Vandetanib inhibits VEGF-, EGF- and bFGF-stimulated HUVECproliferation with IC50 of 60 nM, 170 nM and 800 nM, with no effect on basal endothelial cell growth. Va

Odanacatib is a weak inhibitor of antigenpresentation, measured in a mouse B cell line (IC50=1.50.4 M), compared to the Cat S inhibitor LHVS (IC50=0.001 M) in the same assay. Odanacatib also shows weak inhibition of th
