Small-molecule inhibitors of the interaction between TNF and TNFR

摘要

The overexpression of TNF has been implicated in a variety of disease conditions including rheumatoid arthritis, Crohns disease, HIV and cancer. It is presently a therapeutic target for inflammatory diseases. Many of the therapeutics currently used are biologics designed to sequester TNF, preventing it from binding with its receptors. Recent research has been focused on finding small molecules that alter the production of TNF, modulate its signal transduction pathways, or directly inhibit the binding to its receptors. Modulation of a protein-protein interaction with small molecules is an interesting and nontrivial approach. The various strategies used in obtaining small-molecule, nonpeptide, inhibitors of the TNF-TNF receptor interaction through disruption of the TNF trimer or direct inhibition of the TNF-TNF receptor interaction are presented here.
