IC50: 0.52 μM in Bax assay

Bax channel blocker is an inhibitor of Bax-mediated mitochondrial cytochrome c release.

In the cytosol, cytochrome c is found to form a complex with dATP, Apaf-1, and procaspase-9, which results in caspase 9 activation followed by downstream activation of other caspases, such as caspase 8, ultimately leading to the cell death. After caspase 8 cleavage, the 15.5 kDa C-terminal fragment of Bid interacts with Bak and Bax.

In vitro: Bax channel blocker, a 3,6-dibromocarbazole derivative, was observed to inhibit cytochrome c releasing from mitochondria by Bax channel modulation. The monohydroxy analogue Bax channel blocker remained the unprecedented inhibition of Bax-induced cytochrome c release at 10 μM. The IC50 value of Bax channel blocker was determined to be 0.52 μM, indicating that Bax channel blocker was a Bax channel inhibitor as hypothesized. Moreover, in the liposome assay, Bax channel blocker showing significant inhibition (>65%) of cytochrome c release at 10 μM also demonstrated sub-micromolar IC50 value [1].

In vivo: So far, there is no animal in vivo study conducted for Bax channel blocker.
