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.

anti-oxidant properties. There are conflicting reports concerning the structural/electronic basis of the anti-oxidant activity of curcumin. Curcumin is a symmetrical diphenolic dienone. A series of enone analogues of curcumin were synthesized that included: (1) curcumin analogues that retained the 7-carbon spacer between the aryl rings; (2) curcumin analogues with a 5-carbon spacer; and (3) curcumin

A selective mono-1,4-hydrocyanation of 10 diarenyl ketones usingpotassiumhexacyanoferrate(II) as an eco-friendlycyanidesource, potassium hydroxide as a catalyst, and benzoyl chloride as a promoter has been achieved. This protocol has the advantages of a non-toxic cyanidesource, a heavy metal-free catalyst, selectivity, very good yields and a simple work-up procedure.

the construction of quaternarycarboncenters is reported. Glucoamylase from Aspergillus niger (AnGA) was used as a sustainable and eco-friendly catalyst. Various highly substituted trans-cyclohexanones with a quaternarycarboncenter were obtained with yields of up to 92%. As a novel case of enzyme promiscuity, this work provides a bio-catalytic alternative for construction of quaternarycarbon centers

herein we report the anti-T. vaginalis evaluation of 21 synthetic monocarbonyl analogues of curcumin, which itself has been reported to possess antiparasitic potential. From the in vitro analysis of the synthetic molecules, untreated trophozoites, and metronidazole at 100 μM, it was observed that three curcumin analogues (3a, 3e, and 5e) exhibited anti-T. vaginalis activity comparable to metronidazole
