Химические свойства

white to light beige powder or chunks

Использование

As with the MAO inhibitor drugs described above, tranylcypromine is also used for depressions that do not respond to other drugs.

Общее описание

A cell-permeable phenylcyclopropylamine that inhibits the monoamine oxidase and histone demethylase activities, respectively, of MAO A/B (K_i = 101.9 and 16.0 M, respectively) and LSD1/2 (K_i = 242.7 and 180.0 M, respectively), four members of a flavin-dependent amine oxidase family enzymes, by a covalent adduct formation with the enzyme-bound FAD. In addition to preventing LSD1-CoREST (Corepressor of RE1-Silencing Transcription factor) complex-mediated H3K4 demethylation (IC₅₀<2 M), TCP also inhibits LSD1-HCF-1 (Host Cell Factor-1) complex-mediated H3K9 demethylase activity, which is demonstrated to be an essential mechanism for the replication and latent infection of the α-herpesviruses HSV and VZV. The combined treatment of 2 M TCP and 10 M CHIR99061 is reported to enable the reprogramming of Oct4/Klf4-transduced primary HNEKs (Human Neonatal Epidermal Keratinocytes) into iPS (induced Pluripotent Stem) cells, albeit at a 100-time lower efficiency as seen in cultures transduced with 4-TFs (Oct44, Klf4, Sox2, and c-Myc).

Биологическая активность

Irreversible inhibitor of lysine-specific demethylase 1 (LSD1/BHC110) and monoamine oxidase (MAO) (K i values are 242, 102 and 16 μ M for LSD1, MAO-A and MAO-B respectively). Inhibits histone demethylation.
