General description

(S)-(-)-Bay K8644, a dihydropyridine compound is a Ca2+ channel activator.[1] It is an enantiomer of Bay K 8644.[2]

Application

(S)-(-)-Bay K8644 has been used as a L-type calcium channel (LTCC) agonist in the suprachiasmatic nucleus (SCN) slices.[1] It has also been used as a LTCC agonist to induce arrhythmia in rats.[3]

Biochem/physiol Actions

(S)-(-)-Bay K8644 enhances Ca2+ current, whereas the (+)-Bay K 8644 is a weak Ca2+ channel antagonist.[2] Bay K 8644 is lipophilic and it effectively scavenges superoxide anions.[4]
