Abstract: A variety of human adenocarcinomas express sialylated, fucosylated Lewis blood group antigens on cell surface and secreted mucins. Binding of these antigens to P-selectin on platelets is thought to facilitate formation of platelet-tumor emboli in the circulation, which in turn allows sequestration of the tumor cells in the microvasculature. Here we report a pharmacologic approach for blocking these interactions through metabolic inhibition of sialylation. Peracetylated forms of Gal␤1,4GlcNAc␤-O-naphthalenemet…
