Abstract

The invention relates to 2-[4-(quinoxaline-2-oxyl)phenoxyl]fatty acyl pyridylamine as shown in the chemical structural formula II or formula II. In the formula, R and R<1> are selected from hydrogen, deuterium, C1-C2 alkyl group, C3-C4 straight chain or branched alkyl group; X<1>, X<2>, X<4>, X<5>, X<7>, X<9> and X<10> are selected from hydrogen, deuterium and C1-C2 alkyl group; X<3> is selected from nitro group; X<6> is selected from hydrogen, deuterium, C1-C2 alkyl group, fluorine, chlorine and bromine; and X<8> is selected from fluorine, chlorine and bromine. The 2-[4-(quinoxaline-2-oxyl)phenoxyl]fatty acyl pyridylamine is applied in preparation of anti-cancer drugs.

Description

technical field [0001] The present invention relates to a class of compounds and new applications thereof, in particular to the application of 2-[4-(quinoxaline-2-oxyl)phenoxy] fatty acid pyridinamine in the preparation of anticancer drugs. Background technique [0002] 4-Aryloxyphenoxyalkanoic acid derivatives have a wide range of biological activities, among which aryloxyphenoxypropionic acid derivatives are their typical representatives, and there are more than 20 commercial varieties in agricultural herbicides. At the same time, 4-aryloxyphenoxyalkanoic acid derivatives have also been widely reported in the research of anticancer drugs [Investigational New Drugs, 1999, 16:287-296; Investigational New Drugs, 1998, 16:129-139; Acta Pharmaceutica Sinica , 2005, 40(9):814-819], wherein XK469 (2-(4-(7-chloroquinoxalin-2-yloxy)phenoxy)propionic acid) is a phase I clinical trial conducted by DuPont Company of the United States. A new type of anti-tumor drug studied, XK469 has ...
