Benzoyl coenzyme A and hippurate synthesis.
The synthesis of p-aminohippurate’ by the insoluble particles of rat liver and kidney homogenates occurs at the expense of phosphate bond energy. Cohen and McGilvery (1) have shown that the necessary energy is provided in an aerobic system by the oxidative reactions of the tricarboxylic acid cycle and in an anaerobic system by ATP. Studies by Kielley and Schneider (2) indicate that the enzymes ...
متن کاملPhotochemical synthesis of benzoyl spiro[2.2]pentanes.
In the present study, we describe the photochemical behaviour of 2-mesyloxy phenyl ketones 8 and 12 bearing a cyclopropane moiety in the side-chain. Irradiation of 8 and 12 leads to the corresponding benzoyl spiro[2.2]pentanes as a consequence of an initial gamma-H-shift, subsequent elimination of MsOH (accompanied by a spin-center shift) and cyclization of the resulting 1,3-diradicals. In cont...
متن کاملTretinoin and Benzoyl Peroxide
A simple, sensitive, spectrophotometric method in UV region has been developed for the simultaneous estimation of benzoyl peroxide and tretinoin in bulk and semi solid dosage form (cream). Standard solution of benzoyl peroxide shows maximum absorbance at 234.8 nm and tretinoin shows maximum absorbance at 348.6 nm. Beer’s Lamberts law is obeyed in concentration range 1-9 μg/ml for tretinoin with...
متن کامل1-Benzoyl-4-thiobiuret
IN THE TITLE COMPOUND (SYSTEMATIC NAME {[(phenyl-formamido)-carbon-yl]amino}-methane-thio-amide), C9H9N3O2S, both benzoyl and terminal thio-urea fragments adopt transoid conformations with respect to the central carbonyl O atom. The benzoyl and thio-biuret groups are almost coplanar, making a dihedral angle of 4.40 (8)°. The mol-ecular structure is stabilized by two intra-molecular N-H⋯O hydrog...
متن کاملN-Benzoyl-2-methylbenzenesulfonamide
In the title compound, C(14)H(13)NO(3)S, the conformation of the N-H bond in the C-SO(2)-NH-C(O) segment is anti to the C=O bond. The tolyl and benzoyl groups are twisted about the S-N bond, with a C-S-N-C torsion angle of 68.8 (4)°. The dihedral angle between the sulfonyl and the benzoyl benzene rings is 73.9 (1)°. In the crystal, the mol-ecules are linked into C(4) chains along the c axis by ...
