Frame-Shifted Synthesis of Oligoheterocycles as a Platform for Molecular Design. [PDF]

open access: yesAngew Chem Int Ed Engl
Modern chemistry seeks to turn the simple raw materials into complex molecules that matter in health, agriculture, and technology. Among these, oligoheterocycles stand out for their versatility, yet they are most often built by cross‐coupling reactions that often rely on expensive metal catalysts.

Discovery of a First‐in‐Class Covalent Allosteric SHP1 Inhibitor with Immunotherapeutic Activity

open access: yesAngewandte Chemie, EarlyView.
A covalent allosteric inhibitor M029 was discovered for SHP1, a novel target for immunotherapy. M029 binds to a cryptic Cys remote from the active site, exhibits robust target engagement, and blocks tumor progression by stimulating antitumor immune response.
