Discovery of potent and selective PKC-θ inhibitors
摘要:
An uHTS campaign was performed to identify selective inhibitors of PKC-theta. Initial triaging of the hit set based on selectivity and historical analysis led to the identification of 2,4-diamino-5-nitropyrimidines as potent and selective PKC-theta inhibitors. A homology model and initial SAR is presented demonstrating that a 2-arylalkylamino substituent in conjunction with suitable 4-diamino substituent are essential for achieving selectivity over many kinases. Additional hit to lead profiling is presented on selected compounds. (c) 2006 Elsevier Ltd. All rights reserved.

are as defined herein, which are useful as inhibitors of PKC-theta and are thus useful for treating a variety of diseases and disorders that are mediated or sustained through the activity of PKC-theta, including immunological disorders and type II diabetes. This invention also relates to pharmaceutical compositions comprising these compounds, methods of using these compounds in the treatment of various diseases and disorders, processes for preparing these compounds and intermediates useful in these processes.
Disclosed are methods and compositions for modulating cancer stem cells. More particularly, the present invention discloses the use of protein kinase C theta inhibitors (PKC-θ) for inhibiting the growth of PKC-θ-overexpressing cells including cancer stem cells, for enhancing the biological effects of chemotherapeutic drugs or irradiation on cancer cells, for treating cancer, including metastatic cancer and/or for preventing cancer recurrence.
