Chemical Structure

Biological activities

CH5132799 potently and selectively inhibits PI3Kα and mTOR with IC50 values of 14 nM and 1.6 µM, respectively. The IC50 values of CH5132799 are 120, 500, and 36 nM against PI3Kβ, PI3Kδ, and PI3Kγ, respectively. No significant inhibitory activities of CH5132799 are observed against a representative panel of 26 protein kinases, including RTKs, nonreceptor tyrosine kinases, and serine/threonine kinases. In vitro, CH5132799 shows strong antiproliferative activity against breast, ovarian, prostate, and endo-metrial cancer cells in which the PI3K pathway is often activated. In vitro, cancer cell lines harboring PIK3CA mutations are significantly sensitive to CH5132799.[1] In human tumor cell lines with PI3K pathway activation, CH5132799 shows potent antiproliferative activity. CH5132799 is orally available. and CH5132799 has significant antitumor activity in PI3K pathway-activated human cancer xenograft models in mice.[2] In vivo, CH5132799 administrations also have potent antitumor activity in xenograft models with PIK3CA mutations.[1]
