  Synthesis and Anti‐Proliferation Activity Evaluation of Novel 2‐Chloroquinazoline as Potential EGFR‐TK Inhibitors

  摘要：

  AbstractA novel series of 2‐chloroquinazoline derivatives had been synthesized and their anti‐proliferation activities against the four EGFR high‐expressing cells A549, NCI‐H1975, AGS and HepG2 cell lines were evaluated. The preliminary SAR study of the scaffold of new compounds showed that the compounds with a chlorine substituent on R3 had a better anti‐proliferation activity than those substituted by hydrogen atom or vinyl group. Among them, 2‐chloro‐N‐[2‐chloro‐4‐(3‐chloro‐4‐fluoroanilino)quinazolin‐6‐yl]acetamide (10b) had the best activity, and the corresponding IC50 were 3.68, 10.06, 1.73 and 2.04 μM, respectively. And compound 10b had better or equivalent activity against four cell lines than Gefitinib. The activity of the compound 10b on the EGFR enzyme was subsequently tested. The Wound Healing of A549, AGS and HepG2 cells by this compound showed that the compound can inhibit the migration of cancer cells. Finally, the action channel of the compound 10b was supported by western blotting experiments. It provides useful information for the design of EGFR‐TK inhibitors.

  N4)-aryl-N4(and N2)-[(dialkylamino)alkyl]-2,4-quinazolinediamines has been synthesized for antimalarial evaluation. Condensation of the appropriate 2,4-dichloroquinazoline (IV) with the requisite N,N-dialkylalkylenediamine afforded a series of 2-chloro-N-[(dialkylamino)alkyl]-4-quinazolinamines (V) which were condensed with the appropriate arylamine to provide the corresponding N2-aryl-N4-[(dialkylamino)alkyl]-2
