SC-514 inhibits the native IKK complex or recombinant human IKK-1/IKK-2 heterodimer with IC50s of 6.1±2.2 μM and 2.7±0.7 μM, respectively. IKK-2 inhibition by SC-514 is selective, reversible, and competitive with ATP. SC-514 inhibits transcription of NF-κB-dependent genes in IL-1β-induced rheumatoid arthritis-derived synovial fibroblasts in a dose-dependent manner. SC-514 inhibits all forms of recombinant human IKK-2 including rhIKK-2 homodimer, rhIKK-1/rhIKK-2 heterodimer, as well as the constitutively active form of rhIKK-2 with comparable IC50 values in the 3-12 μM range[1]. To evaluate whether the reactive oxygen species (ROS)-inducing IKKβ inhibitor increases the sensitivity of melanoma cells to nitrosourea. The responses of melanoma cells are first assessed to SC-514/Fotemustine co-treatment. Melanoma cell lines are treated with 50 μM of SC-514 and Fotemustine alone and in combination for 48 h and growth inhibition is assessed. Co-treatment with SC-514 significantly enhances Fotemustine-induced cytotoxicity in all melanoma cell lines tested[2].

Protocol
IKK complexes are immunoprecipitated from IL-1β-treated RASF cell lysates (0.5-2 mg) using a NEMO antibody (3-10 μg) followed by the addition of protein A-agarose beads. Antibody complexes are pelleted by centrifugation and washed 3 times with 1 mL of cold whole-cell lysis buffer followed by 2 washes in kinase buffer (25 mM HEPES, pH 7.6, 2 mM MgCl2, 2 mM MnCl2, 10 mM NaF, 5 mM DTT, and 1 mM phenylmethylsulfonyl fluoride). 100-200 μg of immunoprecipitated IKK is analyzed for kinase activity in a reaction containing 10 μM biotinylated IκBα peptide as substrate and 1 μM [γ-33P]ATP (2500 Ci/mmol). After incubation at room temperature for 30 min, 25 μL of the reaction mixture is withdrawn and added to a SAM 96 biotin capture plate. After successive wash steps the plate was allowed to air-dry, and 25 μL of scintillation fluid is added to each well. Incorporation of [γ-33P]ATP is measured using a Top-Count NXT[1].

For crystal violet staining assay, melanoma cell lines (1×104) are seeded in 60 mm dishes, and then untreated or pretreated with SC-514 (50 µM) and/or Fotemustine. Then, cells are formalin-fixed and stained with crystal violet. Cell numbers are measured as the optical density at 595 nm (OD595) of solubilized crystal violet from formalin-fixed cells. Cytotoxicity are also determined by the MTT reduction assay[2].

Rats[1]
SC-514 or vehicle (2% Me2SO in saline) is administered either by oral gavage (50 mg/kg) or intraperitoneally (10 and 50 mg/kg) to adult male Wistar rats that have been deprived of food overnight. Two hours after compound treatment, 1 mg/kg LPS (Escherichia coli) in saline is administered intraperitoneally 90 min after LPS administration; the animals are bled and serum TNFα levels analyzed by a rat-specific TNFα ELISA.
Mice[2]
Male nu/nu BALB/c mice (6 weeks old) are maintained in individual ventilated cages. A375 or G361 (5×106) cells are resuspended in 0.1 mL PBS and inoculated subcutaneously into the backs of nude mice and allowed to grow for 7 days. After that, mice are randomly assigned to 4 groups (n=6 for each group) and treated by intraperitoneal injection with 200 µL 30% PEG/5% Tween-80 solution as the vehicle control and 25 mg/kg SC-514 and/or 25 mg/kg Fotemustine daily for 13-15 consecutive days. Body weight and tumor volume are measured every 3 days. Tumor volumes are determined by a caliper and calculated. At the end of the experiment, mice are sacrificed and tumor xenografts are collected. Tumor tissues are stored at -80°C for Western blot analysis.
