DC432 (trifluoroacetate salt)

DC432 is a cell-permeable peptide inhibitor of N-terminal Xaa-Pro-Lys N-methyltransferase 1 (NTMT1, IC50 = 0.054 µM). It binds to NTMT1 and NTMT2 (Kds = 0.3 and 1 µM, respectively) and inhibits N-terminal dimethylation of regulator of chromosome condensation 1 (RCC1) by NTMT1 in a cell-free assay when used at concentrations of 10 and 50 µM. DC432 (100 µM) reduces trimethylation of the RCC1 SPKRIA motif in HCT116 cells.Formal Name: (S)-N-1,28-diamino-6S-carbamoyl-9S,12S,15S,18S,21S-pentakis(3-guanidinopropyl)-1-imino-8,11,14,17,20,23-hexaoxo-2,7,10,13,16,19,22-heptaazaoctacosan-24S-yl)-1-(2-(4-hydroxyphenyl)acetyl)pyrrolidine-2-carboxamide, trifluoroacetate salt.
