  diarylpentanoid curcumin analogues 5, 6, 7, and 13 demonstrated higher inhibition of microsomal prostaglandin E synthase‐1 activity with IC50 ranging from 2.41 to 4.48 μm, which was less than that of curcumin. The present results suggest that some of these diarylpentanoid analogues were able to inhibit the activity of these enzymes. This raises the possibility that diarylpentanoid analogues of curcumin might

  In the present study, a series of forty-five asymmetrical meta-methoxylated diarylpentanoids have been synthesized, characterized and evaluated for their in-vitro anti-cancer potential. Among the forty-five analogs, three compounds (20, 33 and 42) have been identified as lead compounds due to their excellent inhibition against five human cancer cell lines including SW620, A549, EJ28, HT1080 and MCF-7. Structure-activity relationship study on cytotoxicity of tested compounds suggested that the presence of meta-oxygenated phenyl ring played a critical role in enhancing their cytotoxic effects. Compounds 33 and 42 in particular, exhibited strongest cytotoxicity against tested cell lines with the IC50 values ranging from 1.1 to 4.3 M. Subsequent colony formation assay on SW620 cell line showed that both compounds 33 and 42 possessed strong anti-proliferative activity. In addition, flow cytometry based experiments revealed that these compounds could trigger intracellular ROS production thus inducing G2/M-phase cell arrest and apoptosis. All these results suggested that poly meta-oxygenated diarylpentnoid is a promising scaffold which deserved further modification and investigation in the development of natural product based anti-cancer drug.

  Curcumin has a surprisingly wide range of chemo-preventive and chemo-therapeutic activities and is under investigation for the treatment of various human cancers. However, the clinical application of curcumin has been significantly limited by its instability and poor metabolic property. Although a number of synthetic modi. cations of curcumin have been studied intensively in order to develop a molecule with enhanced bioactivities, few synthetic studies were done for the improvement of pharmacokinetic profiles. In the present study, a series of mono-carbonyl analogues of curcumin were designed and synthesized by deleting the reactive beta-diketone moiety, which was considered to be responsible for the pharmacokinetic limitation of curcumin. The results of the in vitro stability studies and in vivo pharmacokinetic studies indicated that the stability of these mono-carbonyl analogues was greatly enhanced in vitro and their pharmacokinetic profiles were also significantly improved in vivo. Furthermore, the cytotoxic activities of mono-carbonyl analogues were evaluated in seven different tumor cell lines by MTT assay and the structure-activity relation (SAR) was discussed and concluded. The results suggest that the five-carbon linker-containing analogues of curcumin may be favorable for the curcumin-based drug development both pharmacokinetically and pharmacologically.
