Figure 5: AChE impairing by selective inhibitors: Ach = AcTChI as a substrate without inhibitors; Ach + i = AcTChI + 10−4 M iso-OMPA, selective inhibitor of pseudocholinesterase (BChE, E.C.; Ach + e = AcTChI + 10−4 M eserin, mainly inhibitor of AChE; Ach + BW = AcTChI + 10−4 M BW284c51, selective inhibitor of AChE. Eserin was used only once, for controls. No specificity control was performed on PChE activity. -axis = micromoles of substrate cleaved in 3 mins.
