Chemical Structure
L-735821
- CAS No.: 170228-29-2
- Formula:C25H19Cl2N3O2
- Molecular Weight:464.34
IUPAC Name: (R,E)-3-(2,4-dichlorophenyl)-N-(1-methyl-2-oxo-5-phenyl-2,3-dihydro-1H-benzo[e][1,4]diazepin-3-yl)acrylamide
InChIKey: BYULDQRRUINTAA-SWDTZWKESA-N
SMILES: O=C(/C=C/C1=CC=C(C=C1Cl)Cl)N[C@H]2C(N(C3=CC=CC=C3C(C4=CC=CC=C4)=N2)C)=O
Biological Activity: L-735821 is a Potassium channel blocker and an antagonist of IKs. L-735821 inhibits the KCNQ1 channel activity with an EC50 of 0.08 μM. L-735821 can increase IKs and IKr current-voltage relations in rabbit ventricular myocytes. L-735821 fully abolishes IKs in isolated human ventricular myocytes at 100 nmol/L. L-735821 can easily enter single myocytes[1][2][3][4].
