Biased modulators of NMDA receptors control channel opening and ion selectivity

Allosteric modulators of ion channels typically alter the transitions rates between conformational states without changing the properties of the open pore. Here we describe a new class of positive allosteric modulators of N-methyl d-aspartate receptors (NMDARs) that mediate a calcium-permeable component of glutamatergic synaptic transmission and play essential roles in learning, memory and cognition, as well as neurological disease.
