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.

Pd/Cu bimetallic co-catalyzed direct 2-arylation of benzoxazole with aryl chloride

An efficient Palladium/Copper bimetallic co-catalyzed direct 2-arylation of benzoxazoles with aryl chlorides is presented. The Pd(OAc)(2)/Cul/NiXantphos-based catalyst enables the installation of various aryl and heteroaryl groups in good to excellent yields (75-99%). Preliminary mechanism investigation indicates that Pd/Nixantphos complex activates C-Cl bond of aryl chlorides via oxidative addition, and Cu/Nixantphos complex chelates with nitrogen atom to lower the pK(a) of the 2-H in benzoxazoles.

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.

The Bioequivalence of Tafamidis 61-mg Free Acid Capsules and Tafamidis Meglumine 4 x 20-mg Capsules in Healthy Volunteers

Tafamidis, a non-nonsteroidal anti-inflammatory benzoxazole derivative, acts as a transthyretin (TTR) stabilizer to slow progression of TTR amyloidosis (ATTR). Tafamidis meglumine, available as 20-mg capsules, is approved in more than 40 countries worldwide for the treatment of adults with early-stage symptomatic ATTR polyneuropathy. This agent, administered as an 80-mg, once-daily dose (4 x 20-mg capsules), is approved in the United States, Japan, Canada, and Brazil for the treatment of hereditary and wild-type ATTR cardiomyopathy in adults. An alternative single solid oral dosage formulation (tafamidis 61-mg free acid capsules) was developed and introduced for patient convenience (approved in the United States, United Arab Emirates, and European Union). In this single-center, open-label, randomized, 2-period, 2-sequence, crossover, multiple-dose phase 1 study, the rate and extent of absorption were compared between tafamidis 61-mg free acid capsules (test) and tafamidis meglumine 80-mg (4 x 20-mg) capsules (reference) after 7 days of repeated oral dosing under fasted conditions in 30 healthy volunteers. Ratios of adjusted geometric means (90%CI) for the test/reference formulations were 102.3 (98.0-106.8) for area under the concentration-time profile over the dosing interval and 94.1 (89.1-99.4) for the maximum observed concentration, satisfying prespecified bioequivalence acceptance criteria (90%CI, 80-125). Both tafamidis regimens had an acceptable safety/tolerability profile in this population.

Red Emitting Hydroxybenzazole (HBX) Based Azo Dyes: Linear and Non Linear Optical Properties, Optical Limiting, Z Scan Analysis with DFT Assessments

Herein, we report the hydroxybenzazole (HBX) containing azo dyes for linear and non-linear optical (NLO) applications. These bi-heterocyclic dyes have HBX scaffold (decorated with ESIPT core) and connected to another thiazole moietiy through azo bond. In DMF and DMSO, dyes are emissive in yellow-red region and large Stokes shift in the range of 62-121 nm were observed. Nonlinear absorptive coefficient (beta), nonlinear refractive index (n(2)), third order non-linear optical susceptibility (chi(3)) in DMSO, ethanol and methanol were calculated using simple and effective Z-scan technique having Nd: YAG laser at 532 nm wavelength. 4.46 x 10(-13) (e.s.u.) was the highest (chi(3)) was observed in DMSO among all the dyes. Optical Limiting (OL) values are in the range of 7.61-19.06 J cm(-2) in solvents. Thermo Gravimetric Analysis (TGA) supports that, these compounds are useful for numerous high-temperature practices in the construction of electronic as well as optical devices. Band gap was calculated by CV as well as by DFT in acetonitrile. The same trend was observed when these HOMO-LUMO gaps were correlated in between CV and DFT. To gain more insights into structural parameters, molecular geometries were optimized at B3LYP-6-311 + G (d,p) level of theory. Further, Molecular Electrostatic Potential (MEP), Frontier Molecular Orbitals (FMO) were presented using Density Functional Theory (DFT). Global hybrid functional (B3LYP, BHandHLYP) and range separated hybrid functionals (RSH) i.e. CAM-B3LYP, omega B97, omega B97X, and omega B97XD were used to calculate linear and NLO properties.

Prediction of circulating human metabolites of pemafibrate, a novel antidyslipidemic drug, using chimeric mice with humanized liver

Pharmacokinetics and metabolism of recently launched antidyslipidemic drug pemafibrate ((2R)-2-[3-({1,3-benzoxazol-2-yl[3-(4-methoxyphenoxy)propyl]amino}methyl)phenoxy]butanoic acid) was investigated in chimeric mice with humanized liver in the present study. The plasma unbound fractions of [C-14]pemafibrate in mice (0.0046-0.0048) were higher than those in monkeys and humans (0.0015-0.0022). In chimeric mice with humanized liver intravenously treated with pemafibrate at 1.0 mg/kg body weight, the pharmacokinetic parameters (CLtotal, V-ss and AUC(0-inf)) of unbound pemafibrate in chimeric mice with humanized liver were more similar to those reported in monkeys and humans than those in control mice. High concentrations of N-dealkylated form (M4) and benzoxazole 6-hydroxylated form (M6) of pemafibrate in plasma were observed as the main circulating metabolites in chimeric mice with humanized liver treated with pemafibrate. Moreover, the concentrations of other specified metabolites of pemafibrate were much higher in chimeric mice with humanized liver than in control mice. These results suggest that there are species differences in the pharmacokinetics of pemafibrate in vivo between mice tested and humans reported. Moreover, chimeric mice with humanized liver seem to be a beneficial animal model for further studies to predict the circulating human metabolites of pemafibrate and their pharmacokinetics.
