Download or read book Nanocapsule based Protein Delivery Platforms for Overcoming Biological Barriers written by Di Wu and published by . This book was released on 2018 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the most dynamic and diverse macromolecules in our body, proteins perform a vast array of function, such as catalyzing metabolic reactions, forming receptors and channels for transportation, responding to stimuli and etc. In this context, tremendous opportunities are provided in harnessing proteins for therapeutic and diagnostic purposes. However, there are still challenges in the development and delivery of protein therapeutics. For instance, the vulnerable nature of proteins with poor stability lead to alternation of protein architects during delivery process which hindered its application. In addition, the low permeability of native protein though biological barriers (e.g., cell membrane, the mononuclear phagocyte system, blood brain barrier, etc.) prevents the successful delivery and efficient response of protein therapeutics. Therefore, development of novel protein delivery platforms, which can stabilize proteins and overcome biological barriers, will broaden the utility of protein therapeutics. In this dissertation, novel platforms for protein delivery have been developed based on the protein nanocapsule technology, which is achieved by encapsulating the protein molecules with a thin polymer network via in situ polymerization. Such protein delivery platform can significantly improve the protein stability as well as endow various surface properties (e.g., cationic charge, stealth surface, specific targeting capability, etc.) to overcome different biological barriers. Based on this technology, we enable to rationally design and synthesize nanocarriers, understand and precisely control behaviors during transportation process through the biological barriers. This dissertation can be outlined with the following three topics: 1) Fully understand and precisely control the kinetics of intracellular protein delivery. In this part, FLuc nanocapsules, which can mimic current strategies for intracellular delivery, was employed as a probe to real-time quantify the internalization process. By realizing precisely spatiotemporal control over distribution and functions, this platform provides a simple and efficient approach for optimization of dosimetry, characterization of therapeutic efficiency and screening of novel medicine. 2) Overcome the mononuclear phagocyte system to deliver protein therapeutics with prolonged circulation time and reduced immunogenicity. In this work, another FLuc nanocapsule with stealth surface was developed. The probe improves FLuc stability, reduces the immune clearance, prolongs the circulation time and present a high contrast imaging of the tumor. This method provides an effective and safe route for tumor diagnosis. Overall, this dissertation established various novel strategies toward better protein delivery platforms for overcoming biological barriers, which broaden the application of protein therapeutics.

Available in PDF, EPUB and Kindle. Book excerpt: Protein are the most dynamic and diverse macromolecules in living organisms, taking part in almost every biological reaction. While burst progresses have been made in revealing new pathways mediated by proteins and understanding of protein functions, their clinical applications are still limited due to the biological barriers that in vivo protein delivery encounters. Although strategies based on nanoparticles have been introduced to address this problem, failure in overcoming all the barriers simultaneously could lead to the compromised delivery efficacy. Therefore, development of delivery platforms that can effectively overcome those biological barriers comprehensively would help realize their potential into practical applicationsIn this dissertation, novel strategies have been developed for protein delivery based on coacervate nanoreactors or sheddable PMPC conjugated nanocomplexes depending on the target site of protein therapeutics. This dissertation research consists with two topics outlined below: 1. Realize the co-delivery of enzyme cascade to bloodstream. In this part, we combined the strategy of coacervate complex with in situ polymerization to encapsulate enzyme cascade in a coacervate nanoreactor with crosslinked zwitterionic shell. Such structure and surface property enhanced the overall catalytic efficacy, elimination of reaction intermediates, enzymatic stability, and prolonged circulation time of the enzyme cascade, providing a protein delivery platform for enzyme replacement therapy. 2. Realize the systemic delivery of intracellularly functional protein to tumor. In this part, we combined the strategy of "stealth" surface with cell-permeable nanocapsule to construct a nanocomplex with a PMPC shell. The nanocomplex facilitated overcome the biological barriers of immune clearance, tumor accumulation and penetration, cellular internalization, and endosomal escape, displaying an effective tumor inhibition. Overall, this dissertation utilized various strategies and developed novel protein delivery platforms for overcoming biological barriers and improving the bioavailability of protein therapeutics, which broadens their applications.

Available in PDF, EPUB and Kindle. Book excerpt: Proteins are still gaining importance in the pharmaceutical world, where they are used to improve our arsenal of therapeutic drugs and vaccines and as diagnostic tools. Proteins are different from "traditional" low-molecular-weight drugs. As a group, they exhibit a number of biopharmaceutical and formulation problems. These problems have drawn considerable interest from both industrial and aca demic environments, forcing pharmaceutical scientists to explore a domain previ ously examined only by peptide and protein chemists. Biopharmaceutical aspects of proteins, e.g., low oral bioavailability, have been extensively investigated. Although all possible conventional routes of ad ministration have been examined for proteins, no real, generally applicable alter native to parenteral administration in order to achieve systemic effects has yet been discovered. Several of these biopharmaceutical options have been discussed in Volume 4 of this series, Biological Barriers to Protein Delivery. Proteins are composed of many amino acids, several of which are notorious for their chemical instability. Rational design of formulations that optimize the native structure and/or bioactivity of a protein is therefore of great importance when long shelf life is required, as it is for pharmaceutical products. This issue has also been examined in two prior volumes of this series: Volume 2: Stability of Protein Pharmaceuticals (Part A) and Volume 5: Stability and Characterization of Protein and Peptide Drugs.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in biotechnology have provided scientists with an increasing number of biopharmaceuticals such as novel peptide and protein drugs as well as nucleic acid based drugs for gene therapy. However, successful delivery of these biopharmaceuticals is a major challenge because their molecular properties lead to poor physical and chemical stability in the body and limited membrane permeability. Therefore researchers are developing a range of new delivery technologies and materials to enable these new drugs to be delivered intact to their target sites. Delivery Technologies for Biopharmaceuticals describes strategies to overcome the main barriers for successful delivery of therapeutic peptides, proteins, and nucleic acid-based drugs or vaccines related to the site of administration and the target site. Many of the approaches described are reported in formulations in current clinical trials as well as in marketed products.
