Synthesis and Biological Activities of Topoisomerase I Inhibitors, 6-Arylmethylamino Analogues of Edotecarin
The replacement of 1,3-dihydroxy-2-propylamino moiety at the N6-position of edotecarin (1) by arylmethylamino groups yielded a number of more potent topoisomerase I inhibitors with better cytotoxic (CTX) activities in vitro than edotecarin. Among them, the three most potent pyridylmethyl analogues, compounds 22g, 22m, and 23c, showed better antitumor activities against MKN-45 human stomach cancer or MX-1 human breast cancer xenografted mice than those of edotecarin. Furthermore, compounds 22m and 23c exhibited complete response against MX-1 cells implanted in mice.
