Lidocaine 15-24 immunoglobulin lambda variable 2-18 Homo sapiens 247-255 22565935-10 2012 The effect of ranolazine on mechanosensitivity of Na(V)1.5 was approximated by lidocaine. Lidocaine 79-88 immunoglobulin lambda variable 2-18 Homo sapiens 50-58 20173760-4 2010 RESULTS: MFA and lidocaine inhibited human Na(V)1.5 channels expressed in Xenopus oocytes in a positive rate-dependent and concentration-dependent manner, with IC(50) values of 72.61 micromol/L and 145.62 micromol/L, respectively. Lidocaine 17-26 immunoglobulin lambda variable 2-18 Homo sapiens 43-51 22874086-10 2012 Lidocaine inhibited mechanosensitivity in Na(V)1.5 at the local anesthetic binding site mutated (F1760A). Lidocaine 0-9 immunoglobulin lambda variable 2-18 Homo sapiens 42-50 17070808-1 2006 Molecular modeling predicts that a local anesthetic (LA) lidocaine binds to the resting and open Na(v)1.5 in different modes, interacting with LA-sensing residues known from experiments. Lidocaine 57-66 immunoglobulin lambda variable 2-18 Homo sapiens 97-105 15485686-10 2004 CONCLUSIONS: These findings suggest that the Na(v)1.5/V1763M channel dysfunction and possible neighboring mutants contribute to a persistent inward current due to altered inactivation kinetics and clinically congenital LQTS with perinatal onset of arrhythmias that responded to lidocaine and mexiletine.
