Check Digit Verification of cas no

The CAS Registry Mumber 179688-01-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,6,8 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 179688-01:
(8*1)+(7*7)+(6*9)+(5*6)+(4*8)+(3*8)+(2*0)+(1*1)=198
198 % 10 = 8
So 179688-01-8 is a valid CAS Registry Number.

Structure–activity relationship study of novel quinazoline-based 1,6-naphthyridinones as MET inhibitors with potent antitumor efficacy

Zhuo, Lin-Sheng,Wu, Feng-Xu,Wang, Ming-Shu,Xu, Hong-Chuang,Yang, Fan-Peng,Tian, Yan-Guang,Zhao, Xing-E.,Ming, Zhi-Hui,Zhu, Xiao-Lei,Hao, Ge-Fei,Huang, Wei

As a privileged scaffold, the quinazoline ring is widely used in the development of EGFR inhibitors, while few quinazoline-based MET inhibitors are reported. In our ongoing efforts to develop new MET-targeted anticancer drug candidates, a series of quinaz

Design and discovery of 4-anilinoquinazoline-urea derivatives as dual TK inhibitors of EGFR and VEGFR-2

EGFR and VEGFR-2 are involved in pathological disorders and the progression of different kinds of tumors, the combined blockade of EGFR and VEGFR signaling pathways appears to be an attractive approach to cancer therapy. In this work, a series of 4-anilinoquinazoline derivatives containing substituted diaryl urea or glycine methyl ester moiety were designed and identified as EGFR and VEGFR-2 dual inhibitors. Compounds 19i, 19j and 19l exhibited the most potent inhibitory activities against EGFR (IC50?=?1?nM, 78?nM and 51?nM, respectively) and VEGFR-2 (IC50?=?79?nM, 14?nM and 14?nM, respectively), they showed good antiproliferative activities as well. Molecular docking established the interaction of 19i with the DFG-out conformation of VEGFR-2, suggesting that they might be type II kinase inhibitors.

4-substituted anilinoquinazoline derivatives, and preparation method and application thereof

-

, (2017/01/31)

The invention discloses novel 4-substituted anilinoquinazoline derivatives or pharmaceutically acceptable salts thereof, or polymorphic substances, solvates or stereomers of the 4-substituted anilinoquinazoline derivatives, and a preparation method and application thereof. The 4-substituted anilinoquinazoline compounds have favorable inhibition activities for EGFR and VEGFR-2 in a biological test and have obvious effects in an in-vitro anti-human tumor cell proliferation activity test.
