4. Uses of Lomeguatrib
Lomeguatrib is a Inhibitor of MGMT. It is a potent pseudosubstrate inhibitor, and to define a suitable dose of temozolomide to be used in combination with lomeguatrib in patients with advanced cancer. Some studies show that this first administration of lomeguatrib to man successfully established an oral ADD of lomeguatrib and identified a combination regimen with temozolomide suitable for future clinical evaluation. In addition, it is a Alkylguanine Alkyltransferase Inhibitor.
