Mechanism Of Action and Pharmacodynamic Effects Click here for help
The phosphatidylinositide 3-kinase family is involved in various aspects of cellular homeostasis and is deregulated in a number of pathophysiologic conditions. As a result, inhibitors of this kinase family are keenly investigated as therapeutics for immunological, cardiac and cancer indications. PI-103 inhibits angiogenesis, cell invasion, and metastasis, and has direct antiproliferative effects [3,7-8].
