A facile strategy for the synthesis of isoxazoles has been efficaciously developed, which involves oxidation of propargylamines to the corresponding oximes followed by CuCl-mediated intramolecular cyclization of the latter. This protocol shows a straightforward way to construct a series of isoxazole cores with a wide range of functional group compatibility. Meanwhile, a gram-scale experiment and synthetic applications can be successfully operated.

Background: Owing to their extensive utilization as pesticides, heterocycles assume a fundamental role in the management of vector-borne diseases. Despite the presence of numerous heterocyclic compounds in commercial insecticides and larvicides, resistance to pesticides still demands novel strategies to current pest control methods. Considering these facts, this review aims to survey the synthesis and SAR of heterocyclic molecules with larvicidal activity against Aedes aegypti Linn.

Dynamic communication between hepatocytes and the environment is critical in hepatocellular carcinoma (HCC) development. Clinical immunotherapy against HCC is currently unsatisfactory and needs more systemic considerations, including the identification of new biomarkers and immune checkpoints. Transmembrane 4 L six family member 5 (TM4SF5) is known to promote HCC, but it remains unclear how cancerous hepatocytes avoid immune surveillance and whether avoidance can be blocked.

Background: Hyperbaric Oxygen Therapy (HBO) is a treatment modality that exposes patients to 100% oxygen at higher atmospheric pressures. Recently, HBO has emerged as a potential therapeutic option for various liver diseases, offering advantages such as improved tissue oxygenation, anti-inflammatory effects, enhanced wound healing, and potential hepatoprotective properties. Understanding the benefits of HBO in liver diseases can pave the way for novel therapeutic strategies and improved patient outcomes.

A 6-step gram-scale synthesis of the fungal polyketide (±)-gregatin A is described. The synthetic route features an intermolecular 1,3-dipolar cycloaddition, a Mo-mediated disconnection of the isoxazole skeleton, and an acid-mediated deprotection/enamine hydrolysis and hemiketalization cascade.

Neuroinflammation and the immune response are recognized as significant mechanisms contributing to the progression and pathophysiology of Parkinson's disease (PD). Consequently, extensive research is being conducted on drugs targeting inflammation and immune response. Leflunomide, known for its anti‑inflammatory and immunomodulatory properties, is currently used as a disease‑modifying agent for the treatment of rheumatoid arthritis.
