- Discovery of new tranylcypromine derivatives as highly potent LSD1 inhibitors
-
Tranylcypromine (TCP)-based structural modifications lead to the discovery of new LSD1 inhibitors, of which compounds 26b and 29b effectively inhibit LSD1 with the IC50 values of 17 and 11 nM, respectively and also show good selectivity over MAO-B. Mechanistic studies showed that compound 29b concentration-dependently induced H3K4me1/2 accumulation in LSD1 overexpressed MGC-803 cells and also inhibited metastasis of MGC-803 cells. Collectively, both compounds could be promising lead compounds for further investigation.

- Asymmetric syntheses of pharmaceuticals containing a cyclopropane moiety using catalytic asymmetric Simmons-Smith reactions of allylalcohols: Syntheses of optically active tranylcypromine and milnacipran
-
Asymmetric synthesis of tranylcypromine was achieved using an enantioselective Simmons-Smith cyclopropanation catalyzed by a simple disulfonamide derived from an -amino acid. The optically active milnacipran was also synthesized by porcine pancreas lipase-catalyzed selective monoacylation of the C4-hydroxy group in (Z)-2-phenylbut-2-ene-1,4-diol and the enantioselective Simmons-Smith cyclopropanation as the key steps.

- Biochemical, structural, and biological evaluation of tranylcypromine derivatives as inhibitors of histone demethylases LSD1 and LSD2
-
LSD1 and LSD2 histone demethylases are implicated in a number of physiological and pathological processes, ranging from tumorigenesis to herpes virus infection. A comprehensive structural, biochemical, and cellular study is presented here to probe the potential of these enzymes for epigenetic therapies. This approach employs tranylcypromine as a chemical scaffold for the design of novel demethylase inhibitors. This drug is a clinically validated antidepressant known to target monoamine oxidases A and B. These two flavoenzymes are structurally related to LSD1 and LSD2. Mechanistic and crystallographic studies of tranylcypromine inhibition reveal a lack of selectivity and differing covalent modifications of the FAD cofactor depending on the enantiomeric form. These findings are pharmacologically relevant, since tranylcypromine is currently administered as a racemic mixture. A large set of tranylcypromine analogues were synthesized and screened for inhibitory activities. We found that the common evolutionary origin of LSD and MAO enzymes, despite their unrelated functions and substrate specificities, is reflected in related ligand-binding properties. A few compounds with partial enzyme selectivity were identified. The biological activity of one of these new inhibitors was evaluated with a cellular model of acute promyelocytic leukemia chosen since its pathogenesis includes aberrant activities of several chromatin modifiers. Marked effects on cell differentiation and an unprecedented synergistic activity with antileukemia drugs were observed. These data demonstrate that these LSD1/2 inhibitors are of potential relevance for the treatment of promyelocytic leukemia and, more generally, as tools to alter chromatin state with promise of a block of tumor progression.

- Synthesis of the enantiomer of the antidepressant tranylcypromine
-
Both enantiomers of the antidepressant tranylcypromine, trans 2-phenyl-cyclopropylamine 1, were prepared in enantiomerically pure form by a chemoenzymatic approach starting from racemic (±)-(1RS, 2RS)-trans ethyl 2-phenyl-cyclopropane carboxylate (±)-3.
