A series of novel analogues of 1,5-bis(4-hydroxy-3-methoxyphenyl)-penta-(1E,4E)-1,4-dien-3-one (C-5-curcumin), which is a natural analogue of curcumin isolated from the rhizomes of Curcuma domestica Val. (Zingiberacea), were synthesized and evaluated for their cytotoxicities against human colon cancer cell line HCT-116 to conclude the SAR of C-5-curcuminoids for further development of their use in cancer chemotherapy: (1) Bis(arylmethylidene) acetone serves as a promising skeleton for eliciting cytotoxicity. (2) The 3-oxo-1,4-pentadiene structure is essential for eliciting cytotoxicity. (3) As for the extent of the aromatic substituents, hexasubstituted compounds exhibit strong activities, in which 3,4,5-hexasubstitution results in the highest potency. (5) The symmetry between two aryl rings is not an essential requirement for bis(arylmethylidene) acetones to elicit cytotoxicity. (6) para-Positions allows the installation of additional functional groups for use as molecular probes. By taking advantage of the SAR diagram, we have elaborated several advanced derivatives having GI(50) of single-digit micromolar potencies that will function as molecular probes to target and/or report key biomolecules interacting with curcumin and C-5-curcumin.

It has been demanded to improve the poor solubility of curcumin to develop an anti-tumor compound capable of inhibiting the growth of various cancer cells at a low concentration. Thus, disclosed is a novel synthetic compound, a bis(arylmethylidene)acetone, which has both of an excellent anti-tumor activity and a chemo-preventive activity. A bis(arylmethylidene)acetone (i.e., a derivative having a curcumin skeleton) which is an anti-tumor compound and has a chemo-preventive activity is synthesized and screened. A derivative having enhanced anti-tumor activity and chemo-preventive activity can be synthesized.
