Glycodendrimers coated with N-acetyl-glucosamine and labeled with a fluorescent dye demonstrate special tropism to neogenerated endothelia in cancer capillaries. Same distribution was observed by confocal microscopy in the new vessels of rat embryo abdominal wall, as in placenta and yolk sack endothelia. Results suggests the presence of a commun target on evoluting endothelia, the nature of which is under investigation.

Masking oligosaccharide sequences can assist transformed cells to escape immune surveillance. N-acetyl-glucosamine coated dendrimers have binding affinity for NKR-P1 receptor and can also modify cancer cell glycosylation profile. Effects of treatment on immune cell subpopulations were analyzed in blood, lymphoid tissues and organs, and inside tumor in B16F10 melanoma bearing mice. Treatment enhanced tumor cell immunogenicity, and induced maturation,differentiation and homing of cytotoxic cells to tumor microenvironment.
