Abstract

Bariatric surgery provides long-term and robust weight loss in most patients. One leading hypothesis for this profound efficacy focuses on the increased activation of gut enteroendocrine cells (EECs), resulting in enhanced secretion of satiety Hormones. We describe herein an approach using a combination of gut-targeted small molecules to stimulate intestinal nutrient receptors and mirror some of the hormone effects of bariatric surgery. In preclinical studies, administration of GPR40 agonist K-757 in combination with GPR119 Agonist K-833 resulted in robust increases in the level of circulating Hormones. In initial clinical studies, pharmacokinetics and pharmacodynamics for each molecule were characterized and largely recapitulated the effects of the individual compounds in mice.
