| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Pterisolic Acid B is a Nrf2 Activator by Targeting C171 within Keap1-BTB Domain.[Pubmed:26757824]
Sci Rep. 2016 Jan 13;6:19231.
The use of chemoprotective agents to minimize the side effects of the chemotherapy, primarily via activation of the Nrf2 pathway, is an emerging research field, which has attracted broad attention from both academia and pharmaceutical industry. Through high-throughput chemical screens we have disclosed that Pterisolic acid B (J19), a naturally occuring diterpenoid, is an effective Nrf2 activator. We have also identified a more potent natural product analogue J19-1 by semisynthesis and the subsequent biochemical evaluations revealed that J19-1 activates the Nrf2 pathway by covalently modifying Cys171 of keap1, which inhibits Nrf2 degradation mediated by Keap1-Cul3 complexes. Ultimately, we have demonstrated that J19-1 shows significant cytoprotective effect against cisplatin-induced cytotoxicity in HKC cells.
