AS 1842856 is a potent and selective Foxo1 inhibitor (IC50 values are 33 nM at Foxo1 and >1 μM at Foxo3a and Foxo4); decreases Foxo-mediated promoter activity by 70%, 20% and 3% at Foxo1, Foxo4 and Foxo3, respectively. Regulates gluconeogenesis both in vitro and in vivo. Attenuates fasting plasma glucose level in diabetic db/db mice. Also suppresses autophagy, adipocyte differentiation and soluble guanylyl cyclase expression.
