Discovery of Potent, Efficient, and Selective Inhibitors of Phosphoinositide 3-Kinase δ through a Deconstruction and Regrowth Approach
摘要:
A deconstruction of previously reported phosphoinositide 3-kinase delta (PI3K delta) inhibitors and subsequent regrowth led to the identification of a privileged fragment for PI3K delta, which was exploited to deliver a potent, efficient, and selective lead series with a novel binding mode observed in the PI3K delta crystal structure.
The present invention relates to compounds of Formula I, or a pharmaceutically acceptable salt thereof, that inhibit phosphoinositide 3-kinase;
methods of treating diseases or conditions, such as cancer, using the compounds; and pharmaceutical compositions containing the compounds.
The invention relates to the use of 1H-imidazo[4,5-c]quinolinone derivatives and salts thereof in the treatment of protein and/or lipid kinase dependent diseases and for the manufacture of pharmaceutical preparations for the treatment of said diseases; 1H-imidazo[4,5-c]quinolinone derivatives for use in the treatment of protein and/or lipid kinase dependent diseases; a method of treatment against said diseases, comprising administering the 1H-imidazo[4,5-c]quinolinone derivatives to a warm-blooded animal, especially a human; pharmaceutical preparations comprising an 1H-imidazo[4,5-c]quinolinone derivative, especially for the treatment of a protein and/or lipid kinase dependent disease; novel 1H-imidazo[4,5-c]quinolinone derivatives; and a process for the preparation of the novel 1H-imidazo[4,5-c]quinolinone derivatives.
