Contenido : |
The aggregation behavior of 6-isocassine and N-methyl-6-isocassine, two piperidin-3-ol alkaloids isolated respectively from the barks of Prosopis nigra and
P. affinis, was investigated using a combination of NOE experiments and diffusion measurements in solvents of varying polarity and hydrogen bonding
capacity. While the NOE enhancements for N-methyl-6-isocassine are positive, regardless of the solvent, those for 6-isocassine shift from negative to positive
when going from chloroform-d to methanol-d4 solution. In addition, despite the self-diffusion coefficients of both compounds being virtually identical in
methanol-d4, N-methyl-6-isocassine diffuses nearly twice as fast as the non-methylated alkaloid in chloroform-d. The changes in rotational and translational
dynamics observed between solvents for 6-isocassine suggest that the molecule forms dimeric head-to-head aggregates in non-polar aprotic environments, a
behavior that could help explain the biological mode of action that has been proposed for this type of alkaloids. |
