To improve the selectivity, delivery, and activity of ferric (Fe) anticancer agents, we design prodrugs based on N-donor residues of the humanserumalbumin (HSA) carrier IIA subdomain. We synthesized six Fe(III) compounds derived from 2-hydroxy-1-naphthaldehyde thiosemicarbazone (7–12). HSA complex structure revealed that Fe compound binds to the hydrophobic cavity in the HSA IIA subdomain. Lys199

Magnetite functionalized nanoparticles with Pd(L3)2 and Pd(L4)2 show antiproliferative activity against DU-145 and HuTu80; Pd(L2)2 is found to be a promising pharmacological agent.
New dinuclear pentacoordinate molybdenum(V) complexes, [Mo2VO3L2] [L = thiosemicarbazonato ligand: C6H4(O)CH:NN:C(S)NHR′ and C10H6(O)CH:NN:C(S)NHR′; R′ = H, CH3, C6H5) were obtained either by oxygen atom abstraction from MoVIO2L with triphenylphosphine or by using [Mo2O3(acac)4] in the reaction with the corresponding ligands H2L.

New dioxomolybdenum(VI) complexes were obtained by the reaction of [MoO2(acac)2] with 4-phenylthiosemicarbazone ligands derived from salicylaldehyde, 2-hydroxy-1-naphthaldehyde, 2-hydroxy-3-methoxybenzaldehyde or from 4-(diethylamino)salicylaldehyde. In all complexes the ligands are coordinated to molybdenum as tridentate ONS-donors through phenolic-oxygen, imine-nitrogen and thiol-sulphur. Octahedral

Synthesis of novel molybdenum(V) complexes: Structural characterization of two thiosemicarbazonato complexes [MoOCl2{C6H4(O)CH:NNHC:SNHC6H5}] and [MoOCl2{C10H6(O)CH:NNHC:SNHC6H5}]·CH3CN, and two oxohalomolybdates NH4[MoOCl4(CH3CN)] and [C5H5NH]2[MoOCl5]·CH2Cl2
Mononuclearoxomolybdenum(V) complexes with thiosemicarbazonato ligands as condensation products of aldehydes (salicylaldehyde, 2-hydroxynaphthaldehyde) with thiosemicarbazides (H2NNHC:SNHR; R = H, CH3, C6H5) were prepared.
