Abstract

The invention which belongs to the technical field of medicines concretely relates to tricyclic dual PI3K and mTOR inhibitors with a general formula represented by formula (I), pharmaceutically acceptable salts thereof, or stereoisomers thereof. In the formula (I), R<1>, R<2>, R<3>, R<4>, R<5>, R<6>, X, A, and B are defined in the specification. The invention also relates to a preparation method of above compounds, a medicinal preparation containing the compounds, and an application of the compounds in the preparation of medicines for treating and/or preventing proliferative diseases responding to the inhibition of the activity of lipase and/or PI3-kinase-related protein kinase, especially the PI3 kinase and/or mTOR.

Description

1. Technical field [0001] The invention belongs to the field of medical technology, and specifically relates to a tricyclic PI3K and mTOR dual inhibitor, a pharmaceutically acceptable salt or a stereoisomer thereof, a preparation method of these compounds, a pharmaceutical preparation containing these compounds, and these compounds Use in the preparation of a medicament for the treatment and / or prevention of proliferative diseases responsive to inhibition of lipase and / or PI3-kinase-related protein kinases, especially PI3 kinase and / or mTOR activity. 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 c...
