A DUAL SELECTIVE PI3K DELTA AND GAMMA INHIBITORS AND/OR A SALT-INDUCIBLE KINASE 3 INHIBITOR FOR TREATING SOLID TUMORS

Abstract

The present invention relates to the use of a dual selective PI3K delta and gamma (PI3K d/?) inhibitor, a Salt-Inducible Kinase 3 (SIK3) inhibitor, or a combination thereof, and pharmaceutical compositions containing them for the treatment of solid tumors, such as breast cancer. The present invention also relates to a compound of formula (A) (also known as Tenalisib, (S)-2-(1-(9H-purin-6-ylamino)propyl)-3-(3-fluorophenyl)-4H-chromen-4-one), a dual selective PI3K delta and gamma (PI3K d/?) inhibitor, or a pharmaceutically acceptable salt thereof, or a compound of formula (M) ((S)-3-(3-fluorophenyl)-2-(1-((8-hydroxy-9H-purin-6- yl)amino)propyl)-4H-chromen-4-one), a Salt-Inducible Kinase 3 (SIK3) inhibitor, or a pharmaceutically acceptable salt thereof, or a combination thereof, for the treatment of solid tumors, e.g., breast cancer.
