CL-13 is an inhibitor of butyrylcholinesterase (BChE), exhibiting an IC50 of 1.15 μM and a selectivity index (SI) of 9.2 for acetylcholinesterase. It demonstrates antioxidative activity in SH-SY5Y cells with a DPPHEC50 of 47.01 μM and has the capacity to chelate metals involved in Aβ aggregation and/or oxidative stress, showing no neurotoxicity at concentrations up to 50 μM. CL-13 can also reverse scopolamine-induced cognitive impairments without affecting motor abilities in mice.
