Abstract
En 中文
Positive allosteric modulators bind to secondary binding sites on the receptor and alter receptor conformation and activation, changing agonist potency and efficacy. PTC-174 is a novel NMDA receptor positive allosteric modulator that particularly enhances activity of receptors containing GluN2C or GluN2D subunits. We have investigated potentiation by PTC-174 of dopaminergic neuron NMDA responses, where receptors are likely to be GluN1/GluN2B/GluN2D triheteromeric receptors.
