3,7-Dichloroquinoline-8-carboxylic acid
THE TITLE COMPOUND (TRADE NAME: quinclorac), C(10)H(5)Cl(2)NO(2), was crystallized from a dimethyl sulfoxide solution. Quinclorac mol-ecules are packed mainly via π-π stacking inter-actions between neighbouring heterocycles (interplanar distance: 3.31 Å) and via O-H⋯N hydrogen bonding.
متن کامل(2S,3S)-3-(4-Chlorophenyl)-8-methyltropane-2-carboxylic acid
In the title compound, C(15)H(18)ClNO(2), the inter-nal torsion angles of the tropane ring are comparable to those of tropane rings in the crystal structures reported for cocaine and its derivatives. There is an intra-molecular hydrogen bond between the N atom in the tropane ring and the O atom of the carboxyl group. The crystal structure is further stabilized by many weak C-H⋯O inter-actions b...
متن کاملThe Metabolism of Xanthine-8-carboxylic Acid by Alcaligenes Faecalis.
Alcaligenes jaecalis is capable of growing in response to simple pteridines as the sole source of nitrogen (1). Simple pteridines appear to be metabolized in this organism through the common intermediate, tetraoxypteridine (1, 2)) and cell-free extracts of the organism catalyze the conversion of tetraoxypteridine to xanthine-8-carboxylic acid (1). In these conversions the nitrogen atoms of the ...
متن کاملCarboxylic Acid Production
Carboxylic acids are central compounds in cellular metabolism, and in the carbon cycle in nature. Carbon dioxide is captured from the atmosphere and enters living cells through the formation of carboxylic groups, and it is released from living cells by the decarboxylation of carboxylic acids. The aerobic extraction of free energy from sugars in cellular respiration hinges on the ingeniously des...
متن کامل3β-Hydroxyfriedelan-17β-carboxylic acid
The title compound, C(30)H(50)O(3), which was isolated from a marine endophytic fungus, is a new friedelan derivative. The mol-ecule contains five six-membered rings, which exhibit boat (ring A), distorted boat (ring B) and chair (rings C-E) conformations. The crystal structure is stabilized by inter-molecular O-H⋯O hydrogen bonds, which link neighbouring mol-ecules into 12-membered rings.
