ABSTRACT:
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 characterized by the following structure: ##STR1## and its pharmaceutically acceptable salts. Z is selected from the group consisting of oxygen, sulfur, sulfone, sulfinyl and --NR--, where R selected from the group consisting of hydrogen, alkyl, aryl, and aralkyl. R.sub.1 is --Y.sub.n R.sub.6, where n is an integer between 0 and 10 and each Y.sub.n for n greater than 0 independently is methylene, methine, or quaternary carbon, and R.sub.6, for any value of n, is alkyl, aryl, heteroaryl, aralkyl, heteroaralkyl, alkylcarbonyl, arylcarbonyl, heteroalkylcarbonyl, heteroaralkylcarbonyl, aralkylcarbonyl, aminocarbonyl, alkylaminocarbonyl, arylaminocarbonyl, dialkylaminocarbonyl, diarylaminocarbonyl, arylalkylaminocarbonyl, carboxyl, alkoxycarbonyl, aryloxycarbonyl, sulfo, alkylsulfonyl, arylsulfonyl, alkylsulfinyl, or arylsulfinyl. R.sub.2 is hydrogen, alkyl, aryl, hydroxyl, alkoxyl, aryloxyl, halogen, cyano, amino, alkylamino, arylamino, dialkylamino, diarylamino, arylalkylamino, aminocarbonyl, alkylaminocarbonyl, arylaminocarbonyl, dialkylaminocarbonyl, diarylaminocarbonyl, arylalkylaminocarbonyl, alkylcarbonyloxy, arylcarbonyloxy, carboxyl, alkoxycarbonyl, aryloxycarbonyl, sulfo, alkylsulfonyl, or arylsulfonyl. R.sub.3 and R.sub.4 are selected independently from the group consisting of hydrogen, amino, alkylamino, arylamino, heterocycleamino, aralkylamino, heterocylcealkylamino, dialkylamino, diarylamino, arylalkylamino, nitro, halogen, hydroxyl, aryloxyl, alkoxyl, lower alkyl, aryl, heteroaryl, aralkyl, cyano, carboxyl, alkoxycarbonyl, aryloxycarbonyl, aralkoxycarbonyl, and heteroaralkyl. Finally, R.sub.5 is selected from the group consisting of iminyl, hydroximinyl, alkyliminyl, aryliminyl, aralkyliminyl, alkoximinyl, aryloximinyl, heterocycleiminyl, cyclic iminyl, bis(alkylthio)methyl, bis(arylthio)methyl, bis(alkoxy)methyl, bis(aryloxy)methyl, carboxaldehyde, hydroxymethyl, alkoxymethyl, aryloxymethyl, aralkoxymethyl, heterocycleoxymethyl, heterocyclealkoxymethyl, and --HC.dbd.NNHR.sub.7 where R.sub.7 is selected from the group consisting of hydrogen, alkyl, aryl, aralkyl, heterocycle, heterocyclealkyl, and --C(.dbd.X.sub.1)(X.sub.2).sub.p R.sub.8 where p is 0 or 1, X.sub.1 is oxygen or sulfur, X.sub.2 is selected from the group consisting of oxygen, sulfur, and --NR.sub.9 --, where R.sub.8 and R.sub.9 are selected independently from the group consisting of hydrogen, alkyl, aryl, aralkyl, and heterocycle.
