EVALUATION OF THE ACTIVITY OF A NOVEL PARTIAL AGONIST OF A1 ADENOSINE RECEPTOR AS POTENTIAL THERAPEUTIC AGENT FOR DIABETES AND OBESITY

Adenosine A1 receptor (A1R) agonists as anti-lipolytic agents and enhancers of tissue insulin sensitivity could be useful in the treatment of metabolic disorders but their use is limited by unwanted cardiac effects and tachyphylaxis. Partial A1R agonists can overcome these problems, while maintaining significant anti-lipolytic effects due to greater A1R reserve in the adipose tissue.
Based on preliminary data, this research, carried out either in in vitro (human and rat adipocytes, adipose stem cell, isolated heart and vessels) or in vivo models (healthy, diabetic, diabetic-obese rats), will study a new adenosine derivative with chemical features different from previous partial A1R agonists, good affinity and selectivity at human A1R, that could show antilipolytic/antidiabetic and also anti-adipogenic activities and less ability to cause cardiovascular side-effects and receptor desensitization. This evidence would be crucial for its use in chronic treatment of metabolic syndromes.
