'''Crystal Structure of TNF-alpha with a small molecule inhibitor'''<br />
'''Crystal Structure of TNF-alpha with a small molecule inhibitor'''<br />


==Overview==
==Overview==
We have identified a small-molecule inhibitor of tumor necrosis factor, alpha (TNF-alpha) that promotes subunit disassembly of this trimeric, cytokine family member. The compound inhibits TNF-alpha activity in, biochemical and cell-based assays with median inhibitory concentrations of, 22 and 4.6 micromolar, respectively. Formation of an intermediate complex, between the compound and the intact trimer results in a 600-fold, accelerated subunit dissociation rate that leads to trimer dissociation. A, structure solved by x-ray crystallography reveals that a single compound, molecule displaces a subunit of the trimer to form a complex with a dimer, of TNF-alpha subunits.
