Curcumin, the phytochemical component in turmeric, is used as a dietary spice and a topical ointment for the treatment of inflammation in India for centuries. Curcumin (diferuloylmethane) is relatively insoluble in water, but dissolves in acetone, dimethylsulphoxide, and ethanol. Commercial grade curcumin contains 10-20% curcuminoids, desmethoxycurcumin, and bisdesmethoxycurcumin and they are a...

Recently, many studies on health benefits associated with curcumin have been reported. In this study, the effects of curcumin on apoptosis of papillary thyroid cancer cell line K1 and its potential mechanisms were investigated. Curcumin was found to significantly inhibit cell viability and promoted cell apoptosis in a dose-dependent manner. Moreover, curcumin-induced cell apoptosis was characte...

Curcumin has been reported to possess multifunctional bioactivities with low toxicity. However, the clinical application of curcumin has been significantly limited by its instability and poor metabolic property. Up to now, multiple approaches are being sought to overcome these limitations to obtaining “super curcumin”, and many analogues of curcumin have been designed and synthesized. In all of...

Curcumin exhibits anti-inflammatory and antitumor activities. Although its functional mechanism has not been elucidated so far, numerous studies have shown that curcumin induces apoptosis in cancer cells. In the present study, we show that subtoxic concentrations of curcumin sensitize human renal cancer cells to the tumor necrosis factor-related apoptosis inducing ligand (TRAIL)-mediated apopto...

introduction: considering the importance of prevention in periodontal diseases and the important role of aggregatibacter actinomycetemcomitans in induction and progression of these diseases, the aim of the present in vitro study was to compare the antimicrobial effects of chlorhexidine digluconate (chx), curcumin and light-emitting diode (led) laser, on this bacterium. methods: antimicrobial ac...

The cytotoxic activity of curcumin towards CCRF-CEM human T-cell leukemia cells was measured by the MTT assay. Tumor cells were more sensitive to the cytotoxic activity of curcumin or curcumin-Cu (II)compared to normal cells, and the IC(50) of curcumin towards CCRF-CEM cells was 8.68 microM, and that of curcumin-Cu (II) was 8.14 microM. The cell cycle distribution of curcumin-treated CCRF-CEM c...

The aim of this work is to develop a curcumin nanoemulsion for transdermal delivery. The incorporation of curcumin inside a nanoglobul should improve curcumin stability and permeability. A nanoemulsion was prepared by the self-nanoemulsification method, using an oil phase of glyceryl monooleate, Cremophor RH40 and polyethylene glycol 400. Evaluation of the nanoemulsion included analysis of part...

Melanoma is known as the most common malignant cutaneous cancer. Curcumin, a natural component, has been shown to have various activities such as anti-oxidant, anti-septic, anti-inflammatory, anti-biotic, anti-amyloid and anti-thrombosis. However, there is a greatest obstacle in the administration of curcumin due to its hydrophobicity and low oral bioavailability. In this study, we formulated c...

The aim of present work was to enhance the aqueous solubility and dissolution rate of the curcumin, a water insoluble yellow colored phenolic pigment with good anti-inflammatory property obtained from dried rhizomes of plant Cucrcuma longa. This paper presents physicochemical evaluations of curcumin and its molecular inclusion complexes with α-cyclodextrin. Phase solubility studies revealed lin...

PURPOSE Curcumin is a nontoxic, chemopreventive agent possessing multifaceted functions. Our previous study showed that curcumin inhibits androgen receptor (AR) through modulation of Wnt/β-catenin signaling in LNCaP cells. Therefore, we investigated the in vivo effects of curcumin by using LNCaP xenografts. MATERIALS AND METHODS LNCaP cells were subcutaneously inoculated in Balb/c nude mice. ...
