This invention relates generally to methods of treating aggressive cancers, such as hormone-refractory metastatic prostate cancer, by exposing the aggressive cancer cells to curcumin analogs having the claimed structural scaffolds and side groups. The anticancer effects of curcumin are associated with its influence on numerous growth factors within the cells. However, its clinical development has been limited by its suboptimal pharmacokinetics and poor bioavailability caused by poor solubility in water and rapid in vivo metabolism. There is the need to develop new and improved curcumin analogs with better potency, water solubility, and in vivo metabolic stability, as well as retained safety profiles. Curcumin analogs having one of the claimed four novel scaffolds with basic heteroaromatic side groups show the ability to decrease aggressive cancer cell viability and to inhibit aggressive cancer cell growth.

To improve the potential of curcumin to treat advanced hormone-refractory prostate cancer, three series (A-C) of heteroaromatic analogs (thirty two compounds) with different monoketone linkers have been synthesized and evaluated for cytotoxicity against two human androgen-independent prostate cancer cell lines (PC-3 and DU-145). Among them, thirty analogs are more potent than curcumin against PC-3 cells, and twenty one analogs are more cytotoxic towards DU-145 cells relative to curcumin. The most potent compounds (44, 45, 51, and 52) also showed impressive cytotoxicity against three other metastatic cancer cell lines (MDA-MB-231, HeLa, and A549), with IC50 values ranging from 50 nM to 390 nM. All four most potent analogs exhibited no apparent cytotoxicity towards the MCF-10A normal mammary epithelial cells. Taken together, selective enhancement of cell death in prostate cancer cell lines and other aggressive cancer cell lines suggests that nitrogen-containing heteroaromatic rings are promising bio-isosteres of the substituted phenyl ring in curcumin.
