Description
Curator's Comment: description was created based on several sources, including: http://adisinsight.springer.com/drugs/800031959 | https://www.ncbi.nlm.nih.gov/pubmed/25113756

Ipatasertib (LCL161) binds to inhibitors of apoptosis proteins (IAPs) with high affinity and initiates the destruction of cIAP1 and cIAP2, which further induces apoptosis via caspase activation. Ipatasertib is advancing in clinical development including five Phase 2 trials in patients with Breast cancer, Multiple myeloma, Myelofibrosis, Small cell lung cancer and Ovarian cancer. The most common LCL161-related adverse events were nausea and vomiting.

LCL161 showed antiproliferative effects and reduced cell viability significantly in Hep3B (IC50 10.23 uM) and PLC5 (IC50 19.19 uM) cells in a dosedependent manner. However, Sk-Hep1 (IC50 223.55 uM) and Huh-7 cells (IC50 227.77 uM) showed resistance to LCL161 as measured by cell viability.
