Calciseptine is a natural polypeptide toxin found in the venom of the black mamba snake (Dendroaspis p. polylepis). Calciseptine is a highly effective and selective blocker of the L-type channel of the Cav1.2 subtype, with an IC50 value of 92 nM. Calciseptine has no effect on Cav3.1, Cav2.2, Cav2.1, Cav1.1, voltage-sensitive sodium channels and potassium channels. Calciseptine exhibits negative inotropic and negative relaxant effects on mice, and does not affect heart rate or the action potential of sinoatrial node pacemaker cells. Calciseptine can be used for research on cardiovascular diseases[1].

Sarafotoxin S6d (STX-b) is a polypeptide toxin isolated from the venom of the Israeli sand boa constrictor. Sarafotoxin S6d induces multiple electrocardiogram (ECG) changes including myocardial ischemia and hyperkalemia. Sarafotoxin S6d induces strong extracellular calcium-dependent vasoconstriction in rat aorta and exhibits positive inotropic effects in rat atria. Sarafotoxin S6d can be used in the study of cardiovascular diseases .
