Galectin-3 (Gal-3), a β-galactoside-binding lectin, is implicated in diverse cellular functions ranging from immune response modulation to tissue homeostasis. Notably, increased Gal-3 expression has been linked to the progression of numerous diseases, including cancer, fibrosis, and cardiovascular disorders, underscoring its potential as a therapeutic target. Small molecule inhibitors have been discovered and are valuable tools to study such diseases. We report here the discovery of novel, galactose-based, small molecule inhibitors such as compound 12 which are orally bioavailable and show efficacy in a mouse model of acute liver injury and fibrosis (CCl4 model). The use of structure-based drug design (docking of a virtual library of amides based on acid 2) was key in the process towards potent, nanomolar inhibitors.

Raman-based theranostics has demonstrated great potential for sensitive real-time imaging and treatment. However, these advanced materials, primarily depending on the SERS technique, encounter clinical concerns regarding substrate biosafety. Herein, we molecularly engineered a substrate-free SICTERS small molecule, namely BTT-TPA (bis-thienyl-substituted benzotriazole selenadiazole derivative structures), possessing both ultrasensitive Raman signals and excellent photothermal effects based on self-stacking.

Rechargeable magnesium batteries (RMBs) exhibit significant potential in large-scale energy storage due to their features of high volumetric capacity, resistance to dendrite formation, and abundant magnesium resources. However, the high polarity of divalent Mg2+ ions results in sluggish diffusion kinetics in conventional inorganic cathode materials, adversely affecting reversible capacity and rate performance. Organic materials such as pyrene-4,5,9,10-tetrone (PTO) and 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA), achieve rapid and reversible intercalation of magnesium ions through carbonyl enolization, but these materials are challenged by high cost, complex preparation, and poor environmental friendliness.

The ongoing discovery of highly reactive ambiphilic main-group species has significantly advanced the development of main-group chemistry, particularly in the realms of small molecule activation and catalysis. Theoretically, compounds featuring smaller HOMO-LUMO gaps gain stronger ambiphilicity and higher reactivity. In this work, we fundamentally demonstrate that MeSb holds the smallest HOMO-LUMO gap among trimethylpnictines, indicating its outstanding ambiphilicity.

Postoperative abdominal adhesions are the leading cause of bowel obstruction and a cause of chronic pain and infertility. Adhesion formation occurs after 50 to 90% of abdominal operations and has no proven preventative or treatment strategy. Abdominal adhesions derive primarily from the visceral peritoneum and are composed of polyclonally proliferating tissue-resident fibroblasts.

Uveitis involves a complex interplay of immune cell infiltration and cytokine imbalances, with Th17 cells playing a central role in this process. Th17 cells contribute to disease pathogenesis by promoting inflammation, recruiting additional immune cells, and directly damaging retinal tissues. This review discusses the current knowledge on therapeutic strategies targeting Th17-related cytokines, including cytokine blockade, small molecule inhibitors, and immunomodulatory approaches.
