The monoamine oxidase B (MAO-B) substrate properties and distance measurements along the N-1-C-4 axis of 38 1,4-disubstituted-1,2,3,6-tetrahydropyridine derivatives, including seven newly synthesized MPTP analogs, were used to define the maximum size that can be accommodated by the MAO-B active site. Only those compounds measuring less than 12 Angstrom displayed significant MAO-B substrate properties. The behavior of various 4-substituted-1-cyclopropyltetrahydropyl tetrahydropyridine analogs also is discussed in terms of this N-1-C-4 distance parameter in an effort to understand factors which contribute to their substrate vs inactivator properties. We conclude that this distance parameter will predict the majority of substrates vs nonsubstrates with this class of compound.
