Identification of the 2-Benzoxazol-2-yl-phenol Scaffold as New Hit for JMJD3 Inhibition

JMJD3 is a member of the KDM6 subfamily and catalyzes the demethylation of lysine 27 on histone H3 (H3K27). This protein was identified as a useful tool in understanding the role of epigenetics in inflammatory conditions and in cancer as well. Guided by a virtual fragment screening approach, we identified the benzoxazole scaffold as a new hit suitable for the development of tighter JMJD3 inhibitors. Compounds were synthesized by a microwave-assisted one-pot reaction under catalyst and solvent-free conditions. Among these, compound 8 presented the highest inhibitory activity (IC50 = 1.22 0.22 /./M) in accordance with molecular modeling calculations. Moreover, 8 induced the cycle arrest in S-phase on A375 melanoma cells.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 348-54-9 is helpful to your research. Product Details of 348-54-9.

Heteroatom substitution effect on electronic structures, photophysical properties, and excited-state intramolecular proton transfer processes of 3-hydroxyflavone and its analogues: A TD-DFT study

The effects of the electron-donating capacity altered by heteroatom substituents on the electronic structures, photophysical properties, and excited-state intramolecular proton transfer (ESIPT) processes of 3HX analogues (3HF, 3HQ, 3HTF, and 3HSO where X=O, NH, S, and SO2, respectively) have been investigated by both static calculations and dynamic simulations using density functional theory (DFT) and time-dependent DFT (TD-DFT) methods at B3LYP/TZVP level for ground state (S-0) and excited-state (S-1), respectively. The static results indicate that the intramolecular hydrogen bonds of all molecules are strengthened in the S-1 state, confirmed by the red-shift of IR vibrational spectra and the topology analysis. Heteroatom substitutions cause the red-shift on enol absorption and keto emission spectra of 3HX with relatively larger Stoke shift corresponding to their HOMO-LUMO gaps compared with that of 3HF. Frontier molecular orbitals (MOs) show that upon the photoexcitation, the charge redistribution between the proton donor and proton acceptor groups have induced the ESIPT process. Moreover, the potential energy curves (PECs) of proton transfer (PT) processes of all molecules reveal that the PT processes of all molecules are most likely to proceed in the Si state because of low barrier and exothermic reaction. The chance of ESIPT for all molecules is in this order: 3HSO > 3HTF > 3HF > 3HQ. The results of dynamic simulations confirm that the ESIPT processes of all molecules easily occur with the ultrafast time scale (48, 55, 60, 70 fs for 3HSO, 3HTF, 3HF, and 3HQ respectively). Furthermore, the PT time is anti-correlated with the electronegativity of heteroatoms in 3HX, supported by Mulliken analysis. The ESIPT process of 3HSO is the fastest among 3HX in accordance with its highest intramolecular hydrogen bond strength, lowest PT barrier, and highest exothermic reaction. Nevertheless, after the ESIPT is complete, the twisted structure of 3HSO has initiated the conical intersection, leading to no keto emission observed in the experiment. (C) 2019 Elsevier B.V.

Tunable Luminescent Properties of Tricyanoosmium Nitrido Complexes Bearing a Chelating O boolean AND N Ligand

We have recently reported a strongly luminescent osmium(VI) nitrido complex [Os-VI(N)(NO2-L)(CN)(3)](-) [HNO2-L = 2-(2-hydroxy-5-nitrophenyl)benzoxazole]. The excited state of this complex readily activates the strong C-H bonds of alkanes and arenes (Commun. Chem. 2019, 2, 40). In this work, we attempted to tune the excited-state properties of this complex by introducing various substituents on the bidentate L ligand. The series of nitrido complexes were characterized by IR, UV/vis, H-1 NMR, and electrospray ionization mass spectrometry. The molecular structures of five of the nitrido compounds have been determined by X-ray crystallography. The photophysical and electrochemical properties of these complexes have been investigated. The luminescence of these nitrido complexes in the solid state, in a CH2Cl2 solution, and in a CH2Cl2 solid matrix at 77 K glassy medium clearly shows that these emissions are due to (LML)-L-3’CT [L ligand to Os (math)N] phosphorescence. The presence of strongly electron-withdrawing substituents in these complexes enhances the LML’CT emission. Our result demonstrates that the excited-state properties of this novel class of luminescent osmium(VI) nitrido complexes can be fine-tuned by introducing various substituents on the bidentate L ligand.

Coordination Assisted Distal C-H Alkylation of Fused Heterocycles

Distal C-H bond functionalization of heterocycles remained extremely challenging with covalently attached directing groups (DG). Lack of proper site for DG attachment and inherent catalyst poisoning by heterocycles demand alternate routes for site selective functionalization of their distal C-H bonds. Utilizing non-productive coordinating property to hold the heterocycle into the cavity of a template system in a host-guest manner, we report distal C-H alkylation (C-5 of quinoline and thiazole, C-7 of benzothiazole and benzoxazole) of heterocycles. Upon complexation with heterocyclic substrate, nitrile DG in template directs the metal catalyst towards close vicinity of the specific distal C-H bond of the heterocycles. Our hypothesized pathway has been supported by various X-ray crystallographically characterized intermediates.

Novel high-performance poly(benzoxazole-co-imide) resins with low dielectric constants and superior thermal stabilities derived from thermal rearrangement of ortho-hydroxy polyimide oligomers

Unsatisfied dielectric property and insufficient thermal stability are major obstacles for the commercialization of polyimide resins in the future ultralarge scale integration (ULSI) or radar-wave-transparent composite applications. The incorporation of ortho-hydroxy diamine into a common phenylethynyl terminated oligoimides, aiming to subsequently form additional rigid benzoxazole units by the thermal rearrangement (TR), were prepared. The effects of TR-able codiamine on the processing ability of oligoimides, molecular packing and properties, including thermal stability, dielectric property and bonding ability to reinforcing fibers, for the resulting poly(imide-co-benzoxazole) (PI-co-PBOs) resins have been examined in detail. These thermally rearranged PI-co-PBO resins exhibit reduced dielectric constants of 2.56-3.4 at f = 0.1 GHz, lower than the cured PI with a dielectric constant of 3.55. Meanwhile, the 5 wt% weight loss temperature (T-d5) of the resultant resins increases from 455 degrees C for the cured PI to 491 degrees C for the PI-co-PBO-60 containing 60 mol% benzoxazole unit, and correspondingly, the tensile modulus of PI-co-PBO-60 reaches 2.47 GPa, which is 76% higher than that of the cured PI. These resultant PI-co-PBOs exhibit the combined excellent properties, indicating them a great potentials as the new low-dielectric constant polymer resins in microelectronic industries or advanced composites.

A new cuprous coordinating polymer constructed by bridging 2,2-(1,4-butanediyl)bis-1,3-benzoxazole ligand: synthesis, structure, and properties

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] .
