Protein binding affinity of biologically active thiourea based half-sandwich Ru(II) cymene complexes

Experimental and DFT studies of sulfadiazine ‘piano-stool’ Ru(ii) and Rh(iii) complexes

Binding of certain metal complexes to proteins may cause cytotoxicity. While [(η⁶-p-Cym)Ru(L^SZ)₂] decomposed during the reaction with hen white egg lysozyme, a Rh(iii) analogue was covalently bio-conjugatedviathe elimination of a sulfadiazine.

Antimicrobial properties of half-sandwich Ir(iii) cyclopentadienyl complexes with pyridylbenzimidazole ligands

Ethyl group determined the toxicity of pyridylbenzimidazole Ir(iii) compounds and exchange of the group with sulfonate led to diminishing of the antibacterial activity. Increasing the metal content per complex, 3, gave rise to a compound with no toxicity.
