Grenz, David C.;Rose, Daniel;Wossner, Jan S.;Wilbuer, Jennifer;Adler, Florin;Hermann, Mathias;Chan, Chin-Yiu;Adachi, Chihaya;Esser, Birgit research published 《 Spiroconjugated Tetraaminospirenes as Donors in Color-Tunable Charge-Transfer Emitters with Donor-Acceptor Structure》, the research content is summarized as follows. Charge-transfer emitters are attractive due to their color tunability and potentially high photoluminescence quantum yields (PLQYs). Herein, the authors present tetraaminospirenes as donor moieties, which, in combination with a variety of acceptors, furnished 12 charge-transfer emitters with a range of emission colors and PLQYs of up to 99%. The spatial separation of their frontier MOs was obtained through careful structural design, and two donor-acceptor structures were confirmed by X-ray crystallog. A range of photophys. measurements supported by DFT calculations shed light on the optoelectronic properties of this new family of spiro-NN-donor-acceptor dyes.

Guo, Yuying;Chen, Jiabao;Ren, Dan;Du, Bo;Wu, Lei;Zhang, Yuanyuan;Wang, Zhouyu;Qian, Shan research published 《 Synthesis of osthol-based botanical fungicides and their antifungal application in crop protection》, the research content is summarized as follows. 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.

Hager, Joanna;Kang, Seongsoo;Chmielewski, Piotr J.;Lis, Tadeusz;Kim, Dongho;Stepien, Marcin research published 《 Acenaphthylene-fused ullazines: fluorescent π-extended monopyrroles with tunable electronic gaps》, the research content is summarized as follows. π-Extended dibenzoullazines, e.g., I (R = 2,6-idisopropylphenyl, 2,9-di-tert-Bu, etc.) containing an acenaphthylene subunit were designed and synthesized. 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.

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.

Hasannezhad, Najme;Shadjou, Nasrin research published 《 KCC-1-nPr-NH-Arg as an efficient organo-nanocatalyst for the green synthesis of 1,8-dioxo decahydroacridine derivatives》, the research content is summarized as follows. In the present work, an innovative biocompatible heterogeneous organo-nanocatalyst is prepared based on the grafting of arginine amino acid on the channels and pores of dendritic fibrous nanosilica. The designed organo-nanocatalyst (KCC-1-nPr-NH-Arg) was characterized by using field emission SEM, Fourier transform IR spectroscopy, energy dispersive X-ray spectroscopy, map anal., and adsorption/desorption instruments. The results of anal. show that the engineered catalyst has uniform fibrous spheres and dendritic structure with high surface area (104.9 m²/g) and great pore volume (0.83 cm³ g^-1). Because of exceptional dendritic structure of the prepared organo-nanocatalyst, the active sites are available and the difusion and adsorption capacity of the reagents and products increase in the pores and channels of the catalyst. Hence, KCC-1-nPr-NH-Arg was used as an capable heterogeneous basic nanocatalyst in the synthesis of 1,8-dioxo decahydroacridine derivatives from the one-pot four component reactions of aromatic aldehydes, dimedone, and ammonium acetate in solvent free conditions with shorter reaction times (13-35 min) and higher yields (94%-98%) in evaluation with other reported works.

Authors present a modular, synthetic entry to polysubstituted pyrroles employing readily available 2,5-dihydrothiophenes. Ring-opening of the heterocycle provides access to a panel of 1,3-dienes which underwent pyrrole formation in the presence of inexpensive chloramine-T trihydrate. The transformation is conducted in an open flask and proceeds at ambient temperatures (23°) in nondry solvents. A careful adjustment of the electronics and sterics of the 1,3-diene precursor allows for the isolation of key intermediates. DFT studies identified a reaction mechanism that features a 6π-electrocyclization of a sulfilimine intermediate followed by spontaneous ring-contraction to reveal the pyrrole skeleton.
