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-ARE pathway. 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. |
