Body distributioin of RGD-mediated liposome in brain-targeting drug delivery.

A dual-targeting liposome conjugated with transferrin and arginine-glycine-aspartic acid peptide for glioma-targeting therapy

The treatment of a brain glioma remains one of the most difficult challenges in oncology. In the present study a delivery system was developed for targeted drug delivery across the blood-brain barrier (BBB) to the brain cancer cells. A cyclic arginine-glycine-aspartic acid (RGD) peptide and transferrin (TF) were utilized as targeting ligands. Cyclic RGD peptides are specific targeting ligands o...

Tripeptide arginyl-glycyl-aspartic acid (RGD) for delivery of Cyclophosphamide anticancer drug: A computational approach

Density functional theory (DFT) calculations were performed on tripeptide arginyl-glycyl-aspartic acid (RGD) as an efficient drug carrier to deliver the commercially famous cyclophosphamide (CP) anticancer drug within ethanol solution. The most negative binding energy (-5.22 kcal/mol) was measured for the CP-RGD-7 created through the H-bond interaction between the P=O (phosphoryl) oxygen atom o...

Anti-tumor effect of RGD modified PTX loaded liposome on prostatic cancer.

In this study, we report an active targeting liposomal formulation directed by a novel peptide (RGD) that specifically binds to the integrins receptors overexpressed on prostatic cancer cells. The objectives of this study were to evaluate the in vitro and in vivo tumor drug targeting delivery of RGD modified liposomes on PC-3 cells and DU145 cells. The uptake efficiency of RGD-LP was 5.2 times ...

Formulation of temozolomide by folic acid-conjugated tri-block copolymer nanoparticles for targeted drug delivery

Introduction: Glioblastoma multiforme (GBM) is the most frequent primary malignant tumor of the brain. But, the treatment of GBM is one of the most problems in cancer therapy because of poor drug penetration across the blood-brain barrier (BBB). Targeting drug delivery system and conjugating targeting moieties was recognized to overcome the poor penetration of chemotherapy drug...
