We report here the design, synthesis, and pharmacological properties of a series of compounds related to tranylcypromine (9), which itself was discovered as a lead compound in a high-throughput screening campaign. Starting from 9, which shows modest activity as a 5-HT2C agonist, a series of 1-aminomethyl-2- phenylcyclopropanes was investigated as 5-HT2C agonists through iterative structural modifications. Key pharmacophore feature of this new class of ligands is a 2-aminomethyl-trans-cyclopropyl side chain attached to a substituted be zene ring. Among the tested compounds, several were potent and efficacious 5-HT2C receptor agonists with selectivity over both 5-HT2A and 5-HT2B receptors in functional assays. The most promising compound is 37, with 120- and 14-fold selectivity over 5-HT 2A and 5-HT2B, respectively (EC50) 585, 65, and 4.8 nM at the 2A, 2B, and 2C subtypes, respectively). In animal studies, compound 37 (10-60 mg/kg) decreased immobility time in the mouse forced swim test.

Irradiation of trans(2-arylcyclopropyl)methyl acetates a 4-butenyl-1-arylacetate (7a,b,d-h) via an ionic mechanism from the singlet state. Similar rearrangements occurred with exo-(1,1a,6,6a-tetrahydrocycloprop left bracket a right bracket inden-1-yl)methyl acetate and the 4-cyano derivative. Excited state reaction rate constants were determined from reactant fluorescence lifetimes and product quantum yields. It is concluded that the rate-determining step involves conversion of the initially formed aromatic excited state to a reactive cyclopropane excited state and that cyclopropane to aromatic ring charge transfer enhances this process.
