Several routes shinee symptoms generic 100mg dilantin overnight delivery, including intramuscular medicine jokes buy discount dilantin 100mg on line, subcutaneous symptoms kidney cancer order dilantin 100mg with mastercard, intravenous, intradermal, nasal, and oral administration, have been investigated for the administration of genetic vaccines. Of these routes, intramuscular injection of genetic vaccines generated the best response. Mature myotube has been shown to be the target for the uptake of plasmid after intramuscular administration. Plasmid can enter the bloodstream and lymphatic system after intramuscular administration and traffic to the spleen, liver, kidney, lymph nodes and bone marrow. It is not clear whether the production of antigens in muscle has unique properties with respect to the elicitation of a prolonged immune response or whether expression in any tissue in the periphery is sufficient for the induction of an antigen-specific immune response. Single injection provides for a full humoral and T cell response for 60–70 weeks, with the antibody titer being higher than that achieved by intramuscular injection. Skin is rich in dendritic cells, which are potent initiators of immune responses and possess the co- stimulatory and adhesion molecules required for T cell activation. Thus, transfection of plasmids into these cells is likely to elicit both cellular and humoral responses. Specific targeting of dendritic cells residing in the lymph nodes will likely represent an attractive strategy for providing a robust immune response with nucleic acid vaccines. Plasmid-based (or non-viral) gene therapy has generated considerable research interest because of many inherent advantages over the viral vectors in terms of safety, immunogenicity and ease of manufacture. Gene therapy offers unique opportunities in the development of novel products that produce intracellular proteins. Several plasmid-based approaches are already in clinical trials and offer the potential of safe and effective gene therapy. To enhance the therapeutic efficacy of 356 proteins using plasmid-based expression systems, many fundamental questions related to their pharmaceutical formulation, biodistribution and intracellular trafficking still need to be addressed. Describe the pharmacodynamic and pharmacokinetic barriers to effective plasmid-based gene delivery. Outline the various approaches to cancer gene therapy presently being investigated. Traditionally new chemical entities have been identified by the screening of natural products and chemical libraries to identify potential lead compounds. These lead compounds have then been optimized through an iterative lead-optimization process involving the synthesis of analogs, the development of quantitative-structure-activity relationships and the use of molecular modeling to obtain new chemical entities with high specificity and affinity for the therapeutic target for pharmaceutical development. The development of combinatorial chemistry has led to the ability to produce vast libraries of compounds for initial screening. The evaluation of combinatorial libraries using high-throughput screening technologies allows the rapid screening of potential lead compounds with a wider molecular diversity against a broad range of therapeutic targets. Until recently, therapeutic targets were identified through the application of basic pharmacology and biochemistry with both receptor and enzyme targets being identified and isolated from specific tissues. The identification of potential therapeutic targets has been further enhanced through the recent development of genomics and proteomics. These techniques provide mechanisms to identify upregulated gene and protein expression in diseased tissue providing pointers towards potential means of therapeutic intervention. The advances in molecular biology have also led to the ability to clone receptors into various cell types to facilitate screening of potential ligands against such targets. The parallel development of cell biology has led to the ability to utilize cell-based assays rather than tissue-based assays for drug screening and the advances in robotics have led to the development of high-throughput screening technologies. The development of genomics, proteomics, high-throughput screening and combinatorial chemistry has led to an information explosion within pharmaceutical companies requiring better mechanisms for the storage and manipulation of biological and chemical data. This has driven the development of the field of bioinformatics which serves to provide searchable databases allowing comparison of molecular and biological information to potentially identify other therapeutic targets and lead compounds. This chapter aims to provide a brief overview of these different technologies to provide a basis for the reader to develop their understanding of this field in order to appreciate how these technologies will underpin the future of drug delivery and targeting. The majority of combinatorial approaches utilize polymeric solid supports as a base onto which the compounds are synthesized. However, there are also approaches which utilize solution- based chemistries to generate combinatorial libraries. Such supports are traditionally composed of polymeric resin beads on to which the synthesis of a peptide is undertaken in a stepwise fashion with each amino acid being added sequentially to the peptide chain (Figure 15.
