The characterisation, inclusion complexation behaviours, and binding ability of inclusion complexes of luteolin (LU) with four polyamine-modified β-cyclodextrins (NH2-βCD, EN-βCD, DETA-βCD, TETA-βCD; where EN = ethylenediamine; DETA = diethylenediamine; TETA = triethylenetetramine) were investigated in both the solid and solution forms by photoluminescence spectroscopy, 1H and 2D NMR spectroscopy, differential scanning calorimetry, X-ray diffraction, and scanning electron microscopy. The results showed that the water solubility, and the anti-oxidant activity and anti-cancer activity of LU were significantly increased in the inclusion complex with polyamine-β-cyclodextrin. The LU/CDs complex will be useful for its application as herbal medicine or healthcare product.

Background: Curcumin is a natural polyphenolic compound with anti-cancer, antiinflammatory, and anti-oxidation properties. Low water solubility and rapid hydrolytic degradation are two challenges limiting use of curcumin. </P><P> Objective: In this study, the roles of the native/modified forms of Bovine Serum Albumin (BSA), &#946;-lactoglobulin (&#946;-lg) and casein, as food-grade biopolymers and also protein chemical modification, in stabilizing and on biological activity of curcumin were surveyed. </P><P> Methods: In this article, we used various spectroscopic as well as cell culture-based techniques along with calculation of thermodynamic parameters. </P><P> Results: Investigation of curcumin stability indicated that curcumin binding to the native BSA and modified &#946; -lg were stronger than those of the modified BSA and native &#946; -lg, respectively and hence, the native BSA and modified &#946;-lg could suppress water-mediated and light-mediated curcumin degradation, significantly. Moreover, in the presence of the native proteins (BSA and casein), curcumin revealed elevated in vitro anti-cancer activity against MCF-7 (human breast carcinoma cell line) and SKNMC (human neuroblastoma cell line). As well, curcumin, in the presence of the unmodified “BSA and &#946;-lg”, was more potent to decrease ROS generation by hydrogen peroxide (H2O2) whereas it led to an inverse outcome in the presence of native casein. Overall, in the presence of the protein-bound curcumin, increased anti-cancer activity and decreased ROS generation by H2O2 in vitro were documented. </P><P> Conclusion: It appears that “water exclusion” is major determinant factor for increased stability/ efficacy of the bound curcumin so that some protein-curcumin systems may provide novel tools to increase both food quality and the bioavailability of curcumin as health promoting agent.

Nowadays, cancer treatment has been a big challenge to healthcare systems. Most of clinical anti-cancer therapies are toxic and cause adverse effects to human body. Therefore, current trend in science is seeking and screening of natural compounds which possess antineoplastic activities to utilize in treatment. Uvaria L. - Annonaceae includes approximately 175 species spreading over tropical areas of Asia, Australia, Africa and America. Studies on chemical compositions and pharmacological effects of Uvaria showed that several compound classes in this genus such as alkaloid, flavonoid, cyclohexen derivaties, acetogenin, steroid, terpenoid, etc. indicate considerable biological activities, for example anti-tumor, anti-cancer, antibacterial, antifungal, antioxidant, etc. Specifically, anti-cancer activity of fractions of extract and pure isolated compounds stands out for cytotoxicity against many cancer cell lines. This study provides an overview of anti-cancer activity of Uvaria and suggests a potential for further studies on seeking and developing novel anti-cancer compounds. Key words: Anti-cancer, Uvaria.

Ezetimibe, the antihyperlipidemic drug of poor bioavailability was complexed with native and derivatized cyclodextrins.The complexes were characterized in terms stability, stoichiometry and structure using various 1D and 2D solution NMR spectroscopic techniques. The complexes were found to be of moderate stability (logK[3). The least stable inclusion complex is formed with b-cyclodextrin, while the ezetimibe-methylated-b--cyclodextrin has a 7-fold higher stability. The results can be useful to improve the poor water-solubility and the concomitant bioavailability of ezetimibe.
