Hydrazones are an interesting class of Schiff’s bases thanks to their antimicrobial, anticonvulsant, analgesic and anti-inflammatory properties. Ru(II)-arene complexes have been widely taken into account for their potent and selective antitumoral activity. In the present work we exploit the coordination of hydrazone ligands to half-sandwich η6-arene Ru(II) derivatives for enhancing their antibacterial and anticancer properties. As a development of our previous work on ruthenium arene fragments coordinated to 4-acyl-5- pyrazolone and β-ketoamine ligands, we report the synthesis and full characterization of novel Ru(II)-arene complexes (arene = p-cymene, benzene or hexamethylbenzene) containing new hydrazone ligands with general structure HL’. Recent results on their biological activity will be reported.

Abstract
Hydrazones are an interesting class of Schiff’s bases thanks to their antimicrobial, anticonvulsant, analgesic and anti-inflammatory properties. Ru(II)-arene complexes have been widely taken into account for their potent and selective antitumoral activity. In the present work we exploit the coordination of hydrazone ligands to half-sandwich η6-arene Ru(II) derivatives for enhancing their antibacterial and anticancer properties. As a development of our previous work on ruthenium arene fragments coordinated to 4-acyl-5- pyrazolone and β-ketoamine ligands, we report the synthesis and full characterization of novel Ru(II)-arene complexes (arene = p-cymene, benzene or hexamethylbenzene) containing new hydrazone ligands with general structure HL’. Recent results on their biological activity will be reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
