6H-Indeno[1,2-e]tetrazolo[1,5-b][1,2,4]triazin-6-one & 10H-Indeno[2,1-e]tetrazolo[1,5-b][1,2,4]triazin-10-one Yellow solid. PROTECT FROM LIGHT. PACKAGED UNDER INERT GAS. A cell-permeable compound that selectively induces apoptosis in AML (Acute Myelogenous Leukemia) with little effect on normal CD34+ AML progenitor cells. Shown to directly inhibit both PDK1 and Akt activities in in vitro kinase assays in a dose-dependent manner and block cellular phosphorylation of Akt at both Ser473 and Thr308. The dual inhibition nature against both PDK1/Akt and Flt3/PIM signaling pathways allows effective killing of AML cells (Average IC50 = 1.05, 1.91, and 0.43 µM for AML with wild-type Flt3, single mutant ITD/D835, and double mutant Flt3-ITD-TDK, respectively) that are otherwise resistant to inhibitors that target only the PDK1/Akt pathway. Purity: ≥98% by HPLC (sum of two isomers). Ref.: Zeng, Z., et al. 2006. Cancer Res. 66, 3737. Koul, D., et al. 2006. Mol. Cancer Ther. 5, 637. Mandal. M., et al. 2006. Oral Oncol. 42, 430. Mandal.
