The genus Salvia L. (Lamiaceae) comprises myriad distinct medicinal herbs, with terpenoids as one of their major active chemical groups. Abietane-type diterpenoids (ATDs), such as tanshinones and carnosic acids, are specific to Salvia and exhibit taxonomic chemical diversity among lineages. To elucidate how ATD chemical diversity evolved, we carried out large-scale metabolic and phylogenetic analyses of 71 Salvia species, combined with enzyme function, ancestral sequence and chemical trait reconstruction, and comparative genomics experiments. This integrated approach showed that the lineage-wide ATD diversities in Salvia were induced by differences in the oxidation of the terpenoid skeleton at C-20, which was caused by the functional divergence of the cytochrome P450 subfamily CYP76AK. These findings present a unique pattern of chemical diversity in plants that was shaped by the loss of enzyme activity and associated catalytic pathways.

In this study, a comprehensive genome-wide identification and analysis of the aldo-keto reductase (AKR) gene family was performed to explore the role of Gossypium hirsutumAKR40 under salt stress in cotton. A total of 249 AKR genes were identified with uneven distribution on the chromosomes in four cotton species. The diversity and evolutionary relationship of the cotton AKR gene family was identified using physio-chemical analysis, phylogenetic tree construction, conserved motif analysis, chromosomal localization, prediction of cis-acting elements, and calculation of evolutionary selection pressure under 300 mM NaCl stress.

Bacterial persisters are a subpopulation of cells that exhibit a transient non-susceptible phenotype in the presence of bactericidal antibiotic concentrations. This phenotype can lead to the survival and regrowth of bacteria after treatment, resulting in relapse of infections. It is also a contributing factor to antibacterial resistance.

Soybean saponins, a class of intricate oleanane-type triterpenoids predominantly present in soybeans, exhibit diverse biological activities. This overview summarizes recent progress in elucidating the biological roles of soybean saponins and their glycosides, encompassing anti-inflammatory, antimutagenic, anticancer, and antimicrobial effects, viewed through a tectonic lens. Additionally, it explores modification methodologies encompassing physical, chemical, and biological strategies.

Carbon-11 (C)-labeled radiotracers are invaluable tools in positron emission tomography (PET), enabling real-time visualization of biochemical processes with high sensitivity and specificity. Among the various C synthons, cyclotron-produced [C]CO is a fundamental precursor, though its direct incorporation into complex molecules has traditionally been limited by its low reactivity, gaseous form, and short half-life. Recent advances in [C]CO fixation chemistry through both nonphotocatalytic and photocatalytic methods have significantly expanded its utility in the synthesis of structurally diverse compounds, including carboxylic acids, carbonates, carbamates, amides, and ureas.

Drug-induced hepatotoxicity (DIH), characterized by diverse phenotypes and complex mechanisms, remains a critical challenge in drug discovery. To systematically decode this diversity and complexity, we propose a multi-dimensional computational framework integrating molecular structure analysis with disease pathogenesis exploration, focusing on drug-induced intrahepatic cholestasis (DIIC) as a representative DIH subtype. First, a graph-based modularity maximization algorithm identified DIIC risk genes, forming a DIIC module and eight disease pathogenesis clusters.
