An artificial CO-releasing metalloprotein built by histidine-selective metallation?
Chemical Communications Pub Date: 2015-01-30 DOI: 10.1039/C4CC10204E
Abstract
We report the design and synthesis of an aquacarbonyl Ru(II) dication cis-[Ru(CO)2(H2O)4]2+ reagent for histidine (His)-selective metallation of interleukin (IL)-8 at site 33. The artificial, non-toxic interleukin (IL)-8-RuII(CO)2 metalloprotein retained IL-8-dependent neutrophil chemotactic activity and was shown to spontaneously release CO in live cells.
