Acta Crystallographica Section E Structure Reports Online, 2011 The asymmetric unit of the title compound, C(18)H(18)BN or (C(6)H(5))(3)B·NH(3), comprises two crystallographically independent but virtually identical mol-ecules. Mol-ecules of one type are linked with each other by N-H⋯π inter-actions, generating an infinite column aligned along the b-axis direction.

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations
Advanced Biology, Volume 9, Issue 3, March 2025.Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Ionization of Ammonia Nanoices With Adsorbed Methanol Molecules
, 2018 Large ammonia clusters represent a model system of ices which are omnipresent throughout the space. The interaction of ammonia ices with other hydrogen-boding molecules such as methanol or water and their behavior upon an ionization are thus relevant in ...
