Following on from ezutromid, the first-in-class benzoxazole utrophin modulator that progressed to Phase 2 clinical trials for the treatment of Duchenne muscular dystrophy, a new chemotype was designed to optimise its physicochemical and ADME profile. Herein we report the synthesis of SMT022357, a second generation utrophin modulator preclinical candidate, and an asymmetric synthesis of its constituent enantiomers. The pharmacological properties of both enantiomers were evaluated in vitro and in vivo. No significant difference in the activity or efficacy was observed between the two enantiomers; activity was found to be comparable to the racemic mixture. (C) 2019 The Authors.

In this document, Transition-Metal Acetate-Promoted Intramolecular Nitrene Insertion to Vinylogous Carbonates for Divergent Synthesis of Azirinobenzoxazoles and Benzoxazines. Quality Control of 2-(4-Fluorophenyl)acetic acid.

Synthesis and isolation of highly unstable azirinobenzoxazole and benzoxazines in a chemodivergent fashion from aryl azido vinylogous carbonates by simple change in transition metal acetate is described. Thermal or rhodium(II) acetate-mediated decomposition of these azides gave dihydroazirino benzoxazole. Their nickel(II) acetate-promoted reaction gave 4-dihydro-2H-benzoxazines, whereas copper(II) acetate led to the corresponding oxidized imine derivatives. Benzaoxazine derivative could be kinetically resolved using a proline-catalyzed Mannich reaction. The benzoxazines were rapidly elaborated to angularly fused tetracyclic systems and coumarin-fused derivatives in a one pot fashion.

Two fluorescent heterocyclic ligands were obtained by reduction of imidazo[4,5-e][2,1]benzoxazole derivatives with Fe/HCl. New fluorescent nickel(II) complexes were synthesized by coordination of Ni(II) cation with the heterocyclic ligands. The structure of the complexes was established by spectral and analytical data, Job plot, and DFT calculations. Photophysical properties of Ni(II) complexes were characterized by UVVis and fluorescence spectroscopy. The optimized geometry, spectral properties, and energy difference between the HOMO and LUMO frontier orbitals of the ligands and Ni(II) complexes were obtained by DFT calculations at the B3LYP/6-311++G(d, p) level. The calculated spectral properties are in good agreement with the experimental values. The complexes were also tested as homogeneous catalysts for the transesterification of corn oil with methanol. The structure of the obtained product was confirmed by 1H NMR analysis. The catalytic results showed that the new Ni(II) complexes can be considered as potential candidates for the development of new catalytic systems for biodiesel production.

In this work, the 4-methyl-5-thiazoleethanol (C6H9NSO) molecule was studied by using the experimental spectroscopic techniques (UV-vis in three different solvents and the Fourier transform infrared spectroscopies) and density functional theory calculations. The molecular geometric parameters, vibrational wavenumbers, high-occupied-low-occupied molecular orbitals energies, H-1 and C-13 NMR chemical shift values, molecular electrostatic potential, natural bond orbitals, and nonlinear optical properties of the 4-methyl-5-thiazoleethanol were performed by using the B3LYP, B3LYP-GD3 and HSEH1PBE levels of density functional theory with 6-311++ G(d, p) basis set. The spectral results obtained from the quantum chemical calculations of 4-methyl-5-thiazoleethanol are in a good agreement with the experimental results.

A new cuprous coordination polymer (CP) with 2,2-(1,4-butanediyl)bis-1,3-benzoxazole (BBO) and triphenylphosphine sulfide (SPPh3) ligands, {[Cu(BBO)(SPPh3)]ClO4}(n) (1), has been characterized by elemental analysis, UV-Vis, infrared spectra and single-crystal X-ray diffraction. The structural analysis revealed that 1 exhibits a one-dimensional CP and is in a three-coordinate slightly distorted trigonal planar environment in which the total angle around the copper(I) atom is 359.2 degrees. Solid luminescence properties investigation showed that 1 had one emission peak at 428 nm (lambda(ex) = 355 nm, blue luminescence), which may be attributed to MLCT [(d(10)(Cu)->pi*]. The cyclic voltammogram of 1 represents irreversible Cu2+/Cu+ pairs. The antioxidant activity experiment shows that 1 has the potential ability to scavenge hydroxyl and superoxide radical in vitro studies. [GRAPHICS] .

The presence of benzoxazole moiety in most of the heterocyclic compounds is well reported. The present literature review mainly highlights the novel synthetic transformation and describes the biological potential of most of the heterocyclic compounds by virtue of presence of benzoxazole framework. Most of the researchers have revealed that benzoxazole derivatives exhibit significant antibacterial, anti-inflammatory, antifungal, anticancer, analgesic, antiviral, anti-tubercular, and anthelmintic activities. Benzoxazole moieties also act as tyrosinase inhibitor and cholesterol ester transfer protein inhibitor. This literature review may provide an opportunity to the chemists to design new derivatives of benzoxazole that proved to be the successful agent in view of safety, effectiveness, and efficacy.

As the most studied and widely used chiral ligands, C4F9I have been rapidly developed in recent decades due to their simple synthesis, easy modification, and the ability to achieve excellent results in multiple reactions. Safety of Perfluorobutyliodide.

Tuberculosis (TB) is one of the major contagious diseases with high mortality which is caused by Mycobacterium tuberculosis (Mtb) pathogen. Due to the existing antibiotic resistance (MDR-TB) to tuberculosis, the demand for the development of new potential chemotherapy drugs is increasing. Herein, we report synthesis of two novel benzoxazole-based series, namely 2-phenyl benzoxazole sulfonamide and 2-piperidine-benzoxazole sulfonamides. These compounds were evaluated for their antimycobacterial activity against Mycobacterium tuberculosis H37Rv strain, using the microplate alamarBlue assay. Molecular docking studies were carried out to comprehend the binding mode of the compounds. It is evident from molecular docking studies and minimum inhibitory concentration assay (MIC) that 2-phenyl benzoxazole sulfonamide scaffold has a greater potential of antitubercular activity possibly by ENR inhibition (inhA inhibitors). In silico cytotoxicity studies using CLC-Pred tool database suggested that both the series were relatively safe. [GRAPHICS]

Monoazo colorants with separate inbuilt ESIPT core were selected to examine the influence of azo group para to the hydroxyl group of ESIPT core and their effect on their spectral properties. They displayed absorption maxima in the visible region around 480-493 nm. 6a exhibited a broad peak along with a bathochromic shift of 40/90 nm in the solvents DMF and DMSO due to the existence of tautomeric equilibrium. They are sensitive to basic pH with a bathochromic shift of 30 nm. They are emissive in the deep red region (565-640 nm) accompanied by a Stokes shift of 62-121 nm in DMF and DMSO. More interestingly, they showed viscosity sensitive enhancement in emission in DMF: PEG 400 system in the deep red region. 6(a-c) exhibit higher quantum yield in viscous solvent i.e. 99% PEG 400 compared to that of DMF. 6a and 6c show viscosity sensitive (x) value of 0.522 and 0.513 respectively. The enhancement of emission intensity in the viscous solvent is due to charge transfer which was elucidated by polarity plots i.e. Lippert-Malaga, Mac-Rae, Weller’s and Rettig’s plots. DFT and TDDFT methods were used to correlate the experimental findings.

Therefore, highly desirable that these risks are identified and discharged early on to avoid potential scale-up issues about 112704-79-7. SDS of cas: 112704-79-7.
