To investigate structure-activity relationships of tankyrase (TNKS) inhibitors, twelve new derivatives of isoquinolin- 1(2H)-one were designed and synthesized, and biological assessments were conducted. Several potent TNKS inhibitors with single- or double-digit nanomolar IC50 values were identified using enzymatic assays. Compound 11c was the most potent compound of this series and inhibited TNKS1 and TNKS2 at an IC50 of 0.009 and 0.003 μM, respectively, and showed an IC50 of 0.029 μM in a DLD-1 SuperTopFlash assay. Molecular docking results showed that compound 11c occupied a unique subpocket and formed a hydrogen bond with Glu1138 of TNKS2, which was not consistent with the patterns of known TNKS inhibitors and thus warrants further research.

Among a series of benzopyridone-based scaffolds investigated as human transient receptor potential vanilloid 1 (TRPV1) ligands, two isomeric benzopyridone scaffolds demonstrated a consistent and distinctive functional profile in which 2-oxo-1,2-dihydroquinolin-5-yl analogues (e.g., 2) displayed high affinity and potent antagonism, whereas 1-oxo-1,2-dihydroisoquinolin-5-yl analogues (e.g., 3) showed full agonism with high potency. Our computational models provide insight into the agonist-antagonist boundary of the analogues suggesting that the Arg557 residue in the S4-S5 linker might be important for sensing the agonist binding and transmitting signals. These results provide structural insights into the TRPV1 and the protein-ligand interactions at a molecular level.

Here we present the synthesis and biological activity of a series of 7-substituted-1-(3-bromophenylamino)isoquinoline-4-carbonitriles as inhibitors of myosin light chain kinase (MLCK) and the epidermal growth factor receptor kinase (EGFR). The inhibitory
