Originally identified as a substrate (ChA or choline)-noncompetitive, slowly reversible choline acetyltransferase inhibitor (human ChAT/BuChE/AChE IC₅₀ = 88 nM/33.3 µM/48.6 µM; does not affect mAChRs, AChE, ChE, CrAT, ganglionic or skeletal muscular nAChRs), α-NETA is a fluorescent molecule (Ex 255 & 297 nm; Em 427 nm) also known for its trace amine-associated receptor 5 (TAAR5 EC₅₀ = 150 nM) agonist and chemokine-like receptor-1 antagonist (IC₅₀ = 375 nM; 7 nM chemerin-induced CMKLR1 β-ARR2 recruitment) potencies both in cultures and in animal disease models in vivo (3-20 mg/kg via ip. or sc. in rats & mice).
