Information

PIK3CA

ATP competitive

10 nM - 1 uM

Probe Availability:

In Vitro Validations

Uniprot ID: P42336

Target Class: Lipid kinase

Target SubClass: Class I

Potency: IC50

Potency Value: 5 nM

Potency Assay: In vitro kinase assay

PDB ID for probe-target interaction (3D structure): 4JPS

Structure-activity relationship: Attaching a (S)-pyrrolidine carboxamide moiety to the 2-amino group through an urea linkage confers selectivity for the alpha isoform.
