38 results about "CXCR4 antagonist" patented technology

A CXCR4 antagonist is a substance which blocks the CXCR4 receptor and prevent its activation. Blocking the receptor stops the receptor's ligand, CXCL12, from binding which prevents downstream effects. CXCR4 antagonists are especially important for hindering cancer progression because one of the downstream effects initiated by CXCR4 receptor activation is cell movement which helps the spread of cancer, known as metastasis. The CXCR4 receptor has been targeted by antagonistic substances since being identified as a co-receptor in HIV and assisting the development of cancer. Macrocyclic ligands have been utilised as CXCR4 antagonists.

Identification of allosteric peptide agonists of CXCR4

The chemokine receptor CXCR4 is a co-receptor for T-tropic strains of HIV-1. A number of small molecule antagonists of CXCR4 are in development, but all are likely to lead to adverse effects due to the physiological function of CXCR4. To prevent these complications, allosteric agonists may be therapeutically useful as adjuvant therapy in combination with small molecule antagonists. A synthetic cDNA library coding for 160,000 different SDF-based peptides was screened for CXCR4 agonist activity in a yeast strain expressing functional receptor. Peptides that activated CXCR4 in an autocrine manner induced colony formation. Two peptides, designated RSVM and ASLW, were identified as novel agonists that are insensitive to the CXCR4 antagonist AMD3100. In chemotaxis assays using the acute lymphoblastic leukemia cell line CCRF-CEM, RSVM behaves as a partial agonist and ASLW as a superagonist. The superagonist activity of ASLW may be related to its inability to induce receptor internalization. In CCRF-CEM cells, the two peptides are also not inhibited by another CXCR4 antagonist, T140, or the neutralizing monoclonal antibodies 12G5 and 44717.111. These results suggest that alternative agonist binding sites are present on CXCR4 that could be screened to develop molecules for therapeutic use.
