Synthesis, structure, fluorescence, and electrochemical properties of a binuclear Ag(I) complex with 1,4-bis benzo[d]oxazol-2-yl)butane as a ligand

Reaction of 1,4-bis(benzo[d]oxazol-2-yl)butane (BBO) with [Ag(CH3CN)(4)(ClO4)] afforded a new binuclear silver(I) complex, with composition [Ag-2(BBO)(2)(ClO4)(2)], characterized by elemental analysis, UV/Vis and IR spectroscopy, and single-crystal X-ray diffraction. The results show that the Ag(I) complex consists of a centrosymmetric dimetallacyclic structure assembled from two Ag(I) atoms and two bridging BBO ligands. The coordination environment of silver(I) complex can be described as distorted trigonal planar, with one oxygen atom from a perchlorate anion and two nitrogen atoms from two BBO ligands. The luminescence properties of the ligand and the Ag(I) complex were studied in the solid state. The emission peaks of the Ag(I) complex are attributed to ligand-centered transitions. There is no effect of the complexation except for a partial quenching. The cyclic voltammograms of the Ag(I) complex indicated an irreversible Ag+/Ag couple.

Design, Synthesis and Biological Evaluation of 2 (((5-aryl-1,2,4-oxadiazol-3-yl)methyl)thio)benzo[d]oxazoles: New Antiinflammatory and Antioxidant Agents

The oxadiazole linked benzoxazoles derivatives were designed using scaffold hopping approach and their molecular level interactions with both isoforms of cyclooxygenases, Cyclo OXygenase-1 (COX-1) and CycloOXygenase-2 (COX-2), were carried out using docking protocols. Mini library of oxadiazole linked benzoxazoles derivatives were synthesized and tested for their COX inhibitory activity by invitro enzyme assay. The results indicated that compound 2-(((5-(2,4-dichlorophenyl)-1,2,4-oxadiazol-3-yl)methyl)thio)benzo[d]oxazole (5h), 2-(((5-(4-nitrophenyl)-1,2,4-oxadiazol-3-yl)methyl)thio)benzo[d]oxazole (5j) and 2-(((5-(4-(trifluoromethyl)phenyl)-1,2,4-oxadiazol-3-yl)methyl)thio)benzo[d]oxazole (5k) selectively inhibited COX-2 enzyme. The compound 5j exhibited strong selective COX-2 inhibition (IC50=4.83 mu M) followed by compound 5h (IC50=5.10 mu M) and 5k (IC50=6.70 mu M). The invivo anti-inflammatory activity of compound 5j was found to have better efficiency than the standard drug Ibuprofen at both 3h and 5h intervals. The significant molecular level interactions with respect to position of benzoxazole, 1,2,4-oxadiazole and substituted aryl groups in both COX-1 and COX-2 active sites were discussed.

Mechanofluorochromic Properties of an AIEE-Active 2-Phenylbenzoxazole Derivative: More than Meets the Eye?

The presence of a dicyanovinyl group on the robust 2-phenylbenzoxazole framework led to the emergence of aggregation-induced emission enhancement (AIEE) characteristics. A mechanofluorochromic (MFC) behaviour was observed. The pristine microcrystals emitted yellow-green light, which became golden yellow upon grinding, with the reverse process observed upon heating or solvent fuming. This phenomenon was accompanied by a reversible evolution of the photoluminescence quantum yields and lifetimes. These variations were attributed to the formation of different types of emissive species in the crystalline phases and in the ground material, which is a mixture of very small microcrystals and amorphous matter. Remarkably, evidence was also given for other spectroscopic effects, which depend on the size, compactness and heterogeneity of the solid samples. These effects are presumably linked to the generation of regions rich in low-energy exciton traps in polycrystalline and pressed samples, and to light reabsorption. They are enhanced by the fact that the pristine platelets exhibit self-waveguided edge emission, and they are all the more significant as the MFC effect is rather weak.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 345-92-6, in my other articles.

Converting Unstable Imine-Linked Network into Stable Aromatic Benzoxazole-Linked One via Post-oxidative Cyclization

Efficiently converting unstable linkages into stable linkages is an important objective in the chemistry of covalent organic frameworks (COFs), because it enhances stability and preserves crystallinity. Here, an unstable imine-linked COF was converted into a stable aromatic benzoxazole-linked COF (BO-COF) via post-oxidative cyclization, based on chemistry used to form fused-aromatic ladder-like rigid-rod polymers. The structure of the porous BO-COF was confirmed by transmission electron microscopy, infrared and solid-state nuclear magnetic resonance spectroscopies, powder X-ray diffraction patterns, and nitrogen adsorption-desorption isotherms. The efficient post-treatment of an unstable reversible COF converted it into a stable irreversible COF, which had significantly improved thermal and chemical stabilities as well as high crystallinity. This strategy can be universally applied for the synthesis of stable fused-aromatic COFs, expanding their practical applications.

