Eighteen analogues of N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) were synthesized and evaluated as substrates of monoamine oxidase. In general, the flexible analogues, characterized by the presence of a methylene (or ethylene) bridge between the aryl/heteroaryl and tetrahydropyridyl moieties, were better substrates of the enzyme than the conformationally restricted MPTP. It is suggested that the increased oxidative activity of these flexible analogues reflects enhanced binding due to the ability of the C-4-aryl/heteroaryl substituent to gain access to a hydrophobic pocket within the substrate binding site.

The compounds 4, 8, and 10, prepared by standard methods, are converted to the phenylpyridylakanes 9; their methoiodides 11 are reduced to yield the tetrahydropyridines 12. Whereas the cyclisation of 12a gives the isomers 1f and 1g, 12b furnishes only the
