Use of Englerin A, a Small Molecule HSF1 Activator, for the Treatment of Diabetes, Obesity, and Other Diseases Associated with Insulin Resistance
Insulin resistance is a causative factor for type 2 diabetes, obesity and a number of other conditions. This technology claims methods for treating diseases or conditions associated with insulin resistance using the small molecule epoxy-guaiane derivative englerin A and related compounds. The compounds are claimed separately in a related NIH technology.
The inventors have shown that englerin A, a compound originally isolated from the Phyllanthus plant and previously identified as an anti-cancer agent, can also be used to treat insulin resistance. Insulin resistance is associated with reduced gene expression and production of heat shock protein 70 (HSP70). Using a mouse with tumor model, the inventors discovered that administration of englerin A decreases blood glucose levels by activating transcription of HSF1, thereby increasing the expression and secretion of HSP70. Thus, englerin A and related compounds represent potential drugs for the treatment of a variety of conditions associated with insulin resistance.
|Potential Commercial Applications:||Competitive Advantages:||Treatment of diseases or conditions associated with insulin resistance, such as type 2 diabetes, obesity, inflammation, metabolic syndrome, polycystic ovary disease, arteriosclerosis, non-alcoholic fatty liver disease, reproductive abnormality of a female, and growth abnormality.||Use of small-molecule compounds targeting HSF1 represents a novel approach to the treatment of type 2 diabetes and other conditions caused by insulin resistance.|
