PNU-120596 is as a potent and selective positive allosteric modulator of α7 nicotinic acetylcholine receptors (nAChRs). It potentiates nAChR α7 currents in Xenopus oocytes and in SH-EP1 cells with EC50 values of 1.6 µM and 216 nM, respectively1-2. The compound displays neuroprotective characteristics in vivo and has the ability to increase the potency and maximal efficacy of agonists and to prolong the duration of the agonist-evoked macroscopic currents1,2.
nAChRs receptors are responsible for mediating the effects of the neurotransmitter acetylcholine (ACh). They play critical roles in the central and peripheral nervous system where they regulate neurotransmitter release, cell excitability, neuronal integration. They are involved in functions such as sleep and arousal patterns, fatigue, hunger, anxiety, and pain processing2,3,4.
PNU-120596 (#P-350) is a highly pure, synthetic, and biologically active compound.
