Pullulans having active sites formed by sulfation, phosPhorylation, sulfonation or carboxylation or their pharmacologically acceptable salts, wherein one hydrogen atom of the active sites represented by formula (I), partially sub- stituted by a group represented by the general formula (II), (wherein L1 and L2 each represents amine or unidentate amine or when taken together, represent bidentate amine. and Y represents an anionic ligand) and/or two hydrogen atoms or the active sites represented by formula (III) or of two formula (IV) groups bound to the same carbon atom or adjacent carbon atoms are partially substituted by a group represented by the formula (V), (wherein L' and L2 are the name as defined above). These compounds have an onco- static activity and are useful as oncostatic agents. Process for their preparation and their medicinal use are also dis- closed
