Phenanthridinones are important heterocyclic frameworks present in a variety of complex natural products, pharmaceuticals and displaying wide range of pharmacological actions. Its structural importance has evoked a great deal of interest in the domains of organic synthesis and medicinal chemistry to develop new synthetic methodologies, as well as novel compounds of pharmaceutical interest. This review focuses on the synthesis of phenanthridinone scaffolds by employing aryl-aryl, -aryl, and biaryl coupling reactions, decarboxylative amidations, and photocatalyzed reactions.

Aim: The continuous update of international guidelines and enhanced availability of biological disease-modifying antirheumatic drugs (bDMARDs) and targeted synthetic DMARDs (tsDMARDs) have made a significant impact on the diagnosis and treatment of early rheumatoid arthritis (ERA). This study aims to systematically evaluate the current treatment strategies and outcomes within a large-scale cohort of patients with ERA.
Methods: Data from the Chinese Registry of Rheumatoid Arthritis (CREDIT), a large multicenter Chinese registry of RA, were collected to analyze temporal trends in clinical profiles, therapeutic strategies, and treatment outcomes among patients with ERA.

Background: The climate crisis and depleting fossil fuel reserves have led to a drive for 'green' alternatives to the way we manufacture chemicals, and the formation of a bioeconomy that reduces our reliance on petrochemical-based feedstocks. Advances in Synthetic biology have provided the opportunity to engineer micro-organisms to produce compounds from renewable feedstocks, which could play a role in replacing traditional, petrochemical based, manufacturing routes. However, there are few examples of bio-manufactured products achieving commercialisation.

To achieve a long cycle life and high-capacity performance for Li-O batteries, it is critical to rationally modulate the formation and decomposition pathway of the discharge product LiO. Herein, we designed a highly efficient catalyst containing dual catalytic active sites of Pt single atoms (Pt) paired with high-entropy alloy (HEA) nanoparticles for oxygen reduction reaction (ORR) in Li-O batteries. HEA is designed with a moderate d-band center to enhance the surface adsorbed LiO intermediate (LiO(ads)), while Pt active sites exhibit weak adsorption energy and promote the soluble LiO pathway (LiO(sol)).

Synthetic polymers have found widespread use with functional lifetimes from seconds to decades. However, the lack of end-of-life treatment for these plastics is causing a significant environmental and human health crisis due to their persistence and bioaccumulation. Upcycling post-consumer plastic waste to products with inherent recyclability is an attractive strategy to tackle this problem, as it can broaden the range of accessible materials and uncover unprecedented features while dealing with current plastic waste.

Alzheimer's disease (AD) is an irreversible neurodegenerative disorder that poses a significant risk to human health and well-being. The high cost and invasiveness of neuroimaging and cerebrospinal fluid (CSF) analysis underscores the necessity for accessible early screening via blood samples. In this study, we developed an ultrasound-based strategy for emergent macroscopic that enhances the acoustic response enrichment of specific proteins by introducing functionalized microspheres.
