A theoretical study on excited state proton transfer in 2-(2 ‘-dihydroxyphenyl) benzoxazole

This research investigates the dynamic excited state process for a novel system 2-(2-dihydroxyphenyl) benzoxazole (DHBO) for excited state proton transfer (ESPT) process based on density functional theory (DFT) and time-dependent DFT (TDDFT) methods. Because 2 intramolecular hydrogen bonds (O-1?H2N3 and O-4?H5O6) in DHBO molecules may trigger proton transfer process in the S-1 state, we focus on these 2 hydrogen bonds. Our results show that only the O-1?H2N3 bond has obvious changes in both bond length and bond angle upon photoexcitation. Charge redistribution also confirms that hydrogen bond wire (O-1?H2N3) is the best way to achieve the ESPT process in the S-1 state. Considering the ESPT mechanism, our theoretical potential energy curves of DHBO indicate that only the excited state single-proton transfer process occurs via O-1?H2N3 rather than O-4?H5O6. We believe that our work not only clarifies the excited state dynamical behavior of DHBO but also promotes the investigations about ESPT reactions in intramolecular or intermolecular hydrogen bonded chemical systems.

Crystal structure and Hirshfeld surface analysis of 2-[(1,3-benzoxazol-2-yl)sulfanyl]-N-(2-methoxyphenyl)acetamide

In the title compound, C16H14N2O3S, the 1,3-benzoxazole ring system is essentially planar (r.m.s deviation = 0.004 angstrom) and makes a dihedral angle of 66.16 (17)degrees with the benzene ring of the methoxyphenyl group. Two intramolecular N -H center dot center dot center dot O and N -H center dot center dot center dot N hydrogen bonds occur, forming S(5) and S(7) ring motifs, respectively. In the crystal, pairs of C-H center dot center dot center dot O hydrogen bonds link the molecules into inversion dimers with R-2(2)(14) ring motifs, stacked along the b-axis direction. The inversion dimers are linked by C-H center dot center dot center dot-pi and pi-pi-stacking interactions [centroid-to-centroid distances = 3.631 (2) and 3.631 (2) angstrom], forming a three-dimensional network. Two-dimensional fingerprint plots associated with the Hirshfeld surface show that the largest contributions to the crystal packing come from H center dot center dot center dot H (39.3%), C center dot center dot center dot-H/H center dot center dot center dot C (18.0%), O center dot center dot center dot H/H center dot center dot center dot O (15.6) and S center dot center dot center dot H/H center dot center dot center dot S (10.2%) interactions.

Design, synthesis, and evaluation of anticonvulsant activities of benzoxazole derivatives containing the 1,2,4-triazolone moiety

A novel series of benzoxazole derivatives containing 1,2,4-triazolone (5a-m) was designed. These compounds were synthesized in order to screen their anticonvulsant activities by the maximal electroshock seizure (MES) model and the subcutaneous pentylenetetrazole (sc-PTZ) seizure model in mice. The rotarod test was used to evaluate their neurotoxicities. Most of the compounds showed anti-MES activities at 100 and 300 mg/kg. Compound 5f, which showed potential anticonvulsant activity in the MES model with ED50 values of 22.0 mg/kg, was considered as the most promising one in this study. It exhibited greater safety than that of carbamazepine and valproate regarding neurotoxicity. The efficacy of compound 5f in inhibiting the tonic seizures and death induced by the convulsants 3-mercaptopropionic acid and BIC was also verified. In an enzyme-linked immunosorbent assay, compound 5f and the positive drug phenytoin significantly increased the gamma-aminobutyric acid (GABA) level in the mouse brain. Further, pretreatment with an inhibitor of the GABA synthesizing enzyme dramatically raised the ED50 value of 5f in the MES model. These results confirmed that the compound 5f plays its anticonvulsive action via regulating the GABA function in the brain. Also, a docking study of the compound 5f in the benzodiazepine (BZD) binding site of the GABA(A) receptor confirmed possible binding of the compound 5f with BZD receptors.

Evaluation of 3-carbamoylpropanoic acid analogs as inhibitors of human hypoxia-inducible factor (HIF) prolyl hydroxylase domain enzymes

There is current interest in developing human hypoxia-inducible factor (HIF) prolyl hydroxylase domain (PHD) inhibitors for the treatment of anemia and other hypoxia-related diseases. 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.

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.

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.

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.

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.

Chemical and structural characterization of problematic suspended particles enriched from fluidized catalytic cracking slurry oil

Suspended particles (SPs) were separated from an FCC Slurry Oil (SLO) via centrifugation with the aid of toluene-dilution. Further solvent extraction of SPs with CS2/toluene (50 V/V%) mixed solvent would generate solvent extraction insolubles (SEINS) and solubles (SES). They were sent for a series of chemical and structural characterizations, respectively, in the hope of providing clues to address issues from sedimentation and clarification processes. It was found that SPs were composed of catalyst fragments and organic substances wrapped around them, serving as a shield. The characterizations from TEM and XPS strongly suggested that the outer surface of SEINS was sufficient in oxygen-containing sites (organic functional groups and aluminosilicate), while the outer surface of SPs was not. High oxygen content and almost same nitrogen content of SES, comparable with that of asphaltenes, were detected through XPS characterization. This rationalized the strong adsorption of SES on SEINS in the form of a tedious solvent extraction process. A new structure of SPs has thus been described on the basis of these characterizations. Design sedimentation experiments verified the SPs’ structure. Furthermore, the experiments offered a promising way for acquiring high clarification efficiency with rather low usage of sinking agent through solvent pretreatment.
