Studies on the stereospecific interaction between aldose reductase and inhibitor. There is no therapy specific for treatment of diabetes complications accepted worldwide. The enzyme aldose reductase has shown promising results as a drug target for preventing or delaying the onset of the complications. The structures of human aldose reductase holoenzyme in complex with stereoisomers of the potent inhibitor Fidarestat will be determined at high resolution in order to elucidate the binding modes re ....Studies on the stereospecific interaction between aldose reductase and inhibitor. There is no therapy specific for treatment of diabetes complications accepted worldwide. The enzyme aldose reductase has shown promising results as a drug target for preventing or delaying the onset of the complications. The structures of human aldose reductase holoenzyme in complex with stereoisomers of the potent inhibitor Fidarestat will be determined at high resolution in order to elucidate the binding modes responsible for the differences in their inhibitory potencies. The results may lead to the design of better inhibitors of the enzyme for the treatment of diabetes sufferers, at least until better methods for maintaining metabolic control are developed.Read moreRead less
Structure-based discovery of dipeptidyl peptidase IV inhibitors. Diabetes afflicts approximately 151 million people worldwide, with an estimated increase to 221 million by 2010. To date, no therapy for the treatment of diabetes complications is widely accepted. The enzyme dipeptidyl peptidase IV has shown promising results as a target for the treatment of type 2 diabetes. Structural studies of dipeptidyl peptidase IV in complex with inhibitor will be conducted to elucidate the details of the e ....Structure-based discovery of dipeptidyl peptidase IV inhibitors. Diabetes afflicts approximately 151 million people worldwide, with an estimated increase to 221 million by 2010. To date, no therapy for the treatment of diabetes complications is widely accepted. The enzyme dipeptidyl peptidase IV has shown promising results as a target for the treatment of type 2 diabetes. Structural studies of dipeptidyl peptidase IV in complex with inhibitor will be conducted to elucidate the details of the enzyme-inhibitor interaction. The results will be used to identify the molecular basis of potency and selectivity of dipeptidyl peptidase IV inhibitors and may lead to the discovery of pharmaceutical agents for the treatment of diabetes sufferers.Read moreRead less
Crystallographic studies of aldose and aldehyde reductases. The ability of aldose reductase to reduce the excess glucose that results from the hyperglycaemia of diabetes has been linked to the development of diabetic complications. Recent studies link the lack of a clinically suitable aldose reductase inhibitor to lack of inhibitor selectivity. The structures of the complexes of aldose and aldehyde reductases with various inhibitors should allow us to establish the important aspects of the inh ....Crystallographic studies of aldose and aldehyde reductases. The ability of aldose reductase to reduce the excess glucose that results from the hyperglycaemia of diabetes has been linked to the development of diabetic complications. Recent studies link the lack of a clinically suitable aldose reductase inhibitor to lack of inhibitor selectivity. The structures of the complexes of aldose and aldehyde reductases with various inhibitors should allow us to establish the important aspects of the inhibitor interaction with the residues of the active site. This information will be used in the design of more specific aldose reductase inhibitors.Read moreRead less
Insulin-like growth factor binding proteins: structure and ligand interactions. Insulin-like growth factors are important for normal growth and development. Their actions are regulated by a family of IGF binding proteins. In order to understand the mechanism of this regulation, the aim of this project is to determine the 3-dimensional structure of 2 IGFBPs in complex with IGFs. This will lead to a comprehensive understanding of this interaction that promises to provide important basic knowledge ....Insulin-like growth factor binding proteins: structure and ligand interactions.

A Facility for High-Throughput, Functional Gene Discovery Using Arrayed Retroviral Expression Cloning. The proposed facility will represent world-leading technology in functional genomics and provide Australian scientists with unique opportunities to identify genes involved in a broad range of biological processes. This will contribute to fundamental knowledge in mammalian biology, and equally importantly, is likely to identify genes involved in important health problems such as cancer, inflamma ....A Facility for High-Throughput, Functional Gene Discovery Using Arrayed Retroviral Expression Cloning. The proposed facility will represent world-leading technology in functional genomics and provide Australian scientists with unique opportunities to identify genes involved in a broad range of biological processes. This will contribute to fundamental knowledge in mammalian biology, and equally importantly, is likely to identify genes involved in important health problems such as cancer, inflammatory disease, brain damage and diabetes. Such genes may in turn constitute targets against which new therapies may be developed. This endeavour will contribute to national research priorities in both the health and scientific/technological development arenas.Read moreRead less
