A binuclear zinc complex of the 2,6-bis [(2-pyridylmethyl)(2-hydroxyethyl) amino]methyl -4-methylphenol ligand (L33, Fig. 63) catalyzes the hydrolysis of bis(4-nitrophenyl) phosphate in aqueous buffer solution to yield 4-nitrophenol and 4-nitrophenyl phosphate.246 Analysis of the pH-rate profile revealed a sigmoidalshaped curve with a pKa = 7.13. This value is similar to a deprotonation event characterized by potentiometric titration and has been assigned to deprotonation of...

A further example of pyrazolone dye is Acid Red 38. This dye is the chromium complex of the azo compound made by coupling diazotized 2-amino-5-nitrophenol with meta-(3-methyl-5-oxo-2-pyrazolin-l-yl)-benzene-sulfonamide. It is used as a dye for wool and nylon. Acid Red 38 has one advantage over dyes such as Mordant Black 17 in that the dyer does not have to form the chromium complex by a separate operation during the dyeing process.

The required 4-amino-7-methylbenzofuran (1103) was prepared starting from the commercial 2-methyl-3-nitrophenol (1104) over five steps in 52% overall yield. In this sequence, the key step is the annulation of the furan ring using bromoacetaldehyde... 

The northeast Pacific bryozoans Phidolopora pacifica contained two nitrophenols, desmethylphidolopin (448) and 3-nitro-4-hydroxybenzyl alcohol (449) (365). Desmethylphidolopin (448) showed antimicrobial activity. 2-Amino-6-[(r/ ,2 5)-l, 2 -dihydroxypropyl]-3-methyl pterin-4-one (450) was isolated from the anthozoan Astroides calycularis collected in the Bay of Naples and exhibited cell growth-inhibiting activity (366). The structure of leucettidine, a pteridine derivative found in Leucetta microra-... 

Analytical standards. Fenitrothion (1 C-ring-labelied, sp. act. 73.7 pCi/mg) was provided by Sumitomo Chemical Co. Ltd.. Fenitrothion, fenitrooxon (FO), S-methyl fenitrothion (SMF), and amino-fenitrothion (AF) were obtained from R. Greenhalgh (Agriculture Canada, Ottawa). The hydrolysis product 3-methyl-4-nitrophenol (MNP) was obtained from Aldrich Chemicals, St. Louis. Standards were prepared in ethyl acetate or methanol.

Dinitroorthocresol (DNOC, 36), the metabolism of which has been studied most extensively, is excreted in the urine of rabbits at a rate of about 20% in 48 hours, of which 5-6% is voided in the form of the free compound, about 1 % as O-conjugate (37) and 12% mainly as 2-acetamino-6-methyl-4-nitrophenol O-conjugate (38). The metabolites 3-amino-5-nitrosalicylic acid and 4-amino-6-methyl-2-nitro-phenol have been observed in trace quantities. The amino groups formed by... 

Study of the metabolism of dinoseb and its acetate and of binapacryl in rabbits showed that 2-amino-6-sec-butyI-4-nitrophenol (39) is formed aiid excreted as O-conjugate with glucuronic acid, glucuronide (40). In rats this metabolism appears only in traces, but for both compounds the oxidation of the side chain — and thus the formation of -methyl-/ -(2-hydroxy-3,5-dinitrophenyl)propionic acid (41) in considerable quantities, also excreted in the urine — has b n detected. The evacuation of nitro compounds from warm-blooded organisms is relatively slow. 

Enantiomeric differentiation during the thiolysis of a-amino acid ester salts by two thiol-bearing 18-crown-6 derivatives prepared from (1/ , 2/ , 35, 45)- and R, 2S, 3R, 45)-camphane-2,3-diols has also been demonstrated [74]. Discrimination by factors of 1.7-1.9 in the rates of p-nitrophenol release from the enantiomers of alanine-p-nitrophenyl ester salts has been observed. By contrast, the tetrakis-L-cysteinyl methyl ester receptor molecule l,l-l,l,l,l-(60) exhibits [75] extremely high... 

Permethylation of hydroxyl groups makes the 06 side narrower because of the sharp inclination of 2,3,6-tri-O-methylglucose units caused by the steric hindrance between methyl groups bonded to 03 and 02 of adjacent 2,3,6-tri-O-methylglucose unit. As the result, m-nitroaniline [187] and p-nitrophenol [197] are included with their hydroxyl or amino group located at the 06 side, that is, in the orientation upside down compared with the corresponding complex with the parent a-CyD (Fig.
