NCIt definition : A derivative of rhodacyanine with potential antineoplastic activity. FJ5002 inhibits
telomerase by interfering with holoenzyme assembly and telomere interaction, thus
leading to replication-dependent shortening of telomeres with a concurrent increase
in aneuploid metaphases and apoptotic cells. Telomerase is active in most tumors cells,
but is quiescent in adjacent normal cells. (NCI04);
