Cisd2 agonist 2 (compound 6), with an EC50 of 191 nM, is an orally active activator of Cisd2, a protein whose levels are associated with nonalcoholic fatty liver disease (NAFLD). In vivo studies have demonstrated that Cisd2 agonist 2 exhibits no significant toxicity in heterozygous hepatocyte-specific Cisd2 knockout (Cisd2hKO-het) mice [1].
