Application of 19493-44-8, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 19493-44-8, 1-Chloroisoquinoline, introducing its new discovery.
Defining Structure-Functional Selectivity Relationships (SFSR) for a Class of Non-Catechol Dopamine D1 Receptor Agonists
G protein-coupled receptors (GPCRs) are capable of downstream signaling through distinct noncanonical pathways such as beta-arrestins in addition to the canonical G protein-dependent pathways. GPCR ligands that differentially activate the downstream signaling pathways are termed functionally selective or biased ligands. A class of novel non-catechol G protein-biased agonists of the dopamine D1 receptor (D1R) was recently disclosed. We conducted the first comprehensive structure-functional selectivity relationship study measuring GS and beta-arrestin2 recruitment activities focused on four regions of this scaffold, resulting in over 50 analogs with diverse functional selectivity profiles. Some compounds became potent full agonists of beta-arrestin2 recruitment, while others displayed enhanced GS bias compared to the starting compound. Pharmacokinetic testing of an analog with an altered functional selectivity profile demonstrated excellent blood-brain barrier penetration. This study provides novel tools for studying ligand bias at D1R and paves the way for developing the next generation of biased D1R ligands.
