Book Description
The opportunities and challenges of using dendrimers to improve drug delivery Among pharmaceutical and biomedical researchers, the use of dendrimers in drug delivery systems has attracted increasing interest. In particular, researchers have noted that the volume of a dendrimer increases when it has a positive charge. If this property can be applied effectively, dendrimers have enormous potential in drug delivery systems, directly supplying medication to targeted human organs. With contributions from an international team of pioneers and experts in dendrimer research, this book provides a comprehensive overview of the latest research efforts in designing and optimizing dendrimer-based drug delivery systems. The book analyzes key issues, demonstrating the critical connections that link fundamental concepts, design, synthesis, analytical methodology, and biological assessment to the practical use of dendrimers in drug delivery applications. Topics covered include: Dendrimer history Synthesis Physicochemical properties Principles of drug delivery Applications in diverse biomedical fields Dendrimer-Based Drug Delivery Systems reflects the authors' thorough review and analysis of the current literature as well as their own firsthand experience in the lab. Readers will not only discover the current state of the science, but also gain valuable insights into fruitful directions for future research. References at the end of each chapter serve as a gateway to the growing body of literature in the field, enabling readers to explore each individual topic in greater depth. Pharmaceutical and biomedical researchers will find this book a unique and essential guide to the opportunities, issues, and challenges involved in fully exploiting the potential of dendrimers to improve drug delivery.

Book Description
Today, drugs used in treating disease are almost all hydrophobic, which makes them unattractive for applying to patients. To overcome this problem, an amphiphilic macromolecule was designed which can deliver drugs to the specific targeted area. Therefore, this study focuses on the synthesis of water soluble hyperbranched polymers and their application in drug delivery systems. The first part of the thesis describes the synthesis of water soluble hyperbranched polymers by the anionic-polymerisation technique, with p-nitrophenol as the core and glycidol as the monomer. The core is important to control the molecular weight of the hyperbranched polymer. We then produced five different molecular weights by varying the core to monomer ratio, which produced hyperbranched polymers with molecular weights of 4000 Da, 8000 Da, 12500 Da, 27000 Da and 50000 Da, and four different concentrations of each molecular weight, 1.00 x 10-4 M, 2.00 x 10-4 M, 4.00 x 10-4 M and 6.00 x 10-4 M. To investigate the performance of the hyperbranched polymers, four different hydrophobic molecules were studied. The molecules were naphthalene, ibuprofen, tetracarboxyphenyl porphyrin (TCPP) and anti-prion drug. Encapsulation studies showed the concentration of each molecule increased with an increase in molecular weight and concentration of the hyperbranched polymer The functionalisation of folic acid on the surface of the hyperbranched polymer would enhance the effectiveness of the polymer as a drug delivery agent for targeting in cancer treatment. The above macromolecule was synthesised by conjugation with folic acid through poly (ethylene glycol) as spacer. The final chapter of this work describes the encapsulation of two hydrophobic molecules, ibuprofen and tetracarboxyphenyl porphyrin with water soluble PAMAM dendrimers. PAMAM dendrimers from G0.5 to G2.5 were synthesised. The results showed that more drug solubilised, the concentration of both molecules increased with an increase in dendrimer concentration. Then a comparison was made between encapsulation with water soluble hyperbranched polymers and water soluble PAMAM dendrimers. Similar molecular weight was used for both polymers of 4000 Da. For both polymers, the result demonstrated that the concentration of drug rose at 2.00 x 10-4 M and plateaued at a polymer concentration of 6.00 x 10-4 M. It was suggested the above trend was due to the aggregation of polymer. The above studies make a valuable contribution to the development of good drug delivery systems.
