IC50 and IC70 values for fucosylation inhibitors calculated by AAL lectin flow cytometry.

Compound	IC50 PC3	IC50 CWR22RV1	IC70 PC3	IC70 CWR22RV1
DMSO	N.I	N.I	N.I.	N.I.
A2FF1P	16.26	7.575	29.43	21.15
B2FF1P	26.92	12.86	48.73	31.86
2FF	113.5	25.68	207.0	63.79
Fucotrim I	0.1510	N.D.	0.7560	N.D.
Fucotrim II	29.17	26.96	N.D.	N.D.

N.I = no inhibition. N.D = not determined since the measured values did not reach a reduction to 50% respectively 70% in lectin binding.
