sFTX-3.3 (100 μM) reduces the duration of the slow component of presynaptic calcium currents by about 50% of the control and also reduces presynaptic sodium current by approximately 20% of the control. sFTX-3.3 (100 μM) reduces whole-cell sodium current recorded from SK.N.SH cells by approximately 15%[3].
