Summary: Flavone has been identified as a promising scaffold for the development of a novel drug against dengue fever. In this study, 27 flavone analogs were synthesized and evaluated for their efficacy against DENV2-infected cells. The introduction of electron-withdrawing groups on ring B significantly enhanced the activity, with two analogs showing exceptional inhibition of DENV2. Molecular docking study suggested that these potent flavone analogs target NS5 MTase and NS5 RdRp. The physicochemical properties of these analogs were within the acceptable range, and QSAR model showed a strong correlation between the anti-dengue activity and the selected molecular descriptors. This study highlights the great potential of flavone as a core structure for the development of a novel anti-dengue agent.

Summary: This study evaluates the effect of different extraction methods on the content of antioxidant compounds in different types of sugar, as well as the potential of sugar extracts in anti-diabetic activity. The results show that sugar cane extracted with acidified ethanol is the best condition to extract a high yield of phenolic acids. Less refined sugar shows the highest yield of phenolic compounds compared to brown sugar and refined sugar. Among the sugar cane derivatives, less refined sugar shows minor inhibition towards alpha-amylase and alpha-glucosidase activity compared to white sugar.

Summary: A covalent polymer of DMY-SBP was prepared for the first time and characterized in terms of its structure and physicochemical properties. The results showed positive correlations between the polymer's properties, including molecular weight, total phenol content, and ABTS radical scavenging ability, and the dosage of DMY. The polymer exhibited higher inhibitory activity and stability compared to DMY alone, due to its strong protein binding capacity, and also showed superior protective effects on beta-carotene in nano-emulsions stabilized with the DMY-SBP polymers. These findings contribute to our understanding of natural polyphenol-polysaccharide polymers and have implications for the development of new nutraceuticals.

Summary: Dengue, a mosquito-borne disease caused by dengue virus, currently lacks effective and safe therapeutics. This study found that extracts from Antrodia cinnamomea, a precious medical mushroom in Taiwan, exhibited anti-DENV effects by suppressing viral infection and reducing inflammatory cytokine levels. The extracts also increased the levels of the antiviral cytokine interferon-alpha. These findings provide insights into the potential use of A. cinnamomea extracts as therapeutic agents against DENV infection, but further investigation into the underlying mechanisms is needed.

Summary: A new series of quinoline-quinazolinone-thioacetamide derivatives 9a-p were designed and synthesized. These compounds showed significant anti-a-glucosidase activity, with compound 9g being the most potent inhibitor. Molecular simulation studies revealed that compound 9g occupied the active site of a-glucosidase with favorable binding energy. In silico ADMET studies of the most potent compounds predicted their drug-likeness, pharmacokinetic, and toxicity properties.

Summary: This study investigates the efficacy of phytocompounds from whole green jackfruit flour methanol extract (JME) in treating obesity-linked diabetes mellitus using integrated network pharmacology and molecular modeling techniques. It explores the mechanism of action of JME phytocompounds in ameliorating this condition through various analyses and simulations. The study identifies 15 predicted genes and MAPK3 as the most important gene, and suggests that JME phytocompounds could be used for further research in inhibiting MAPK3 for the treatment of obesity-linked diabetes mellitus.

Summary: This study evaluated the impact of consuming toxic sugar bait on the vectorial capacity of Aedes albopictus mosquitoes for dengue virus. It found that while ingestion of the bait increased the mosquito's susceptibility to virus infection and transmission, it also reduced their survival rate, ultimately resulting in a lower predicted vectorial capacity.

Summary: In this paper, a novel three-dimensional constellation diagram is proposed using geometric shaping to optimize the spatial coordinates of constellation points, which leads to improved constellation figure of merit and reduced bit error rate. The performance of the constellation diagram is verified through the implementation of a three-dimensional carrier-free amplitude phase modulated signal transmission on a seven-core fiber communication system. The experimental results demonstrate that this method achieves significant receiver sensitivity gain and reduces bit error rate without additional communication components.

Summary: Recent advances in bound states in the continuum (BICs) are closely related to optically induced Mie and Fabry-Perot resonances in the dielectric supercavity, which exhibit suppressed radiative losses and strong light confinement. By proposing a novel photonic-plasmonic hybrid nanocavity, we can manipulate the mode hybridization resulting from the inter-coupling between photonic and plasmonic Mie-like resonances. This hybrid configuration enables the achievement of quasi-BIC modes, breaking the diffraction limit and enabling large-scale optoelectronic integration.

Summary: This article introduces an anti-turbulence free-space optical communication scheme based on the tunable zero-order Bessel beam. Compared with traditional Gaussian beams, this scheme provides power compensation and maintains communication link stability in poor link environments. To generate tunable Bessel beams, a method based on non-uniform Fourier transform for accurate and fast light field simulation is proposed.

Summary: This paper proposes a new multi-collaboration channel pruning (MCCP) method that evaluates the importance of channels by analyzing the input and output of the batch normalization layer. It combines the weights of the convolution layer and the two learnable parameters of the BN layer to prune channels more reasonably, and introduces polarization regularization to minimize the performance loss of the model.

Summary: An iodine-mediated intramolecular sp3 C-H amination reaction that produces quinazolinone-fused polycyclic skeletons from 2-aminobenzamide precursors is described. The reaction is transition metal-free, has a wide substrate scope, and can be performed on a large scale. By using crude 2-aminobenzamide derivatives, the synthesis of quinazolinone-fused tetrahydroisoquinolines and Rutaecarpine derivatives from easily accessible compounds is possible without purification of the intermediates. Some of the synthesized polycyclic products exhibit inhibitory activity against Cereblon (CRBN) and show potential as anti-myeloma drugs in preliminary biological experiments.

Summary: Crimean-Congo haemorrhagic fever virus (CCHFV) and Hazara virus (HAZV) are genetically and serologically related viruses. Glycosylation analysis of HAZV revealed two N-glycosylation sites in the glycoprotein. However, a panel of iminosugars did not show antiviral efficacy against HAZV. This lack of efficacy may be due to differences in N-linked glycans between the two viruses.

Summary: 2'-Deoxy-2'-β-fluoroadenosines with 4'-azido or 4'-ethynyl groups have been synthesized for the treatment of HIV-1 infection. These compounds exhibit nanomolar anti-HIV-1 activity, with the 4'-ethynyl-2-fluoroadenosine analog 1c (CL-197) being the most potent and least cytotoxic (EC50 = 0.9 nM, CC50 > 100 μM). It shows strong inhibitory activity against drug resistant and clinical HIV-1 strains. Oral administration of 1c in Beagle dogs results in high levels of the bioactive form 1c-TP in peripheral blood mononuclear cells, where it exhibits long-term intracellular retention and prevents HIV-1 infection for an extended time. 1c displays low in vivo toxicity and favorable pharmacokinetic profiles in Sprague-Dawley rats. The preclinical data support the further development of 1c as a highly potent and orally bioavailable clinical candidate for treating HIV-1 infection. Currently, CL-197 is in clinical trials in China (registration number: CXHL2200529).
