Polyionic derivatives of cyclodextrins and methods for preparing these derivatives are provided in which a polyionic derivative of cyclodextrin is combined with a growth factor, preferably a heparin binding growth factor. These compositions are of low solubility and are applied directly to the location of a wound. By virtue of the low solubility, the compositions remain in place at the site of application and slowly release growth factor. In an alternative embodiment, the cyclodextrin derivatives are administered in the absence of growth factor and are used to absorb growth factor present in the body at the location of the wound in order to prevent overstimulation of the wound response.

Compositions and methods for modulating growth of a tissue in a mammal

Methods of modulating tissue growth and regeneration

The present invention provides polyanionic, substituted CDs having cellular growth modulating-activity. The invention further provides CDs having anionic groups on one side of the CD molecule. Therapeutic methods for using, as well as methods of making the CD compounds of the invention, are also disclosed herein.

Cyclodextrin compounds and methods of making and use thereof

Anti-angiogenic protein composition can be prepared simply and efficiently by contacting cartilage particles containing the protein together with an electrolyte solution and an oligosaccharide bearing a minimum number of anionic substituents per sugar unit, to extract the anti-angiogenic protein from the cartilage particles and to form a complex of the oligosaccharide and the protein. The resultant anti-angiogenic complex can be used for therapeutic treatment of various angiogenic and related diseases.

Anionic saccharides for extraction of anti-angiogenic protein from

Disclosed are methods of therapy applicable to pathologies that involve loss of integrity of tissue and organ membranes that lead to abnormal permeation of proteinic and other agents and their elimination or penetration of other anatomical functions. Such deficiencies are associated directly or indirectly, for example, with inflammatory diseases, with diabetes and others. The therapeutic method involves administering to the membrane in need of treatment a therapeutic amount of an oligosaccharide, preferably a cyclic oligosaccharide, having up to about 10 sugar units per molecule and having at least 1.4 anionic substituents per sugar unit. The anionic substituents are preferably the residues of strong acids.

Therapy for tissue membrane insufficiency

Disclosed are compositions and methods for preventing or substantially inhibiting the hemolytic activity of hemolysis inducing agents. The methods and compositions are based on the use of an anionic oligosaccharide, such as polysulfated cyclodextrin, to achieve the desired reduction in hemolytic active inducing agents.

Prevention of hemolysis

The present invention provides polyanionic, substituted CDs having cellular growth modulating activity. The invention further provides CDs having anionic groups on one side of the CD molecule. Therapeutic methods for using, as well as methods of making the CD compounds of the invention, are also disclosed herein.

Compositions for inhibiting restenosis

Disclosed are compositions and methods effective for inhibiting restenosis. In particular, the present invention provides compositions for inhibiting undesired smooth muscle cell growth or proliferation following angioplasty in mammals, said composition comprising active agents comprising a very water-soluble derivative of cyclodextrin. The invention also provides methods of inhibiting undesired smooth muscle cell growth or proliferation following angioplasty in mammals comprising orally administering to the mammal a growth-inhibiting amount of an active agent comprising a very water-soluble derivative of cyclodextrin.

Methods of inhibiting restenosis

Polyionic derivatives of cyclodextrin polymers and cyclodextrins immobilized on a solid surface are disclosed. Compositions and methods for separating a molecular species, including but not limited to a biologically active protein, from a mixture, for the storage of protein factors and for the therapeutic biodelivery of protein factors which employ the polyionic derivatives of cyclodextrin polymers and cyclodextrins immobilized on a solid surface are also disclosed.

Cyclodextrin polymers and cyclodextrins immobilized on a solid surface

Disclosed are compositions and methods for prevented or substantially inhibiting the hemolytic activity of hemolysis inducing agents. The methods and compositions are based on the use an anionic oligosaccharide, such as polysulfated cyclodextrin, to achieve the desired reduction in hemolytic active inducing agents.

The invention relates to highly water soluble substituted .alpha.-, .beta.- or .gamma.-cyclodextrin sulfates associated with a physiologically acceptable cation. Pathological or otherwise undesirable cell or tissue growth in mammals, including humans, is inhibited by administering thereto (1) a water-soluble substituted cyclodextrin sulfate salt, together with (2) a growth-inhibiting organic compound. The growth-inhibiting compound (2) may be asteroid having no inhibiting effect in the absence of (1), or an organic compound which may be an active growth inhibitor, the action of which is potentiated by (1). The invention provides a method for inhibiting angiogenesis and controlling the growth of tumors as well as treating other diseases and pathological conditions associated with undesired cell or tissue growth, including angiogenesis.
