In the title compound, C(12)H(11)NOS, the dihedral angle between the oxopyridinium and phenyl rings is 58.40 (1)°. The crystal structure is stabilized by C-H⋯O hydrogen bonds, π-π stacking inter-actions involving the pyridinium rings [centroid-centroid distance = 3.6891 (9) Å] and C-H⋯π inter-actions.
In the title compound, C(14)H(30)N(2)O(2), the almost planar nonyl chains are fully extended: the N-C-C-N torsion angle of -161.95 (8)° indicates an anti conformation. The crystal structure features N-H⋯O hydrogen bonds and C-H⋯O inter-actions.
OBJECTIVES Asymmetric dimethylarginine (ADMA) has raised considerable interest, as it is an endogenous inhibitor of nitric oxide synthesis. While increased plasma levels of ADMA have been reported in different cardiovascular disease states, its association with symmetric dimethylarginine (SDMA) has not been evaluated in a prospective population-based study. METHODS AND RESULTS We performed a ...
