Metal complexes of a new ligand derived from 2,3-quinoxalinedithiol and 2,6-bis(bromomethyl)pyridine
In the title compound, C10H14BrNO3, the six-membered lactone ring is in a boat conformation, with the two carbonyl groups cis to one another across the boat basal plane. C-H...O hydrogen bonds and weak C-H...Br interactions stabilize the crystal structure.
A series of new star-shaped trinuclear Ru(II) complexes of imidazo[4,5-f][1,10]phenanthroline derivatives, [{Ru(bpy)(2)}(3){μ-mes(1,4-phO-Izphen)(3)}](ClO(4))(6)·4H(2)O (6), [{Ru(phen)(2)}(3){μ-mes(1,4-phO-Izphen)(3)}](ClO(4))(6)·3H(2)O (7), [{Ru(bpy)(2)}(3){μ-mes(1,2-phO-Izphen)(3)}](ClO(4))(6)·4H(2)O (8), and [{Ru(phen)(2)}(3){μ-mes(1,2-phO-Izphen)(3)}](ClO(4))(6)·3H(2)O (9) [mes(1,4-phO-Izph...
Fibrates are used in biochemical and pharmacological studies as bioactive tools. Nevertheless, most studies have lacked information concerning the concentrations of fibric acids working inside tissues because a simple and sensitive method is not available for their quantitation. This study aimed to develop a simple and sensitive bioanalytical method for the quantitation of clofibric, bezafibric...
Expression and characterization of a novel enantioselective lipase from Acinetobacter species SY-01.
A novel lipase gene, lipase A, of Acinetobacter species SY-01 (A. species SY-01) was cloned, sequenced, and expressed in Bacillus subtilis 168. The deduced amino acid (aa) sequences for the lipase A and its chaperone, lipase-specific chaperone, were found to encode mature proteins of 339 aa (37.2 kDa) and 347 aa (38.1 kDa), respectively. The aa sequence of lipase A and lipase-specific chaperone...
1-Bromovinyl (I), Z-2-bromovinyl (II), 1,2-dibromoethyl (III), and a series of 4-(halomethyl)-2-nitrophenyl (IVa-c) diethyl phosphate esters were examined as substrates and mechanism-based inhibitors for the bacterial phosphotriesterase. All of these compounds were found to act as substrates for the enzyme. Inhibitor I rapidly inactivated the enzyme within 1 min, giving a partition ratio of 230...
