1453211-57-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1453211-57-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,3,2,1 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1453211-57:
(9*1)+(8*4)+(7*5)+(6*3)+(5*2)+(4*1)+(3*1)+(2*5)+(1*7)=128
128 % 10 = 8
So 1453211-57-8 is a valid CAS Registry Number.

Fibroblast growth factor receptor 3 (FGFR3) is an attractive therapeutic target for the treatment of patients with bladder cancer harboring genetic alterations in FGFR3. We identified pyrimidine derivative 20b, which induced tumor regression following ora

A series of 2-aminopyrimidine derivatives were designed and synthesized as highly selective FGFR4 inhibitors. One of the most promising compounds 2n tightly bound FGFR4 with a Kd value of 3.3 nM and potently inhibited its enzymatic activity with an IC50 value of 2.6 nM, but completely spared FGFR1/2/3. The compound selectively suppressed proliferation of breast cancer cells harboring dysregulated FGFR4 signaling with an IC50 value of 0.38 μM. Furthermore, 2n exhibited extraordinary target specificity in a Kinome-wide screen against 468 kinases, with S(35) and S(10) selectivity scores of 0.01 and 0.007 at 1.0 μM, respectively.

NITROGEN-CONTAINING AROMATIC HETEROCYCLIC COMPOUND

-

Paragraph 0270, (2014/05/25)

Provided is a compound useful as a prophylactic and/or therapeutic agent for bladder cancer. As a result of studies on compounds having FGFR inhibitory action, the present inventors have found that the nitrogen-containing aromatic heterocyclic compounds of the present invention have inhibitory action on FGFR1, FGFR2, and/or FGFR3, particularly, mutant FGFR3, and thus, the present invention has been accomplished. The nitrogen-containing aromatic heterocyclic compound of the present invention can be used as a therapeutic agent for various cancers related to FGFR1, FGFR2, and/or FGFR3, such as lung cancer and hormone therapy-resistant breast cancer, stomach cancer, triple negative breast cancer, endometrial cancer, bladder cancer, and glioblastoma, particularly as a prophylactic and/or therapeutic agent for mutant FGFR3-positive bladder cancer.
