Chemical Research Letters, May 2021.Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In heterogeneous catalysis, catalysts provide a surface to bind in a process of adsorption. , SDS of cas: 1240948-77-9, Introducing a new discovery about 1240948-77-9, Name is 5-(2-Fluorophenyl)-1H-pyrrole-3-carbonitrile, molecular formula is C11H7FN2, belongs to pyrrolines compound.

Multicolor Activatable Raman Probes for Simultaneous Detection of Plural Enzyme Activities
Raman probes based on alkyne or nitrite tags hold promise for highly multiplexed imaging. However, sensing of enzyme activities with Raman probes is difficult because few mechanisms are available to modulate the vibrational response. Here we present a general strategy to prepare activatable Raman probes that show enhanced Raman signals due to electronic preresonance (EPR) upon reaction with enzymes under physiological conditions. We identified a xanthene derivative bearing a nitrile group at position 9 (9CN-JCP) as a suitable scaffold dye, and synthesized four types of activatable Raman probes, which are targeted to different enzymes (three aminopeptidases and a glycosidase) and tuned to different vibrational frequencies by isotope editing of the nitrile group. We validated the activation of the Raman signals of these probes by the target enzymes and succeeded in simultaneous imaging of the four enzyme activities in live cells. Different cell lines showed different patterns of these enzyme activities.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1240948-77-9 is helpful to your research. SDS of cas: 1240948-77-9.
