Biological Activity

Description PD153035 is a potent and specific inhibitor of EGFR with Ki and IC50 of 5.2 pM and 29 pM.
Targets EGFR EGFR        
IC50 5.2 pM (Ki) 29 pM        

Protocol

Cell experiment [1]:

Cell lines

A panel of cancer cell lines overexpressing various levels of EGF receptor and HER2/neu.

Preparation method

The solubility of this compound in DMSO is limited. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

0.5-2800 nM; 2 h

Applications

In EGF receptor-overexpressing cell lines, PD153035 caused a dose-dependent decrease in ligand-inducedEGF receptor phosphorylation. PD153035 only inhibited HER2/neu phosphorylation at the highest concentrations tested (1400-2800 nM). PD153035 also inhibited cell proliferation in EGF receptor-positive cell lines.

Animal experiment [2]:

Animal models

Immunodeficient nude mice xenografted with A431 human epidermoid tumors

Dosage form

i.p. dose of 80 mg/kg

Application

In immunodeficient nude mice xenografted with A431 human epidermoid tumors, PD153035 rapidly suppressed the tyrosine phosphorylation of the EGF receptor by 80-90% in the tumors. Following a single i.p. dose of 80 mg/kg, the drug levels in the plasma and tumor rose to 50 and 22 μM within 15 minutes.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

PD153035 (4-(3-Bromoanilino)-6,7-dimethoxyquinazoline) is an extremely potent epidermal growth factor receptor (EGFR) inhibitor that competitively binds at the ATP site with the half maximal inhibition concentration IC50 of 0.025 nM resulting in the inhibition of the tyrosine kinase activity of the EGFR [1].

PD153035 has been found to inhibit EGF-dependent EGFR phosphorylation in a variety of human cancer cell lines over-expressing EGFRs, which include A431, Difi, DU145, MDA-MB-468, ME180 and C4i, with IC50 of 0.22 μM, 0.3 μM, 0.4 μM, 0.68 μM, 0.95 μM and 2.5 μM respectively leading to suppression of proliferation and clonogenicity in those cell lines [2].

Besides exerting potent inhibition against EGFRs, PD153035 also inhibits the closely related HER2/neu receptor but to a lesser degree [2].
