Electron affinities of naphthalene, anthracene and substituted naphthalenes and anthracenes

Organic Mass Spectrometry, 1993
AbstractThe determination of electron transfer equilibria A− + B = A + B− in the gas phase, with a pulsed‐electron high‐pressure mass spectrometer, leads to ΔG1°, ΔH1°, and ΔS1° values. These can be converted into the free energy, enthalpy and entropy changes, ΔGa°(B), ΔHa°(B) and ΔSa°(B), for the reaction e + B = B−, since the corresponding values for

7-Substituted-melatonin and 7-substituted-1-methylmelatonin analogues: Effect of substituents on potency and binding affinity

Bioorganic & Medicinal Chemistry, 2007
A series of 7-substituted melatonin and 1-methylmelatonin analogues were prepared and tested against human and amphibian melatonin receptors. 7-Substituents reduced the agonist potency of all the analogues in the Xenopus laevis melanophore assay, 7-bromomelatonin (5d) and N-butanoyl 7-bromo-5-methoxytryptamine (5f) being the most active compounds, but ...

Hemoglobin Oxygen Affinity and the Design of Red Cell Substitutes

1997
A model is described for evaluating a number of properties of cell-free oxygen carriers with regard to their potential to produce autoregulatory vasoactivity in arterioles. The model is based on the Krogh cylinder, an idealized segment of vessel. It is unique because it “maps” the regulatory region of the arterioles - the precapillary segment which ...
