| 产品描述： | Bax 选择性抑制剂 | 活化剂 | 调节剂;Bax Selective Inhibitors | Activators | Modulators;;InformationBTSA1 is a pharmacologically optimizedBAXactivator that binds with high affinity and specificity to the N-terminal activation site and induces conformational changes to BAX leading to BAX-mediated apoptosis. It effectively promotes apoptosis in leukemia cell lines and patient samples while sparing healthy cells.TargetsBaxIn vitroBTSA1 has no capacity to directly activate the pro-apoptotic homolog BAK. BTSA1 treatment potently and dose-responsively induces membrane translocation of recombinant soluble BAX to mitochondrial membrane, which is followed by induction of BAX oligomerization. BTSA1-induced BAX activation promotes apoptosis in cancer cells. BTSA1 reduces viability of all AML cell lines in a dose-dependent manner with IC50 values ranged between 1 and 4 μM, which leads to complete effect within 24 hr treatment. It induces dose-dependent caspase-3/7 activation in all five AML cell lines.In vivoBTSA1 potently suppresses human acute myeloid leukemia (AML) xenografts and increases host survival without toxicity. It is well-tolerated in mice with no toxic effects on healthy hematopoiesis, including healthy stem cellenriched (LSK) cells, common myeloid progenitors, granulocyte-monocyte progenitors, and megakaryocyte-erythrocyte progenitors. BTSA1 has substantial half-life in mouse plasma (T1/2 = 15 hr) and oral bioavailability (%F = 51), while a 10 mg/kg dose reaches sufficient levels (~15 μM) of BTSA1 to induce BAX activation and apoptosis in leukemia cells. Thus, BTSA1 is orally bioavailable with excellent pharmacokinetics, has significant anti-tumor activity in leukemia xenografts by promoting apoptosis, and at therapeutically effective doses it does not show any detectable toxicity in the hematopoietic system or other tissues.Cell Research(from reference)Cell lines：AML cells Incubation Time：2.5 hr |
