title: [Structure-activity relationship analysis].
abstract: All samples for anticancer drug screening were classified according to their structural features and their structure-activity relationships were analyzed. Synthetic gymnastatin analogs including JCI: 11788 and JCI: 11786 altered their selectivity for protein kinase inhibition with the length of a fatty acid chain. Although a new inhibitor of tubulin depolymerization, JCI: 11578, displayed a high correlation to known tubulin binders, novel inhibitors of tubulin polymerization, JCI: 11534, JCI: 11675 and JCI: 11676, exhibited poor correlations to tubulin binders. JCI: 11403 and JCI: 11407 inhibited topoisomerase I selectively and appear to belong to a new family of topoisomerase inhibitors. They are expected to be important key compounds for structure-activity relationship analysis as well as new lead compounds for anticancer drugs.
