and synthesized, and their antiproliferative activities against HepG2, MCF-7 cells were evaluated and described. From the activity result obtained, high to very high activity in vitro has been found, one of the tested compounds (compound 5d) exhibited the most significant cytotoxic effects. Compound 5d increased 29.2, 7.37 times anti-proliferative activity for HepG2 cells and MCF-7 cells compared to

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

analogues, of which twenty two were novel, were synthesized and evaluated for their effect to inhibit lipopolysaccharide/nigericin (LPS/NIG)-induced IL-1β release at both cell and protein levels at the concentration of 5 μM. Among them, compound 6 exhibited promising inhibitory potency against IL-β activation with an IC50 value of 3.7 μM. Preliminary mechanism study revealed that 6 might target NLRP3 protein
Twenty fangchinoline derivatives were synthesized from the natural product fangchinoline, and their anticancer activities on human breast cancer MDA-MB-231 cell line, human prostate cancer PC3 cell line, human melanoma WM9 cell line and human leukaemia HEL and K562 cell lines were evaluated. The biological result showed that those derivatives exhibited potent activities on inhibiting cancer cell growth, and the structure-activity relationships were investigated. Among them, compound 4g, which was protected by benzoyl group in 7-phenolic position and nitrified in 14-position, showed impressive inhibition on all 5 cancer cell lines, especially WM9 cell line, with an IC50 value of 1.07 µM. Further mechanistic studies demonstrated that compound 4g may induce cancer cell death by apoptotic means. These research results suggested that compound 4g could be a lead for the further development toward an anticancer agent against human melanoma WM9 in the future.
