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. |

ABSTRACT.- Agriculture is transitioning towards more sustainable ways of producing food, fiber, and biofuels, with practices aimed at conserving soil resources by prolonging soil occupation with cash or cover crops and balancing the proportion of cereals and winter legumes when increasing the number of crops in the rotation. Likewise, closing nutrient biogeochemical cycles is critical, particularly for N, which requires adjusting fertilizer rates to avoid surplus or soil mining. Winter crops for grain such as wheat (Triticum aestivum L.), pea (Pisum sativum L.), and for cover such as vetch (Vicia sativa L. or Vicia villosa L.) can differentially affect nitrogen (N) dynamics, yield response to N application, and associated efficiency metrics in succeeding late-sown maize (Zea mays L.). This study aimed to (i) quantify maize yield response to N fertilization by considering productivity, economic, and N efficiency metrics in late-sown maize following fallow or composing a double-crop after winter cash crops (wheat and field pea) or cover crop (vetch) and (ii) test whether vetch biomass can be used to predict the response to N fertilization. © 2025 Elsevier B.V. |
