生物&药学活性

Covalent BAX inhibitor 1 (CBI1) is a specific, covalent BAX inhibitor selectively derivatizes BAX at Cys126 and inhibits BAX activation by triggering ligands or point mutagenesis.
CBI1 is not an activator of BAX.
CBI1 demonstrates potent dose-responsive blockade of BAX-mediated liposomal poration upon triggering by the physiologic tBID ligand in liposomal release assay.
CBI1 acts at an upstream control point, specifically the conformational activation step of ligand-triggered monomeric BAX.
CBI1 blocks t-2-hex lipidation and oligomerization of BAX, inhibits BAX activation induced by BH3 ligands, F116A mutagenesis or t-2-hex.
CBI1 not only competes for C126 derivatization to block t-2-hex-mediated BAX sensitization but also independently restrains BAX by stabilizing key structures of its monomeric architecture.
