Abstract

The invention provides a high morpholine compound, a preparation method, a pharmaceutical composition and application. The general formula of the high morpholine compound or pharmaceutically acceptable salt thereof is shown as (I). The high morpholine compound provided by the invention has an obvious proliferation inhibition effect on cancer cells, especially a human prostate cancer cell line PC3, a human breast cancer cell line MCF-7, a human glioma cell U87, a human laryngeal squamous cell carcinoma cell line SNU1076 and the like, and blocks the cell cycle at the G1 phase; the phosphorylation level of key protein in a PI3K / AKT / mTOR pathway is effectively inhibited on the molecular level, and the compound has the potential of being prepared into a novel anti-tumor drug and has a good market prospect.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a homomorpholine compound, a preparation method, a pharmaceutical composition and an application. Background technique [0002] Malignant tumors are known as the "number one killer" and "incurable disease" of human beings, and they pose a great threat to the physical and mental health of all human beings. At present, the number of cancer patients is increasing year by year, and the mortality rate caused by cancer remains high, ranking second among the ten major diseases. 20% of the world's new cancer patients are in China, and 24% of cancer deaths are in China. Against this backdrop, the antineoplastic drug market is developing rapidly. [0003] Traditional anti-tumor drugs are mainly cytotoxic drugs. Because their anti-tumor mechanism is to kill cells, they also have a killing effect on normal cells, resulting in severe side effects such as bone marrow suppression...
