Table 2. IC₅₀ values of biologically active oligosaccharides and FGFR and EGFR-2 inhibitors in endothelial cell migration assay.

Oligosaccharide/RTKi	FGF2		VEGF165
	µg/ml	µM	µg/ml	µM
8-mer 2SNS	2.86	1.2	ND	ND
9-mer 2SNS	2.11	0.83	9.17	3.6
10-mer 2SNS	0.30	0.1	3.54	1.2
12-mer 2SNS	0.38	0.11	0.58	0.17
PD173074	-	0.082	ND	ND
SU4312	ND	ND	-	0.19

The mean of at least two independent experiments is represented. No more than 2-fold differences between IC₅₀s in two independent experiments were observed. ND - not determined; RTKi – receptor tyrosine kinase inhibitor.
