*Abstract: Carbon monoxide (CO) is a well known toxic gas, but emerging research also suggest potentially beneficial effects of temporarily increased levels of CO in attenuating deleterious effects of reactive oxygen species (ROS). To date the study and evaluation of the effects of CO have relied on detecting gross anatomical change of some observable parameter, such as infarct size in the studies of CO on ischemia/reperfusion or offline extracellular measurements using myoglobin as a colorimetric readout. These macroscopic and colorimetric outputs do not provide detailed information about cellular signaling pathways.

Scientists at UC Berkeley have designed, synthesized, and evaluation of a new type of chemical reagent for selective CO detection in living cells by exploiting palladium-mediated carbonylation chemistry. The probe is based on a cyclometallated aryl-palladium compound attached to a BODIPY –type fluorophore that will react with CO in a carbonylation reaction to produce a highly fluorescent amino acid species with concomitant loss of palladium. The probe is capable of displaying an increase in fluorescence in both cuvettes and in live cells. Carbon Monoxide Probe 1 (COP-1) represents a unique first-generation chemical tool that features a robust turn-on response to CO with selectivity over reactive nitrogen, oxygen, and sulfur species. It can be used to detect CO in aqueous buffer and in live-cell specimens, providing a potentially powerful approach for interrogating its chemistry in biological systems.
