General description

A cell-permeable blocker of intracellular calcium release from the sarcoplasmic reticulum that acts by binding to the ryanodine receptor. Inhibits long-term depression and depotentiation of synaptic transmission. Has neuroprotective effects in cases of cerebral ischemia.
A skeletal muscle relaxant. Blocks intracellular calcium release from the sarcoplasmic reticulum during excitation-contraction coupling by binding to the ryanodine receptor. Blocks long-term depression and depotentiation.

mGluR long-term depression (mGluR-LTD) is a form of synaptic plasticity induced at excitatory synapses by metabotropic glutamate receptors (mGluRs). mGluR-LTD reduces synaptic strength and is relevant to learning and memory, autism, and sensitization to cocaine; however, the mechanism is not

Calcium signaling is integral for neuronal activity and synaptic plasticity. We demonstrate that the calcium response generated by different sources modulates neuronal activity-mediated protein synthesis, another process essential for synaptic plasticity. Stimulation of NMDARs generates a protein synthesis response involving
