TDI-11055
Based on 1 Customer Validation
TDI-11055 is a selective and orally active eleven-nineteen leukemia (ENL) inhibitor, which displaces ENL from chromatin by blocking its YEATS domain interaction with acylated histones. TDI-11055 inhibits ENL and AF9 YEATS domains with IC50 values of 50 nM and 70 nM, respectively, and no activity against GAS41 or YEATS2. TDI-11055 decreases chromatin occupancy of ENL-associated complexes, impairs transcription elongation, suppresses key oncogenic gene expression programs, and induces differentiation. TDI-11055 can be used for the research of acute myeloid leukemia.

TDI-11055 (8 days) potently inhibits proliferation of MLL-r and NPM1-mutated leukemia cell lines with IC50 values ranging from 0.27 to 7.2 μM, but has minimal effects on non-MLL-r cell lines[1].
TDI-11055 (1-10 μM; 72 h) inhibits the growth of MV4;11 and OCI-AML3 cells, accompanied by a slowing of cell cycle progression and a mild increase in apoptosis[1].
TDI-11055 (1-10 μM; ~7 days) impairs clonogenic potential of MLL-r MV4;11 and NPM1-mutated OCI-AML3 cells but not non-MLL-r HL60 or K562 cells[1].
TDI-11055 (5 μM; 24 hours) suppresses ENL-dependent oncogenic gene expression programs in MV4;11 cells, including MYC and HOXA cluster genes, and induces myeloid differentiation[1].
TDI-11055 (5 μM; 30 minutes, 2 hours, or 24 hours) rapidly displaces ENL from chromatin, reducing SEC/P-TEFb and DOT1L occupancy and Pol II S2P levels at top ENL-bound genes in MV4;11 cells[1].
TDI-11055 (1-10 μM; ~2 weeks) impairs clonogenic potential of MLL-r and NPM1-mutated primary AML samples but not normal hematopoietic cells[1].
TDI-11055 (8-day) inhibits the growth of MV4;11 AML cells with an IC50 of 0.10 μM in a viability assay[2].
