摘要

Quantitative structure activity relationship (QSAR) study of antiproliferative activities of N-(7-indolyl)benzenesulfonamides with electrotopological state atom (ETSA) index corroborates the conclusions of the previously reported Hansch analysis that the structural requirements for interactions with receptors of human KB nasopharynx cell line are different from that for murine colon 38 and P388 leukemia cell lines. The study suggests that both phenyl ring and indole moiety are the important receptor interaction sites present on the ligands for the murine cell lines, while the latter site does not appear to play significant role in case of human KB cell carcinoma.
