The Antioxidant And Antimicrobial Activities Of Cornsilk Extract Encapsulated In Polysaccharide Nanoparticles, Maryam Mady
The Antioxidant And Antimicrobial Activities Of Cornsilk Extract Encapsulated In Polysaccharide Nanoparticles, Maryam Mady
Theses and Dissertations
Corn silk possess antibacterial and antioxidant activities due to its phenolic compounds but they are of low bioavailability that requires some innovative techniques to develop such active ingredients in a safe and less toxic manner. Accordingly, silk extract SE was encapsulated in chitosan nanoparticles CS NPs, which is a natural and abundant polymer derived from chitin. Among 15 experimental trials via design expert software, the optimum formula of SE x\CS NPs was prepared at 800 rpm, 5hrs. on magnetic stirrer, and by CS: TPP ratio was 2.5:1. Then SEM showed the majority of particles size diameter in the range of …
Exploring Efficacy Of An Anti-Malarial Nanomedicine In Non-Small Cell Lung Cancer Treatment, Vineela Parvathaneni
Exploring Efficacy Of An Anti-Malarial Nanomedicine In Non-Small Cell Lung Cancer Treatment, Vineela Parvathaneni
Theses and Dissertations
New drug and dosage form development faces significant challenges, especially in oncology, due to longer development cycle and associated scale-up complexities. Repurposing of existing drugs with potential anti-cancer activity into new therapeutic regimens provides a feasible alternative. In this project, amodiaquine (AQ), an anti-malarial drug, has been explored for its anti-cancer efficacy through formulating inhalable nanoparticulate systems using high-pressure homogenization (HPH) with scale-up feasibility and high reproducibility. A 32 multifactorial design was employed to better understand critical processes and formulation parameters so as to ensure product quality with improved anticancer efficacy in non-small cell lung cancer (NSCLC). Optimized AQ loaded …
Double-Coated Biodegradable Poly (Butyl Cyanoacrylate) Nanoparticulate Delivery Systems For Brain Targeting Of Doxorubicin Via Oral Administration, Neeraj Kaushal
Theses and Dissertations
Primary brain cancer cells grow within the brain or cancer cells can metastasis from different site of the body into brain. The major hurdle in the treatment of brain cancer is the presence of blood-brain barrier (BBB). Additionally, acquired multidrug-resistant (MDR) impedes the success of long-term chemotherapy. Therefore, the objective of this investigation is to evaluate the brain targeting potential of orally administered poly(butyl cyanoacrylate) nanoparticulate delivery systems (PBCA-NPDS), double-coated with Tween 80 and polyethylene glycol (PEG) 20000 for brain delivery of doxorubicin, that does not cross the BBB by itself. And, evaluate the MDR reversal potential of PBCA-NPDS. Doxorubicin-loaded …
Amphiphilic Cell-Penetrating Peptides Containing Natural And Unnatural Amino Acids As Drug Delivery Tools And Antimicrobial Agents, David Salehi
Pharmaceutical Sciences (MS) Theses
Cell-penetrating peptides containing arginine as positively charged residues and tryptophan or diphenylalanine as hydrophobic residues were synthesized. The synthesis was accomplished through the Fmoc solid-phase peptide synthesis in the presence of HBTU and DIPEA. The side-chain protected linear peptides were cleaved from the resin and cyclized in the presence of DIC and HOAt in the solution phase overnight. MALDI-TOF mass spectrometry was used to characterize the peptides.
The cytotoxicity of the synthesized peptides was determined in CCRF-CEM (human, lymphoblast peripheral blood), and HEK-293 (human, embryonic epithelial kidney healthy) cells using the MTS assay. A concentration of 10 µM was found …
