By using agarose gel electrophoresis technique, DNA cleaving activitie
s of two organometallic complexes, FcT (ferricenium trichloroacetate,
bis (trichloroacetic acid) solvate) and TDC (titanocene dichloride), w
ere tested in this paper. The results show that FcT can cause a single
strand cleavage of pBR322 DNA, but TDC can't do under the same condit
ion.
