摘要:
Systematic chemical analysis of glycosphingolipid (GSL) fractions from large quantities of normal human neutrophils and HL60 cells failed to detect GSL's which are binding targets of selectin. A series of long-chain, unbranched polylactosamine GSL's with a terminally sialylated, internally polyfucosylated structure bind selectins.

A vaccine and method to prevent growth and replication of cancer cells that express a core structure of a mucin-type glycoprotein is disclosed. The vaccine comprises: (a) a pharmaceutically effective amount of an antigen comprising a purified mucin-type glycoprotein or a chemically synthesized mucin-type glycoprotein carbohydrate determinant conjugated to a carrier peptide or macromolecule, wherein said mucin-type glycoprotein expresses or carries the core structure of a mucin-type glycoprotein expressed on said cancer cells; and (b) a pharmaceutically acceptable carrier including natural or synthetic adjuvants. The method comprises administering the above-described vaccine to a host. A medicament and method for treating cancer wherein the cancer cells express a core structure of a mucin-type glycoprotein is disclosed. The medicament comprises: (a) a pharmaceutically effective amount of an anti-cancer antibody or fragment comprising a binding site thereof, said anti-cancer antibody having been produced against a purified core structure of a mucin-type glycoprotein; and (b) a pharmaceutically acceptable carrier, diluent or excipient. The method comprises administering the above-described medicament to a host.
摘要:
A vaccine and method to prevent or to retard the growth and replication of cancer cells that express a carbohydrate wherein the vaccine comprises: (a) a pharmaceutically effective amount of a carbohydrate antigen found on said cancer cells, or a mimetic thereof; and (b) a pharmaceutically acceptable carrier. The carbohydrate antigen can be Tn or sialyl-Tn.

摘要:
The invention relates to a novel compound, compositions and medicaments thereof and a method of inhibiting cell proliferation, platelet aggregation (induced by various factors) and inhibiting malignant phenotypes of tumor cells such as those having a metastatic property, and modulating cell adhesion molecule expression and function using said compound, composition or medicament. N,N,N-trimethylsphingosine shows superior cell proliferation inhibitory an anti-metastatic activity over related compounds.
