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
Metal-Based Anti-inflammatory Drugs with High Efficacy and Low Side-Effects. Non-steroidal anti-inflammatory drugs (NSAIDs) have widespread human and veterinary applications for the treatment of arthritis and other inflammatory diseases, but their utility is limited by often severe gastrointestinal, renal and cardiac side-effects. The recently heralded COX-2 inhibitors have not lived up to their expectations in terms of efficacy and side-effects, therefore, there is a need to develop new potent ....Metal-Based Anti-inflammatory Drugs with High Efficacy and Low Side-Effects. Non-steroidal anti-inflammatory drugs (NSAIDs) have widespread human and veterinary applications for the treatment of arthritis and other inflammatory diseases, but their utility is limited by often severe gastrointestinal, renal and cardiac side-effects. The recently heralded COX-2 inhibitors have not lived up to their expectations in terms of efficacy and side-effects, therefore, there is a need to develop new potent, but safer, NSAIDs. This project is aimed at using the results from new lead compounds to design NSAIDs with much greater efficacy and much less side effects than those currently available.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.

The project builds on areas of research strength in Australia (nanotechnology and biotechnology/biomaterials) and will add considerably to the expanding Australian expertise-base in dendrimer technology (in which it is a world leader). The interdisciplinary nature of this project will also result in a unique training program for the researchers included in this grant. Such experience is in great demand, particularly in Australia where the burgeoning start-up discovery industry is critically short of personnel with skills in drug delivery.Read moreRead less
Synthetic derivatives of capsaicin and gingerols as analgesics acting at the vanilloid receptor. This project aims to prepare alpha-hydroxyketones and gingerol derivatives acting at vanilloid (VR1) receptor with potential analgesic activity. These compounds will be tested for their ability to activate the VR1 receptor, desensitize the receptor and release neuropeptides associated with pain pathways. The development of these novel compounds will contribute towards understanding the mechanisms of ....Synthetic derivatives of capsaicin and gingerols as analgesics acting at the vanilloid receptor. This project aims to prepare alpha-hydroxyketones and gingerol derivatives acting at vanilloid (VR1) receptor with potential analgesic activity. These compounds will be tested for their ability to activate the VR1 receptor, desensitize the receptor and release neuropeptides associated with pain pathways. The development of these novel compounds will contribute towards understanding the mechanisms of VR1 receptor activation and provide information on how the VR1 receptor is regulated. We will determine and compare neurotoxicity of these compounds to capsaicin which is known to possess neurotoxic activity. The outcome of this project may result in effective agents for better pain management.

Drug Delivery Devices : Hydrogels manufactured utilising Dense Gas Technologies. Many drugs are rapidly eliminated from the human body, and would benefit from being released over a long period of time. In this study, formulations to deliver drugs will be developed, using hydrogels: highly cross-linked, water saturated polymers. The polymers to be investigated are based on ingredients suitable for ingestion. Hydrogels are in common use as external therapeutic devices, such as contact lenses or wo ....Drug Delivery Devices : Hydrogels manufactured utilising Dense Gas Technologies. Many drugs are rapidly eliminated from the human body, and would benefit from being released over a long period of time. In this study, formulations to deliver drugs will be developed, using hydrogels: highly cross-linked, water saturated polymers. The polymers to be investigated are based on ingredients suitable for ingestion. Hydrogels are in common use as external therapeutic devices, such as contact lenses or wound dressings. However, hydrogels are not commonly in use as ingested drug delivery devices due to problems with the existing technologies, such as toxicity of ingredients. These problems will be addressed in this study.Read moreRead less

This project will provide technological advances with significant benefits in terms of improved drug treatment, and therefore health outcomes for Australia. The projects builds on internationally recognised research strengths at Monash University in lipid-based drug delivery, and connects Monash and Australia with applied research in the multinational pharmaceutical industry. This will enhance the standing of Australian biomedical research in the pharmaceutical world and directly facilitate a partnership between Monash and Capsugel in commercialisation of the outcomes of the project. The project will also train Australian scientists in skills that are in great demand in the developing pharmaceutical industry in Australia.Read moreRead less

The results of this research will help to advance the fundamental scientific understanding of industrially important chemical reactions and give clear leads as to how to improve them. In particular, new catalysts (i.e. agents that increase the speed and selectivity of chemical reactions) will be generated and the first steps towards process innovation will be taken, using high-throughput equipment unique in the Southern Hemisphere. These new catalysts will be the basis for the design of new and/or improved industrial processes that will be ?greener?, safer, use fewer resources, produce less waste and are generally more efficient and effective. As a result the Australian chemicals industry will be more competitive.Read moreRead less
Molecular Recognition in Chiral Ionic Liquids as Basis for the Design and Synthesis of New Enantioselective Heterogeneous Catalysts and Membranes. Molecules that can exist as mirror images, each with different, e.g., beneficial vs. toxic properties, underpin the pharmaceutical industry and increasingly new highly selective pesticides, and flavours/fragrances.

Molecules that can exist as mirror images, each with different, e.g., beneficial vs. toxic properties, underpin the pharmaceutical industry and increasingly new highly selective pesticides, and flavours/fragrances.
Current commercial pathways often make mixtures of the mirror images that then need to be separated laboriously. These routes are inefficient, creating waste and use resources poorly.
We aim to create solutions for these problems, using supported thin films of special, new types of salts that are liquid at room temperature, and which have other unusual chemical properties that make them ideally suited to enable efficient conversions.Read moreRead less
