Abstract:

In order to explore more effective anti-tumor drugs, and improve the anti-tumor activities of tetrandrine, six new bisbenzylisoquinoline derivatives of tetrandrine were designed and synthesized by Suzuki coupling. The structures of these compounds were confirmed by 1H nuclear magnetic resonance(1H NMR),13C nuclear magnetic resonance(13C NMR), and mass spectrometry(MS). Their inhibitory activities against human lung cancer cells(A549) and murine leukemia cells(P388) were evaluated by CCK-8(cell counting kit-8) method. All these compounds exhibit a certain level of anti-tumor activities, while compounds H1, H4, H6 possess better cytotoxicity profile than tetrandrine against A549 cells.

Key words: tetrandrine, Suzuki coupling reaction, cell counting kit-8 method, anti-tumor activity
