The present work was conducted to investigate the effect of curcumin nanoparticles (CUR NPs) on cisplatin-induced hepatotoxicty and nephrotoxicity in rats. Rats were divided randomly into the following: control, rats treated daily with CUR NPs (50 mg/kg body wt/day) for 14 days, rats treated with a single dose of cisplatin (12 mg/kg body wt, i.p), and rats treated with a single dose of cisplatin followed by a daily administration of CUR NPs for 14 days. Cisplatin-induced hepato- and nephrotoxicity were evaluated by histological examinations and biochemical analyses of liver and kidney functions. Cisplatin induced significant increases in the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) and in the levels of bilirubin, urea, uric acid and creatinine. In addition, the levels of hepatic and renal lipid peroxidation (MDA), nitric oxide (NO), and serum tumor necrosis factor-α (TNF-α) increased significantly. However, cisplatin significantly decreased hepatic and renal reduced glutathione levels and renal Na/K-ATPase activity. Treatment with CUR NPs ameliorated almost all the biochemical changes induced by cisplatin and improved the histopathological alterations in liver and kidney. In conclusion, the present findings indicate that CUR NPs offered an effective protection against cisplatin-induced hepatotoxicity and nephrotoxicity through its antioxidant and anti-inflammatory properties.

The clinical application of curcumin (CUR) is restricted by its low solubility, instability, and poor bioavailability. To overcome these limitations, we developed a novel stearic acid-grafted inulin-based nano-delivery system for CUR encapsulation. The structure of stearoyl inulin (SA-IN) was characterized using Fourier-transform infrared spectroscopy, hydrogen nuclear magnetic resonance, thermogravimetric analysis, and contact angle measurements.

In recent years, the use of cationic peptides as alternative drugs with anticancer activity has received attention. In this study, the targeted release of curcumin (Cur) and CM11 peptide alone and together against hepatocellular carcinoma (HCC) was evaluated using chitosan nanoparticles (CS NPs) coated with Pres1 that target the SB3 antigen of HCC cells (PreS1-Cur-CM11-CS NPs). SB3 protein is the specific antigen of HCC and the PreS1 peptide is a part of the hepatitis B antigen, which can specifically bind to the SB3 protein.

Oral cavity cancer poses a significant health threat due to its aggressive nature and limited responsiveness to traditional therapies like chemotherapy and radiation, highlighting the need for more effective treatment options. To address this, researchers have explored a novel approach using niosome nanoparticles to co-encapsulate curcumin (CUR) and cisplatin (Cis), to enhance therapeutic efficacy. While CUR has anti-cancer properties, its poor bioavailability limits its effectiveness.

Article Synopsis
- Recent advancements in orally-targeted nanostrategies using multiple nutraceuticals show promise for ulcerative colitis therapy, improving patient compliance and effectiveness despite challenges like poor solubility and gastrointestinal retention.
- The study introduces nanoparticles crafted from quaternary ammonium chitosan and succinic acid-modified γ-cyclodextrin, with egg white-derived peptides enhancing the delivery and bioavailability of hydrophobic curcumin.
- Findings indicate that these nanoparticles significantly increase cellular absorption and oral bioavailability, support colonic microenvironment interactions, and promote intestinal health through improved amino acid metabolism.

A stimuli-responsive drug delivery system is developed for controlled delivery of curcumin (Cur) and chemo-photothermal therapy of breast cancer (BC). Cur is first loaded into mesoporous polydopamine nanoparticles (mPDA NPs) by π-π stacking, and then the Cur loaded mPDA NPs (mPDA NPs@Cur) are encapsulated in the hydrogels prepared through the crosslinking of oxidized konjac glucomannan (oxKGM) and carboxymethyl chitosan (CMCS). Owing to the pH-sensitivity of the hydrogels and the outstanding photothermal conversion capability of mPDA NPs, the release of Cur from the hydrogels can be greatly accelerated in acidic media upon near infrared (NIR) irradiation.
