TAS1440
Based on 1 Customer Validation
TAS1440 is an orally active LSD1/KDM1A inhibitor with a human IC50 of 4.8 nM. TAS1440 non-covalently binds to the histone H3-binding pocket of LSD1, inhibiting demethylase activity and disrupting repressive complexes with INSM1 and SMAD2. TAS1440 activates tumor-suppressive TGF-β and NOTCH signaling pathways via transcriptional reprogramming. TAS1440 can be used for the research of small cell lung cancer, specifically the SCLC-A subtype.

Biological Activity

KDM1/LSD1 4.8 nM (IC50) |
TAS1440 is a highly selective, histone H3-competitive inhibitor of purified recombinant human LSD1, with an IC50 of 4.8 nM and no significant activity against LSD2, MAO-A, MAO-B, or a broad panel of other epigenetic enzymes[1].
TAS1440 (0-7500 nM; 8 days) selectively inhibits proliferation of SCLC-A cell lines, with the greatest potency in NCI-H1417, NCI-H510A, NCI-H146, and COR-L51 cells, and exhibits stronger antiproliferative activity than covalent LSD1 inhibitors in these sensitive models[1].
TAS1440 (300 nM; 1-7 days) induces transcriptional reprogramming in SCLC cell lines, activating tumor-suppressive TGF-β and NOTCH pathways and suppressing neuroendocrine gene expression, with the most pronounced changes in TAS1440-sensitive SCLC-A cell lines[1].
TAS1440 (300 nM; 30 min-5 days) activates TGF-β and NOTCH signaling in SCLC-A cell lines by inducing SMAD2 phosphorylation, NOTCH1 upregulation, and nuclear accumulation of active pathway components, while also disrupting INSM1-LSD1 and SMAD2-LSD1 protein complexes more effectively than covalent LSD1 inhibitors[1].
TAS1440 (300 nM; 5 days) induces global epigenetic reprogramming in SCLC-A cell lines, increasing active histone marks (H3K4me1, H3K4me2, H3K27ac) at TSSs and promoting INSM1 and SMAD2 binding to tumor-suppressive NOTCH and TGF-β pathway gene promoters[1].
TAS1440 (100-3,000 nM; 7 days) antiproliferative and transcriptional effects in SCLC-A cell lines depend on LSD1 expression and catalytic activity, while its ability to disrupt INSM1/SMAD2-LSD1 complexes is independent of LSD1 catalytic function[1].
TAS1440 (300 nM; 2 h-10 days) requires INSM1 for its antiproliferative effects, transcriptional reprogramming, and activation of TGF-β/NOTCH signaling in SCLC-A cell lines[1].

Cell Line:19 small cell lung cancer (SCLC) cell lines stratified into SCLC-A, SCLC-N, and SCLC-P subtypes
-
Concentration:7500 nM
-
Incubation Time:8 days
-
Result:Showed the strongest growth suppression in SCLC-A cell lines compared to SCLC-N and SCLC-P subtypes.
Exhibited the lowest IC50 values in NCI-H1417, NCI-H510A, NCI-H146, and COR-L51 SCLC-A cells.
Exhibited greater potency than covalent LSD1 inhibitors in sensitive SCLC-A lines, as covalent comparators often had IC50 values ≥1,000 nM or were right-censored at the 7,500 nM testing limit.
Showed broadly similar inhibition patterns to another H3-competitive inhibitor (CC-90011) but greater potency in the most sensitive SCLC-A lines.
TAS1440 (50 mg/kg/day; p.o.; daily; 3 weeks) significantly reduces tumor growth in INSM1-wild-type but not INSM1-knockout NCI-H146 SCLC-A xenografts, demonstrating INSM1 dependence for in vivo efficacy[1].
TAS1440 (50 mg/kg/day; p.o.; daily; 4 weeks) reduces pulmonary tumor burden by 67% in an orthotopic NCI-H146 SCLC-A xenograft model[1].
