Mixed‐ligand complexes of technetium(V) or rhenium(V) containing tridentate N‐[(dialkylamino)(thiocarbonyl)]benzamidine (H2L1) and bidentate N,N‐dialkyl‐N′‐benzoylthiourea (HL2) ligands were formed in high yields when (NBu4)[MOCl4] (M = Tc or Re) or [ReOCl3(PPh3)2] was treated with mixtures of the proligands. Other approaches for the synthesis of the products are reactions of [MOCl(L1)] complexes with HL2 or compounds of the composition [ReOCl2(PPh3)(L2)] with H2L1. The resulting air‐stable [MO(L1)(L2)] complexes possess potential for the development of metal‐based radiopharmaceuticals. [TcO(L1)(L2)] complexes are readily reduced by PPh3 with formation of [Tc(L1)(L2)(PPh3)]. The resulting TcIII complexes undergo two almost‐reversible oxidation steps corresponding to one‐electron transfer processes.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)

Two novel families of pyrazolyl-diamine ligands that bear an anthracen-9-yl group as a DNA-binding fragment, pz*(CH2)2NH(CH2)2NHCH2-9-anthryl (pz*=pz (L(1)), 3,5-Me2pz (L2)) and pz*(CH2)2NH(CH2)2NH(2 (pz*=4-(9-anthrylmethyl)pz (L3), 3,5-Me2-4-(9-anthrylmethyl)pz (L4)), have been prepared and fully characterised. In the case of L2-L4, the evaluation of their coordination capability towards the fac-[Re(CO)3]+ core led to the synthesis of the organometallic complexes fac-[Re(CO)(3){3,5-Me(2)pz(CH2)2NH(CH2)2NHCH2-9-anthryl}]Br (7) and fac-[Re(CO)3{4-(9-anthrylmethyl)pz*(CH2)2NH(CH2)2NH2}]Br (pz*=pz (8), 3,5-Me2pz 9). The interaction of the novel pyrazole-diamine ligands and the rhenium(I) complexes with calf thymus (CT) DNA has been investigated with a variety of spectroscopic techniques (UV-visible, fluorescence, circular dichroism (CD) and linear dichroism (LD)). All of the evaluated compounds have a moderate affinity to CT DNA (3.46x10(3)

“…The discoveries of the Re(CO) 3 (H 2 O) 3 + cation 1 + and its technetium congener [1,2] sparked intense interest in recent years for their potential as reagents in aqueous organometallic chemistry. One focal point is the search for viable d 6 M(CO) 3 L + (M = 186/188 Re, 99m Tc) compounds for use as therapeutic and imaging agents, respectively, in nuclear medicine.…”
