Acryloyl isothiocyanate skeleton as a precursor for synthesis of some novel pyrimidine, triazole, triazepine, thiadiazolopyrimidine and acylthiourea derivatives as antioxidant agents

The reactions of 2-cyano-3-pyrazolylpropenoyl isothiocyanate derivative 2 with some mono- and bidentate nucleophiles namely, dodecan-1-amine, 6-aminothiouracil, hydrazine, phenylhydrazine, phenylurea, semicarbazide, and thiosemicarbazide, in addition to some derivatives of hydrazides, have been investigated to obtain some valuable heterocyclic skeletons gathering with a pyrazole core, viz. pyrimidine, triazole, triazepine, thiadiazolopyrimidine as well as acylthiourea derivatives. Hydrazinolysis of 2 was found to provide a mixture of thiosemicarbazide, diheterylazine, and triazepine derivatives. Treatment of 2 with phenylhydrazine was mainly dependent on the reaction conditions to produce a mixture of pyrimidinethione and triazole derivatives at room temperature or the triazepine derivative at heating conditions. The antioxidant activity screening of these compounds disclosed that pyrimidinethione derivatives 9 and 13 exhibited the most potency.

Synthesis, structure and fluorescent sensing for nitrobenzene of a Zn-based MOF

Nitrobenzene (NB) can cause serious harm to ecosystems and human health. In order to identify and detect NB effectively, a micro-porous Zn-based metal-organic framework (Zn-MOF) material was prepared. Zn-MOF material named [Zn(L)] n was successfully synthesized by solvothermal method, using 1,3,5-tris (3-carboxy-triazole-methylene)-2,4,6-tritoluene (H3L) as organic ligand. Its stucture was characterized by X-ray single-crystal diffraction, elemental analysis, IR spectra and thermogravimetric (TG) analysis. X-ray single-crystal diffraction analysis exhibits that Zn-MOF belongs to the orthorhombic crystal system, space group Pbcn. The central Zn(II) ion exhibits a octahedron {ZnN3O3} coordination geometry. Topological analysis shows that Zn-MOF exhibits a utp uninodal 3-connected 3D 2-interpenetrating framework with the point symbol (10(3)). Furthermore, the fluorescence quenching experimental results show that Zn-MOF is a potential fluorescent material that can selectively and sensitively fluorescent sensing NB. (C) 2020 Elsevier B.V.

Synthesis of [F-18]PS13 and Evaluation as a PET Radioligand for Cyclooxygenase-1 in Monkey

Cyclooxygenase-1 (COX-1) and its isozyme COX-2 are key enzymes in the syntheses of prostanoids. Imaging of COX-1 and COX-2 selective radioligands with positron emission tomography (PET) may clarify how these enzymes are involved in inflammatory conditions and assist in the discovery of improved anti-inflammatory drugs. We have previously labeled the selective high-affinity COX-1 ligand, 1,5-bis(4-methoxyphenyl)-3-(2,2,2-trifluoroethoxy)-1H-1,2,4-triazole (PS13), with carbon-11 (t(1/2) = 20.4 min). This radioligand ([C-11]PS13) has been successful for PET imaging of COX-1 in monkey and human brain and in periphery. [C-11]PS13 is being used in clinical investigations. Alternative labeling of PS13 with fluorine-18 (t(1/2) = 109.8 min) is desirable to provide a longer-lived radioligand in high activity that might be readily distributed among imaging centers. However, labeling of PS13 in its 1,1,1-trifluoroethoxy group is a radiochemical challenge. Here we assess two labeling approaches based on nucleophilic addition of cyclotron-produced [F-18]fluoride ion to gemdifluorovinyl precursors, either to label PS13 in one step or to produce [F-18]2,2,2-trifluoroethyl p-toluenesulfonate for labeling a hydroxyl precursor. From the latter two-step approach, we obtained [F-18]PS13 ready for intravenous injection in a decay-corrected radiochemical yield of 7.9% and with a molar activity of up to 7.9 GBq/mu mol. PET imaging of monkey brain with [F-18]PS13 shows that this radioligand can specifically image and quantify COX-1 without radiodefluorination but with some radioactivity uptake in skull, ascribed to red bone marrow. The development of a new procedure for labeling PS13 with fluorine-18 at a higher molar activity is, however, desirable to suppress occupancy of COX-1 by carrier at baseline.

