Methylated 1,2-naphthoquinone derivative SJ006 as an inhibitor of human glucose 6-phosphate dehydrogenase in non-small cell lung cancer cell lines
SJ006, a methylated 1,2-naphthoquinone derivative, has been identified as a potent inhibitor of glucose 6-phosphate dehydrogenase (G6PD) in non-small cell lung cancer (NSCLC) cell lines. The study demonstrates that SJ006 induces significant cytotoxicity and disrupts redox balance, leading to cell cycle arrest and apoptosis. Unlike traditional inhibitors, SJ006 does not affect G6PD expression levels, suggesting a novel mechanism of action. These findings position SJ006 as a promising candidate for further development in cancer therapy, particularly for NSCLC.
