METTL1-WDR4-IN-1
Based on 2 publication(s) in Google Scholar
METTL1-WDR4-IN-1 (Compound 1) is a selective competitive inhibitor of the methyltransferase complex METTL1-WDR4 (IC50 = 144 μM). METTL1-WDR4-IN-1 inhibits the m7G methyltransferase activity of the METTL1-WDR4 complex, blocking m7G modification of PKM mRNA, reducing PKM2 protein expression, disrupting the METTL1/PKM2/H3K9la positive feedback loop, and simultaneously inhibiting PKM2 nuclear translocation-mediated CD155 transcriptional activation. METTL1-WDR4-IN-1 can inhibit tumor cell proliferation, weaken glycolytic metabolism, reverse tumor immune evasion (restoring NK cell and CD8+ T cell function), and regulate RNA epigenetic modification and the tumor immune microenvironment. METTL1-WDR4-IN-1 can be used in immunotherapy research for cancers such as colorectal cancer, and is particularly suitable for use in combination with PKM2 inhibitors to enhance anti-tumor treatment efficacy.

Biological Activity
IC50: 144 μM (METTL1-WDR4)[1].
METTL1-WDR4-IN-1, as a METTL1 inhibitor, downregulates METTL1 protein and mRNA expression in HCT-116 and RKO CRC cells, inhibits m7G modification of PKM mRNA, and reduces PKM2 protein levels[2].
METTL1-WDR4-IN-1 inhibits glycolysis in CRC cells, reducing extracellular acidification rate (ECAR) and lactate accumulation, and downregulating H3K9la histone modification levels[2].
METTL1-WDR4-IN-1 inhibits PKM2 nuclear translocation in CRC cells, reduces CD155 transcription and protein expression, and enhances the expression of NK cell activation-related markers CD107a and CD16[2].
METTL1-WDR4-IN-1, in combination with the PKM2 inhibitor Shikonin, synergistically downregulates PKM2, H3K9la, and CD155 expression in CRC cells and synergistically inhibits cell proliferation[2].
