175178-82-2 Usage
Description
AG-1478 (175478-82-2; base) is a potent and selective inhibitor of the EGFR kinase (IC50 = 3 nM). Inhibits proliferation of a variety human cancer cell lines.1,2 AG-1478 reduces pulmonary fibrosis in a rat model.3?Cell permeable.
Uses
Different sources of media describe the Uses of 175178-82-2 differently. You can refer to the following data:
1. Tyrphostin AG 1478 has been used as epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor to study its effect on desmoid cell mobility in boyden chamber motility assays. It has also been used to inhibit phosphorylation of c-Met by exogenous transforming growth factor α in epidermoid carcinoma cell line A431.
2. Tyrphostin AG 1478 is a potent and selective inhibitor of EGFR.
General Description
Highly potent and specific inhibitor of the epidermal growth factor (EGF) receptor tyrosine kinase (IC50 = 3 nM). Much higher concentrations are required for inhibition of the kinase activity of the closely related HER2 (neu/erb-B2) receptor (IC50 >100 μM), the platelet-derived growth factor (PDGF) receptor (IC50 >100 μM), and p210Bcr-Abl (IC50 >50 μM). Its mechanism of inhibition likely mimics that of the related compound, 4-(3-chloroanilino)quinazoline (CAQ), a competitive inhibitor with respect to ATP.

Check Digit Verification of cas no
The CAS Registry Mumber 175178-82-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,1,7 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 175178-82:
(8*1)+(7*7)+(6*5)+(5*1)+(4*7)+(3*8)+(2*8)+(1*2)=162
162 % 10 = 2
So 175178-82-2 is a valid CAS Registry Number.
