Patent number: 5935940Abstract: 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.Type: GrantFiled: August 5, 1997Date of Patent: August 10, 1999Assignee: Trustees of the University of PennsylvaniaInventor: Paul B. Weisz

Patent number: 5840713Abstract: 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.Type: GrantFiled: September 19, 1995Date of Patent: November 24, 1998Inventor: Paul B. Weisz

Patent number: 5441944Abstract: 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.Type: GrantFiled: September 18, 1992Date of Patent: August 15, 1995Assignee: The Trustees of the University of PennsylvaniaInventors: Paul B.
