1,4‑Naphthoquinone derivatives have superior anticancer effects, but their use has been severely limited in clinical practice due to adverse side effects. To reduce the side effects and extend the anticancer effects of 1,4‑naphthoquinone derivatives, 2‑(butane‑1‑sulfinyl)‑1,4‑naphthoquinone (BQ) and
Cytotoxicity and mode of action of a naturally occurring naphthoquinone, 2-acetyl-7-methoxynaphtho[2,3-b]furan-4,9-quinone towards multi-factorial drug-resistant cancer cells.

OBJECTIVE
• To evaluate the cytotoxicity of dimeric naphthoquinones (BiQs) in prostate cancer cells. • To assess the interaction of dimeric naphthoquinones with common therapies including radiation and docetaxel.
METHODS
• The cytotoxicity of 12 different dimeric naphthoquinones was assessed in
2-Methoxy-6-acetyl-7-methyljuglone (MAM), a natural naphthoquinone, induces NO-dependent apoptosis and necroptosis by H2O2-dependent JNK activation in cancer cells.

Redox signaling plays a fundamental role in maintaining cell physiological activities. A deregulation of this balance through oxidative stress or nitrosative stress has been implicated in cancer. Here, we reported that 2-methoxy-6-acetyl-7-methyl juglone (MAM), a natural naphthoquinone isolated from
