PSD2 Inhibitors

PSD2 inhibitors, in the context of this discussion, represent a diverse set of chemicals primarily tailored to modulate or influence postsynaptic signaling. These compounds target various receptors and channels present at the postsynaptic membrane to regulate synaptic activity. The rationale behind the selection is rooted in the understanding of synapse biology. For instance, glutamate receptors such as AMPA and NMDA are pivotal in excitatory neurotransmission. Chemicals like NBQX and D-AP5 are antagonists of these receptors, effectively inhibiting excitatory postsynaptic potentials. On the contrary, GABA receptors, like GABAA and GABAB, mediate inhibitory neurotransmission.

Bicuculline and Phaclofen act as antagonists for these receptors, disrupting inhibitory signaling. Moreover, ion channels play a crucial role in maintaining the ionic balance and generating action potentials. TTX and Nimodipine, which block sodium and calcium channels respectively, can profoundly impact synaptic function. Another dimension of postsynaptic regulation involves intracellular signaling cascades. U73122, for example, hinders the phospholipase C pathway, crucial for various cellular processes including those at the synapse. These inhibitors collectively underscore the intricate and multifaceted nature of synaptic signaling and the myriad ways it can be modulated.
