MedKoo Cat#: 407946 | Name: WM-1119
Featured New

Description:

WARNING: This product is for research use only, not for human or veterinary use.

WM-1119 is a highly potent, selective inhibitor of lysine acetyltransferase KAT6A with Kd of 2 nM, WM-1119 is a reversible competitor of acetyl coenzyme A and inhibits MYST-catalysed histone acetylation. WM-1119 induces cell cycle exit and cellular senescence without causing DNA damage. WM-1119 arrests the progression of lymphoma in mice.

More Info
Acetylation of histones by lysine acetyltransferases (KATs) is essential for chromatin organization and function1. Among the genes coding for the MYST family of KATs (KAT5-KAT8) are the oncogenes KAT6A (also known as MOZ) and KAT6B (also known as MORF and QKF). KAT6A has essential roles in normal haematopoietic stem cells and is the target of recurrent chromosomal translocations, causing acute myeloid leukaemia. Similarly, chromosomal translocations in KAT6B have been identified in diverse cancers8. KAT6A suppresses cellular senescence through the regulation of suppressors of the CDKN2A locus, a function that requires its KAT activity. Loss of one allele of KAT6A extends the median survival of mice with MYC-induced lymphoma from 105 to 413 days11. These findings suggest that inhibition of KAT6A and KAT6B may provide a therapeutic benefit in cancer
Biological target:
WM-1119 is a KAT6A inhibitor, with an IC50 of 0.25 μM for KAT6A in lymphoma cells.
In vitro activity:
Treatment of MEFs with WM-1119 resulted in cell cycle arrest in G1 and a senescence phenotype similar to that seen upon treatment with WM-8014 (Extended Data Fig. 8). Notably, the activity of WM-1119 in this cell-based assay is an order of magnitude greater than WM-8014 and WM-1119 is able to induce cell cycle arrest at 1 µM. Reference: Nature. 2018 Aug;560(7717):253-257. https://pubmed.ncbi.nlm.nih.gov/30069049/
In vivo activity:
Treatment with WM-1119 three times per day led to a significant reduction in tumour burden and spleen weight, but was not as effective as treatment four times per day (Fig. 4d, f). WM-1119 was well-tolerated; mice showed no generalized ill effects and weight loss was not observed (Extended Data Fig. 10). WM-1119 treatment had no effect on haematocrit, erythrocytes or platelet numbers, but there was overall leukopenia (Extended Data Fig. 10). The proportion and overall number of tumour cells was substantially reduced by WM-1119 treatment (four times per day; Fig. 4g). Analysis by intracellular flow cytometry demonstrated a reduction in H3K9ac in tumour cells (P = 0.03; Extended Data Fig. 10). These results demonstrate that WM-1119 is effective in treating lymphoma in vivo. Reference: Nature. 2018 Aug;560(7717):253-257. https://pubmed.ncbi.nlm.nih.gov/30069049/
