Abstract

The invention belongs to the technical field of medicines, and particularly relates to an imidazo quinoline PI3K and mTOR (mammalian target of rapamycin) dual inhibitor disclosed in a general formula (I) and clinically-acceptable salt or stereoisomer thereof, wherein R1, R2, R3, R3', R4, R4', R5 and X are defined as in a specification. The invention also relates to a preparation method of the compounds, a medicine preparation containing the compounds and the application of the compounds in preparing medicines capable of treating and/ or preventing proliferative diseases.

Description

1. Technical field [0001] The invention belongs to the field of medical technology, and in particular relates to imidazoquinoline PI3K and mTOR dual inhibitors, pharmaceutically acceptable salts or stereoisomers thereof, preparation methods of these compounds, pharmaceutical preparations containing these compounds, and these Application of the compound in the preparation of medicines for treating and / or preventing proliferative diseases. 2. Background technology [0002] Tumor is a new organism formed by the body under the action of various tumorigenic factors, causing changes in the genetic material of cells, resulting in abnormal gene expression and abnormal proliferation of cells. Tumor cells lose their normal growth regulation function and have the ability to grow independently or relatively independently. When the tumorigenic factors are stopped, they can continue to grow and consume a large amount of nutrients in the human body. If not found and treated in time, cance...
