Inhibition of 4-hydroxyphenylpyruvate dioxygenase by 2-[2-nitro-4-(trifluoromethyl)benzoyl]-1,3-cyclohexanedione.
Triketone herbicides are inhibitors of 4-hydroxyphenylpyruvate dioxygenase (HPPD), a key enzyme of the tyrosine transformation pathway, common for plants and animals. One of these herbicides, 2-[2-nitro-4-(trifluoromethyl)benzoyl]-1,3-cyclohexanedione (NTBC), is so selective and efficient that it can be applied as a medicine in a hereditary metabolic disease - tyrosinemia type I. In this paper ...
متن کاملDimethyl 2-(4-methylbenzylidene)malonate
In the mol-ecule of the title compound, C13H14O4, the benzene ring forms dihedral angles of 18.60 (7) and 81.36 (8)° with the two arms of the malonate moiety. The crystal structure features C-H⋯O inter-actions, which form chains running parallel to the b axis.
متن کاملCrystal structure of (2S,4S)-5,5-dimethyl-2-(pyridin-2-yl)-1,3-thiazolidine-4-carboxylic acid
In the title compound, C11H14N2O2S, the thia-zolidine ring has an envelope conformation with the C atom bonded to the carb-oxy-lic acid group at the flap. Two C atoms of the thia-zolidine ring adopt S conformations. In the crystal, O-H⋯N hydrogen bonds between the amine and carb-oxy-lic acid groups construct a helical chain structure along the a-axis direction. The chains are further connected ...
متن کاملDimethyl 2,6-dimethyl-4-(2-nitrophenyl)pyridine-3,5-dicarboxylate
The title compound, C(17)H(16)N(2)O(6), is a decomposition product of the hypertension drug nifedipine [systematic name: dimethyl 2,6-dimethyl-4-(2-nitro-phen-yl)-1,4-dihydro-pyridine-3,5-dicarboxyl-ate]. The dihedral angle between the nitro-sophenyl ring and the pyridine ring is 67.1 (5)°.
متن کاملCharacterization of 2-(2-nitro-4-trifluoromethylbenzoyl)-1,3-cyclohexanedione resistance in pyomelanogenic Pseudomonas aeruginosa DKN343
Pyomelanin is a reddish-brown pigment that provides bacteria and fungi protection from oxidative stress, and is reported to contribute to infection persistence. Production of this pigment can be inhibited by the anti-virulence agent 2-(2-nitro-4-trifluoromethylbenzoyl)-1,3-cyclohexanedione (NTBC). The Pseudomonas aeruginosa clinical isolate DKN343 exhibited high levels of resistance to NTBC, an...
