| Outline of Final Research Achievements |
A new class of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) effective against the drug-resistant EGFR mutants has been developed via structural modification of the marine natural product lamellarin N and its lactam congener azalamellain N. Thus, the designed analogues possessing water-solubilizing aminoalkyl group(s) at the A-ring of their pentacyclic lamellarin core exhibited potent inhibitory activity against the gefitinib-resistant EGFR(L858R/T790M) double mutant in enzyme assay. Moreover, these compounds effectively suppressed proliferation of Ba/F3 cells, which were transduced with the osimertinib-resistant EGFR(L858R/T790M/C797S) triple mutant, in EGFR-dependent manner.
