It is a blocker of voltage-sensitive K⁺ channels with potent convulsant activity.

Mast cell degranulating activity: it causes histamine release with half-maximal effects in rat peritoneal mast cell preparations at concentrations of 2 X 10^-8 M.
MCD Peptide binds with high affinity (K_d = 150 pM) to rat synaptic membranes. This binding induces the inhibition of a voltage sensitive K⁺ current and produces hippocampal responses (long term potentiation, Theta rhythm and epileptiform seizures).

Reconstitution recommendations: 125 μl of distilled water added to a 50 μg vial gives a 100 μM MCD Peptide solution.
Store preferably at -20 °C. The solution can be freezed and thawed.
