Uses
(
S)-(-)-Bay K8644 has been used as a L-type calcium channel (LTCC) agonist in the suprachiasmatic nucleus (SCN) slices. It has also been used as a LTCC agonist to induce arrhythmia?in rats.
Definition
ChEBI: (S)-Bay-K-8644 is a methyl 2,6-dimethyl-5-nitro-4-[2-(trifluoromethyl)phenyl]-1,4-dihydropyridine-3-carboxylate in which the 4-position has (S)-configuration. It is an enantiomer of a (R)-Bay-K-8644.
General Description
(
S)-(-)-Bay K8644, a dihydropyridine compound is a Ca
2+?channel activator. It is an enantiomer of Bay K 8644.
Biological Activity
L-type Ca 2+ -channel activator with positive inotropic, vasoconstrictive and behavioral effects in vivo . Enantiomer of (1,4-Dihydro-2,6-dimethyl-5-nitro-4-[2-(trifluoromethyl)phenyl]-3-pyridinecarboxylic acid, methyl ester ).
Biochem/physiol Actions
(S)-(-)-Bay K8644 enhances Ca2+ current, whereas the (+)-Bay K 8644 is a weak Ca2+ channel antagonist. Bay K 8644 is lipophilic and it effectively scavenges superoxide anions.
