PSEM 89S TFA is a brain-penetrant and selective ion channels agonist, and is orthogonally selective for Q79G and L141F, respectively.

Neurotoxin that blocks neuromuscular transmission via irreversible inhibition of nicotinic ACh receptors (nAChRs). Prevents opening of nicotinic receptor-associated ion channels and is selective for α7 receptors over α3β4 receptors (IC50 values are 1.6 nM and > 3 μM respectively).

TAE-1 is an inhibitor of amyloid-β fibril formation and aggregation. It inhibits cholinesterases AChE and BuChE with IC50 of 0.3 μM and 3.9 μM, respectively.
