Dendrimer Nanoconjugates And Their Oral Inhalation Formulations For Lung Cancer Therapy, Qian Zhong

Wayne State University Dissertations

Lung cancers are leading cause of cancer death for both men and women in the world. Lungs are also one of the primary organs to which almost all cancer can spread. Chemothepray plays a crucial role in the fight against both primary lung cancers and lung metastases. Doxorubicin (DOX) is a potent anticancer drug that has been approved for treating many cancers including lung cancers. However, only a few percent of systemically administered DOX can be found in the lungs. The issue is further complicated by dose-limiting toxicity of DOX. Another major challenge in the use of DOX is its …

Dendrimer Based Nanotherapeutics For Ocular Drug Delivery, Siva Pramodh Kambhampati

Wayne State University Dissertations

PAMAM dendrimers are a class of well-defined, hyperbranched polymeric nanocarriers that are being investigated for ocular drug and gene delivery. Their favorable properties such as small size, multivalency and water solubility can provide significant opportunities for many biologically unstable drugs and allows potentially favorable ocular biodistribution. This work exploits hydroxyl terminated dendrimers (G4-OH) as drug/gene delivery vehicles that can target retinal microglia and pigment epithelium via systemic delivery with improved efficacy at much lower concentrations without any side effects.

Two different drugs Triamcinolone acetonide (TA) and N-Acetyl Cysteine (NAC) conjugated to G4-OH dendrimers showed tailorable sustained release in physiological relevant …
