[Influence of acemetacin on DNA repair and DNA synthesis in vitro and in vivo (author's transl)].

The effects of [1-(p-chlorobenzoyl)-5-methoxy-2-methyl-indole-3-acetoxy]-acetic acid (acemetacin, TV 1322, Rantudil) on DNA repair (unscheduled DNA synthesis) and semiconservative DNA synthesis have been investigated in vitro in mouse spleen cells and in vivo in human leukocytes. Quantitative determination of DNA repair was made possible by a computer program and additional measurement of parameters of uptake kinetics. in vitro results showed no influence on DNA synthesis and therapeutically relevant concentrations had no influence on DNA repair.
