Alternative Name: CBFβ-Runx1 inhibitor II

Chemical Name: 7-Chloro-1,3-dihydro-5-(1H-pyrrol-2-yl)-2H-1,4-benzodiazepin-2-one

Biological Activity

Core binding factor (CBF) inhibitor; preferentially kills human leukemia cell lines with CBF fusion proteins (IC50 = 1.1 μM). Represses RUNX1/CBFβ-dependent transactivation in reporter assays and inhibits transcriptional regulation by RUNX1 and CBFβ. Reduces leukemia burden in a mouse model. Attenuates RUNX1-dependent hematopoiesis in zebrafish embryos. Also a Tat antagonist; inhibits HIV-1 replication in vitro.

Technical Data

Soluble to 100 mM in DMSO
>98 %
Store at +4°C
