Biological Activity
Cell-permeable sialic acid analog. Deacetylation occurs intracellularly giving rise to a sialyltransferase inhibitor. Abolishes expression of SLex expression on HL-60 cells and reduces E-selectin and P-selectin binding. Prevents metastasis formation in a mouse lung metastasis model.
