Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/23662903 | https://www.ncbi.nlm.nih.gov/pubmed/25172762 | https://www.biooncology.com/pipeline-molecules/taselisib.html

Taselisib (GDC-0032) is an highly selective small-molecule inhibitor of phosphatidylinositol 3-kinase (PI3K) p110-α isoform (PIK3CA). Taselisib is designed to bind to the ATP-binding pocket of PIK3CA to potentially prevent subsequent downstream signaling. Taselisib caused a strong differential growth inhibition in carcinoma cells harbored oncogenic PIK3CA mutations. In preclinical studies, taselisib induced growth inhibition in PIK3CA-mutant xenograft mouse models. Genentech (a Roche subsidiary) is developing taselib primarily for the treatment of solid tumours.
