Patent number: 5696147Abstract: Synthetic mammalian matrix metalloprotease inhibitors are useful in controlling angiogenesis. These compounds are thus useful in controlling the growth of tumors and in controlling neovascular glaucomas.Type: GrantFiled: December 3, 1993Date of Patent: December 9, 1997Assignee: Glycomed, Inc.Inventor: Richard E. Galardy

Patent number: 5380716Abstract: Highly sulfated oligosaccharides in the form of hexasaccharide and octasaccharide compounds which have antiproliferative activity with respect to smooth muscle cells are useful in treatment of conditions characterized by unwanted smooth muscle cell proliferation such as a result of trauma or disease states such as asthma, congestive heart failure and hypertension. The oligosaccharides have increased ability to inhibit the proliferation of smooth muscle cells and decreased ability to act as an anticoagulant as compared with commercial heparin and/or unseparated fragments of heparin.Type: GrantFiled: December 28, 1992Date of Patent: January 10, 1995Assignee: Glycomed, Inc.Inventors: H. Edward Conrad, Peter Fugedi, Brian K. Brandley, Lun H. Lam, Roger A. Laine

Patent number: 5138044Abstract: Reaction schemes for carrying out a variety of chemical synthesis are disclosed. The reactions produce .alpha.-(X)-sialosides wherein X is O, S, N or another compatible electron donating atom or molecular moiety. The reaction schemes include a relatively small number of steps to provide a yield with a relatively small amount of undesired .beta.-configuration product. Compounds synthesized are encompassed by the following general structural formula I. ##STR1## wherein R, R' and R" are each independently H, CH.sub.3, acetyl, or a disaccharide which is preferably lactose.Type: GrantFiled: August 13, 1990Date of Patent: August 11, 1992Assignee: Glycomed, Inc.Inventor: Falguni Dasgupta

Patent number: 5094731Abstract: Saccharide in mixtures are separated into groups or individual saccharides and tested for their affinity for particular proteins. The method of the invention is carried out by conjugating saccharides in a mixture with charge-generating moieties and moieties capable of fluorescing such as 4-amino-1-naphthalene sulfonic acid (ANSA) to form conjugates. The saccharide conjugates are subjected to electrophoretic resolution within gels. The resolved bands of material can be seen under ultraviolet light and are electro-blotted onto charged nylon membranes to provide a stable record of the electrophoretic separation. The blots (visible under ultraviolet light) on the nylon membranes are brought into contact with particular proteins in order to determine the binding affinity of these particular proteins to particular saccharides on the nylon membrane. The proteins are preferably bound to labels so that the binding of the proteins to the saccharides can be easily detected.Type: GrantFiled: September 27, 1990Date of Patent: March 10, 1992Assignee: Glycomed, Inc.Inventors: Brian K. Brandley, Paul G. James, Michael Tiemeyer

Patent number: 5094740Abstract: Separation methodology is disclosed which allows for the separation of mixtures of carbohydrates into highly resolved detectable bands of carbohydrates. The method involves first reacting a mixture of carbohydrates with charge generating moieties which are capable of fluorescing such as 1-amino-4-naphthalene sulfonic acid (ANSA) to form carbohydrate conjugates. The conjugates are subjected to a first-dimensional gel electrophoresis in a first direction to provide separate bands of carbohydrates in the gel. A band in the gel is removed and subjected to second-dimensional electrophoresis in a second direction which is substantially perpendicular to the first direction. More specific bands of more highly resolved carbohydrates are then formed in the second-dimensional gel. The more specific bands within the second-dimensional gel are then electro-blotted onto a substrate surface and can be viewed in extremely small amounts due to the fluorescent capability of the ANSA when viewed under ultraviolet light.Type: GrantFiled: September 27, 1990Date of Patent: March 10, 1992Assignee: Glycomed, Inc.Inventors: Brian K. Brandley, Robert J. Stack

Patent number: 5087337Abstract: A method of separating mixtures of saccharides into distinct detectable groups is disclosed. In accordance with the method a tri-functional conjugate must first be provided. The tri-functional conjugate is obtained by reacting a mixture of saccharides with moieties (a) capable of providing a charge upon ionization; (b) capable of fluorescing under ultraviolet light; and (c) having a light-activatable azido group thereon. The different functional moieties may all be present on the same moiety and connected directly to the saccharide or may be connected to each other wherein only one of the moieties is connected directly to the saccharide. The tri-functional conjugates are subjected to electrophoretic separation to obtain separate groups of conjugates in the gel. The groups of conjugates are transferred from the gel to the surface of a membrane which is exposed to light for a sufficient time and light frequency to activate the azido-group.Type: GrantFiled: September 27, 1990Date of Patent: February 11, 1992Assignee: Glycomed, Inc.Inventors: Brian K. Brandley, Michael Tiemeyer, Robert J. Stack

Patent number: 5053406Abstract: Compositions useful in the prevention and treatment of rotaviral infections are disclosed. The subject compositions contain cholesterol 3-sulfate or functional derivatives thereof. Cholesterol 3-sulfate avidly binds rotavirus in thin layer overlay assays and inhibits rotavirus in plaque reduction assays. These compositions can be used to prevent and ameliorate rotaviral infections.Type: GrantFiled: December 13, 1989Date of Patent: October 1, 1991Assignee: Glycomed, Inc.Inventors: Cherly Srnka, Roger A. Laine, James Gilbert
