Biological Activity

Description T-3775440 HCl is an irreversible LSD1 inhibitor that is highly selective for LSD1 relative to other monoamine oxidases (e.g., MAO-A and MAO-B), with an IC50 value of 2.1 nmol/L.
Targets
LSD1 [1]
2.1 nM
In vitro

T-3775440 treatment enforces transdifferentiation of erythroid/megakaryocytic lineages into granulomonocytic-like lineage cells. T-3775440 disrupts the interaction between LSD1 and growth factor-independent 1B (GFI1B), a transcription factor critical for the differentiation processes of erythroid and megakaryocytic lineage cells. 48-hour T-3775440 treatment induces cell-cycle arrest and apoptosis in AEL (TF-1a, HEL92.1.7) and AMKL cell lines (CMK11-5, M07e). T-3775440 treatment increases the G1 and sub-G1 phase populations in TF-1a and CMK11-5 cells[1].

In vivo

T-3775440 exerts tumor growth suppression in in vivo mouse xenograft models of AML. In mice, T-3775440 treatment results in a transient reduction in platelets, followed by a significant rebound. There is no obvious effect on red blood cell counts following a single administration. T-3775440 also exhibits potent antitumor effects in an additional AEL model of HEL 92.1.7 and an AMKL model of CMK11-5, possessing profound anti-AEL and anti-AMKL activity[1].

Protocol (from reference)

Cell Research:

[1]

  • Cell lines: TF-1a and CMK11-5 cells
  • Concentrations: 0, 10, 50 nM (TF-1a cells); 0, 20, 100 nM (CMK11-5 cells)
  • Incubation Time: 24 and 48 h
  • Method:

    TF-1a and CMK11-5 cells are treated with the indicated concentration of T-3775440 for 24 or 48 hours. Treated cells are subsequently harvested and lysed to prepare total lysates. Immunoblotting analyses are performed to determine the expression levels of p27, cleaved PARP, and β-actin in the cell lysates.

Animal Research:

[2]

  • Animal Models: Female C.B17/Icr-scid/scid Jcl mice subcutaneously (s.c.) inoculated in the flank with AML cells
  • Dosages: 15-20 mg/kg
  • Administration: oral

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
