Abstract

The invention belongs to the field of medical technology, and in particular relates to a selective phosphatidylinositol-3 kinase delta inhibitor shown in the formula (I), a salt of the selective phosphatidylinositol-3 kinase delta inhibitor, accepted in pharmacy, and a stereoisomer or a deuterated material of the selective phosphatidylinositol-3 kinase delta inhibitor, wherein X1, X2, X3, X4, Y, Z, W, R1 and R2 are defined as specification. The invention also relates to a preparation method of the compounds, medicinal preparations containing the compounds and application of the compounds in preparation of drugs for treating and/or preventing inflammatory diseases or tumors.

Description

technical field [0001] The invention belongs to the technical field of medicine, and specifically relates to a selective phosphoinositide 3-kinase delta inhibitor, a pharmaceutically acceptable salt thereof, a stereoisomer or a deuterated product thereof, and a preparation method of these compounds, which contain these compounds pharmaceutical preparations, and the use of these compounds in the preparation of medicines for treating inflammatory diseases or tumors. Background technique [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. Even if the tumorigenic factors are stopped, tumor cells can continue to grow and consume a large amount of nutrients in the human body. If not...
