Abstract: Taking cytosine, an unique natural product alkaloid as the lead, we designed thirty cytisinic derivatives with different types of 12N-substituents, which were synthesized and evaluated for their activity in the regulation of glucose metabolism in vitro. The compounds 3d, 3g and 6h exhibited the potential hypoglycemic activity and compound 3d had a good pharmacokinetics profile. In terms of mechanism of glucose consumption, the compounds 3d and 6h increased cellular glucose consumption. which might be associated with up-regulation of glucose transporter Glut4 expression and activation of AMPK. The results revealed important roles of these new skeleton compounds as potential new drug candidates for control of blood glucose.
