Several metals were found to catalyze the conversion of benzotrifluoride to benzoyl fluoride in the presence of carboxylic acids and sulfonic acids, together with the corresponding anhydride, and molecular oxygen. Nb2O5 exhibited the highest activity, and a conversion of 99.8% and a selectivity of 90% were obtained in 10 min under mild conditions. The composition of the acid and anhydride was f...
In the structure of the title compound (N26DCP2CBA), C(13)H(8)Cl(3)NO, the conformations of N-H and C=O bonds in the amide group are trans to each other, similar to that observed in N-(2,6-dichloro-phen-yl)benzamide, 2-chloro-N-phenyl-benzamide, 2-chloro-N-(2-chloro-phen-yl)benzamide and 2-chloro-N-(2,3-dichloro-phen-yl)benzamide with similar bond parameters. Furthermore, the position of the am...
In the structure of the title compound (N2CP2MBA), C(14)H(12)ClNO, the conformations of the N-H and C=O bonds are trans to each other. Furthermore, the conformation of the N-H bond is syn to the ortho-chloro group in the aniline ring and the C=O bond is syn to the ortho-methyl substituent in the benzoyl ring, similar to what is observed in 2-chloro-N-(2-chloro-phen-yl)benzamide and 2-methyl-N-p...
In the title compound, C20H13ClO3, the dihedral angles between the benzoate and the chloro-benzene and benzoyl rings are 68.82 (5) and 53.76 (6)°, respectively, while the dihedral angle between the benzoyl and benzoate rings is 81.17 (5)°. The eight atoms of the benzoyl residue are essentially planar with the exception of the O atom which lies 0.1860 (5) Å out of their mean plane (r.m.s. deviat...
Toxoplasma gondii is a protozoan parasite that can damage the human brain and eyes. There are no curative medicines. Herein, we describe our discovery of N-benzoyl-2-hydroxybenzamides as a class of compounds effective in the low nanomolar range against T. gondii in vitro and in vivo. Our lead compound, QQ-437, displays robust activity against the parasite and could be useful as a new scaffold f...
1. Rat liver mitochondria make hippurate at up to 4 nmol/min per mg of protein. The rate of synthesis supported by oxidation of glutamate with exogenous Pi present is identical with that supported by ATP plus oligomycin. Lower rates were obtained with other respiratory substrates, and when glutamate was used without Pi. 2. A matrix localization for hippurate synthesis is indicated by the latenc...
The widely used topical agents anthralin and benzoyl peroxide are potent skin irritants. In the mouse skin model these compounds produce hyperplasia nd are effective skin tumor promoters. In the present studies, we have examined the effects of anthralin and benzoyl peroxide on epidermal proteins and compared them with changes produced by the potent phorbol ester tumor promoter 12-O-tetradecanoy...
