Nevirapininium picrate [PDF]

Acta Crystallographica Section E Structure Reports Online, 2007
The title compound, C15H15N4O+·C6H2N3O7−, is the picrate salt of nevirapine, in which the cation and anion are linked by an N—H⋯O hydrogen bond. A second N—H⋯O inter­action leads to centrosymmetric dimers of cations. The dihedral angle between the aromatic ring planes in the cation is 48.27 (8)°.

Potential to Improve Nitrogen Fertilizer Use Efficiency and Mitigate Pollution in Tropical Pastures Grazed by Sheep

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
We hypothesize that increasing N application rates will affect N use efficiency (NUE) for lambs grazing warm‐season annual grasses. We evaluated the effect of N fertilizer application rates (50, 100, 200, and 400 kg N/ha) on forage pearl millet (Pennisetum glaucum (L.) R.) and animal responses: N balance and NUE per animal and per area basis.

We Licked the Toads so You Don’t Have to: A Comprehensive Analysis of the Chemical Syntheses of the Classical Psychedelics Bufotenin(e) and 5‐Methoxy‐N,N‐Dimethyltryptamine

ChemMedChem, Volume 21, Issue 4, 25 February 2026.
The psychedelics 5‐MeO‐DMT and bufotenin—famously secreted by some toads—have been made in many different ways since 1936. Bufotenin (also spelt as bufotenine) and its methylated derivative, 5‐methoxy‐N,N‐dimethyltryptamine (5‐MeO‐DMT), are potent psychedelics that are found in many plants but also excreted by some species of toads.
