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.
Features Preclinical compound used in the design of CI-1033.
Targets
EGFR [1]
0.70 nM
In vitro
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
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]
Animal Research Animal Models Athymic nude mice with A431 human epidermoid carcinoma
Dosages 58 mg/kg
Administration i.p.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
