BIBR 1532 is a mixed-type non-competitive inhibitor of telomerase (IC50 = 93 nM) that has little effect on several mammalian DNA and RNA polymerases, bacterial DNA helicase, or HIV-1 reverse transcriptase. It specifically targets the telomerase reverse transcriptase catalytic subunit, TERT. Through its effects on telomerase, BIBR 1532 induces senescence or apoptosis in cancer cells. Apoptosis in triple negative breast cancer cells induced by BIBR 1532 is potentiated by glucose restriction.
