Replacement of the pentyl chain on our original bicyclo[2.2.2]octyltriazole leads 1 and 2 has led to the discovery that heteroaryl substituted bicyclo[2.2.2]octyltriazoles are potent and selective 11beta-hydroxysteroid dehydrogenase type I (11beta-HSD1) inhibitors with excellent pharmacokinetic profiles.

The development of phosphorylation-suppressing inhibitors targeting Signal Transducer and Activator of Transcription 3 (STAT3) represents a promising therapeutic strategy for non-small cell lung cancer (NSCLC). In this study, a generative model was developed using transfer learning and virtual screening, leveraging a comprehensive dataset of STAT3 inhibitors to explore the chemical space for novel candidates. This approach yielded a chemically diverse library of compounds, which were prioritized through molecular docking and molecular dynamics (MD) simulations.

Mirror-image proteins, composed of D-amino acids, are an attractive therapeutic modality, as they exhibit high metabolic stability and lack immunogenicity. Development of mirror-image binding proteins is achieved through chemical synthesis of D-target proteins, phage display library selection of L-binders and chemical synthesis of (mirror-image) D-binders that consequently bind the physiological L-targets. Monobodies are well-established synthetic (L-)binding proteins and their small size (~90 residues) and lack of endogenous cysteine residues make them particularly accessible to chemical synthesis.

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.

Bioorthogonalized light-responsive click-and-uncage platform has enabled precise cell surface engineering and timed payload release, but most of such photoactivatable prodrugs have "always-on" photoactivity leading to the dark toxicity. On the other hand, the conditionally activatable photocage is limited to the application of fluorogenic probe/photosensitizer liberation. Herein, we devise a conditionally activatable theranostic platform based on the tetrazine (Tz)-boron-dipyrromethene (BODIPY) construct, in which tetrazine serves as a quencher motif to disable both the fluorescence and photoresponsivity of BODIPY.
