Development of Liposaccharide Peptide Conjugates for Peptide Drug Delivery. We aim to adapt the Solid Phase Oligosaccharide Synthesis technology patented by Alchemia to develop methodologies that will allow the assembly of sugar, lipid and peptide units on a single solid phase resin. This synthetic technology will then be used to generate a library of liposaccharide conjugates of two model peptides (LHRH and TRH) to investigate and optimise a broadly applicable peptide drug delivery system whic ....Development of Liposaccharide Peptide Conjugates for Peptide Drug Delivery.

By applying modern techniques and a multidisciplinary approach, this research will develop an understanding of drug loading of BioSiliconTM at a molecular level. This novel class of nano-structured biomaterial has exciting potential for developing a range of controllable drug delivery systems. Existing medical applications of BioSilicon deliver only small molecules for very specialised uses. Current research has not focused on understanding the pore structure and how it can be adapted for special applications. Our research will create new drug delivery systems with many innovative applications in medical, veterinary and bio-diagnostics fields. The medical and socio-economic impacts will be internationally significant.Read moreRead less
A combinatorial approach to creation of new epitopes with biological activity. We aim to develop and extend the Mosaic technology patented by Proxima Concepts Ltd. as a new methodolgy for dynamic combinatorial chemistry and drug delivery. The technology relies on bringing chemical structures of interest in close proximity by presenting them on the surface of a micelle type structure. These structures will also be developed at a targeted drug delivery vehicle. The technology will impact on the ....A combinatorial approach to creation of new epitopes with biological activity.

BIOCATALYSTS MINED FROM CYTOCHROME P450 LIBRARIES: AN INNOVATIVE TOOL FOR ACCELERATING DRUG DEVELOPMENT. The cytochrome P450s (P450s) are a family of enzymes that are perhaps the most versatile biological catalysts known. DNA shuffling is an emerging technique that takes the genes encoding families of enzymes and creates libraries of catalysts with both improved and novel properties. We will obtain proof of concept that shuffled P450 libraries can be screened and optimized for use as biocatalys ....BIOCATALYSTS MINED FROM CYTOCHROME P450 LIBRARIES: AN INNOVATIVE TOOL FOR ACCELERATING DRUG DEVELOPMENT. The cytochrome P450s (P450s) are a family of enzymes that are perhaps the most versatile biological catalysts known. DNA shuffling is an emerging technique that takes the genes encoding families of enzymes and creates libraries of catalysts with both improved and novel properties. We will obtain proof of concept that shuffled P450 libraries can be screened and optimized for use as biocatalysts in drug development. The methodologies developed here will overcome two critical bottlenecks in current drug development: the optimisation and metabolic profiling of new drug candidates. This will yield important benefits in accelerating the optimisation and safety testing of drugs under development.Read moreRead less
Enhanced drug delivery using nanoparticulate dendrimer vectors. Many drug candidates fail during development because of low and variable absorption after oral administration. This project seeks to investigate the utility of specialised nanometer-sized macromolecules (dendrimers), to facilitate the improved delivery of drug molecules where low aqueous solubility is the principle limitation to drug absorption and will also be explored as vectors to specifically target drugs to intestinal lymphoid ....Enhanced drug delivery using nanoparticulate dendrimer vectors. Many drug candidates fail during development because of low and variable absorption after oral administration. This project seeks to investigate the utility of specialised nanometer-sized macromolecules (dendrimers), to facilitate the improved delivery of drug molecules where low aqueous solubility is the principle limitation to drug absorption and will also be explored as vectors to specifically target drugs to intestinal lymphoid (immune) tissue. This project will link the drug delivery expertise of Monash University with the experience in dendrimer design of the Australian biotechnology company Starpharma to provide concrete delivery solutions for the rapidly expanding biotechnology industry in Australia.Read moreRead less
Systematic evaluation of whether in vitro methods can predict in vivo opioid analgesic efficacy, safety and tolerability. It is estimated that chronic pain affects one in five individuals in the general community in Australia and worldwide, with prevalence rates correlated directly with advancing age. Chronic pain not only adversely affects the quality of life of individuals but it also places a large economic burden on our healthcare system. Development and validation of an in vitro method to ....Systematic evaluation of whether in vitro methods can predict in vivo opioid analgesic efficacy, safety and tolerability. It is estimated that chronic pain affects one in five individuals in the general community in Australia and worldwide, with prevalence rates correlated directly with advancing age. Chronic pain not only adversely affects the quality of life of individuals but it also places a large economic burden on our healthcare system. Development and validation of an in vitro method to successfully identify novel morphine-like strong analgesics with a reduced propensity for producing respiratory depression or constipation, has the potential to not only improve pain management for individuals and to reduce the economic burden of chronic pain on the Australian healthcare system, but it is also likely to produce direct economic benefits to our nation.

Oral Insulin Delivery facilitated by Enteric Coating using Dense Gas Technologies. Insulin dependant diabetes is a rapidly growing disease. The current method for insulin delivery to the patient is by injection, which is inconvenient. Oral delivery of insulin is a more acceptable method. It is proposed to develop a dense gas technique to coat insulin with a pH sensitive polymer to protect it from the acidic environment of the stomach. Insulin can then be released at the high pH of the intestin ....Oral Insulin Delivery facilitated by Enteric Coating using Dense Gas Technologies. Insulin dependant diabetes is a rapidly growing disease. The current method for insulin delivery to the patient is by injection, which is inconvenient. Oral delivery of insulin is a more acceptable method. It is proposed to develop a dense gas technique to coat insulin with a pH sensitive polymer to protect it from the acidic environment of the stomach. Insulin can then be released at the high pH of the intestine when the polymer is dissolved. Particle size control is feasible by dense gas processes by manipulating operating parameters. Advantages include low residual solvent and manufacture at ambient temperatures.Read moreRead less
