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.

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.

The project has broad benefits for the nation and the community. Cutting edge research at the molecular level, done within Australia, will benefit Australian scientists and research in general. The discovery of drugs that will be developed by the Australian Pharmaceutical Industry will benefit the Australian Industry sector and will have spin-offs for the racing industry, livestock industry (lean meat) and for rural industry (insecticides). In addition, expansion of the outcomes of the project into preclinical development will strengthen the Australian bioscience sector. Thus the project will eventually benefit the Australian industry sector. The project will have further benefits for education and training. Read moreRead less
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.

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 which improves peptides oral absorption, metabolic stability and bioavailability.Read moreRead less
CHARGED LIPOSACCHARIDE BASED DRUG DELIVERY SYSTEM. Complexation of a drug with lipid and/or sugar units represents one of the most important of the strategies being investigated in this burgeoning field. Increasing the lipid solubility of a hydrophilic compound has been established as an important factor in improving its absorption as it is necessary for passive transport across intestinal mucosal membranes. The role of sugar unit is very important: (i) it modifies the physico-chemical propertie ....CHARGED LIPOSACCHARIDE BASED DRUG DELIVERY SYSTEM. Complexation of a drug with lipid and/or sugar units represents one of the most important of the strategies being investigated in this burgeoning field. Increasing the lipid solubility of a hydrophilic compound has been established as an important factor in improving its absorption as it is necessary for passive transport across intestinal mucosal membranes. The role of sugar unit is very important: (i) it modifies the physico-chemical properties (solubility), (ii) utilizes active transport systems (e.g. Glucose transport) and (iii) target the compound - "MAGIC BULET" (Lewis X analogues - damaged cells). There is no limit to the areas of medicine and public health that would benefit from revolutionary new technology in these areas.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
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
Rational Design of Pegylated Dendrimer Nanostructures for Site Specific Drug Delivery. This project will provide technological advances with significant benefits in terms of improved drug treatment, and therefore health outcomes for Australia.

In addition, there is considerable research being conducted on peptide development for a range of diseases and there may be a possibility of delivering these by the skin.
This work, in seeking to understand some of the fundamental determinants governing how exogenously applied peptides distribute in the skin, is also contributing to the development of Australian pharmaceutical and cosmetic industries.Read moreRead less
