Potassium p-nitrophenyl sulfate.
The crystal structure of the title compound, K+.C6H4NO6S-, is built up from p-nitrophenyl sulfate anions and potassium cations. Adjacent anions form dimers, which are linked together in a three-dimensional network via short C-H...O contacts. The coordination sphere of the K+ ions may be described as a distorted square antiprism. The crystal structure is further stabilized by pi-pi stacking inte...

was discussed. This compound is a member of a group of organophosphorus insecticides which are powerful inhibitors of cholinesterases. They will also inhibit chymotrypsin, and it has been shown that this inhibition is due to combination of the compounds with a single active centre in the enzyme (Jansen, Nutting & Balls, 1949; Hartley & Kilby, 1952).We investigated the reaction ofchymotrypsin wi...
متن کاملThiophenol: Photoinduced Hydrogen Migration
Reva et al [1] investigated some photoinduced H-transfer isomerization reactions of thiophenol in a solid argon matrix (Figure 1). In this study, the photogenerated isomers – cyclohexa-2,4-diene-1-thione (24) and cyclohexa-2,5diene-1-thione (25) – have never been observed so far. In order to explain the experimental results, our group has performed high level excited-state calculations (CASSCF ...
متن کاملThe kinetics of the reaction of nitrophenyl phosphates with alkaline phosphatase from Escherichia coli.
1. The steady-state rate of hydrolysis of 2,4-dinitrophenyl phosphate catalysed by Escherichia coli phosphatase is identical with that of 4-nitrophenyl phosphate over the pH range 5.5-8.5. 2. The increase in the rate of the enzyme-catalysed decomposition of nitrophenyl phosphates in the presence of tris at pH8.1 and 5.9 is consistent with the hypothesis that tris increases the rate of decomposi...
متن کاملThe inhibition of trypsin. IV. Reaction with diethyl p-nitrophenyl phosphate in the presence of urea.
The inhibition of proteolytic enzymes by organophosphorus compounds has been extensively studied in recent years (1, 2). Such studies have shown that the reaction of trypsin with diisopropyl fluorophosphate (3) or diethyl p-nitrophenyl phosphate (DENP) (4) is accompanied by a loss in the proteolytic, esterase, and amidase activities of this enzyme. It is not certain, however, whether these inhi...
