Biological Activity for BIBR 1532

BIBR 1532 is a selective telomerase inhibitor (IC₅₀ values are 93, > 100000 and > 100000 nM for human telomerase, human RNA polymerase I and human RNA polymerase II + III respectively). Causes telomere shortening in exponentially growing NCI-H460 lung carcinoma cells and eventual growth arrest.
