We report on the identification of a novel small molecule inhibitor of anthrax lethal factor using a high-throughput screening approach. Guided by molecular docking studies, we carried out structure-activity relationship (SAR) studies and evaluated activity and selectivity of most promising compounds in in vitro enzyme inhibition assays and cellular assays. Selected compounds were further analyzed for their in vitro ADME properties, which allowed us to select two compounds for further preliminary in vivo efficacy studies. The data provided represents the basis for further pharmacology and medicinal chemistry optimizations that could result in novel anti-anthrax therapies.

Electrochemical carbon dioxide reduction reaction (CO2RR) to highly value-added C2+ fuels or chemicals is a promising pathway to address environment issues and energy crisis. In the periodic table, Cu as only the candidate can convert CO2 to C2+ products such as C2H4 and C2H5OH due to the suitable absorption energy to reaction intermediate. Application of Cu is limited for its low activity and poor selectivity.

Cryptosporidiosis is a diarrheal disease caused by the parasite resulting in over 100,000 deaths annually. Here, we present a structure-activity relationship study of the benzoic acid position (R) of pyrazolo[3,4-]pyrimidine lead SLU-2815 (), an inhibitor of parasite phosphodiesterase PDE1, resulting in the discovery of benzoxaborole SLU-10906 () as a benzoic acid bioisostere. Benzoxaborole is 10-fold more potent than against the parasite in a cell-based infection model (EC = 0.

Electrocatalytic synthesis of high-value chemicals has been attracting growing interest owing to its environmentally benign reaction pathways. Among these processes, the electrocatalytic reduction of nitrate (NO3-) to ammonia (NH3), known as NO3RR, and the oxidation of 5-hydroxymethylfurfural (HMFOR) stand out as two cornerstone reactions; yet, their efficiency and selectivity pose ongoing challenges. In this study, we introduce a charge manipulation approach for the design of highly efficient electrocatalysts tailored for the simultaneous coupling of NO3RR and HMFOR.

Bisindole alkaloids constitute a significant class of natural compounds distinguished by their characteristic bisindole structure and renowned for their anticancer properties. Over the past six decades, researchers have isolated 425 microorganism-derived bisindole alkaloids (MDBAs). Among them, 187 MDBAs have demonstrated anticancer properties against various in vitro cancer cell lines, primarily by impeding the cell cycle, restraining cell proliferation, and inducing apoptosis and autophagy.

β-lactams have been the most successful antibiotics, but the rise of multi-drug resistant (MDR) bacteria threatens their effectiveness. Serine β-lactamases (SBLs), among the most common causes of resistance, are classified as A, C, and D, with numerous variants complicating structural and substrate spectrum comparisons. This study compares representative SBLs of these classes, focusing on the substrate-binding pocket (SBP).
