Variable temperature (1)H and (13)C n.m.r. studies in CFCl3/CDCl3 of equilibria in 2-substituted- and 2-substituted-4-methyl-tetrahydropyranes have given conformational enthalpy differences and conformational entropy differences for chloro, methoxy, hydroxy and methylamino substituents.For DeltaHoa->e, the values obtained, in kcal /mol, were 1.67 (Cl), 0.03 (OCH3), -0.63 (OH) and -1.75 (NHCH3); for DeltaSoa->e the values obtained, in cal K-1mol-1 were -1.69 (Cl), -2.52 (OCH3), -2.50 (OH) and -0.60 (NHCH3).The trend in DeltaHo values confirms the importance of antiperiplanar n-?* stabilisation as a contributor to the explanation of the anomeric effect, and supports a suggestion that endo- and exo-anomeric effects which occur in the same conformation are competitive.A variable temperature (13)C n.m.r. study of (Me-(13)C)-4-methyl-tetrahydropyran in CD2Cl2 has given a conformational enthalpy difference (DeltaHoa->e) of -1.86 kcal/mol and a conformational entropy difference (DeltaSoa->e) of -0.07 cal K-1mol-1 for a methyl substituent at the 4-position of a tetrahydropyran.

From a distance: Distance measurements in the nanometer range by means of spin-label electron paramagnetic resonance provide structural evidence for multivalent protein-ligand interactions in solution (see picture; protein subunits: blue/green, ligand: black, spin labels: yellow circles, binding sites: yellow letters). The data show a detailed picture of the binding of divalent ligands to a lectin.

Related Products of 499-40-1. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Like 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal. In a document type is Article, introducing its new discovery.

Two metal coordination polymers with general formula [M(dpa)(C 4O4)(H2O)] [M = Co (1), Ni (2), Zn (3); dpa = 2,2?-dipyridylamine] and [Cu(dpa)(C4O4)(H 2O)]2·H2O (4) have been synthesized under hydrothermal conditions. The single-crystal X-ray analyses reveal that compounds 1-3 are isostructural and possess distorted octahedral metal centers coordinated by two squarates, one dpa, and two water molecules. A 1D two-legged ladder-like framework is formed by interconnection of the water-bridged [M(dpa)(mu2-OH2)]24+ dimeric fragments and mu1,2-squarate ligands. Intra- and intermolecular hydrogen bonds between squarate, water, and dpa ligands, as well as the pi-pi stacking interaction of the pyridyl ring in the dpa ligands, provide extra forces to stabilize the extended network. Conversely, the molecular structure of compound 4 contains two distorted square-pyramidal CuII centers coordinated by two squarates, one dpa ligand, and one water molecule. The squarates adopt a mu1,2-binding mode to link the Cu centers and form a 1D helical chain. For compound 2, the magnetic exchange couplings between metal centers are analyzed with a binuclear magnetic model. The resulting negative magnetic exchange coupling constant indicates an antiferromagnetic interaction within the dimers. The magnetic behavior of compound 4 is typical of paramagnetic CuII ions.

Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme. Irreversible inhibitors are therefore the equivalent of poisons in heterogeneous catalysis. 40191-32-0, C6H9ClO2.
