FTO inhibitor CS1 (NSC 337766) is a potent, selective small-molecule inhibitor of m6A demethylase FTO, inhibits m6A demethylation with IC50 of 142.6 nM in vitro (cell-free) assays.CS1 is highly efficacious FTO inhibitors with potent anti-leukemic efficacy againsta panel of leukemia cell lines with high FTO expression in vitro (IC50 range from 20 to 175 nM, MV4-11 IC50=58.9 nM).CS1 blocks the binding of FTO with its known target mRNAs, such as MYC, CEBPA, and RARA, notably increased global m6A abundance in AML cells, does not suppress the enzymatic activity of ALKBH5, or TET1.CS1 treatment resulted in substantially increased apoptosis and cell cycle arrest (at the G0 phase), also significantly promoted myeloid differentiation in human AML cells.FTO inhibitor CS1 substantially delayed AML progression and improved survival in AML PDX mouse model, significantly more effective than FB23-2.
MC2652 (compound 1a) is a potent LSD1 inhibitor. MC2652 displays high inhibiting effects in MV4-11 and NB4 leukaemia cells. MC2652 shows antiproliferative activity against prostate cancer LNCaP cells.
TACH101 (QC8222, TACH 101) is a reversible, α-ketoglutarate competitive, selective and potent inhibitor of KDM4 isoforms A-D with IC50 values of <0.1 uM against all four isoforms.TACH101 demonstrated potent increase of H3K36me3 levels (EC50 <0.001 uM, HTRF) in KYSE-150 cell line engineered to overexpress KDM4C and showed potent anti-proliferative activity in multiple cell lines in OncoPanel.Sub-micromolar levels of TACH101 induced apoptosis in human colorectal (HT-29), esophageal (KYSE-150), and triple negative breast cancer (MDA-MB-231) cell lines with EC50s of 0.033-0.092 uM.TACH101 triggered effective tumor growth control in xenograft models including colorectal, esophageal, gastric, breast, and lymphoma with tumor growth inhibition of up to 100%.
Bomedemstat (IMG-7289) ditosylate is an oral and irreversible inhibitor of the epigenetically active lysine-specific demethylase 1 (LSD1) in mouse models of myeloproliferative neoplasms (MPNs). Bomedemstat can be used for the research of acute myelogenous leukemia (AML) and myelofibrosis (MF). Antineoplastic activity.
Seclidemstat (SP-2577) mesylate is a potent noncompetitive and reversible KDM1A (LSD1) inhibitor (Ki=31 nM, IC50=13 nM). Seclidemstat mesylate promotes antitumor immunity in switch/sucrose nonfermentable (SWI/SNF) complex mutated ovarian cancer, as well as inhibit virus production, viral DNA replication, and late gene expression. Seclidemstat mesylate can be used for the research of Ewing Sarcoma.
Pulrodemstat (CC-90011) is a potent, selective, reversible and orally active inhibitor of lysine specific demethylase-1 (LSD1) with an IC50 of 0.25 nM. Pulrodemstat is less enzymatic inhibition against LSD2, MOA-A, and MAO-B. Pulrodemstat induces acute myeloid leukemia (AML) and small cell lung cancer (SCLC) cells differentiation and has potent anticancer activity.
PFI-90 is a selective inhibitor of the histone demethylase KDM3B. PFI-90 induces apoptosis and cell differentiation resulting in delayed tumor progression in vivo.
