UN-No:
Non-Hazardous - /

Poziotinib is a potent inhibitor of EGFR family kinases with IC50 values of 3.2, 5.3, 23.5, 4.2, and 2.2 nM for wild-type EGFR, HER2, HER4, EGFRT790M, and EGFRL858R/T790M, respectively.{38157} It has greater than 100- to 1,000-fold selectivity for EGFR kinases over 30 other tested kinases in vitro. Poziotinib inhibits growth of wild-type and mutant EGFR kinase-dependent lung, breast, and gastric cancer cell lines (GI50s = 0.6-5.7 nM) and inhibits EGFR phosphorylation and induces apoptosis in vitro. In vivo, poziotinib reduces tumor size in an HCC827 non-small cell lung cancer mouse xenograft model. Formulations containing poziotinib are under investigation in clinical trials for the treatment of EGFR-mutant lung adenocarcinoma.{38158}

    The maintenance of embryonic stem cells in culture typically requires feeder cells and various exogenous factors found in serum. Murine embryonic stem (mES) cells can be maintained in the absence of feeder cells and serum but require the leukemia inhibitor factor (LIF) and bone morphogenic protein (BMP) to prevent differentiation and promote self-renewal.
