The P2X7 receptor is expressed primarily in blood cells such as monocytes, macrophages, and lymphocytes. In addition, the receptor is found in the brain and in the salivary gland. In macrophages, activation of the P2X7 receptor triggers the processing and release of Interleukin 1β (IL-1β). In the immune system, activation of the P2X7 receptor leads to apoptosis. This invention relates to antagonists of the P2X7 receptor, which have high affinity for the receptor and can block ATP-induced toxic processes in blood cells. These antagonists are also useful in preventing apoptosis and Start Printed Page 55416in preventing the release of TNF-α and other inflammatory cytokines such as IL-1β.

The prospective exclusive license will be royalty-bearing and will comply with the terms and conditions of 35 U.S.C. 209 and 37 CFR 404.7. The prospective exclusive license may be granted unless, within 90 days from the date of this published Notice, NIH receives written evidence and argument that establishes that the grant of the license would not be consistent with the requirements of 35 U.S.C. 209 and 37 CFR 404.7.
