  Design, Synthesis, and DNA-Binding of N-Alkyl(anilino)quinazoline Derivatives

  摘要：

  New N-alkylanilinoquinazoline derivatives 5, 12, 20, and 22 have been prepared Crow 4-chloro-6, 7-dimethoxyquinazoline 3, 4-chloro-6,7-methylenedioxyquinazoline 19, and commercially available anilines. Differents classes of compounds substituted by an aryloxygroup (6a-c. 16a,b, and 17a,b). (aminophenyl)ureas (12a,b and 13a-f), anilines (4a-m, 20a,b), N-alkyl(aniline) (5a-m, 21a,b. 22a,d). and N-aminoalkyl(aniline) (22e-g) have been synthesized. These molecules were evaluated for then. cytotoxic activities and as potential DNA intercalating agents. We studied the strength and mode of binding to DNA of these molecules by DNA melting temperature measurements, fluorescence emission. and circular dichroism. The results of various spectral and gel electrophoresis techniques obtained with the different compounds, in particular compounds 5g and 22f, revealed significant DNA interaction. These experiments confirm that the N-aminoalkyl(anilino)-6,7-dimethoxyquinazoline nucleus is an efficient pharmacophore to trigger binding to DNA, via an intercalative binding process.

  produced the most potent inhibitors of Flt and KDR tyrosine kinases activity with IC(50) values in the nanomolar range (e.g. 10, 12, 13, 16, and 18). Investigation of the quinazoline C-6 and C-7 positions indicates that a large range of substituents are tolerated at C-7, whereas variation at the C-6 is more restricted. At C-7, neutral, basic, and heteroaromatic side chains led to very potent compounds, as

  We report here the design and synthesis of a series of 4-anilinoquinazoline derivatives, of which 7 compounds were crystallographically characterized, as epidermal growth factor receptor (EGFR) inhibitors by modifications on the aniline ring or at the 6-alkoxy site of the 6,7-dimethoxy-4-anilinoquinazoline pharmacophore. The relative inhibition efficiency on EGFR of all as-prepared compounds were measured and ordered, and the IC50 values of nine highly active compounds were determined by ELISA. Docking studies indicated that all 4-anilinoquinazoline derivatives could be inserted into the ATP-binding pocket of the EGFR via indirect docking, and that the modifications at the 3'-position of the anilino group and 6-alkoxy site of the quinazoline ring have little interference with the formation of the two essential H-bonds between the N3 of the quinazoline ring and Thr766 through a water molecule, and the N1 of the quinazoline ring and N-H of Met769. The displacing of the phenyl at 4-position with pyridinyl dramatically reduces the activity of the quinazoline pharmacophore, the resulting derivative (10) being the least active compound. The docking results also showed that the formation of new H-bonds between the N-H of the ethylenediamine group linked to the 6-alkoxy site and Asp776/Cys773 in the binding pocket of EGFR makes compounds 19 (IC50= 12.1 +/- 1.6 nM) and 20 (IC50 = 13.6 +/- 0.8 nM) the most potent EGFR inhibitors in this class and worthy of further modification to obtain more potent anticancer compounds.
