Johnson Solid Gold Nanoclusters as Heterogeneous Visible-Light Photocatalysts for Fukuyama Indole Synthesis.

Despite notable advancements in noble metal photocatalysis, improving catalyst efficiency and recyclability remains a key challenge that needs to be addressed to facilitate large-scale synthetic applications. Herein, we have successfully synthesized bisphosphine-protected gold nanoclusters with a distinctive Johnson solid kernel, which serve as efficient and recyclable heterogeneous photocatalysts for visible-light-driven three-component radical couplings in Fukuyama indole synthesis. In contrast to conventional gold complexes, the newly developed cluster-based catalysts can be easily photoexcited to their triplet states by visible light, enabling single-electron transfer with -acyl oximes, a hitherto unexplored class of electrophiles in gold photocatalysis.

Association Between Size of Left Ventricle and Long-Term Cardiovascular Events.

Background: The prognostic significance of small left ventricle (LV) in the general population and its association with cardiovascular disease remain elusive.

Methods: Using data from the UK Biobank, 39 363 participants underwent baseline cardiovascular magnetic resonance imaging and were categorized into 3 groups based on left ventricular end-diastolic volume index: small, normal, and large LV. Cox proportional hazards models were applied to evaluate the association between LV size and composite cardiovascular outcomes.

ST6GAL1 promotes IBD B cell recruitment to the inflamed colon in a CD22-dependent mechanism.

Background And Aims: Since the discovery that auto-reactive anti-αvβ6 integrin antibodies are associated with ulcerative colitis, cells from the B cell lineage, especially plasmablasts and plasma cells have increasingly come into the focus of research on inflammatory bowel disease. However, the mechanisms regulating their recruitment from the circulation to the gut remain poorly understood. Here, we explored whether the B cell-specific lectin CD22 interacts with endothelial α2,6-linked sialic acid residues attached by ST6GAL1 to mediate such recruitment in IBD.

Construction, structural modification, and bioactivity evaluation of pentacyclic triterpenoid privileged scaffolds in active natural products.

Pentacyclic triterpenoids, as important representatives of natural products, have garnered widespread attention due to their diverse biological activities, including anti-inflammatory, antiviral, and antitumor effects. Oleanolic acid (OA), betulinic acid (BA), ursolic acid (UA), triptolide, and glycyrrhetinic acid (GA) are typical examples of pentacyclic triterpenoids. Despite their significant biological activities, their poor water solubility and low bioavailability have limited further development and application.

Stable and Recyclable Copper Nanoclusters with Exposed Active Sites for Broad-Scope Protosilylation in Open Air.

Despite recent advances in cluster-based catalysis for organic synthesis, the substrate scope of reactions catalyzed by metal nanoclusters is typically not superior to previously established catalytic systems. Herein, we develop new atomically precise copper nanoclusters for protosilylation, with scope expanding to alkenes and simple enynes that were not suitable for prior synthetic methodologies with traditional copper complexes. The involvement of a second copper center in the metal kernel during the migratory insertion step is thought to be responsible for the expanded scope.

Targeting both ferroptosis and pyroptosis may represent potential therapies for acute liver failure.

In this editorial, we comment on the article published in the recent issue of the . Acute liver failure (ALF) is a fatal disease that causes uncontrolled massive hepatocyte death and rapid loss of liver function. Ferroptosis and pyroptosis, cell death forms that can be initiated or blocked concurrently, can play significant roles in developing inflammation and various malignancies.

Yishen Tongbi decoction attenuates inflammation and bone destruction in rheumatoid arthritis by regulating JAK/STAT3/SOCS3 pathway.

Background: Yishen-Tongbi Decoction (YSTB), a traditional Chinese prescription, has been used to improve syndromes of rheumatoid arthritis (RA) for many years. Previous research has shown that YSTB has anti-inflammatory and analgesic properties. However, the underlying molecular mechanism of the anti-RA effects of YSTB remains unclear.

NIR-II emissive anionic copper nanoclusters with intrinsic photoredox activity in single-electron transfer.

Ultrasmall copper nanoclusters have recently emerged as promising photocatalysts for organic synthesis, owing to their exceptional light absorption ability and large surface areas for efficient interactions with substrates. Despite significant advances in cluster-based visible-light photocatalysis, the types of organic transformations that copper nanoclusters can catalyze remain limited to date. Herein, we report a structurally well-defined anionic Cu nanocluster that emits in the second near-infrared region (NIR-II, 1000-1700 nm) after photoexcitation and can conduct single-electron transfer with fluoroalkyl iodides without the need for external ligand activation.

A novel mutation in hERG gene associated with azithromycin-induced acquired long QT syndrome.

Background: Mutations in human ether-à-go-go-related gene (hERG) potassium channels are closely associated with long QT syndrome (LQTS). Previous studies have demonstrated that macrolide antibiotics increase the risk of cardiovascular diseases. To date, the mechanisms underlying acquired LQTS remain elusive.

Synthesis and pharmacological activity of vinpocetine derivatives.

Vinpocetine and its derivatives were extensively employed in the treatment of ischemic stroke, serving as effective cerebrovascular vasodilators. They could also be utilized for neuroprotection, anti-inflammatory purposes, anti-aging interventions, insomnia treatment, and antidepressant effects. However, due to issues such as hepatic first-pass effect, low bioavailability, and poor patient compliance with multiple dosing, the secondary development of Vinpocetine to address these limitations became a prominent area of research.

2D Ni-Co bimetallic oxide nanosheets activate persulfate for targeted conversion of bisphenol A in wastewater into polymers.

The selective removal of targeted pollutants from complex wastewater is challenging. Herein, a novel persulfate (PS)-based advanced oxidation system equipped with a series of two-dimensional (2D) bimetallic oxide nanosheets (NSs) catalysts is developed to selectively degrade bisphenol A (BPA) within mixed pollutants via initiating nonradical-induced polymerization. Results indicate that the NiCoO NSs demonstrate the highest catalytic efficiency among all Ni-Co NSs catalysts.

Etrolizumab-s fails to control E-Cadherin-dependent co-stimulation of highly activated cytotoxic T cells.

Despite promising preclinical and earlier clinical data, a recent phase III trial on the anti-β7 integrin antibody etrolizumab in Crohn's disease (CD) did not reach its primary endpoint. The mechanisms leading to this outcome are not well understood. Here we characterize the β7 T cell compartment from patients with CD in comparison to cells from individuals without inflammatory bowel disease.

Blocking GPR15 Counteracts Integrin-dependent T Cell Gut Homing in Vivo.

Background And Aims: The G protein coupled receptor GPR15 is expressed on and functionally important for T cells homing to the large intestine. However, the precise mechanisms by which GPR15 controls gut homing have been unclear. Thus, we aimed to elucidate these mechanisms as well as to explore the potential of targeting GPR15 for interfering with T cell recruitment to the colon in inflammatory bowel disease [IBD].
