Amino- and glycoconjugates of pyrido[4,3,2-kl]acridine. Synthesis, antitumor activity, and DNA binding
摘要:
A series of amino- and glycoconjugates of pyrido[4,3,2-kl]acridine and pyrido[4,3,2-kl]acridin-4-one have been prepared. The most active molecules, the amino conjugates 7 and 11, display a cytostatic activity against HT-29 cancer cells at micromolar concentration. This activity correlates well with a strong DNA binding. The molecules, amino or glycoconjugates, bind DNA by intercalation, the amino or glyco substituent being located in one groove. None of the molecules inhibits topoisomerase activity. (c) 2006 Elsevier Ltd. All rights reserved.
