α-NETA is a potent and noncompetitive choline acetyltransferase (ChA) inhibitor with an IC50 of 9 μM. α-NETA is a potent ALDH1A1 (IC50=0.04 µM) and chemokine-like receptor-1 (CMKLR1) antagonist. α-NETA weakly inhibits cholinesterase (ChE; IC50=84 µM) and acetylcholinesterase (AChE; IC50=300 µM). α-NETA has anti-cancer activity.

How to use

In Vitro:

α-NETA (50-150 nM; 24 hours) decreases all cell lines viability in a dose-dependent manner. α-NETA (2.5-10.0 µg/mL; 24 hours) leads to epithelial ovarian cancer (EOC) cell death associated with membrane blistering and cytoplasm leakage. α-NETA treatment increases EOC cell expression of pyroptosis-associated proteins. α-NETA is most potent in inhibiting aldehyde dehydrogenase 1 family, member A1 (ALDH1A1; IC50=0.04 µM; purified enzymes assay), followed by CMKLR1 (IC50=0.375 µM for β-ARR2 recruitment; Cell-based assay) and G9a histone lysine methyltransferase (IC50=0.50 µM; purified enzymes assay). α-NETA selectively inhibits chemerin-stimulated CMKLR1 association with β-arrestin2. α-NETA possesses fluorescent characteristics (excitation spectrum: maxima 255 and 297 nm; emission spectrum: maximum 437 nm) of naphthyl moiety.

In Vivo:

α-NETA (i.p.; 0.125 mg/kg; once every other day for 20 days) significantly decreases tumor volume and tumor weight. α-NETA (s.c. injection; 3 mg/kg or 10 mg/kg; daily; for 30 days) significantly delays the onset of EAE with 3 mg/kg, and completely suppresses clinical signs for an average of nine days with 10 mg/kg beyond the first appearance of disease in control female C57BL/6 mice.
