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.

Hydroxyphenyl-azoles are among the most popular ESIPT (Excited State Intramolecular Proton Transfer) scaffolds and as such, they have been thoroughly studied. Nevertheless, some aspects regarding the interplay between the emissive properties of these fluorophores and the size of their pi-conjugated framework remain controversial. Previous studies have demonstrated that benzannulation of 2 ‘-hydroxyphenyl-oxazole at the phenol group of the molecule can lead to either red- or blue-shifted fluorescence emission, depending on the site where it occurs. In this report, benzannulation at the heterocyclic unit (the oxazole site) is analysed in order to get the whole picture. The extension of pi-conjugation does not significantly affect the ESIPT emission wavelength, but it leads instead to higher energy barriers for proton transfer in the first excited singlet state, as a consequence of dramatic changes in the charge transfer character of excitation caused by successive benzannulation. Theoretical calculations revealed an interesting connection between intramolecular charge transfer and excited-state aromaticity in the S-1 state. The theoretical approach presented herein allows the behaviour of hydroxyphenyl-oxazoles in the excited state to be rationalized and, more generally, a deeper understanding of the factors governing the ESIPT process to be obtained, a crucial point in the design of new and efficient fluorophores.

A series of N-(2-(3,4,5-trimethoxybenzy1)-benzoxazole-5-yObenzamide derivatives (3a-3n) was synthesized and evaluated for its in vitro inhibitory activity against COX-1 and COX-2. The compounds with considerable in vitro activity (IC50 < 1 mu M), were evaluated in vivo for their anti-inflammatory and ulcerogenic potential. Out of the fourteen newly synthesized compounds; 3b, 3d, 3e, 3h, 31 and 3m were found to be most potent COX-2 inhibitors in in vitro enzymatic assay with IC 50 in the range of 0.14-0.69 mu M. In vivo anti-inflammatory activity of these six compounds (3b, 3d, 3e, 3h, 31 and 3m) was assessed by carrageenan induced rat paw edema method. The compound 3b (79.54%), 31 (75.00%), 3m (72.72%) and 3d (68.18%) exhibited significant anti-inflammatory activity than standard drug ibuprofen (65.90%). Ulcerogenic activity with histopathological studies was performed, and the screened compounds demonstrated significant gastric tolerance than ibuprofen. Molecular Docking study was also performed with resolved crystal structure of COX-2 to understand the interacting mechanisms of newly synthesized inhibitors with the active site of COX-2 enzyme and the results were found to be in line with the biological evaluation studies of the compounds.

The antioxidant activity of the synthesized compounds was evaluated for their antioxidant activities, such as reducing power and ABTS (2,2 ‘-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt) radical scavenging. The results of ABTS radical scavenging activities of some of the synthesized molecules showed higher activities than standard Trolox, SC50(mu M) = 213.04 +/- 18.12. One benzoxazole-coumarin (6f), two benzoxazole-isothiocyanate (7b, 7c), and two benzoxazole-triazole (8b, 8c) derivatives showed higher activities (SC50(mu M) values, 82.07 +/- 10.34, 120.19 +/- 7.30, 104.58 +/- 10.55, 153.26 +/- 7.14, and 144.82 +/- 10.68, respectively) than standard Trolox, (SC50(mu M) = 213.04 +/- 18.12).

A series of fluorogenic heterocyclic azides were prepared and assessed as reductase substrates across a selection of Gram-negative and Gram-positive microorganisms. The majority of these azides showed similar activity profiles to nitroreductase substrates. Microorganisms that do not produce hydrogen sulfide reduced the azides, indicating reductase activity was not linked to hydrogen sulfide production.

The treatment of various 2-aminophenols with isothiocyanates afforded thioureas, which were reacted in situ with triphenylbismuth dichloride in the presence of triethylamine to give the expected N-substituted benzoxazol-2-amines in good to excellent yields. Triphenylbismuth dichloride promoted the successful cyclodesulfurization of thioureas with short reaction times under mild reaction conditions. This reaction is the first example of the synthesis of heterocyclic rings using a pentavalent organobismuth reagent. (C) 2018 Elsevier B.V. All rights reserved.

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.
