Phosphonylated azaheterocycles are an important class of compounds with high biological potential as conformationally restricted bioisosteres of amino acids. Therefore, it is of interest to synthesize conformationally constrained amino phosphonates. We wanted to investigate possible routes via ring opening of alpha-amino phosphonates with an oxanorbornene skeleton, as these can be synthesized w...

In the mol-ecule of the title compound, C(20)H(16)N(2)O(5), the phthalimide fragments are almost planar, with r.m.s. deviations of 0.018 and 0.020 Å, and make a dihedral angle of 53.64 (3)°. The mol-ecular and crystal structures are stabilized by a weak inter-molecular C-H⋯O, C-H⋯π and C=O⋯π [2.883 (1) Å] inter-actions and aromatic π-π stacking inter-actions with a centroid-centroid distance of...

Glycosaminoglycans (GAGs) are linear polysaccharides made by all animal cells. GAGs bind to hundreds of proteins, such as growth factors, cytokines, chemokines, extracellular matrix components, protease inhibitors, proteases, and lipoprotein lipase, through carbohydrate and protein interactions. These interactions control many multicellular processes. The increased use of GAGs isolated from cel...

The asymmetric unit of the title compound, C(22)H(16)N(2)O(4)·2CH(4)O, contains one half-mol-ecule and a methanol solvent mol-ecule. The aromatic ring is oriented at a dihedral angle of 82.91 (3)° with respect to the planar indole ring systems. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into chains along the b axis.

Objective(s): Anticonvulsant activity of phthalimide was discovered in 2000 by molecular hybridization of thalidomide and ameltolide. In our previous research we have reported some new 4-substituted derivatives of phthalimide with good activity against the tonic and clonic seizures Material and Methods: A series of novel 4-flurophthalimides that designed using bioisosteric replacement were synt...

The methylated arginines (MAs) monomethylarginine (MMA), asymmetric dimethylarginine (ADMA), and symmetric dimethylarginine (SDMA) have been shown to be independent predictors of cardiovascular disease. This article describes progress regarding the development of an analytical method capable of rapidly analyzing MAs using capillary electrophoresis (CE) and microchip electrophoresis (MCE) with l...

In vitro studies were performed to characterize [3H]cocaine binding to dark and light ethnic hair types. In vitro binding to hair was selective, was reversible and increased linearly with increasing hair concentration. Scatchard analyses revealed high-affinity (6-112 nM) and low-affinity (906-4433 nM) binding in hair. Competition studies demonstrated that the potencies of 3beta-(4-bromophenyl)t...
