Information
BIBR 1532 BIBR 1532 is a potent, selective, non-competitive telomerase inhibitor with IC50 of 100 nM in a cell-free assay. No inhibition of DNA and RNA polymerases, including HIV reverse transcriptase are observed at concentrations vastly exceeding the
In vitro
BIBR 1532 exhibits an non-competitive inhibitory effect on telomerase activity. In JVM13 leukemia cell line, BIBR 1532 shows an antiproliferative effect in a dose-dependent range with IC50 of 52 μM, and similar results are also observed in other leukemia cell lines including Nalm-1, HL-60, and Jurkat. In addition, BIBR 1532 results in a direct antiproliferative effect on acute myeloid leukemia (AML) with IC50 of 56 μM without affecting the proliferative capacity of normal hematopoietic progenitor cells. BIBR 1532 (2.5 μM) reduces colony-forming ability, and induces telomere length shortening as well as chemotherapeutic sensitization by inhibiting telomerase activity in MCF-7/WT and melphalan-resistant MCF-7/MlnR cell lines. In T-cell prolymphocytic leukemia (T-PLL), BIBR 1532 shows selective cytotoxic effects in a dose-dependent manner and BIBR 1532-treated cells also demonstrates nuclear condensation and formation of apoptotic bodies morphologically compatible with apoptosis. A recent study shows that combination treatment of BIBR 1532 and chemotherapeutic agents carboplatin results in a potential synergy for eliminateing ovarian cancer spheroid-forming cells in ES2, SKOV3, and TOV112D cell lines.
