SC144 hydrochloride is a first-in-class, orally active gp130 (IL6-beta) inhibitor. SC144 hydrochloride binds gp130, induces gp130 phosphorylation (S782) and deglycosylation, abrogates Stat3 phosphorylation and nuclear translocation, and further inhibits the expression of downstream target genes. SC144 hydrochloride shows potent inhibition of gp130 ligand-triggered signaling. SC144 hydrochloride induces apoptosis in human ovarian cancer cells.

    Description

    SC144 hydrochloride is a first-in-class, orally active gp130 (IL6-beta) inhibitor. SC144 hydrochloride binds gp130, induces gp130 phosphorylation (S782) and deglycosylation, abrogates Stat3 phosphorylation and nuclear translocation, and further inhibits the expression of downstream target genes. SC144 hydrochloride shows potent inhibition of gp130 ligand-triggered signaling. SC144 hydrochloride induces apoptosis in human ovarian cancer cells[1].

    IC50 & Target[1]

    IL6-beta

     

    In Vitro

    SC144 inhibits cell growth in a panel of human ovarian cancer cell lines with IC50s in a submicromolar range (IC50=OVCAR-8, OVCAR-5, OVCAR-3= 0.72, 0.49, 0.95 μM)[1].
    The potency of SC144 toward NCI/ADR-RES (Paclitaxel- and Doxorubicin-resistant, IC50=0.43 μM) and HEY (Cisplatin-resistant, IC50=0.88 μM) suggests an ability to overcome drug resistance in ovarian cancer[1].
    SC144 (2 μM; 24 hours) causes significantly more apoptosis in OVCAR-8 and Caov-3 than normal kidney epithelial and normal endometrial cells[1].
    SC144 (0.5-2 μM; 0-6 hours) substantially increases the phosphorylation of gp130 (S782) in both OVCAR-8 and Caov-3 cells in a time- and dose-dependent manner[1].
    SC144 is cytotoxic to ovarian cancer cells via a mechanism involving the inhibition of gp130 activity, leading to the inactivation of Akt and Stat3 as well as the suppression of Stat3-regulated gene expression. As are result, SC144 treatment eventually causes cell-cycle arrest, anti-angiogenesis, and apoptosis[1].

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    90% Corn Oil

      Solubility: ≥ 1 mg/mL (2.79 mM); Clear solution

      This protocol yields a clear solution of ≥ 1 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 mg/mL) to 900 μL Corn oil, and mix evenly.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
