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 and anti-metastatic activity over related compounds.
摘要:
The invention relates to antibodies that specifically bind a myelorollin comprising an unbranched polylactosamine comprising at least 10 monosaccharides and having terminal .alpha.2.fwdarw.3 sialylation and internal .alpha.1.fwdarw.3 fucosylation at various N-acetylglucosamine residues except the penultimate N-acetylglucosamine residue. The invention also relates to a method of using such antibodies to inhibit E-selectin-dependent rolling of a cell on another cell, wherein one of the cells expresses a myelorollin that binds the antibodies.

An unbranched polylactosamine comprising at least 6 monosaccharides and having terminal .alpha.2.fwdarw.3 sialylation and internal .alpha.1.fwdarw.3 fucosylation at various N-acetylglucosamine residues except for solely at the penultimate N-acetylglucosamine residue.
摘要:
A method of inhibiting tumor cell chemotactic motility and/or chemoinvasion, a method of inhibiting phagokinetic activity of tumor cells and neutrophils, a method of inhibiting tumor cell metastasis and a method of inhibiting inflammation due to motility and invasion into blood vessel walls of neutrophils comprising contacting the cells or administering to a host in need of treatment an inhibitory amount of an agent selected from the group consisting of sphingosine-1-phosphate, derivatives of sphingosine-1-phosphate, and mimetics of the sphingosine-1-phosphate or of the derivatives, and pharmaceutically acceptable salts of the agent. A method of preparing sphingosine-1-phosphate and its derivatives is also described.
