Solubility (25°C)* In vitro DMSO 73 mg/mL (197.71 mM)
Water Insoluble
Ethanol Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
3.0mg/ml Taking the 1 mL working solution as an example, add 50 μL 60 mg/ml clarified DMSO stock solution to 400 μL PEG300, mix evenly to clarify it; add 50 μL Tween80 to the above system, mix evenly to clarify it; then continue to add 500 μL 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 PD168393 is an irreversible EGFR inhibitor with IC50 of 0.70 nM, irreversibly alkylate Cys-773; inactive against insulin, PDGFR, FGFR and PKC.
Targets
EGFR [1]
0.70 nM
In vitro PD 168393 is docked into the ATP binding pocket of EGFR TK. PD168393 completely suppresses EGF-dependent receptor autophosphorylation in A431 cells during continuous exposure, with continous suppression even after 8 hr in compound-free medium. PD168393 inhibits heregulin-induced tyrosine phosphorylation in MDA-MB-453 cells with IC50 of 5.7 nM. PD168393 is inactive against insulin, PDGF and basic FGFR TKs as well as PKC. PD168393 inhibits EGF-mediated tyrosine phosphorylation in HS-27 human fibroblasts with IC50 of 1-6 nM but has little effect on FGF- or PDGF-mediated tyrosine phosphorylation. [1] PD168393 shows rapid and potent inhibition of Her2-induced tyrosine phosphorylation with IC50 of ~100 nM in 3T3-Her2 cells. D168393 also inhibits phosphorylation of PLCγ1/Stat1/Dok1/δ-catenin in 3T3-Her2 cells, except for Fyb. [2]
In vivo PD 168393 produces tumor growth inhibition of 115% in A431 human epidermoid carcinoma xenograft in nude mice, with 50% reduced phosphotyrosine content of EGFR. PD 168393 also shows a low plasma concentration. [1]
Features Preclinical compound used in the design of CI-1033.
