5%DMSO 40%PEG300 5%Tween80 50%ddH2O
4.05mg/ml Taking the 1 mL working solution as an example, add 50 μL of 81 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify it; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Inavolisib (GDC-0077, RG6114, RO-7113755) is a potent selective inhibitor of PI3K alpha (PI3Kα) with an IC50 of 0.038 nM. GDC-0077 is >300-fold more selective for PI3K alpha over the other class I PI3K isoforms (beta, delta, and gamma) and >2000-fold more selective over PIK family members. GDC-0077 binds to the ATP binding site of PI3K and inhibits the phosphorylation of PIP2 to PIP3.
Targets
PI3K alpha [1]
(Cell-free assay)
0.038 nM
In vitro

GDC-0077 potently inhibits mutant PI3K pathway signaling and cell viability through unique HER2-dependent mutant p110a degradation.[2]
In vivo

GDC-0077 treatment at the MTD in vivo results in tumor regressions in multiple PIK3CA-mutant xenograft and patient-derived xenograft models.[2]
