Summary: In this study, a low-molecular-weight dual-action linear polymer is used to successfully inhibit different strains of influenza A virus. The optimized polymer targets both hemagglutinin and neuraminidase on the virus surface, leading to effective inhibition of virus propagation. The polymer is significantly more effective than the commercial drug zanamivir, demonstrating its translational potential for broad and high antiviral efficacy.

Summary: Introducing structurally diverse benzyl side chains at the C5-NH2 position of oseltamivir improves its binding affinity with neuraminidase and anti-influenza activity. We designed and synthesized novel oseltamivir derivatives with different N-heterocycle substituents that induce opening of the 150-loop of group-2 neuraminidases. Compound 6k showed broad-spectrum activity against wild-type neuraminidases and enhanced activity against H3N2 compared to oseltamivir carboxylate and zanamivir.

Summary: In this study, a universal swine H3 influenza vaccine was designed using a computational algorithm, which showed significant cross-reactive antibody and T-cell responses in both murine and swine models. The vaccine demonstrated superior cross-reactive immunity and reduced weight loss and lung viral titers in mice challenged with different swH3 viruses. The findings suggest that this epigraph vaccination strategy should be further investigated as a potential universal swH3 vaccine.

Summary: This study reports the development of a novel engineered cyclotide with effective broad-spectrum antibacterial activity against several ESKAPE bacterial strains and clinical isolates. The most active antibacterial cyclotide was extremely stable in serum, showed little hemolytic activity, and provided protection in vivo in a murine model of P. aeruginosa peritonitis. These results highlight the potential of the cyclotide scaffold for the development of novel antimicrobial therapeutic leads for the treatment of bacteremia.

Summary: Antiretroviral therapy can inhibit HIV-1 replication but cannot cure the infection due to the persistence of a reservoir in the host genome. Reduction of this reservoir is important for HIV-1 cure. Some nonnucleoside reverse transcriptase inhibitors have shown selective cytotoxicity against HIV-1 in vitro, but their concentrations required are much higher than approved dosages. By focusing on this secondary activity, researchers have discovered bifunctional compounds called targeted activators of cell kill (TACK) that can kill HIV-1-infected cells at clinically achievable concentrations. These TACK molecules bind to the reverse transcriptase-p66 domain of monomeric Gag-Pol and act as allosteric modulators, promoting dimerization and premature intracellular viral protease activation, leading to death of HIV-1(+) cells. TACK molecules retain potent antiviral activity and selectively eliminate infected CD4(+) T cells, providing a potential immune-independent clearance strategy.

Summary: This study reveals the origin of Li2S2-Li2S reduction catalysis in single-atom materials based on ferromagnetic elements, attributing it to the spin density and magnetic moments. Experimental and theoretical studies show that Fe-N-4-based cathodes exhibit the fastest deposition kinetics of Li2S and the lowest thermodynamic energy barriers. Accelerated Li2S2-Li2S reduction catalysis enabled via spin polarization provides practical opportunities for long-life batteries.

Summary: Tuning the microenvironment and electronic structure of support materials is a crucial strategy in catalytic kinetics optimization. This study synthesized molybdenum oxycarbide supported Rh-clusters with modulated interstitial C-O microenvironments to enhance hydrogen evolution in water splitting. The apparent charge transfer from Rh to MoOC was observed, optimizing the electronic structure and improving hydrogen-evolving activity. The presence of interstitial C and O atoms in MoOC supports also played a vital role in the water dissociation reaction. The Rh/MoOC catalyst exhibited exceptional hydrogen-evolving activities, surpassing benchmark commercial Rh/C catalysts in both alkaline and acidic media.

Summary: Bone regenerative biomaterials are important for treating bone defects by mimicking the extracellular matrix and creating a favorable environment for cell attachment, proliferation, and differentiation. However, the currently used materials often have high stiffness, which can lead to difficulties in degradation and increase the risk of foreign body ingestion. This study developed soft fibrous scaffolds modified with Zn-MOF-74 nanoparticles to address these issues and promote osteogenic differentiation of stem cells, resulting in successful bone regeneration in a rat femoral defect model.

Summary: We constructed an extracellular vesicles (EVs)-cloaked enzymatic nanohybrid (ENEV) as a multifaceted biocatalyst for ultrasound (US)-augmented tendon matrix reconstruction and immune microenvironment regulation. The ENEV-based biocatalyst effectively removed reactive oxygen species (ROS) and released Zn2+ ions, facilitated cellular uptake with US, and induced immune regulation with EVs. In a rat Achilles tendon defect model, the ENEVs combined with US treatment promoted functional recovery and matrix reconstruction, suppressed scarring and adhesion, and offered an alternative strategy for tissue regenerative therapies.
