BuChE-IN-6 (compound 1b) is a highly effective and specific inhibitor of BuChE (butyrylcholinesterase), demonstrating an IC50 value of 0.46 μM for eqBuChE and 0.51 μM for hBuChE. Furthermore, BuChE-IN-6 has the additional capability of inhibiting the self-aggregation of Aβ 42 [1].
BuChE-IN-5 (compound 25b) is a highly potent BuChE inhibitor, displaying an IC50 value of 1.94 μM. It effectively inhibits aggregation of Aβ and tau protein in Escherichia coli. Furthermore, BuChE-IN-5 exhibits considerable free radical scavenging capacity and antioxidant activity. Given these properties, it holds promise as a valuable tool for Alzheimer's disease research [1].
