Description: Bay K 8644, a dihydropyridine compound, is a specific L-type Ca2+ channel agonist. Bay K 8644 increases Ca2+ influx through sarcolemmal Ca2+ channels by increasing the open time of the channel[1].
In Vivo: A one time dose as low as 10 μg/kg of Bay K 8644 significantly elevates mean arterial pressure (MAP) in endotoxin-treated hypotensive rats while having minimal effects in normal rats. Bay K 8644 also causes a dose-dependent decrease in heart rate of 37% in endotoxin-treated rats and 39% in control rats[1].
In Vitro: In newborn rat ventricular cardiomyocytes, Bay K 8644 (1 μM) treatment increases L-type calcium current density in 2-day-old cells. The higher increase of L-type calcium current density by Bay K 8644 in 2-day- than in 7-day-old cultured cells could be interpreted as the result of a difference in the phosphorylation level of calcium channels for each stage of development[2].
