(R)-(+)-Bay K 8644
Chemical Name: (4R)-1,4-Dihydro-2,6-dimethyl-5-nitro-4-[2-trifluoromethyl)phenyl]-3-pyridinecarboxylic acid methyl ester
Biological Activity(R)-(+)-Bay K 8644 is a L-type Ca2+-channel blocker with negative inotropic and vasodilatatory effects in vivo. Enantiomer showing opposite effects to the racemate (±)-Bay K 8644 (Cat. No. 1544) and (S)-(-)- enantiomer (Cat. No. 1546). Also TMEM176B inhibitor. Induces IL-1β secretion and caspase-1 activation in bone marrow-derived dendritic cells in vitro and increases survival of tumor-bearing mice, both alone and in combination with immune checkpoint blockers.
Racemate and (S)-(-)-Enantiomer also available.
