Preparation of Novel Coumarin Cyclic Polymer/Montmorillonite Based Nanocomposites

In present study, the synthesis, characterization, and thermal properties of novel coumarin cyclic polymer poly(3-benzoyl coumarin-7-yl-methacrylate) polymer/montmorillonite based nanocomposites were performed. At the characterizations of nanomaterials FT

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.

Coumarin derivatives act as novel inhibitors of human dipeptidyl peptidase III: Combined in vitro and in silico study

Dipeptidyl peptidase III (DPP III), a zinc-dependent exopeptidase, is a member of the metalloproteinase family M49 with distribution detected in almost all forms of life. Although the physiological role of human DPP III (hDPP III) is not yet fully elucida

Ros inhibitory activity and cytotoxicity evaluation of benzoyl, acetyl, alkyl ester, and sulfonate ester substituted coumarin derivatives

Background: A number of non-steroidal anti-inflammatory drugs (NSAIDs) including aspirin, indomethacin, ibuprofen, flufenamic acid, and phenylbutazone are being clinically used to treat inflammatory disorders. These NSAIDs are associated with serious side

Anti-MRSA (Multidrug resistant Staphylococcus aureus) activity of 3-substituted coumarins

Background: Infectious pathogenic bacteria are the key virulence in our daily life. Especially diseases produced by multidrug resistant Staphylococcus aureus (MRSA) still contributing in morbidity and mortality in humans. Discovery of new and safer antibi

The synthesis of coumarin derivatives using choline chloride/zinc chloride as a deep eutectic solvent

In this work, choline chloride/zinc chloride was employed as a deep eutectic solvent (DES) in the green synthesis of coumarin derivatives using Knoevenagel condensation. Coumarins are important organic structures with useful application in various fields.

KETOCOUMARINS AS PHOTOINITIATORS AND PHOTOSENSITIZERS IN INKS

A series of novel ketocoumarin photoinitiators are disclosed for use in radiation curing.

Substituted 3-benzylcoumarins as allosteric MEK1 inhibitors: Design, synthesis and biological evaluation as antiviral agents

In order to find novel antiviral agents, a series of allosteric MEK1 inhibitors were designed and synthesized. Based on docking results, multiple optimizations were made on the coumarin scaffold. Some of the derivatives showed excellent MEK1 binding affinity in the appropriate enzymatic assays and displayed obvious inhibitory effects on the ERK pathway in a cellular assay. These compounds also significantly inhibited virus (EV71) replication in HEK293 and RD cells. Several compounds showed potential as agents for the treatment of viral infective diseases, with the most potent compound 18 showing an IC 50 value of 54.57 nM in the MEK1 binding assay.

Synthesis and selective human monoamine oxidase inhibition of 3-carbonyl, 3-acyl, and 3-carboxyhydrazido coumarin derivatives

Several 3-carbonyl (1-26), 3-acyl (27-52), and 3-carboxyhydrazido (53-58) coumarins have been synthesized in high yields (72-99%) and tested in vitro for their human monoamine oxidase A and B (hMAO-A and hMAO-B) inhibitory activity. Different substituents on the coumarin nucleus were evaluated for their effect on biological activity and isoform selectivity. Substitution at position C7 of the 3-ethyl ester coumarin ring, or the introduction of a hydrazido substituent at C3, were important to obtain highly potent and selective hMAO-B inhibitors with IC50 values in the nanomolar range. Some derivatives were also submitted to a stability test and showed no chemical cleavage in vitro.

α-Glucosidase inhibitory antihyperglycemic activity of substituted chromenone derivatives

Series of 3,4- and 3,6-disubstituted chromenones including new chromenone derivatives were synthesized applying various synthetic strategies including Pechmann condensation, Knoevenagel condensation, Reimer-Tiemann reaction and Suzuki coupling in very good yields. Synthesized compounds (4a-z) were screened for in vitro α-glucosidase inhibitory and 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activities. Majority of compounds displayed varying degrees of α-glucosidase inhibitory and DPPH scavenging activity. Compound 4x emerged as the most potent α-glucosidase inhibitor in present series of compounds owing to the presence of 3-acetyl-6-(6-methoxy-3-pyridyl) group on chromenone; however, it could not display DPPH scavenging activity and was found to be mixed non-competitive type inhibitor of rat intestinal α-glucosidase. When tested in vivo for antihyperglycemic activity in starch loaded Wistar rats, it displayed significant antihyperglycemic property. This is the first report assigning rat intestinal α-glucosidase inhibitory property for this class of new chromenones and presents new family of compounds possessing α-glucosidase inhibitory activities and antihyperglycemic property. Compound 4x may serve as an interesting new compound for the development of therapeutics targeted against diet-induced hyperglycemia in diabetes.
