Currently, there are two drugs on the market, gabapentin (Neurontin) and pregabalin (Lyrica), that are proposed to exert their therapeutic effect through binding to the alpha2-delta subunit of voltage-sensitive calcium channels. This activity was unexpected, as the alpha2-delta subunit had previously been considered not to be a pharmacological target. In(More)
Restless legs syndrome (RLS) is a common sensorimotor disorder characterized by abnormal sensations that occur primarily at rest or during sleep, which are alleviated by movement of the affected limb. The pathophysiology of RLS remains unclear, although roles for dopamine dysfunction and brain iron deficiency have been proposed. The hypothalamic A11(More)
Pregabalin is a specific ligand of the alpha2-delta (α2-δ) auxiliary subunit of voltage-gated calcium channels. A growing body of evidence from studies of anxiety and pain indicate that the observed responses with pregabalin may result from activity at the α2-δ auxiliary protein expressed presynaptically, in several different circuits of the central nervous(More)
Several beta-amino tetrazole analogs of gabapentin 1 and pregabalin 2 were prepared by one of two convergent, highly efficient routes, and their affinity for the alpha(2)-delta protein examined. Two select compounds with potent affinity for alpha(2)-delta, 8a and 16a, were subsequently tested in vivo in an audiogenic seizure model and found to elicit(More)
