Dual Role of Oxoaldehydes: Divergent Synthesis of 3-Aryl- and 3-Aroylcoumarins

A facile and efficient synthetic approach to various valuable 3-aryl- and 3-aroylcoumarins by the direct arylation and aroylation of coumarins with glyoxals in a metal-free manner is presented. The aryl glyoxal is for the first time recognized to serve as an aryl surrogate in addition to its role as an aroyl transfer reagent via a simple switch in reaction conditions. The approach accommodates a broad substrate scope and high yields of the two types of cross-coupling reactions starting from identical starting materials.

7-Hydroxycoumarins Are Affinity-Based Fluorescent Probes for Competitive Binding Studies of Macrophage Migration Inhibitory Factor

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 enzymatic activity has been used for identification of MIF binding molecules that also interfere with its biological 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 (Ki = 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.

Chlorophyll-catalyzed photochemical regioselective coumarin C-H arylation with diazonium salts

This communication describes the development of a mild method for the cross-coupling of the C3-position of coumarin with an array of diazonium salts mediated by chlorophyll as a biocatalyst via visible light catalysis. A natural pigment such as chlorophyll is used as a green photosensitizer and environmentally benign catalyst. This general and easy procedure provides a transition-metal-free alternative for the formation of 3-aryl coumarin derivatives at room temperature with good to excellent yields. This journal is

1,2,3,4-Tetrahydroisoquinoline/2H-chromen-2-one conjugates as nanomolar P-glycoprotein inhibitors: Molecular determinants for affinity and selectivity over multidrug resistance associated protein 1

A series of coniugates bearing a 1,2,3,4-tetrahydroisoquinoline motif linked to substituted 7-hydroxy-2H-chromen-2-ones was synthesized and assayed through calcein-AM test in Madin-Darby Canine Kidney (MDCK) cells overexpressing P-glycoprotein (P-gp) and closely related multidrug resistance associated protein 1 (MRP1) to probe the interference with efflux mechanisms mediated by P-gp and MRP1, respectively. A number of substituents at C3 and C4 of coumarin nucleus along with differently sized and shaped spacers was enrolled to investigate the effects of focused structural modifications over affinity and selectivity. Linker length and flexibility played a key role in enhancing P-gp affinity as proved by the most potent P-gp modulator (3h, IC50 = 70 nM). A phenyl ring within the spacer (3k, 3l, 3o) and bulkier groups (Br in 3r, Ph in 3u) at coumarin C3 led to derivatives showing nanomolar activity (160 nM 50 350). Molecular docking calculations carried out on a human MDR1 homology model structure contributed to gain insights into the ligands’ binding modes. Some compounds (3d, 3h, 3l, 3r, 3t, 3u) reversed MDR thereby restoring doxorubicin cytotoxicity when co-administered with the drug into MDCK-MDR1 cells.

Synthesis and biological evaluation of 3-arylcoumarin derivatives as potential anti-diabetic agents

A variety of substituted 3-arylcoumarin derivatives were synthesised through microwave radiation heating. The method has characteristics of environmental friendliness, economy, simple separation, and purification process, less by-products and high reaction yield. Those 3-arylcoumarin derivatives were screened for antioxidant, α-glucosidase inhibitory and advanced glycation end-products (AGEs) formation inhibitory. Most compounds exhibited significant antioxidant and AGEs formation inhibitory activities. Anti-diabetic activity studies showed that compounds 11 and 17 were equipotent to the standard drug glibenclamide in vivo. According to the experimental results, the target compound 35 can be used as a lead compound for the development of new anti-diabetic drugs. The whole experiment showed that anti-diabetic activity is prevalent in 3-arylcoumarins, which added a new natural skeleton to the development of anti-diabetic active drugs.
