Descripciòn

LUF7244 is a selective allosteric modulator of K_v11.1 channels. LUF7244 inhibits early afterdepolarizations. LUF7244 can be used for anti-arrhythmia research^[1].

In Vitro

LUF7244 (0-10 μM; HEK293 cells) binds K_v11.1 channels and increases I_Kv11.1 by inhibiting inactivation in a dose-dependent manner^[1].
LUF7244 (0-10 μM; cardiomyocytes) reduces action potential duration (APD) by approximately 50% and dofetilide-induced early afterdepolarization (EAD) in isolated ventricular CMCs from SR and CAVB dogs^[1].
LUF7244 (10 μM) had no effects on I_KIR2.1, I_Nav1.5, I_Ca-L, and I_Ks but doubled I_Kr^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

LUF7244 (2.5 mg/kg; i.v.; for 15 min) decreases repolarization parameters. LUF7244 has antiarrhythmic effects against dofetilide-induced TdP arrhythmias in CAVB dogs^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
