DNMT1 HDAC-IN-1 (compound (R)-23a), a potent dual inhibitor targeting both DNMT1 and HDAC, exhibits impressive inhibitory effects specifically on HDAC1 (HDAC1:IC50=0.05 μM), a major HDAC isoform that interacts with DNMT1 across multiple protein complexes involved in the transcriptional silencing of TSGs. This compound has been shown to remodel the tumor immune microenvironment and induce tumor regression, effectively reversing cancer-specific epigenetic abnormalities.

DNMT1-IN-5 (Compound 55) is an inhibitor of DNMT, specifically targeting DNMT1 and DNMT3A, with IC50 values of 2.42 μM and 14.4 μM, respectively. It demonstrates antiproliferative effects across various cancer cell lines (TMD-8, DOHH2, MOLM-13, THP-1, RPIM-8226, and HCT116) with IC50 values ranging from 0.19 to 2.37 μM. The compound induces G2 M phase cell cycle arrest and apoptosis in TMD-8 and DOHH2 cells. Additionally, DNMT1-IN-5 exhibits antitumor efficacy in a TMD-8 xenograft mouse model.

IMP-1088 is a potent inhibitor of human N-myristoyltransferases NMT1 and NMT2 dual.

PCLX-001 is a small-molecule compound that acts as an orally active inhibitor of N-myristoyltransferase (NMT), specifically targeting NMT1 and NMT2 with IC50 values of 5 nM and 8 nM, respectively. This compound demonstrates anti-tumor effects and effectively inhibits the early signaling of B-cell receptor (BCR). Consequently, PCLX-001 is a valuable tool for researching B-cell malignancies [1] [2].
