Abstract Camptothecin (CPT), a plant‐derived monoterpene indole alkaloid first identified in Camptotheca acuminata, is a drug precursor widely used for cancer chemotherapeutics. However, the full set of genes responsible for CPT biosynthesis remains unclear, hindering efforts to elucidate the complete pathway or establish biosynthetic production of CPT

Enhancing IR‐MALDESI MSI Spatial Resolution Through Beam Constriction With a Ring‐Actuated Iris
ABSTRACT Rationale Infrared matrix‐assisted laser desorption electrospray ionization (IR‐MALDESI) mass spectrometry imaging (MSI) enables label‐free, spatially resolved molecular analysis of biological tissues under ambient conditions. While improving spatial resolution is important for mapping fine tissue structures, mid‐infrared (IR) lasers are ...

ω‐Hydroxy and ω‐oxo acids are precursors to lactones, polyesters, and nylon‐6, yet selective interconverting enzymes remain scarce. Clostridium viride supplies two iron alcohol dehydrogenases: Cvir‐Hbd2, restricted to C4, and the genomic singleton Cvir‐Hvd, spanning C5–C12 substrates.

Fragmentation of the natural product vancoresmycin reveals an essential role of global architecture for biological potency. Vancoresmycin is a structurally complex tetramic‐acid‐containing natural product with potent activity against Gram‐positive bacteria, yet its structure–activity relationships remain poorly defined.

This study firstly isolated a tuna‐derived gut probiotic Acinetobacter seifertii YFT067. Dietary administration of YFT067 played significant roles in promoting growth performance, SCFAs production, lipid absorption, and metabolism of the host, indicating YFT067 as a promising probiotic candidate for enhancing tuna aquaculture productivity through ...

Using an integrated strategy of network pharmacology and transcriptomics, this study elucidates the therapeutic mechanism of XuanShi Choudong Recipe (CDR) against tic disorder (TD). CDR dose‐dependently alleviates apomorphine‐induced tic‐like stereotypy and hyperlocomotion in rats, restores striatal neurotransmitter homeostasis, and attenuates ...

Unlocking Stereodefined Olefins by Z‐Selective Transition Metals‐catalyzed C−H Activations
The synthesis of Z‐olefins is an important challenge in synthetic organic chemistry. Within this review, we report a comprehensive overview of transition metals‐catalyzed Z‐selective C–H activations of (hetero)arenes for the synthesis of stereodefined olefins.
