Taking the 1 mL working solution as an example, add 50 μL of 200 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to make it clear; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	Lenalidomide is a TNF-α secretion inhibitor with IC50 of 13 nM in PBMCs. Lenalidomide (CC-5013) is a ligand of ubiquitin E3 ligase cereblon (CRBN), and it causes selective ubiquitination and degradation of two lymphoid transcription factors, IKZF1 and IKZF3, by the CRBN-CRL4 ubiquitin ligase. Lenalidomide promotes cleaved caspase-3 expression and inhibit VEGF expression and induces apoptosis.
in vitro	Lenalidomide strongly induces IL-2 and sIL-2R production. Lenalidomide-induced tyrosine phosphorylation of CD28 on T cells is followed by a down-stream activation of NF-κB. ^[2] Lenalidomide and pomalidomide inhibits autoubiquitination of CRBN in HEK293 T cells expressing thalidomide-binding competent wild-type CRBN, but not thalidomide-binding defective CRBN(YW/AA). Overexpression of CRBN wild-type protein, but not CRBN(YW/AA) mutant protein, in KMS12 myeloma cells, amplifies pomalidomide-mediated reductions in c-myc and IRF4 expression and increases in p21(WAF-1) expression. Long-term selection for Lenalidomide resistance in H929 myeloma cell lines is accompanied by a reduction in CRBN, while in DF15R myeloma cells resistant to both pomalidomide and Lenalidomide, CRBN protein is undetectable. ^[3] Lenalidomide prevents induction of defects by down-regulating tumor cell inhibitory molecule expression. Lenalidomide prevents induction of tumor-induced T cell lytic synapse dysfunction. Lenalidomide treatment blocks CLL cell-induced T cell actin synapse dysfunction, mimicks antibody blockade, and down-regulates expression of CLL inhibitory ligands and their receptors on T cells. Lenalidomide treatment prevents tumor-induced immune suppression in FL, DLBCL, HL, MM, SCC, and OC and down-regulates immunosuppressive ligand expression on all tumor cells examined. CTL killing function significantly increases following antibody blockade of CLL inhibitory ligands or Lenalidomide treatment compared to control treatments. Treatment of autologous CLL-T cell co-cultures with Lenalidomide reverses impaired CD8⁺ T cell lytic synapse formation and granzyme B trafficking. ^[4]
in vivo	The induction of angiogenesis by bFGF is significantly inhibited by oral treatment of Lenalidomide in a dose-dependent manner. Lenalidomide significantly decreases the percentage of vascularized area from 5.16% (control group) to 2.58% (50 mg/kg). Lenalidomide significantly reduces the calculated total MVL from 21.07 (control) to 8.11 (50 mg/kg). Lenalidomide significantly inhibites HUVEC migration through the fibronectin-coated membranes towards 0.1 ng/mL of bFGF at 100 μM, 1 ng/mL of VEGF at concentrations of 10 μM and 100 μM. ^[5]

キナーゼアッセイ	Assay for inhibition of TNF synthesis by human PBMCs
キナーゼアッセイ	Human PBMCs from normal donors are obtained by Ficoll−Hypaque density centrifugation. Cells (10⁶ cells/mL) are cultured in RPMI supplemented with 10 AB+ serum, 2 mM l-glutamine, 100 U/mL penicillin, and 100 μg/mL streptomycin. Lenalidomide is dissolved in DMSO at 20 mg/mL; further dilution is done with culture medium. The final DMSO concentration in all assays including the controls is 0.25%. Lenalidomide is added to cells 1 hour prior to the addition of LPS. PBMCs (10⁶ cells/mL) are stimulated with 1 μg/mL of LPS from Salmonella minnesota R595. Cells, in triplicate, are incubated with LPS for 18−20 hours at 37 °C in 5% CO₂. Supernatants are then harvested and assayed for cytokine levels. In some experiments, supernatants are kept frozen at −70 °C until use. Cell viability is assayed by Trypan blue exclusion dye method. The concentration of TNFα in the culture supernatants is determined by ELISA. Lenalidomide is assayed in a minimum of three separate experiments. Percent inhibition is determined as 100 × [1 − (cytokine(experimental)/cytokine(control))].
