An autoxidation study of C2 substituted pyrimidine amino reductones
摘要:
Three pyrimidine derivatives (8a-c), differing from isouramil and divicine at C2, have been synthesized and their autoxidation rates measured spectrophotometrically. The autoxidation rates of all five pyrimidines (8a-c, isouramil and divicine) were correlated with sigma(+)(p) values (rho=-1.28, r(2)=0.949). (c) 2006 Published by Elsevier Ltd.

The present invention relates to a group of 1-[(E)-3-(3,4,5-trimethoxyphenyl)prop-2-enoyl]-2,3- dihydropyridin-6-one (piperlongumine) derivatives, analogs and pharmaceutically acceptable salts thereof. The present invention also relates to processes for preparing the same; a pharmaceutical composition and formulation containing a derivative of piperlogumine; and use of the derivatives and analogs for treating cancer.

constants of the reaction of •OH with these systems are of the order of (2−9) × 10^9 dm^3 mol^(-1) s^(-1) at near neutral pH. The difference in the spectral features of the intermediates at near neutral pH and at higher pH (10.4) obtained with these pyrimidines are attributed to the deprotonation of the OH adducts. The G(TMPD•+) obtained at pH ∼ 6, from the electron-transfer reactions of the oxidizing
