PURPOSE: The optimal health benefits of curcumin are limited by its low solubility in water and corresponding poor intestinal absorption. Cyclodextrins (CD) can form inclusion complexes on a molecular basis with lipophilic compounds, thereby improving aqueous solubility, dispersibility, and absorption. In this study, we investigated the bioavailability of a new γ-cyclodextrin curcumin formulation (CW8). This formulation was compared to a standardized unformulated curcumin extract (StdC) and two commercially available formulations with purported increased bioavailability: a curcumin phytosome formulation (CSL) and a formulation of curcumin with essential oils of turmeric extracted from the rhizome (CEO)...

Curcuminoids are turmeric-extracted phytochemicals with documented chemopreventive and anti-tumor activities against several types of malignancies. Curcuminoids can modulate several molecular pathways and cellular targets involved in different stages of tumor initiation, growth and metastasis. Bisdemethoxycurcumin (BDMC) is a minor constituent (approximately 3%) of curcuminoids that has been shown to be more stable than the other two main curcuminoids i.e. curcumin and demthoxycurcumin. Recent studies have revealed that BDMC has anti-tumor effects exerted through a multimechanistic mode of action involving inhibition of cell proliferation, invasion and migration, metastasis and tumour growth, and induction of apoptotic death in cancer cells...

Curcumin is a constituent (up to ∼5%) of the traditional medicine known as turmeric. Interest in the therapeutic use of turmeric and the relative ease of isolation of curcuminoids has led to their extensive investigation. Curcumin has recently been classified as both a PAINS (pan-assay interference compounds) and an IMPS (invalid metabolic panaceas) candidate. The likely false activity of curcumin in vitro and in vivo has resulted in >120 clinical trials of curcuminoids against several diseases. No double-blinded, placebo controlled clinical trial of curcumin has been successful...

Despite the increasing attention on the therapeutic potential of Curcuma longa (turmeric), the biological activities of curcuminoids other than curcumin are not well understood. Here, we investigated antivasoconstrictive activities of C. longa extract and its ingredients using freshly isolated rat aortic rings. C. longa extract significantly suppressed agonist-stimulated vasoconstriction, and cyclocurcumin was found to be the most potent (IC50 against phenylephrine-induced vasoconstriction: 14.9 ± 1.0 μM) among the 10 tested ingredients including four curcuminoids...
