title: Inhibition of Escherichia coli DNA polymerase I catalysed DNA polymerization by trans-imidazolium-bisimidazoletetrachlororuthenate(III).
abstract: The tumor-inhibiting metal complex trans-imidazolium-bisimidazoletetrachlororuthenate(III) (ICR) reacts with DNA and inhibits template-primer properties for DNA synthesis catalysed by Escherichia coli DNA polymerase I. The reaction with DNA depends on the aging (half-life 6.8 h) of the aqueous solution containing ICR. The kinetics of the reaction with DNA are reminiscent of those for cisplatin.
