Nrf2 HO-1 activator 2 (compound 13m), a difluoro-substituted derivative, is a highly potent activator of Nrf2 HO-1. It exhibits substantial neuroprotective and antioxidant properties by activating the Nrf2 HO-1 pathway through phosphorylation of ERK1 2, JNK, or Akt in PC12 cells. This compound finds utility in the investigation of Parkinson's disease (PD) [1].
Nrf2 activator-2 (referred to as compound O15), an Osthole derivative, is a highly potent Nrf2 agonist exhibiting an EC 50 of 2.9 μM in 293 T cells. By effectively disrupting the binding between Keap1 and Nrf2, Nrf2 activator-2 activates the Nrf2 pathway. Furthermore, this compound significantly reduces the ubiquitination of Nrf2 in cells, indicating its potential in regulating Nrf2 activity [1].

Shinorine, a mycosporine-like amino acid (MAA), is a small molecule sunscreen produced in some bacteria. Shinorine ameliorates chromium induced toxicity in zebrafish hepatocytes through the facultative activation of Nrf2-Keap1-AREpathway. Shinorine is also an analogue of porphyra-344. Both porphyra-334 and shinorine are antioxidants and direct antagonists of Keap1-Nrf2 binding. Shinorine may be a useful agent to prevent or retard the progression of multiple degenerative disorders of ageing. Shinorine is a demethyl-analog of Porphyra 334.
