Abstract
Neutron irradiation Of Cp2MoCl2 for 24 h afforded the radiotracer (CP2MoCl2)-Mo-99 which was characterised by UV-Vis spectroscopy and thin layer chromatography. Binding experiments with the thiol containing protein human serum albumin (HSA) or calf thymus DNA, were monitored for Mo-99 using a gamma counter. Under the conditions investigated, molar ratios of binding of 0.2:1 (Cp2MoCl2:DNA) and 9.4:1 (Cp2MoCl2:HSA) were calculated. The results are consistent with in vitro coordination studies that have shown strong preferential interaction Of Cp2MoCl2 with thiols versus other donor sites in biomolecules including DNA.
