Abstract:
We report a case of successful design of glutathione S-transferase (GST) inhibitors via a natural product-inspired and electrophilicity-based strategy. Based on this strategy, a novel piperlongumine analog (PL-13) bearing a para-trifluoromethyl group and an α-chlorine on its aromatic and lactam rings, respectively, surfaced as a promising GST inhibitor, thereby overcoming cisplatin resistance in lung cancer A549 cells.
