High Resolution 1H NMR Studies of Cyclic N-Nitrosoamines
Milewska, M. J.,Polonski, T.
, p. 631 - 635 (1994)
Molecular modeling by molecular mechanics (MM2) calculations were used to predict conformational preferences of cyclic N-nitrosoamines.The results were compared with 1H NMR data.The observed geminal coupling constants 2J were considerably stronger for syn than for anti α-methylene protons and thus appear to be very useful for configurational predictions.The long-range 4J couplings across the nitrogen atom were observed directly from the 1D spectra. - Keywords: NMR 1H NMR Molecular modeling Cyclic N-Nitrosamines 1H,1H Spin-Spin coupling
NICOTINIC ACETYLCHOLINE RECEPTOR LIGANDS AND THE USES THEREOF
-
Page/Page column 282-283, (2010/04/30)
The invention relates to pyridinyl nicotinic acetylcholine receptor ligands, compositions comprising an effective amount of a pyridinyl nicotinic acetylcholine receptor ligand and methods to treat or prevent a condition, such as depression and nicotine dependence, comprising administering to an animal in need thereof an effective amount of a pyridinyl nicotinic acetylcholine receptor ligand.

The synthesis and structure-activity relationships of novel dipeptidyl peptidase IV inhibitors replacing the classical cyanopyrrolidine P1 group with other small nitrogen heterocycles are described. A unique potency enhancement was achieved with β-branched natural and unnatural amino acids, particularly adamantylglycines, linked to a (2S,3R)-2,3-methanopyrrolidine based scaffold.
