Their dark stability establishes them as CORM prodrugs. The monomers show a faster CO-release compared to the peptide and dendrimer conjugates. However, both monomers and peptide conjugates release two equivalents of CO upon photoactivation at 365 nm. The dendrimer conjugates can deliver up to seven equivalents of CO due to the higher number of Mn(CO)3 moieties per molecular unit. In the future, the biological activity of the conjugates needs to be further explored to establish the targeted delivery of CO to cells and tissues.}, subject = {Mangankomplexe}, language = {en} }
