Abstract

Provided are a class of multi-targeted inhibitors of IRAK4 and BTK, and the use thereof in preparing a drug for treating IRAK4- and BTK-related diseases. The present invention specifically relates to the compounds represented by formula (II), isomers thereof or pharmaceutically acceptable salts thereof.

Claims (35)

1 . A compound represented by formula (II) or a pharmaceutically acceptable salt thereof,

wherein,

R 1 is selected from H, F, Cl, Br, I, OH, NH 2 , CN, C 1-6 alkyl, cyclopropyl and —C(═O)—NH 2 , wherein the C 1-6 alkyl, cyclopropyl and —C(═O)—NH 2 are optionally substituted by 1, 2 or 3 R a ;

R 2 is selected from thienyl, phenyl, pyridyl, cyclopropyl, cyclohexyl and

wherein the thienyl, phenyl, pyridyl, cyclopropyl, cyclohexyl and

are optionally substituted by 1, 2, 3, 4 or 5 R b ;

T 1 is selected from CH 2 , NH and O;

R 3 is selected from C 1-6 alkyl, wherein the C 1-6 alkyl is optionally substituted by 1, 2 or 3 R c ;

R a is each independently selected from F, OH, NH 2 and CN;

R b is each independently selected from H, D, F, Cl, Br, I, OH, NH 2 , CN, C 1-3 alkyl, COOH, —C(═O)—C 1-3 alkyl, —C(═O)—O—C 1-3 alkyl and —C(═O)—NH 2 , wherein the OH, NH 2 , C 1-3 alkyl, COOH, —C(═O)—C 1-3 alkyl, —C(═O)—O—C 1-3 alkyl and —C(═O)—NH 2 are optionally substituted by 1, 2 or 3 R;

R c is each independently selected from F, OH, NH 2 , CN, CH 3 , COOH and —SO 2 CH 3 ;

R is each independently selected from F, OH, NH 2 and CH 3 .

2 . The compound as defined in claim 1 or the pharmaceutically acceptable salt thereof, wherein, R 1 is selected from H, F, Cl, Br, I, OH, NH 2 , CN, C 1-3 alkyl, cyclopropyl and —C(═O)—NH 2 , wherein the C 1-3 alkyl, cyclopropyl and —C(═O)—NH 2 are optionally substituted by 1, 2 or 3 R a .
