Storage of Pine Tree Substrate Influences Plant Growth, Nitrification, and Substrate Properties
Pine tree substrate (PTS) is a relatively new substrate for container crop production. There are no detailed studies that elucidate how storage time impacts PTS chemical, physical, and biological aspects. The objective of this research was to determine how PTS storage time influenced PTS chemical …

Synthesis and biological evaluation of novel MPTP analogs as potential monoamine oxidase B inhibitors
… tertiary amines with good monoamine oxidase substrate properties. In addition to its substrate properties, MPTP is a weak mechanism-based inactivator of monoamine oxidase-B (MAO-B). In an attempt to exploit the special interactions between this cyclic tertiary allylamine and MAO-B, studies …

Studies on the monoamine oxidase substrate/inactivator properties of piperidine analogs of the neurotoxin MPTP
The unexpected monoamine oxidase (MAO) substrate properties of 1-cyclopropyl-4-substituted-1 ,2,3,6-tetrahydropyridines have been interpreted in terms of partitioning of these tertiary cyclic allylamines between substrate turnover and ring opening inactivation processes. To evaluate further this …