High-throughput screens for agonists of bone morphogenetic protein (BMP) signaling identify potent benzoxazole compounds

Bone morphogenetic protein (BMP) signaling is critical in renal development and disease. In animal models of chronic kidney disease (CKD), re-activation of BMP signaling is reported to be protective by promoting renal repair and regeneration. Clinical use of recombinant BMPs, however, requires harmful doses to achieve efficacy and is costly because of BMPs’ complex synthesis. Therefore, alternative strategies are needed to harness the beneficial effects of BMP signaling in CKD. Key aspects of the BMP signaling pathway can be regulated by both extracellular and intracellular molecules. In particular, secreted proteins like noggin and chordin inhibit BMP activity, whereas kielin/chordin-like proteins (KCP) enhance it and attenuate kidney fibrosis or CKD. Clinical development of KCP, however, is precluded by its size and complexity. Therefore, we propose an alternative strategy to enhance BMP signaling by using small molecules, which are simpler to synthesize and more cost-effective. To address our objective, here we developed a small-molecule high-throughput screen (HTS) with human renal cells having an integrated luciferase construct highly responsive to BMPs. We demonstrate the activity of a potent benzoxazole compound, sb4, that rapidly stimulated BMP signaling in these cells. Activation of BMP signaling by sb4 increased the phosphorylation of key second messengers (SMAD-1/5/9) and also increased expression of direct target genes (inhibitors of DNA binding, Id1 and Id3) in canonical BMP signaling. Our results underscore the feasibility of utilizing HTS to identify compounds that mimic key downstream events of BMP signaling in renal cells and have yielded a lead BMP agonist.

We describe the synthesis of 3-carbamoylpropanoic acid derivatives and their evaluation as human PHD-2 inhibitors. MS assays indicated that derivatives with a 3-carbamoylpropanoic acids-containing benzoxazole moiety are inhibitors of PHD-2 with IC50 values of 2.24 mu M and 1.32 mu M, respectively. However, neither the acids nor their respective ethyl esters were observed to upregulate HIF-1 alpha levels in cells.

Synthesis, crystal structure, fluorescence and electrochemical properties of two Ag(I) complexes based on 2-(4 ‘-pyridyl)-benzoxazole/SPPh3 ligands

To explore the luminescence properties of silver complexes in the solid state, two Ag(I) complexes, [Ag(4-PBO)(2)(NO3)] {di[2-(4 ‘-pyridyl)-benzoxazole]silver(I) nitrate} (1) and [Ag-2(SPPh3)(4)](ClO4)(2) {[tetra(triphenylphosphine sulfide)disilver(I)] diperchlorate} (2) (4-PBO =2-(4 ‘-pyridyl)-benzoxazole, SPPh3 = triphenylphosphine sulfide), have been synthesized and characterized by elemental analysis, FT-IR and UV-Vis spectroscopy. Single-crystal X-ray diffraction revealed that 1 is three-coordinate by two nitrogen atoms from two 4-PBO ligands and an oxygen atom from the coordinated nitrate anion forming a triangular plane configuration. In 2, the SPPh3 ligands adopt a monodentate coordinated and monoatomic bridging mode to connect two Ag(I) ions, resulting in a three-coordinate symmetrical binuclear structure. In the solid state, the luminescence properties of the ligands 4-PBO, SPPh3 and their complexes were investigated. The results demonstrated that 1 results in the fluorescence quenching of aggregates due to the strong pi-pi stacking effect. The fluorescence enhancement of 2 may be attributed to the aggregation-induced emission (AIE) effect of restricted intramolecular rotations of the peripheral phenyl rings against the central core. In addition, cyclic voltammograms of 1 and 2 indicated an irreversible Ag+/Ag couple.

Synthesis and biological evaluation of novel N-aryl-omega-(benzoazol-2-yl)-sulfanylalkanamides as dual inhibitors of alpha-glucosidase and protein tyrosine phosphatase 1B

alpha-Glucosidase is known to catalyze the digestion of carbohydrates and release free glucose into the digestive tract. Protein tyrosine phosphatase 1B (PTP1B) is engaged in the dephosphorylation of the insulin receptor and regulation of insulin sensitivity. Therefore, dual antagonists by targeting both -glucosidase and PTP1B may be potential candidates for type 2 diabetes therapy. In this work, three series of novel N-aryl–(benzoazol-2-yl)-sulfanylalkanamides were synthesized and assayed for their -glucosidase and PTP1B inhibitory activities, respectively. Compound 3l, exhibiting the most effective -glucosidase inhibitory activity (IC50=10.96m (3l), IC50=51.32m (Acarbose), IC50=18.22m (Ursolic acid)) and potent PTP1B inhibitory activity (IC50=13.46m (3l), IC50=14.50m (Ursolic acid)), was identified as a novel dual inhibitor of -glucosidase and PTP1B. Furthermore, 3l is a highly selective PTP1B inhibitor because no inhibition was showed by 3l at 100m against PTP-MEG2, TCPTP, SHP2, or SHP1. Subsequent kinetic analysis revealed 3l inhibited -glucosidase in a reversible and mixed manner. Molecular docking study indicated that hydrogen bonds, van der Waals, charge interactions and Pi-cation interactions all contributed to affinity between 3l and -glucosidase/PTP1B.
