2-or 6-(1-azidoalkyl)-5,8-dimethoxy-1,4-naphthoquinone: Synthesis, evaluation of cytotoxic activity, antitumor activity and inhibitory effect on DNA topoisomerase-I
Gh. Chae et al., 2-or 6-(1-azidoalkyl)-5,8-dimethoxy-1,4-naphthoquinone: Synthesis, evaluation of cytotoxic activity, antitumor activity and inhibitory effect on DNA topoisomerase-I, ARCH PH RES, 22(5), 1999, pp. 507-514
6-(1-azidoalkyl)-DMNQ derivatives compared to 2-(1-azidoalkyl)-DMNQ isomers
, exhibited higher cytotoxic activity against L1210 mouse leukemia cells an
d stronger inhibition of DNA topoisomerase-I (TOPO-I), suggesting involveme
nt of steric hindrance. However, similar antitumor activity against mice be
aring S-180 cell was shown by 2- and 6-(1-azidoalkyl)-DMNQ derivatives.
