Minimalistic 2-(oxazolinyl)-phenols substituted with different electron-donating and -withdrawing groups as well as 1,2,5-chalcogenadiazole-annulated derivatives thereof were synthesized and investigated in regard to their emission behavior in solution as well as in the solid state. Depending on the nature of the incorporated substituent and its position, emission efficiencies were increased or diminished, resulting in AIE or ACQ characteristics. Single-crystal analysis revealed J- and H-type packing motifs and a so-far undescribed isolation of ESIPT-based fluorophores in the keto form.

Transcriptional enhancer associated domain family members (TEADs) are the most important downstream effectors that play the pivotal role in the development, regeneration and tissue homeostasis. Recent biochemical studies have demonstrated that TEADs could undergo autopalmitoylation that is indispensable for its function making the lipid-binding pocket an attractive target for chemical intervention. Herein, through structure-based virtual screen and rational medicinal chemistry optimization, we identified DC-TEADin02 as the most potent, selective, covalent TEAD autopalmitoylation inhibitor with the IC50 value of 197 ± 19 nM while it showed minimal effect on TEAD-YAP interaction. Further biochemical counter-screens demonstrate the specific thiol reactivity and selectivity of DC-TEADin02 over the kinase family, lipid-binding proteins and epigenetic targets. Notably, DC-TEADin02 inhibited TEADs transcription activity leading to downregulation of YAP-related downstream gene expression. Taken together, our findings proved the validity of modulating transcriptional output in the Hippo signaling pathway through irreversible chemical interventions of TEADs autopalmitoylation activity, which may serve as a qualified chemical tool for TEADs palmitoylation-related studies in the future.

Introduction of an alkylcarboxylic acid unit, which is a partial structure of endogenous peroxisome proliferator-activated receptor (PPAR) ligands, into a phenethylphenylphthalimide skeleton, which possesses liver X receptor (LXR) antagonistic activity, afforded novel PPAR ligands. The results of structure-activity relationship analysis and docking studies led us to the potent PPAR agonists 13c-e. The absolute configuration of 13c-e affects the PPAR subtype selectivity.
