Abstract

The invention discloses aromatic ring / aromatic heterocycle-triazole-methylene-TCP derivatives, which have the structure described in general formula I: have significant biological inhibitory activity on LSD1, can be used to prepare drugs for inhibiting LSD1, and enrich the The types of TCP derivatives have laid the foundation for the development of new LSD1 inhibitors. Especially for the preparation of antitumor drugs, it has a certain degree of antitumor effect on gastric cancer cell lines (MGC‑803, SGC‑7901), breast cancer cell lines (MCF‑7), prostate cancer cell lines (PC‑3) and other tumor cell lines Inhibition of anti-tumor activity, provides a lead compound structure for anti-cancer drugs, and has a good application prospect. The present invention also provides the preparation method of the above-mentioned aromatic ring / aromatic heterocyclic-triazole-methylene-TCP derivative, with (1R, 2S)-phenylcyclopropylamine or (1R, 2S)-3,4 ‑Difluorophenylcyclopropylamine is used as a raw material, which is prepared by alkyne up-cycling and cycloaddition reaction. The preparation method is simple, and it is convenient for batch production and commercial application.

Description

technical field [0001] The invention relates to the technical field of medicinal chemistry, in particular to an aromatic ring / aromatic heterocyclic-triazole-methylene-TCP derivative and its preparation method and application. Background technique [0002] With the improvement of living standards, cancer is becoming a serious disease affecting human health, destroying families and placing a heavy burden on society. Due to the characteristics of infinite division and metastasis of cancer cells, cancer has become one of the major diseases affecting human life and health. Therefore, it is urgent and necessary to design and research new anticancer drugs and develop anticancer drugs with good effect and small side effects. In 2004, Dr. Shi Yang's research group discovered histone lysine-specific demethylase (LSD1), which was the earliest discovered histone demethylase. This major discovery confirmed that histone methylation is a reversible reaction. Since then, people began to ...
