Photocatalytic oxidative coupling of amines is a promising method for imine synthesis. In this paper, a robust covalently-bonded direct Z-scheme heterostructure (PDI/mpgCN) for photocatalytic oxidative coupling of amine was reported for the first time. Perylenetetracarboxylic diimide (PDI) mols. were covalently connected to the surface of mesoporous carbon nitride (mpgCN) via an in-situ condensation strategy. Compared with the poor conversion efficiency upon pristine g-C₃N₄, PDI/mpgCN heterostructure exhibits a remarkable enhancement on amine oxidation rate (AOR), with the optimal AOR reaches to as high as 20.63 mmol g^-1 h^-1 upon 20 % PDI/mpgCN. As far as we know, it is the highest AOR achieved so far for amine photooxidation coupling with heterojunction materials.

Macrophage migration inhibitory factor (MIF) is a cytokine with key roles in inflammation and cancer, which qualifies it as a potential drug target. Apart from its cytokine activity, MIF also harbors enzyme activity for keto-enol tautomerization. MIF enzymic activity has been used for identification of MIF binding mols. that also interfere with its biol. activity. However, MIF tautomerase activity assays are troubled by irregularities, thus creating a need for alternative methods. In this study, we identified a 7-hydroxycoumarin fluorophore with high affinity for the MIF tautomerase active site (K_i = 18±1 nM) that binds with concomitant quenching of its fluorescence. This property enabled development of a novel competition-based assay format to quantify MIF binding. We also demonstrated that the 7-hydroxycoumarin fluorophore interfered with the MIF-CD74 interaction and inhibited proliferation of A549 cells. Thus, we provide a high-affinity MIF binder as a novel tool to advance MIF-oriented research.
