  • Biological description

    Cell-permeable cross-conjugated α,β-unsaturated dienone compound reported to induce caspase activation and apoptosis (IC50 = 1.76 and 1.6 µM in E1A and E1A/C9DN cells respectively) via an apoptosome-independent mitochondrial pathway by selectively inhibiting ubiquitin isopeptidase activity. The cellular expression of Bax and Bak is essential for G5-activated apoptosis, while Bcl-2 appears to protect cells against the effect of G5.
