Bioactivity

• Target IC50:
  Telomerase:100 nM
• In Vivo:
  In MCF-7/WT and melphalan-resistant MCF-7/MlnR cell lines, BIBR 1532 (2.5 μM) reduced colony-forming ability and shortened telomere length by inhibiting telomerase activity, and induced sensitization to chemotherapy. In vitro, BIBR 1532 dose-dependently and non-competitively inhibited telomerase activity (IC50: 100 nM).BIBR 1532 exhibited selective cytotoxicity against T-cell juvenile lymphoblastic leukemia in a dose-dependent manner.BIBR 1532-treated cells also showed nuclear condensation and apoptotic vesicle formation. In JVM13 leukemia cell line, BIBR 1532 showed a dose-dependent antiproliferative effect (IC50: 52 μM), and similar results were observed in other leukemia cell lines, including Nalm-1, HL-60 and Jurkat. In addition, BIBR 1532 showed an antiproliferative effect (IC50: 56 μM) in AML without affecting the proliferative capacity of normal hematopoietic stem cells.

• Cell Research:
  Cells are plated as triplicates in complete RPMI 1640 medium with various concentrations of BIBR1532. After 24 to 72 hours, water-soluble tetrazolium (WST-1) is added, which is transformed into formazan by mitochondrial reductase systems. The increase in the number of viable cells results in an increase of activity of mitochondrial dehydrogenases, leading to an increase of formazan dye formed, which is quantified by ELISA reader after 2, 3, and 4 hours of incubation.
