HLM006474

HLM006474 is a small molecule pan-E2F inhibitor that inhibits DNA binding to E2F4 with IC50 of 29.8 µM in A375 cells. HLM006474 induces a reduction in cell proliferation and an increase in apoptosis. The CDK/Rb/E2F pathway is commonly disrupted in lung cancer, and HLM006474 is shown to have efficacy in lung cancer.

Treatment of multiple cell lines with HLM006474 results in the loss of intracellular E2F4 DNA-binding activity within hours. Overnight exposure to HLM006474 results in down regulation of total E2F4 protein as well as known E2F targets. The effects of HLM006474 treatment on different cell lines varies, but includes a reduction in cell proliferation and an increase in apoptosis.[1] HLM006474 reduces the viability of both SCLC and NSCLC lines with a biological IC50 that varies between 15 and 75 mM, but with no significant difference between the groups.[2]

Concentrations 0-100 μM
Incubation Time 0-24 h
Method

Human A375 melanocytes are treated for 9-hrs with the indicated concentration of HLM006474. A375 cells are treated with 40 μM HLM006474 and EMSA and Western analyses performs at the indicated time intervals.

HLM006474 inhibits E2F4 DNA-binding and activity in vivo. In vivo HLM006474 leads to significant downregulation of E2F4 protein.[1] Short exposure of Chx10Cre;Rbf/f;p107−/− embryos to HLM006474 has a dramatic effect on tumorigenesis. Thus, modest and temporary pharmaceutical E2f inhibition blocks retinoblastoma initiation.[3]

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.
