Design, Synthesis, and Structure−Activity Relationships of 3-Ethynyl-1H-indazoles as Inhibitors of the Phosphatidylinositol 3-Kinase Signaling Pathway
摘要:
A new series of 3-ethynyl-1H-indazoles has been synthesized and evaluated in both biochemical and cell-based assays as potential kinase inhibitors. Interestingly, a selected group of compounds identified from this series exhibited low micromolar inhibition against critical components of the PI3K pathway, targeting PI3K, PDK1, and mTOR kinases. A combination of computational modeling and structure-activity relationship studies reveals a possible novel mode for PI3K inhibition, resulting in a PI3K alpha isoform-specific compound. Hence, by targeting the most oncogenic mutant isoform of PI3K, the compound displays antiproliferative activity both in monolayer human cancer cell cultures and in three-dimensional tumor models. Because of its favorable physicochemical, in vitro ADME and drug-like properties, we propose that this novel ATP mimetic scaffold could prove useful in deriving novel selecting and multikinase inhibitors for clinical use.
The present invention provides compounds having the general structure I, or a pharmaceutically acceptable salt thereof:
wherein X is a six-member ring selected from phenyl, pyridine, or pyrimidine; Y is H, an alkenyl, a substituted alkenyl, or alkynyl, and R is H or alkyl. Pharmaceutical compositions for treating various disorders such as cancers, the compositions including compound I are also provided.
