Application

(±)-Bay K8644 has been used as an agonist for voltage sensitive calcium channels (VSCCs) in interneurons, L-type calcium channel (LTCC) in human embryonic kidney 293 cells and viscerofugal neurons.

Biochem/physiol Actions

(±)-Bay K8644 is a 1,4-dihydropyridine (DHP) derivative and an agonist for L-type Ca2+ channels. However, it′s enantiomers (-)-BAY k8644 and (+)-BAY k8644 have opposing functionality with respect to Ca2+ channels as high-potency agonist and low-potency antagonist, respectively. (±)-Bay K8644 increases influx of Ca2+ specifically at voltage-gated calcium channels. It constricts blood vessels and heart contraction.
Increases influx of Ca2+ specifically at voltage-gated calcium channels.
