Cat. No. 3590
Chemical Name: (2Z)-2-Methyl-4-[(1R,3aS,5S,11R,14a
Biological ActivityApoptosis inducer in several tumor cell lines including T47D cells. Activates caspases (EC50 values are 0.78 - 1.64 μM) and competitively inhibits antiapoptotic Bcl-2 family proteins (IC50 values are 1.47, 1.21, 2.02, 0.66, 1.06 and 0.79 μM for Bcl-XL, Bcl-2, Bcl-W, Bcl-B, Bfl-1 and Mcl-1 respectively). Reverses gefitinib-resistance in mice bearing tumors with EGFR-T790M mutation. Also blocks Kir2.1 channels (EC50 ≤ 100 nM).
