A new selective reagent was used for simultaneous determination of mercury and palladium in real samples with their different kinetic spectrophotometric properties. The method is based on the difference in the rate of the oxidation reaction of the recently synthesized reagent, nitro benzoyl diphenylmethylen phosphorane (N-BDMP), with Hg2+ and Pd2+. The kinetic profiles were monitored and record...

A series of five-membered heterocyclic rings were synthesized by the reaction between benzoyl chloride and various chlolro-nitro-benzoyl chlorides and semi carbazide to form (C1-C7) compounds and was tested for their anti-inflammatory activity determined by rat-paw-oedema method. All the synthesis compounds have been characterized by 1HNMR, IR and Mass spectral data. The compounds were purified...

Organic extracts of six urine samples from children treated with nitisinone, a medicine against tyrosinemia type I, were investigated by (1)H and (19)F NMR spectroscopy. The presence of unchanged 2-[2-nitro-4-(trifluoromethyl)benzoyl]cyclohexane-1,3-dione (NTBC), 6-hydroxy-2-[2-nitro-4-(trifluoromethyl)benzoyl]cyclohexane-1,3-dione (NTBC-OH) and 2-nitro-4-trifluoromethylbenzoic acid (NTFA) as w...

Several cycline dependent kinase 2 (CDK2) inhibitors with different chemical structures have been introduced. The hinge region of CDK2 (residues 81–84) contains a set of hydrogen bond donor and acceptor sites some of which must be satisfied for potent inhibitor binding. The benzimidazolone skeleton may provide such interactions. Accordingly, 3-sulfonamide substituted benzamido-benzimidazolones ...

In the mol-ecular structure of the title compound, C23H14N4O7, the furan, di-nitro-phenyl and phenyl rings are almost in the same plane (r.m.s. deviation = 0.127 Å), with the benzoyl ring inclined by a dihedral angle of 56.4 (1)° to the three-ring system. A bifurcated intra-molecular N-H⋯(O,O) hydrogen bond is present. In the crystal, adjacent mol-ecules are linked by C-H⋯O hydrogen bonds into ...

A number of 5-nitrothiazoles with various substituents in the 2-position were tested for inhibition of Clostridium botulinum in a culture medium. Thiazole itself or 2-bromo- or 2-methylthiazole at 30 mug/ml did not inhibit the organism. An amino group in the 2-position of thiazole inhibited at 10 mug/ml. Substitution of a nitro group in the 5-position of 2-aminothiazole increased the inhibitory...