Single dose pharmacokinetics of topical iodiconazole creams in healthy Chinese volunteers

1.In this study, the pharmacokinetics of new triazole antifungal iodiconzole creams at target sites after single-dose topical application was investigated. 2.30 healthy Chinese volunteers were randomly divided into three groups after being stratified by sex, each group was given a single topical dose of 1%, 2%, 4% iodiconazole cream (0.4 g). Stratum corneum (SC) samples of treated sites were collected by tape-stripping method after the chosen contact times, and were extracted and analysed by a validated LC-MS method. 3.After single-dose topical application of 1%, 2%, 4% iodiconazole creams, the C-max of iodiconazole in SC was 1.2 +/- 0.7, 2.2 +/- 1.0, 2.4 +/- 1.0 mg/g; T-max was 3.3 +/- 1.1, 2.9 +/- 1.1, 3.8 +/- 0.4 h; t(1/2) was 6.6 +/- 3.4 h, 7.2 +/- 4.1 h, 5.9 +/- 2.9 h; AUC(0-t) was 10.9 +/- 3.0, 20.8 +/- 10.4, 20.9 +/- 7.9 mg center dot h/g; AUC(0-infinity) was 11.6 +/- 2.9, 23.5 +/- 14.4, 22.2 +/- 8.9 mg center dot h/g, respectively. The results showed that C-max, AUC(0-t) and AUC(0-infinity) did not increase proportionately with dose, which could also be due to the drug being saturated in the formulation at similar to 2%. 4.The results of this study could provide reference for the clinical medication and further study of the formulations.

A simple and efficient strategy for constructing nitrogen-rich isomeric salts and cocrystal through pK(a) calculation

Nitrogen-rich energetic salts and cocrystal have attracted considerable attention in recent years. To assess the formation of cocrystal or salt, acid dissociation constant (pK(a)) values of the isomeric co-formers were calculated in this work and significant differences were observed. Two salts and one cocrystal based on H2BT (1H, 1’H-5,5′-bitetrazole), DATr (4,5-diamino-4H-1,2,4-triazole), 1MAT (1-methyl-5-aminotetrazole) and 2MAT (2-methyl-5-aminotetrazole) were synthesized, which corresponding to the different pK(a) values of three isomeric coformers. Single crystal structure analysis reveals that all compounds are formed by layered stacking structure with pi-pi stacking and rich hydrogen bonds, resulting in the insensitivity towards impact and friction (impact sensitivity > 40 J, friction sensitivity > 360 N). To the best of our knowledge, it is the first time to report the cocrystal of H2BT. The study results provide a utility method to seek for suitable coformers and design energetic cocrystal through the calculation of pK(a). (C) 2020 Elsevier B.V. All rights reserved.

Synthesis and properties of novel nitrogen- and oxygen-enriched dicationic 3,4-diaminotriazolium salts as attractive energetic materials

The incorporation of both fuel and oxidizer properties into a single molecule to effectively improve the oxygen balance of energetic compounds has become one of the most acceptable strategies for the design of modern high-energy-density materials (HEDMs). To identify more powerful and less sensitive HEDMs with favorable oxygen balance, novel nitrogen- and oxygen-enriched dicationic 3,4-diaminotriazolium salts were prepared via the quaternization of 3,4-diamino-triazole with 4,4′-bis(nitramino)azofurazan and 4,4′-bis(nitramino)azoxyfurazan, and then fully characterized. These compounds exhibited favorable thermal stabilities with decomposition temperatures up to 216 degrees C, high densities over 1.82 g.cm(-3) as well as acceptable sensitivities. In addition, the two-dimensional fingerprint spectra based on Hirshfeld surface analysis were adopted to illustrate structure-property relationships. Based on the combination of experimentally determined densities and heats of formation calculated with Gaussian 03, the energetic properties were determined using the EXPLO5 v6.02 program. The newly synthesized ionic salts displayed excellent detonation properties (V-d, 9115-9220 m.s(-1); P, 33.9-35.4 GPa), comparable to those of 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane (HMX), thus highlighting their potential in energetic material applications.
