326903-68-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 326903-68-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,6,9,0 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 326903-68:
(8*3)+(7*2)+(6*6)+(5*9)+(4*0)+(3*3)+(2*6)+(1*8)=148
148 % 10 = 8
So 326903-68-8 is a valid CAS Registry Number.

Design, synthesis and evaluation of azaacridine derivatives as dual-target EGFR and Src kinase inhibitors for antitumor treatment

Overexpression of EGFR is often associated with advanced stage disease and poor prognosis. In certain cancers, Src works synergistically with EGFR to promote proliferation, survival, invasion and metastasis. Development of dual-target drugs against EGFR and Src is of therapeutic advantage against these cancers. Based on molecular docking and our previous studies, we rationally designed a new series of azaacridine derivatives as potent EGFR and Src dual inhibitors. Most of the synthesized azaacridines displayed good antiproliferative activity against K562 and A549?cells. The representative compound 13b showed nM IC50 values against K562 and A549?cells, and inhibited EGFR at inhibition rate of 33.53% at 10?μM and Src at inhibition rate of 72.12% at 1?μM. Furthermore, compound 13b could inhibit the expression of EGFR, p-EGFR, Src and p-Src. Moreover, 13b efficiently inhibited the invasion of tumor cells and induced cancer cells apoptosis. Our study suggested that azaacridine scaffold can be developed as novel multi-target kinase inhibitors for cancer therapy.
