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

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.

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
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

The proposed environmentally friendly technology has broad applications for improving properties of various polymeric matrices used for biomedical applications. The process developed would value-add for manufacturing biomedical polymeric devices in Australia with licensing of existing fabrication methods as a best option. Moreover, the leading-edge polymer technology developed would minimise the organic solvent consumption and will attract business from international polymer and biotechnology companies for production of implant and drug delivery devices. The development of world-class research provides Australia with recognition as a world leader in the field and broadens the knowledge based of Australian scientist and engineers.Read moreRead less

The demand for novel effective, orally available medicines to treat a wide range of diseases (cancer, pain - ageing Australian population) is increasing exponentially. Conjugation of peptide drug or vaccine candidates with lipids and/or sugars represents an important, novel strategy in the drug delivery and targeting field. Increasing the lipophilicity improves absorption through intestinal mucosal membranes. The carbohydrates increase the compound's aqueous solubility and can utilize active transport systems and can target the site required for its biological function. There is no limit to the areas of medicine and public health that would benefit from this revolutionary new technology.Read moreRead less
Guiding ligands to nuclear receptors: The role of fatty acid binding proteins. Considerable recent effort has been directed towards the development of Australia as a focal point for biotechnology and drug discovery. The principal operational focus of this effort has been the identification of potent and active new chemical entities. In order for these new molecules to be most useful in the community, however, they must be active after oral administration.

Considerable recent effort has been directed towards the development of Australia as a focal point for biotechnology and drug discovery. The principal operational focus of this effort has been the identification of potent and active new chemical entities. In order for these new molecules to be most useful in the community, however, they must be active after oral administration. This project will examine the fundamental mechanisms by which drugs are absorbed across the cells lining the intestine and will provide insight critical to the design and development of new drugs that are both potent and orally active.Read moreRead less
