A non-saccharide glycosaminoglycan mimetic molecule comprising a polyproline backbone and one or more non-saccharide molecules, wherein the non-saccharide molecules are bound to one or more prolines and/or proline derivatives on the polyproline backbone, is disclosed herein. In a preferred embodiment the non-saccharide molecule is a negatively charged sulfate. The invention also relates to methods of synthesizing said non-saccharide glycosaminoglycan mimetic molecule and the use of the molecules thereof in targeting cell adhesion molecules such as selectin.
