Application

Brusatol has been used to study the protective role of Nrf2 (nuclear factor, erythroid 2 like 2 ) in intestinal ischemia/reperfusion induced injury.

Biochem/physiol Actions

Brusatol (Brutasol) is a plant-derived natural quassinoid that exhibits broad cytotoxicity in cancer cultures (IC50 <1 μM against 457 cancer cell lines) by inhibiting de novo synthesis of cellular proteins (Effective conc. <50 nM in A549 cells), including NRF2.
Brusatol promotes Nrf2 (nuclear factor, erythroid 2 like 2 ) ubiquitination and degradation. Brusatol upregulates the expression of multiple ribosomal components and controls macromolecular complex function.

The mechanism by which brusatol inhibits protein synthesis in rabbit reticulocytes has been investigated. When added to reticulocyte lysates, brusatol inhibits endogenous protein synthesis only after a lag of 2-4 min at 30 degrees C. During this period 80 S

The KEAP1/Nrf2 pathway senses and responds to changes in intracellular oxidative stress. Mutations that result in constitutive activation of Nrf2 are present in several human tumors, especially non-small cell lung cancer. Therefore, compounds that inhibit Nrf2 activity might be beneficial
