1262618-39-2 Usage

Uses

GS967, also known as GS-458967, is a highly selective late sodium channel current blocker. The selective inhibition of late INa with GS967 can exert antiarrhythmic effects by suppressing EAD- and DAD-mediated extrasystolic activity in PFs and PV and SVC sleeve preparations. Selective late INa inhibition with GS967 exerts potent protective effects against ischemia-induced depolarization and repolarization abnormalities in both atria and ventricles.

Biological Activity

gs967 is a potent, selective and novel inhibitor of cardiac late sodium current (late ina) with ic50=0.13 μm in ventricular myocytes and ic50=0.21μm in isolated hearts. [1]when na+ channels in myocytes fail to inactivate after opening, na+ influx continues throughout the ap plateau. the resulting na+ current (ina) is referred to as late ina. its magnitude is increased in many pathologic conditions, such as in the failing and/or ischemic heart, in the heart exposed to oxidative stress, and in hearts of patients with congenital long qt3 syndromes. [1]in rabbit isolated ventricular myocytes, inhibition of peak ina by gs967 is in a concentration- and voltage-dependent manner with minimal use-dependent, it also decreases the na+ and ca2+ overload. in rabbit-isolated heart, gs967 abolishes tdp induced by atx-ii or e-4031. [1]in anesthetized rabbit, gs967 reduces mapd90 but did not alter cardiac conduction time; it also prevents the induction of arrhythmic activity and tdp by clofilium and decreases the incidence of ischemia-induced arrhythmias.

Check Digit Verification of cas no

The CAS Registry Mumber 1262618-39-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,6,1 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1262618-39:
(9*1)+(8*2)+(7*6)+(6*2)+(5*6)+(4*1)+(3*8)+(2*3)+(1*9)=152
152 % 10 = 2
So 1262618-39-2 is a valid CAS Registry Number.
