Otto Fuel II, a propellant in torpedoes, is composed of 76% 1,2 propanediol dinitrate (PGDN), 22.5% di-n-butyl sebacate, and 1.5% 2-nitrodiphenylamine (NDPA), and is largely recalcitrant to aerobic microbial degradation. Anaerobic microbial degradation of Otto Fuel II was tested by inoculating a...

A series of black and navy-blue disazo acid dyes, derived from 4-amino-2′-nitrodiphenylamine and 1-N-phenylaminonaphthalene-8-sulphonic acid, were synthesized. The dyes were suitable for dyeing polyamide fibres and wool from a weakly acidic dyebath without electrolytes. Spectroscopic data for t...

This chapter presents the Wildlife Toxicity Assessment (WTA) for 2- and 4-nitrodiphenylamine (NDPA). Whereas 2-NDPA is used as a stabilizer for Otto Fuel II, 4-NDPA is strictly an industrial chemical intermediate. This WTA addresses only mammals, as data for amphibians, reptiles, and birds were ...

Disodium 4,4′-bis(1,3,5-triazin-6-yl)diaminostilbene-2,2′-disulfonate derivatives (9a–i) which were asymmetrically substituted with various nucleophilic substituents on triazine moiety were prepared. The obtained compounds were characterized by the analysis of the proton NMR spectrum and conf...

The in silico evaluation for the three previously synthesized compounds (Methyl (MMA), propyl (PMA) and isopropyl (IMA) N-methylanthranilate), MMA and IMA originally found in the leaf essential oil of Choisya ternata, provided a very good confirmation for the in vivo pharmacological results obta...

Two volatile alkaloids, isopropyl N-methylanthranilate (IMA) and methyl N-methylanthranilate (MMA), present in the human diet and cosmetic products, were recently demonstrated to possess important pharmacological activities. While MMA is considered to be phototoxic, there is scarce data on the t...

Two volatile alkaloids, methyl (MMA) and isopropyl N-methylanthranilates (IMA), identified in the essential oil of Choisya ternata Kunth (Rutaceae), have been proven to possess polypharmacological properties (antinociceptive, anti-inflammatory, gastro-, hepato-, nephroprotective activities, anxi...

AimsHerein we investigated the potential protective effects of methyl N-methylanthranilate (MA) and isopropyl N-methylanthranilate (IA), two naturally occurring plant constituents from Rutaceae taxa, in a rat model of acute intoxication with carbon tetrachloride (CCl4) by tracking changes in kid...

Recently, we identified a new natural antinociceptive alkaloid ternanthranin, isopropyl N-methylanthranilate (ISOAN), from the plant species Choisya ternata Kunth (Rutaceae). In this work we concentrated on the elucidation of its mechanism of action in comparison with two other esters of this ac...

A 2:1 complex between cyclomaltoheptaose (β-cyclodextrin) and N-methylanthranilic acid has been studied in the solid state. The inclusion complex belongs to the triclinic system (space group P1) with unit cell dimensions a = 15.2773(15) Å, b = 15.4710(15) Å, c = 17.9627(18) Å, α = 99.632(5)°,...

In this work, the values of pk12 and pk22 microdissociation constants of three aromatic amino acids (anthranilic (AA), N-methylanthranilic (MeAA) and N-phenylanthranilic (PhAA)) were calculated using density functional theory (DFT). Aqueous-phase energies and solvation energies were calculated u...

The electropolymerization of N-methylanthranilic acid (NMAA) is reported in this paper. The monomer is substituted both at ortho- and N-position and, to the best of our knowledge, it has not been previously electropolymerized. Electropolymerization of NMAA was done on glassy carbon and optically...

Azinphos-methyl (AZM) is a widely used organophosphate insecticide and acaricide, with demonstrated negative impacts on the environment. Upon absorption of UV-A radiation, this molecule undergoes photolysis to the highly fluorescent compound N-methylanthranilic acid, which undergoes subsequent p...

In this study, we investigated the thermal and alternating current (ac) electrical properties of N-methylanthranilic acid. Based on data obtained by differential scanning calorimetry, we detected two endothermic transitions at ≈ 213 K and ≈265.41 K. The weakening of hydrogen bonds as the tempe...

Ni(II) and Cu(II) complexes of 2-carboxybenzaldehyde thiosemicarbazone (L) were synthesized and investigated by their spectral and analytical data. These newly synthesized complexes have a composition of M(L)X(H2O)2 (where M = Ni(II), Cu(II) and X = Cl−, NO3-, CH3COO−) and (L) is the tridentate ...

The 1,4-dipoles derived from isoquinolines and methyl perfluoroalk-2-ynoates reacted readily with arylidene-substituted N,N-dimethylbarbituric acids resulting in the first diastereoselective synthesis of perfluoroalkylated cis-spiropyrido[2,1-a]isoquinoline-1,5’-pyrimidine derivatives in good t...

Thermoregulated phase-transfer Pt nanocatalyst was shown to be highly active, selective and recyclable in the hydrogenation of quinolines and isoquinolines. The catalyst could be easily separated from the product by simple phase separation and directly reused in the next cycle without evident lo...

The phytochemical study on Corydalis tomentella Franch, a traditional Chinese medicinal plant in Tibet, China, led to the isolation of six previously undescribed isoquinolines, including two rarely reported N-benzyl ones, and twenty-one known ones firstly obtained from this plant. Their planar s...

A highly efficient approach to synthesize isoquinoline derivatives through Iridium(III)-catalyzed cyclization of aryl ketoximes and internal alkynes without oxidant is reported. A broad range isoquinolines are obtained in good to excellent yields and various functional groups are well tolerated.

Phytochemical investigation of the aerial parts of Glaucium arabicum Fresen. (Papaveraceae) led to the isolation of two previously undescribed isoquinoline alkaloids araglaucine A, and araglaucine B, together with seven known ones 1-[(3`,4`-dimethoxy-2`-methylcarboxy)benzoyl]-6,7-methylenedioxy ...
