133550-35-3 Usage
Description
Protein tyrosine kinase (PTK) inhibitors are potential antiproliferative agents for diseases caused by the hyperactivity of PTKs. Tyrphostins are a class of antiproliferative, compounds that act as PTK blockers. PTK inhibitors that preferentially inhibit the epidermal growth factor (EGF) receptor kinase block EGF-dependent cell proliferation. AG-494 is an inhibitor of epidermal growth factor receptor kinase with an IC50 value of 1 μM in HT-22 cells.
Biological Activity
Potent inhibitor of epidermal growth factor receptor (EGFR) kinase (IC 50 = 0.7 μ M). Selective over ErbB2, PDGFR and insulin receptor kinase (IC 50 values are 42, 6 and > 100 μ M respectively).

Check Digit Verification of cas no
The CAS Registry Mumber 133550-35-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,5 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133550-35:
(8*1)+(7*3)+(6*3)+(5*5)+(4*5)+(3*0)+(2*3)+(1*5)=103
103 % 10 = 3
So 133550-35-3 is a valid CAS Registry Number.
