16881015-4	2006	The effects of the five alkaloids on human red blood cell (RBC) acetylcholinesterase (AChE) and human plasma butyrylcholinesterase (BChE) were further studied, and their IC (50) values for human RBC AChE were 6.4 +/- 0.003 microM, 16.9 +/- 0.018 microM, 5.7 +/- 0.004 microM, 6.5 +/- 0.013 microM and 7.7 +/- 0.001 microM, respectively, and the IC50 values for human plasma BChE were 12.5 +/- 0.026 microM, 2.1 +/- 0.005 microM, 5.2 +/- 0.002 microM, 7.3 +/- 0.005 microM and 0.7 +/- 0.001 microM, respectively.
