The objective of this study was to compare the pharmacokinetics and metabolism of polymeric nanoparticle-encapsulated (nanocurcumin) and solvent-solubilized curcumin formulations in Sprague-Dawley (SD) rats. Nanocurcumin is currently under development for cancer therapy. Since free, unencapsulated curcumin is rapidly metabolized and excreted in rats, upon intravenous (i.v.) administration of na...

background: curcumin has shown to affect sperm motility and function in vitro and fertility in vivo. the molecular mechanism(s) by which curcumin affects sperm motility has not been delineated. since modulation of intracellular ph (phi) and plasma membrane polarization is involved in sperm motility, the present study was conducted to investigate the effect of curcumin on these sperm (human and ...

To enhance the curcumin absorption by oral administration, liposome-encapsulated curcumin (LEC) was prepared from commercially available lecithins (SLP-WHITE and SLP-PC70) and examined for its interfacial and biochemical properties. A LEC prepared from 5 wt % of SLP-PC70 and 2.5 wt % of curcumin gave a good dispersibility with 68.0% encapsulation efficiency for curcumin, while those from SLP-WH...

Malignant melanoma is a melanocytic tumor with a high potential of invasion and metastasis. Curcumin is extracted from Curcuma longa L.; curcumin has anti-tumor efficacy in multiple systemic malignancies. Here, we investigated the effect of curcumin on A375 human melanoma cells. A375 cells were cultivated, passaged, and treated with different concentrations of curcumin. We observed the cellular...

the reaction of bis[4-hydroxy-3-methoxyphenyl]-1,6-heptadiene-3,5-dione (curcumin) and two novel ligands of bis[4-tetrabenzylglucose-3-methoxyphenyl]-1,6-heptadiene-3,5-dione (bis(tetrabenzylglucose)curcumin) (btbgc) and bis[4-tetraacetylglucose-3-methoxyphenyl]-1,6-heptadiene-3,5-dione (bis(tetraacetylglucose)curcumin) (btagc) with vanadium in methanol, in a 2:1 molar ratio, which yield the co...

background: curcumin as a yellow natural compound extracted from turmeric root is known it as an antibacterial agent. one of the nanoparticles ability is to decrease the defects of usual drug delivery systems. chitosan is a low toxic, biodegradable, biocompatible and safe polymer which is used in production of nanoparticles. nanoparticles like chitosan-tripolyphosphate (tpp) are able to increas...

Curcumin, the yellow pigment of turmeric found in Southeast Indian food, is one of the most popular phytochemicals for cancer prevention. Numerous reports have demonstrated modulation of multiple cellular signaling pathways by curcumin and its molecular targets in various cancer cell lines. To identify a new molecular target of curcumin, we used shape screening and reverse docking to screen the...

Curcumin has shown considerable pharmacological activity, including anti-inflammatory, but its poor bioavailability and rapid metabolization have limited its application. The purpose of the present study was to formulate curcumin-solid lipid nanoparticles (curcumin-SLNs) to improve its therapeutic efficacy in an ovalbumin (OVA)-induced allergic rat model of asthma. A solvent injection method wa...

OF THESIS SYNTHESIS AND CHARACTERIZATON OF CURCUMIN POLYMER FOR APPLICATION IN RADIATION INDUCED LUNG DAMAGE Radiotherapy is used as a primary treatment for many cancers, including lung cancer. Although radiotherapy has proven to be an effective cancer treatment, its use is heavily limited due to the peripheral toxicity to healthy tissue. In this work, the antioxidant, curcumin, was tested as a...

A cationic liposome-PEG-PEI complex (LPPC) was used as a carrier for the encapsulation of hydrophobic curcumin to give curcumin/LPPC. Curcumin/LPPC had an average size less than 270 nm and a zeta potential of approximately 40 mV. The LPPC encapsulation efficiency for curcumin was about 45%. The authors found it surprising that the cytotoxic activity of the curcumin/LPPC was fivefold higher than...
