General description

A cell-permeable 4-anilino quinazoline compound that acts a potent, reversible, and ATP-competitive inhibitors of EGFR and c-erbB2 (IC50 = 20 nM and 79 nM, respectively), members of the type I growth factor receptor family that is involved in breast cancer development and progression. Shown to effectively inhibit the proliferation (IC50 = ~ 1.2-2.5 µM) of tumor cells overexpressing EGRF or c-erbB-2.
A cell-permeable, potent, reversible, and ATP-competitive inhibitor of the tyrosine kinase activity of EGFR (IC50 = 20 nM) and c-erbB2 (IC50 = 79 nM), members of the type I growth factor receptor family implicated in the development and progression of various forms of cancer, including breast and small lung cell carcinoma. Shown to effectively inhibit the proliferation (IC50 ~1.2-2.5 µM) of tumor cells overexpressing EGRF or c-erbB-2.

Song control nuclei have distinct sexual differences in songbirds. However, the mechanism that underlies the sexual differentiation of song nuclei is still not well understood. Using a combination of anatomical, pharmacological, genetic, and behavioral approaches, the present study investigated the
