GtoPdb Ligand ID: 12084

Synonyms: TAS-117 | TAS117
Compound class: Synthetic organic
Comment: We obtained the chemical structure for pifusertib from the WHO's proposed INN list 127 (21 July 2022). In this document it was described as a serine/ threonine kinase inhibitor and antineoplastic. This appears to match the structure for TAS-117 which is an allosteric pan-Akt Inhibitor whose structure was depicted in [2], but the absolute stereo specification has been difficult to resolve. TAS-117 inhibits Akt1, 2, and 3 with similar potencies.
