  Synthesis, identification and antiplatelet evaluation of 2-morpholino substituted benzoxazines

  摘要：

  A number of 2-morpholino substituted benzoxazines have been prepared in order to test their effectiveness against ADP and collagen induced platelet aggregation. The reaction of 2-thio-1,3-benzoxazines with morpholine has been generalised to enable the use of substituted benzoxazines. Two separate methods were used to prepare 7-O-2-morpholino substituted benzoxazines from 7-hydroxy-2-morpholino benzoxazines. Antiplatelet testing was carried out on 15 of the title compounds. 7-(2-Chloroethoxy)-8-methyl-2-morpholin-4-yl-4H-1,3-benzoxazin-4-one 15d and 7-[2-(4-methylpiperazin-1-yl)ethoxy]-8-methyl-2-morpholin-4-yl-4H-1,3-benzoxazin-4-one 16d showed potent activity against ADP and collagen induced platelet aggregation. The structures of the newly prepared compounds were confirmed by microanalysis as well as the analysis of IR, H-1 and C-13 NMR. (c) 2007 Elsevier Masson SAS. All rights reserved.

  A number of new 2-amino-[5, 6, 7 and 8]-O-substituted 1,3-benzoxazines, and 2-amino 8-methyl-7-O-substituted-1,3-benzoxazines were synthesized. Thirty one new compounds were tested for their effect on collagen induced platelet aggregation and it was found that the most active compounds were 8-methyl-2-morpholin-4-yl-7-(pyridin-3-ylmethoxy)-4H-1,3-benzoxazin-4-one 9f and 8-methyl-2-morpholin-4-yl-7-(pyridin-4-ylmethoxy)-4H-1,3-benzoxazin-4-one 9j with IC(50) = 2 +/- 1.5 and 4 +/- 2 mu M respectively. Inhibition of DNA-PK activity at concentrations of 1.6-4 mu M were tested for 9 products 5i, 7a-e and 9b, 9f and 9j. Crown Copyright (C) 2010 Published by Elsevier Masson SAS. All rights reserved.
