Sulfur-Substituted α-Alkyl Phenethylamines as Selective and Reversible MAO-A Inhibitors: Biological Activities, CoMFA Analysis, and Active Site Modeling
摘要:
A series of phenethylamine derivatives with various ring substituents and with or without N-methyl and/or C-alpha methyl or ethyl groups was synthesized and assayed for their ability reversibly to inhibit monoamine oxidase A (MAO-A) and monoamine oxidase B (MAO-B). Several compounds. showed potent and selective MAO-A inhibitory activity (IC50 in the submicromolar range) but none showed appreciable activity toward MAO-B. A three-dimensional quantitative structure-activity relationship study for MAO-A inhibition was performed on the series using comparative molecular field analysis (CoMFA). The resulting model gave a cross-validated q(2) of 0.72 and showed that in this series of compounds steric properties of the substituents were more important than electrostatic effects. Molecular modeling based on the recently published crystal structure of inhibitor-bound MAO-A provided detailed evidence for specific interactions of the ligands with the enzyme, supported by previous references and consistent with results from the CoMFA. On the basis of these results, structural determinants for selectivity of substituted amphetamines for MAO-A are discussed.

Pharmaceutical compositions and their methods of use are provided, where the pharmaceutical compositions comprise an amphetamine prodrug that provides enzymatically-controlled release of amphetamine or an amphetamine analog. The composition can further comprise an enzyme inhibitor that interacts with the enzyme(s) that mediates the enzymatically-controlled release of amphetamine or the amphetamine analog from the amphetamine prodrug so as to attenuate enzymatic cleavage of the amphetamine prodrug.

agonist and a GI enzyme inhibitor. The present disclosure also provides a composition comprising (a) a GI enzyme inhibitor and (b) a first drug that interacts with a second drug to produce an adverse effect when the second drug is co-ingested as a GI enzyme-cleavable prodrug with the first drug. Such an interaction can be additive or synergistic.
