G-protein-coupled receptor (GPCR) ligands impart differing degrees of signaling in the G-protein and arrestin pathways, in phenomena called "biased signaling". However, the mechanism underlying the biased signaling of GPCRs is still unclear, although crystal structures of GPCRs bound to the G protein or arrestin are available. In this study, we observed the(More)
Antitumor activity of N-heterocyclic carboxaldehyde thiosemicarbazone derivatives was examined in ascites sarcoma-180 system. Among isoquinoline-1-carboxaldehyde thiosemicarbazone derivatives, the parent compound, IQ-1, was the most active and less toxic. On the other hand, among the pyridine-2-carboxaldehyde thiosemicarbazone derivatives tested,(More)
