摘要:
The present invention is directed toward the delivery of toxic agents to pathogenic cells, particularly cancer cells. In some embodiments, the toxic agent is a human ribonuclease or similar agent that is toxic to cells.
摘要:
The present invention relates generally to conjugates of human ribonucleases and water-soluble polymers, compositions comprising the conjugates and methods of using the same. In particular, the present invention provides conjugates of human ribonucleases and one or more water-soluble polymer compositions (e.g., to increase serum half-life and a pharmacokinetic profile, in vivo biological activity, stability, and/or reduce host immune response to the protein in vivo) as well as methods of using the conjugates in the therapy, treatment, and/or prevention of disease (e.g., cancer).
摘要:
The present invention is directed toward the delivery of a toxic protein to pathogenic cells, particularly cancer cells. In preferred embodiments, the toxic protein is a ribonuclease that has been modified to make it toxic to target cells and that can be conjugated to a target cell-specific delivery vector, such as an antibody, for delivery to pathogenic cells.
摘要:
This invention provides multivalent ligands which carry or display at least one recognition element (RE), and preferably a plurality of recognition elements, for binding directly or indirectly to cells or other biological particles or more generally by binding to any biological molecule. Provided are methods for inducing cellular chemotaxis by introducing a multivalent ligand having at least one N-formyl or N-acyl peptide as a signal recognition element. The signal recognition elements are bound to a molecular scaffold that is a ring-opening metathesis polymerization scaffold. In these scaffolds, the number, spacing, relative positioning and relative orientation of signal recognition elements can be controlled.
