Abstract

The invention belongs to the medical chemistry field and particularly relates to a substituted pyrimidine type compound, a preparation method thereof and use thereof as a reference substance for the qualitative and/or quantitative analysis of relevant impurities in quality research of a raw material drug of mesylate of (S)-4-amino-6-((1-(8-chloro-4-oxo-2-phenyl-1,4-dihydroquinolin-3-yl)ethyl)amino)pyrimidine-5-cyano.

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, and specifically relates to a substituted pyrimidine compound, a preparation method thereof and its use as a reference substance in (S)-4-amino-6-((1-(8-chloro-4-oxo- 2-Phenyl-1,4-dihydroquinolin-3-yl)ethyl)amino)pyrimidine-5-cyanomethanesulfonate raw material drug quality research for the use of qualitative and / or quantitative analysis of related impurities. Background technique [0002] PI3K (phosphatidylinositol 3-kinase) is a member of a unique and conserved family of intracellular lipid kinases that phosphorylates the 3'-OH group on phosphatidylinositol. According to the different structures and phosphorylation substrates, PI3K can be divided into three types: I, II, and III. Among them, type I PI3K is the hotspot of current research. Plays an important role in immune cells (Coussens and Werb, Nature, 2002, 420, 860-867) and has therapeutic value in the treatment of various forms of ...
