Improved anti-tumor activity of oxaliplatin by encapsulating in anti-DR5 targeted gold nanoparticles.

Oxaliplatin is one of the chemotherapeutic agents in the first line therapy for treatment of colorectal cancer. But, limitations of chemotherapy affects the clinical applicability of oxaliplatin depriving its activity at targeted site attributed to the lack of site specificity. This limitation paves the way for undesirable toxic effects to healthy cells resulting in sub-standard drug amount at the tumors obliging for increased dose.

Oxaliplatin immunohybrid nanoparticles in vitro synergistic suppression evaluation in treatment of colorectal cancer.

In the present study, we have investigated the enhanced synergistic and apoptotic activity of immunohybrid nanoparticles encapsulating oxaliplatin and covalently conjugated with TRAIL (Apo-2L/CD-253). Time-dependent cytotoxicity activity of nanoparticles was determined by MTT assay in HT-29 cells. Nuclear morphological changes and assessment of apoptotic ratio was analyzed by DAPI (4'6-diamidino-2-phenylindole) staining and annexin-propidium iodide (PI) assay.

Formulation and optimization of oxaliplatin immuno-nanoparticles using Box-Behnken design and cytotoxicity assessment for synergistic and receptor-mediated targeting in the treatment of colorectal cancer.

Conventional chemotherapy majorly lacks clinical application attributed to its inspecificity, adverse effects and inability to penetrate into tumor cells. Hence, the aim of the study was to prepare oxaliplatin solid lipid nanoparticles (OP-SLN) by microemulsion method optimizing it by Box-Behnken design and then covalently conjugated to TRAIL (CD-253) monoclonal antibody (TR-OP-SLN) for targeting colorectal cancer cells. The optimized OP-SLN3 has shown an appreciable particle size (121 ± 1.

5-Fluorouracil enteric-coated nanoparticles for improved apoptotic activity and therapeutic index in treating colorectal cancer.

5-Fluorouracil (5-FU) is one among the anti-cancer agents in FOLFORINOX treatment along with oxaliplatin and irinotecan for the treatment of colorectal cancer. Despite its potential activity on the tumor cells, it lacks site specificity partly attributed by its biodistribution to healthy cells resulting in toxic effects to healthy cells. Therefore, we have formulated 5-fluorouracil enteric-coated nanoparticles (5-FUEC) to localize the drug in the colon area that enables its prolonged presence in target area in a sustained manner.

Lipid-based nanocarriers for breast cancer treatment - comprehensive review.

Breast cancer is the second leading cancer-related disease as the most common non-cutaneous malignancy among women. Curative options for breast cancer are limited, therapeutically substantial and associated with toxicities. Emerging nanotechnologies exhibited the possibility to treat or target breast cancer.

Oxaliplatin immuno hybrid nanoparticles for active targeting: an approach for enhanced apoptotic activity and drug delivery to colorectal tumors.

Tumor necrosis factor related apoptosis inducing ligand (TRAIL) proved to be a promising new target for colorectal cancer treatment. Elevated expression of TRAIL protein in tumor cells distinguishes it from healthy cells, thereby delivering the drug at the specific site. Here, we formulated oxaliplatin immunohybrid nanoparticles (OIHNPs) to deliver oxaliplatin and anti-TRAIL for colorectal cancer treatment in xenograft tumor models.

Formulation and characterization of 5-Fluorouracil enteric coated nanoparticles for sustained and localized release in treating colorectal cancer.

5-Fluorouracil is used in the treatment of colorectal cancer along with oxaliplatin as first line treatment, but it is having lack of site specificity and poor therapeutic effect. Also toxic effects to healthy cells and unavailability of major proportion of drug at the colon region remain as limitations. Toxic effects prevention and drug localization at colon area was achieved by preparing enteric-coated chitosan polymeric nanoparticles as it can be delivered directly to large bowel.

5-Aminosalicylic acid attenuates allergen-induced airway inflammation and oxidative stress in asthma.

Pro-inflammatory cytokines regulate the magnitude of allergic reactions during asthma. Tumor necrosis factor--alpha (TNF-α), interleukin-6 (IL-6) and interleukin-13 (IL-13) play a crucial role in aggravating the inflammatory conditions during allergic asthma. In addition, oxidative stress contributes to the pathogenesis of asthma by altering the physiological condition resulting in the development of status asthmaticus.
