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...

Objectives: Cardiotoxicity is considered the primary cause of death in aluminum phosphide (ALP)-poisoned cases. Curcumin, the active ingredient of turmeric, is a potent protective polyphenol compound against cardiac diseases including cardiotoxicity. This study aimed to examine the probable cardioprotection potential of nanocurcumin in a rat model of ALP-induced cardiotoxicity. Methods: T...

The present study is in continuation of our previous efforts to investigate the preventive efficacy of encapsulated curcumin nanoparticles (nanocurcumin) in mitigating effects of arsenic and/or fluoride. Curcumin was encapsulated in chitosan nanoparticles having a size distribution in the range of 50 nm. Sodium arsenite (2 mg/kg, orally) and Fluoride (50 ppm in drinking water) either alone or i...

Hypoxia induced oxidative stress incurs pathophysiological changes in hypertrophied cardiomyocytes by promoting translocation of p53 to mitochondria. Here, we investigate the cardio-protective efficacy of nanocurcumin in protecting primary human ventricular cardiomyocytes (HVCM) from hypoxia induced damages. Hypoxia induced hypertrophy was confirmed by FITC-phenylalanine uptake assay, atrial na...

Curcumin, the active principle present in the yellow spice turmeric, has been shown to exhibit various pharmacological actions such as antioxidant, anti-inflammatory, antimicrobial, and anti-carcinogenic activities. Previously we have reported that dietary curcumin delays diabetes-induced cataract in rats. However, low peroral bioavailability is a major limiting factor for the success of clinic...

BACKGROUND Curcumin, a yellow polyphenol extracted from the rhizome of turmeric (Curcuma longa), has potent anti-cancer properties as demonstrated in a plethora of human cancer cell line and animal carcinogenesis models. Nevertheless, widespread clinical application of this relatively efficacious agent in cancer and other diseases has been limited due to poor aqueous solubility, and consequentl...

This study investigates the therapeutic effect of a nanocurcumin formulation (NCF) containing nanocurcumin (NC) and pyrroloquinoline quinone (PQQ) on ameliorating hypoxia-induced stress in hypertrophied primary human ventricular cardiomyocytes (HVCM) under hypoxic conditions, as validated in a Sprague-Dawley rat model of chronic hypobaric hypoxia (cHH)-induced right ventricular hypertrophy (RVH...
