Methods and compositions for treating cancer and other diseases in which inhibition of telomerase activity can ameliorate disease symptoms or prevent or treat the disease relate to compounds that are derivatives of benzo\x9bb!thiophenes. Such compounds are characterized by the following structure: ##STR1## In this compound, R.sub.1 is selected from the group consisting of --OR.sub.7, --NR.sub.8 R.sub.9, --NHNR.sub.10 R.sub.11, --NHNHC(X.sub.2)NHR.sub.12, --NHSO.sub.2 NR.sub.8 R.sub.9, --NHNHC(O)R.sub.12, --NHNHSO.sub.2 R.sub.12 and --NHC(O)NR.sub.8 R.sub.9. R.sub.7 -R.sub.12 are selected independently from the group consisting of hydrogen, alkyl, aryl, aralkyl, heteroaryl and heteroaralkyl. X.sub.1 and X.sub.2 are selected independently from the group consisting of oxygen and sulfur. R.sub.2 is hydrogen or halogen. R.sub.3 -R.sub.6 are selected independently from the group consisting of hydrogen, halogen, hydroxyl, --NR.sub.8 R.sub.9, nitro, cyano, alkoxyl, lower alkyl, aryl and aryloxyl.
