How to use

In Vitro:

Apoptosis Activator 2 promotes the cytochrome c-dependent oligomerization of Apaf-1 into the mature apoptosome. Apoptosis Activator 2 exerted a cytostatic effect on the majority of cell lines tested, inhibiting cell growth by 50–100% at 10 μM in 40 of 48 cell lines tested. Apoptosis Activator 2 exerted a cytotoxic effect, reducing the cell numbers by 10–50% and 50–100% in four and eight cell lines, respectively, from the initial levels when tested at 10 μM. At 100 μM Apoptosis Activator 2 exhibited 100% cytotoxicity in virtually all cell lines, an effect that may be due to nonspecific toxicity. Of the cancer cell lines tested in the panel, cell lines of lymphoid origin (CCRF-CEM, MOLT-4, and Jurkat) were quite sensitive to compound 2-induced killing, with IC50 values ranging from 4 to 9 μM. Apoptosis Activator 2 is a potent and selective carboxylesterase inhibitor with Ki of 67/31/65 nM for hiCE/hCE/rCE respectively, also has less inhibition on AChE/BChE with Ki of 48.2/12.6 uM .
