Alternative Approaches to the Discovery and Development of Telomerase- Targeted Anticancer Drugs

Four different approaches have been reviewed herein: i) nucleoside analogs as mock agents of the reverse transcriptase (hTERT) catalytic site, ii) miscellaneous molecules with unknown mechanism(s) of action, iii) inhibitors of upstream processes of regulation of the hTERT subunit, iiii) immunotherapy against immunogenic hTERT- derived peptides.
