PSD2 Activators

PSD2 activators comprise a diverse group of chemicals that primarily target and activate receptors involved in postsynaptic signaling, particularly within the context of neurotransmission in the central nervous system. This group focuses on the activation of key receptors such as glutamate and GABA receptors, which are essential mediators of excitatory and inhibitory neurotransmission, respectively.

Glutamate receptors, including AMPA and NMDA receptors, are pivotal in excitatory neurotransmission. Chemicals like AMPA, NMDA, Glutamate, Homocysteic acid, Quisqualic acid, and Ibotenic acid serve as agonists to these receptors, mimicking or enhancing the natural excitatory action of glutamate. These activators play significant roles in synaptic plasticity, learning, and memory processes, as they facilitate increased neuronal activity and synaptic strength. NMDA receptors, characterized by their requirement for co-agonists at the glycine binding site, are specifically targeted by compounds like D-Serine, Sarcosine, and Glycine. These co-agonists modulate the receptor function, enhancing its response to glutamate. This modulation is crucial in understanding the complex dynamics of excitatory synaptic transmission and the role of NMDA receptors in neuroplasticity. GABA receptors, including GABA_A and GABA_B, are targeted by agonists like Muscimol, Baclofen, and GABA itself.
