Biological Activity

[Description]:

Almokalant is a class III antiarrhythmic drug, acts as a potassium channel blocker, and inhibits a specific component (Ikr) of the time-dependent delayed rectifier K+ current.

[Target]

Potassium channel[1]


[In Vitro]

Almokalant is a class III antiarrhythmic drug, acts as a potassium channel blocker, and inhibits a specific component (Ikr) of the time-dependent delayed rectifier K+ current[1].

[In Vivo]

Almokalant (125 μmol/kg, p.o.) induces cardiovascular defects, orofacial clefts, and tail defects in pregnant rats, after administration on Day 11. Almokalant also causes in pregnant rats[1].
