About the drug

Catestatin is a novel endogenous peptide that regulates cardiac function and blood pressure. Catestatin (CST) is a peptide derived by proteolytic digestion from the pro-protein Chromogranin A, a secretagogue expressed in neuroendocrine tissues and macrophages. It prevents catecholamine production by inhibiting neural acetylcholine receptor activity. As a result, CST can reduce essential hypertension.

About the patent

The invention provides methods for treating obesity in a subject comprising administrating an effective amount of CST or its equivalent to a subject afflicted with obesity so as to maintain an effective amount of circulating CST in the subject to promote lipolysis and oxidation of released fatty acids in both liver and adipose tissue, thereby, reducing adipose tissue weight and hence treating obesity in the afflicted subject.

About the application

CST will be an injectable solution in physiological saline and each injection will deliver 1 microgram CST per gm body weight. In other words, it will be 90 mg CST for a person weighing 90 kg or 200 lb. It may be injected twice daily to get more effective control of the diseases. Injection site could be subcutaneous like insulin injection.
