Mono-Carbonyl Curcumin Analogs for Cancer Therapy

抄録

Curcumin has long been recognized for its anti-inflammatory properties. An antitumor effect has been recently reported in curcumin and clinical trials are being conducted. However, a large amount of required intake to obtain the antitumor effect of curcumin has been regarded as a problem. Therefore, curcumin analogs have been created by many researchers to enhance the effects of curcumin. We have synthesized >50 curcumin analogs and revealed greater growth suppression of various tumor cells with mono-carbonyl analogs than curcumin. Mechanistically, mono-carbonyl analogs inhibited transcriptional activity (e.g., nuclear factor kappa B, signal transducer, and activator of transcription 3) or activated caspase-3. Additionally, mono-carbonyl analogs of curcumin control tumor cell metabolism. Herein, we summarize the current knowledge about mono-carbonyl curcumin analogs and discuss their potential clinical applications.
