Abstract

The invention relates to an emodin quaternary phosphonium salt derivative with antitumor activity, a synthesis method therefor and an application of the emodin quaternary phosphonium salt derivative. The emodin quaternary phosphonium salt derivative is {10-[(4,5-dihydroxyl-7-methyl-9,10-anthraquinon-2-yl)oxo]decyl}phosphonium triphenylbromide. Proven by experiments, the emodin quaternary phosphonium salt derivative plays a certain role in inhibiting leukemia cells and solid tumor cells and can be used for preparing antitumor drugs. The emodin quaternary phosphonium salt derivative with antitumor activity, the synthesis method therefor and the application of the emodin quaternary phosphonium salt derivative have the following advantages that the synthesis method for the emodin quaternary phosphonium salt derivative, disclosed by the invention, is simple and is moderate in conditions; shown by the experiments, the emodin quaternary phosphonium salt derivative plays a certain role in inhibiting tumor cells, particularly HL-60 cells, Molt-4 cells, human chronic medullary system leukemia cell line K-562 cells, PANC-1 cells, Bax-PC3 cells, human liver cancer cells HepG2 and human lung cancer cells A549; and lipophilic emodin quaternary phosphonium salts have an application prospect in becoming anticancer drugs.

Description

technical field [0001] The invention relates to the field of compound synthesis, in particular to an emodin quaternary phosphonium salt derivative with antitumor activity and its synthesis method and application. Background technique [0002] Emodin is an effective active ingredient of traditional Chinese medicine rhubarb, knotweed, etc. It has broad-spectrum anticancer activity due to its planar structure and quinone structure. It has inhibitory effects on dozens of cancer cells such as leukemia, gastric cancer, liver cancer, and pancreatic cancer. It can be called a natural anti-cancer star. However, the inhibitory activity of emodin on most cancer cells is not enough to make medicine directly (IC50 is about 30-80μM), so it is inevitable to chemically modify emodin. In the early days, someone chemically modified the 6-position of emodin and introduced a long carbon chain quaternary ammonium salt. It was found that the modification can greatly improve the anti-cancer activ...
