Objective To design and synthesize the derivatives of chlorogenic acid amide dimers, and to study anti-lipid metabolic disorder activities in vitro. Methods Chlorogenic acid was used as starting material to synthesize the target compounds by three steps. The lipid-regulating activities of the compounds were tested by HepG2 cells. Results Eight chlorogenic acid dimers CGA-2a～2d and CGA-3a～3d were synthesized. The structures of the target compounds were identified by spectrum. Pharmacological results showed that compounds CGA-2d and CGA-3a～3d had different levels potency of lipid-regulating effects in cells. Conclusion The dimers CGA-2a～2d and CGA-3a～3d are new compounds, some of which have potential lipid-regulating biological activities, worthy of further development.
