ChemInform Abstract: CHIROPTICAL PROPERTIES OF AN ISOLATED PYRIDINE CHROMOPHORE: THE CIRCULAR DICHROISM SPECTRA IN THE NEAR ULTRAVIOLET REGION OF (-)-(R)-2-(1,2,2-TRIMETHYLPROPYL)PYRIDINE

Ultraviolet absorption and circular dichroism spectra of the strychnine alkaloids strychnine, β-colubrine, brucine, dihydrostrychnine, dihydro-β-colubrine, and dihydrobrucine have been investigated under various experimental conditions. It appears that at least five electronic transitions are required to account for the spectroscopic properties of these molecules in the ultraviolet region above 190 nm. Transitions, which are tentatively assigned as the 1Lb, 1La, 1Bb, and 1Ba in the notation due to Platt, and an n → π* transition apparently make significant contributions to the spectra of ail of the molecules studied.

Circular Dichroïsm

The circular dichroism (CD) spectra of thirteen lectins, most being specific for D-galactose or N-acetyl-D-galactosamine, were compared. Two groupings are proposed on the basis of the CD in the near-ultraviolet region. Group one comprises the lectins from Arachis hypogaea, Glycine max, Phaseolus coccineus, P. lunatus, P. vulgaris, and Vicia villosa, and group two comprises lectins from Caragana arborescens, Cytisus sessilifolius, Dolichos biflorus, Griffonia simplicifolia, and Wisteria floribunda. The CD spectra of lectins from Bauhinia purpurea and Sophora japonica were different from any of the other lectins. CD difference spectra produced by the two sugars were distinctive for each protein, suggesting that the combining sites of these lectins are not homologous despite similarities in specificity and that the CD spectral similarities arise from residues in other, more homologous regions of the proteins.
