The structure of the title compound, C(11)H(12)BrN(2)S(+)·C(2)HO(4) (-) (common name 6-bromo-levamisole hydrogen oxalate), is stabilized mainly by hydrogen bonds. Hydrogen oxalate anions form parallel coplanar chains via O-H⋯O hydrogen bonds, while there are N-H⋯O hydrogen-bonding inter-actions between the 6-bromo-levamisole cations and oxalate anions. Both five-membered rings from the 6-bromo-...

The title compound, C(15)H(10)Br(2)O, is a chalcone with 2-bromo-phenyl and 4-bromo-phenyl rings bonded to opposite sides of a propenone group. The dihedral angle between mean planes of the benzene rings is 71.3 (1)°. The angle between the mean plane of the prop-2-ene-1-one group and the mean planes of the 2-bromo-phenyl and 4-bromo-phenyl rings are 64.2 (9) and 71.3 (1)°, respectively. A weak ...

Abstract A boron trifluoride catalysed reaction of coplanar 9-(phenyl­ethynyl)-9H-fluoren-9-ols with various 2-aminobenzamides affords a number highly functionalized, conjugated (Z)-2-((2-(9H-fluoren-9-ylidene)-1-phenylethylidene)amino) benzamides in excellent yield. The the presence N-bromosuccinimide (E)-5-bromo-2-((2-bromo-2-(9H-fluoren-9-ylidene)-1-phenylethylidene)amino)benz­amides very go...

In the mol-ecule of the title compound, C(17)H(16)BrN(3)O, the triazole ring is oriented at dihedral angles of 6.14 (9)° and 82.08 (9)°, respectively, with respect to the phenyl and bromo-benzene rings. The dihedral angle between the bromo-benzene and phenyl rings is 87.28 (7)°. The intra-molecular C-H⋯O hydrogen bond results in the formation of a planar five-membered ring, which is oriented at...

Previously we have shown that long-term pretreatment of JEG-3 choriocarcinoma cells with 8-bromo-cAMP increases the capacity for N-glycosylation that was caused by an 8-10-fold enlargement of the dolichol pyrophosphoryl oligosaccharide (Dol-PP-oligosaccharide) pool [Konrad and Merz (1994) J. Biol. Chem. 269, 8659-8666]. The factors involved in the effect of cAMP on synthesis of Dol-PP-oligosacc...

ABSTRACT. Among oxygen-containing heterocyclic compounds such as coumarin and azacoumarin derivatives, the scaffold has become an important construction motif for developing new drugs. Coumarin its derivatives possess many types of biological activities have been reported to show significant cytotoxic activity. N-(6,8-disubstituted coumarin-3-yl)benzamides (8a-c) namely (3-N-(benzoyl) aminocoum...

Despite its transport by glucose transporters (GLUTs) in vitro, it is unknown whether dehydroascorbic acid (oxidized vitamin C, DHA) has any in vivo function. To investigate, we created a chemical transport knockout model using the vitamin C analog 6-bromo-ascorbate. This analog is transported on sodium-dependent vitamin C transporters but its oxidized form, 6-bromo-dehydroascorbic acid, is not...

Cytotrophoblasts, purified from human term placentae, were cultured in the absence or presence of 8-bromo-cAMP or 8-bromo-cGMP. 8-Bromo-cAMP provoked a dose-dependent increase in the secretion of hCG and progesterone within 24 h. After 48 h, hCG secretion increased by more than 200-fold, and progesterone secretion increased nearly 5-fold. 8-Bromo-cGMP had no effect on hCG secretion. In culture ...
