Fangchinoline derivatives inhibits PI3K signaling in vitro and in vivo in non-small cell lung cancer.

Fangchinoline (Fan) are extracted from the traditional Chinese medicine Stephania tetrandra S., which is a bis-benzyl isoquinoline alkaloids with anti-tumor activity. Therefore, 25 novel Fan derivatives have been synthesized and evaluated for their anti-cancer activity.

Design, synthesis and in vitro anticancer research of novel tetrandrine and fangchinoline derivatives.

Cancer treatment is one of the major public health issues in the world. Tetrandrine (Tet) and fangchinoline (d-Tet) are two bis-benzyl isoquinoline alkaloids extracted from Stephania tetrandra S. Moore, and their antitumor activities have been confirmed.

Design, synthesis and in vitro evaluation of fangchinoline derivatives as potential anticancer agents.

The isolation and modification of natural products play an important role in the synthesis of anti-tumor drugs for the treatment of cancer. The present study was designed to evaluate the effects of fangchinoline derivatives against cancer cells. In vitro cytotoxicity of all derivatives against five cancer cell lines (A549, Hela, HepG-2, MCF-7 and MDA-MB-231 cell lines) and HL-7702 normal cells was assessed using the CCK-8 assay, and the results showed that most of the synthesized compounds displayed better cytotoxic effects on all the tested cells compared to that of the parent fangchinoline.
