Synthesis, in vitro antimicrobial and in vivo antitumor evaluation of novel pyrimidoquinolines and its nucleoside derivatives

[摘要]：Seven series of pyrimidoquinoline derivatives have been synthesized, tetrazolo[4',3':-1,2]pyrimido[4,5-b] quinoline (3), 2-aminopyrimido[4,5-b]quinoline (4), triazolo[4',3':1,2]-pyrimidoquinoline (5a,b, 10), imidazolo[3',2':1,2]pyrimido[4,5-b]-quinoline (8a,b), 6-chloro-2-methylthiopyrimido[4,5-b]quinoline (12), acetylated nucleosides (16, 17a,b) and deacetylated nucleosides (18, 19a,b). Some of the novel pyrimidoquinoline derivatives possess highly activity toward the bacteria and fungi species. The new quinolines derivatives were evaluated for their anticancer activity toward human cancer cell lines by the National Cancer Institute (NCI). Most of them had excellent growth inhibition activity, having LD50 values in the low micromolar to nanomolar concentration range. (C) 2010 Elsevier Masson SAS. All rights reserved.
