Bay K8644 is a chemical compound that functions as an L-typecalcium channelagonist. Bay K8644 is used primarily as a biochemical research tool for this effect.[2] It is a structural analog of nifedipine with positive inotropic activity, and as an aromatic it is highly lipid soluble.
Mechanism of action
Bay K8644 targets L-typevoltage-gatedcalcium channels. It is the first positive inotropic agent shown to act specifically and directly on calcium channels.[3]
