, (2019/03/15)
The invention a Combretastatin A4 analogue containing a cyanoethylene joining chain and an application in preparing antitumor drugs, which relates to the field of a medicinal compound. A structural formula (I-IV) is shown as the specification, an anticancer candidate compound which has strong inhibitory activity against cancer cells and is not toxic to normal cells is currently lacked, for the reason, the method prepares 19 I-IV series compounds, and the para and meta positions of the B ring (benzene ring) introduce various alkyl groups, alkoxy groups or amino substituents or replace the B ring (benzene ring) with various heterocyclic rings. In the I-series compound, when the para position of the B ring (benzene ring) is substituted with an ethyl group, an isopropyl group, a dimethylaminogroup or a diethylamino group, the proliferation resistance of the cancer cells is very strong, and toxicity is weak for the L-02 normal cells, a selective anticancer activity coefficient (an IC50 value ratio of L-02 normal cells to cancer cells) can even exceed 10,000, and the four compounds have the potential to be developed into safe and highly effective anticancer drugs.

To identify anticancer agents with high potency and low toxicity, a series of (Z)-styrylbenzene derivatives were synthesised and evaluated for anticancer activities using a panel of nine cancer cell lines and two noncancerous cell lines. Most derivatives exhibited significant anti-proliferative activities against five cancer cell lines, including MGC-803 and BEL-7402. (Z)-3-(p-Tolyl)-2-(3,4,5-trimethoxyphenyl)acrylonitrile (6h) showed a strong inhibitory effect on MGC-803 cells (IC50 50 50 value of 6h in L-02 cells was 10,000-fold higher than in MGC-803 cells. Compound 6h inhibited proliferation of BEL-7402 cells by arresting at the G2/M phase through up-regulation of cyclin B1 expression, down-regulation of cyclin A and D1 expression, and induction of apoptosis. In addition, 6h inhibited the migration of BEL-7402 cells and the formation of cell colonies.

Eighteen novel 2,3-diphenyl acrylonitrile derivatives bearing halogens were designed, synthesized, and evaluated for biological activity. Preliminary in vitro results indicated that the majority of the compounds with a para-substituted halogen had considerable antiproliferative activity against five human cancer cell lines, including MGC-803, AGS, and BEL-7402, with IC50 values in the range of 0.46–100?μm. No significant toxic effects on the non-cancerous human liver cell line L-02 were observed. The selective inhibitory activities against cancer cells were significantly better than that of the control lead compound CA-4 and CA-4P. Particularly, potent activities were found for the derivatives of 3-(4-halogen phenyl)-2-(3,4,5-trimethoxyphenyl)acrylonitrile, such as 5c (4-fluoro), 5f (4-bromo), 5h (4-chloro), and 5k (4-trifluoro- methyl), for AGS with IC50 values of 0.75?±?0.24, 0.68?±?0.21, 0.41?±?0.05, and 1.49?±?0.92?μm, respectively. The antiproliferative effects of 5f were attributed to cell-cycle arrest in the G2/M phase, induction of cellular apoptosis, suppression of cell migration, and inhibition of cell colony formation in AGS cells.
