(±)-Bay K 8644
L-type Ca2+ channel activator (EC50 = 17.3 nM). Has positive inotropic, vasoconstrictive and behavioral effects in vivo. Separate enantiomers (R)-(+)-Bay K 8644 and (S)-(-)-Bay K 8644 also available (Cat. Nos. 1545 and 1546 respectively). In combination with BIX-01294 (Cat. No. 3364), helps generate induced pluripotent stem cells (iPSCs) from mouse embryonic fibroblasts (MEFs). Inhibits autophagy.
