Abstract:
The present study was designed to synthesize and evaluate a series of benzylisoquinoline derivatives. These compounds were synthesized by Bischler-Napieralski cyclization to yield 1-benzyl-3,4-dihydroisoquinolines, and the products were obtained by reductions. All these compounds were identified by MS, (1)H NMR and (13)C NMR. The inhibitory activities on pancreatic lipase and preadipocyte proliferation for the synthesized compounds and alkaloids from Nulembo nucifera were assessed in vitro. Most of the compounds showed inhibitory activities on both pancreatic lipase and preadipocyte proliferation. Particularly, compounds 7p-7u and 9d-9f exhibited significant inhibitory activity on pancreatic lipase while compounds 7c, 7d, 7f, 7g, 7i, and 7j potently inhibited the proliferation of 3T3-L1 preadipocytes. Our results provided a basis for future evaluation and development of these compounds as leads for therapeutics for human diseases.
