Cinacalcet (INN) is a drug that acts as a calcimimetic (i.e. it mimics the action of calcium on tissues) by allosteric activation of the calcium-sensing receptor that is expressed in various human organ tissues.
Activating CMKLR1 by an agonist mobilizes intracellular calcium and causes the activation of several other signaling cascades like the ERK1 and NF-κB.
The dual effect of seletracetam is an overall decrease in the amount of action potential due to binding at N-type channels, which prevents over-excitation of the neuron, as well as a decrease in neurotransmitter release as a product of cellular excitation due to the interaction of the drug with SV2A, which reduces the spread of excitation to nearby cells.
