohalogenation of α,α-disubstituted N-arylpyrroles, and route B, using a dipolar 1,3-cycloaddition reaction of azomethine ylides (PAMYs) to functionalized acenaphthylenes. Mols. of the resulting ullazines were almost flat, leading to strong π-π interactions in the solid state. The new ullazines were highly fluorescent (with a quantum yield of up to 0.89 for the naphthalimide-fused system), and showed moderate solvatochromism with no fluorescence quenching in polar solvents. Stepwise two-electron oxidation of the ullazines was possible, yielding reversibly the corresponding ullazine radical cations and dications. Edge expansion of the ullazine core with methylene bridges was addnl. shown to produce an ullazine analog containing two seven-membered rings in its structure, which was characterized by axial chirality and could be resolved into enantiomers.

Two-dimensional (2D) organic-inorganic hybrid copper perovskites have drawn tremendous attention as promising multifunctional materials. Herein, by incorporating ortho-, meta-, and para-chlorine substitutions in the benzylamine structure, we first report the influence of positional isomerism on the crystal structures of chlorobenzylammonium copper(II) chloride perovskites A₂CuCl₄. 2D polar ferromagnets (3-ClbaH)₂CuCl₄ and (4-ClbaH)₂CuCl₄ (ClbaH⁺ = chlorobenzylammonium) are successfully obtained. They both adopt a polar monoclinic space group Cc at room temperature, displaying significant differences in crystal structures. In contrast, (2-ClbaH)₂CuCl₄ adopts a centrosym. space group P2₁/c at room temperature This associated structural evolution successfully enhances the phys. properties of the two polar compounds with high thermal stability, discernible second harmonic generation (SHG) signals, ferromagnetism, and narrow optical band gaps. These findings demonstrate that the introduction of chlorine atoms into the interlayer organic species is a powerful tool to tune crystal symmetries and phys. properties, and this inspires further exploration of designing high-performance multifunctional copper-based materials.

Han, Shuwen;Zhou, Wei;Zhuang, Chunlin;Chen, Fener research published 《 Structure-Based design of Marine-derived Meridianin C derivatives as glycogen synthase kinase 3β inhibitors with improved oral bioavailability: From aminopyrimidyl-indoles to the sulfonyl analogues》, the research content is summarized as follows. Glycogen synthase kinase 3β (GSK-3β) has become an attractive target for the treatment of diabetes. Compound I is an indole-based GSK-3β inhibitor designed from the Meridianin C, a marine natural product (MNP) isolated from Aplidium meridianum. However, this compound has a moderate inhibitory activity toward GSK-3β (IC₅₀ = 24.4 μM), moderate glucose uptake (38%), and especially, a low oral bioavailability (F = 11.4%). In the present study, applying the structure-based design strategy, a series of derivatives modified on the indole moiety were synthesized based on the lead compound I, followed by evaluating their cytotoxic activity, antihyperglycemic activity, and kinase inhibitory activity. Among this series, compound 6x with a sulfonyl group displayed the highest glucose uptake (83.5%) in muscle L6 cells, showing much higher inhibitory activity against GSK-3β (IC₅₀ = 5.25 μM). Mol. docking indicated that compound 6x was properly inserted into the ATP-binding binding pocket of GSK-3β with a higher docking score (-8.145 kcal/mol) compared with that of compound I (-6.950 kcal/mol), interpreting the higher kinase inhibitory activity toward GSK-3β. Remarkably, compound 6x showed favorable drug-like properties, including significantly better oral bioavailability (F = 47.4%) and no two-week acute toxicity at a dose of 1g/kg. Our findings suggest that these MNP-derived sulfonyl indole derivatives could be used as lead compounds for the development of anti-hyperglycemic drugs.
