    Description

    A939572 is a potent, and orally bioavailable SCD1 inhibitor with IC50 values of <4 nM and 37 nM for mSCD1 and hSCD1, respectively.

    IC50 & Target

    IC50: <4 nM (mSCD1), 37 nM (hSCD1)[1]

    In Vitro

    A939572 exhibits robust in vivo activity with dose-dependent desaturation index lowering effects[1]. A939572 is a small molecule that specifically inhibits SCD1 enzymatic activity. A939572 demonstrates a significant dose-dependent decrease in proliferation in Caki1, A498, Caki2, and ACHN at day 5 (IC50s of 65 nM, 50 nM, 65 nM, and 6 nM, respectively). In A939572 (SCDi) treated Caki1 and A498 cells, all five ER stress related genes are expressed at significantly increased levels compared to DMSO+BSA control, and this elevated expression can be blocked with the addition of OA-BSA[2].

    In Vivo

    Athymic nude (nu/nu) mice bearing A498 ccRCC xenografts are treated with A939572 (30mg/kg, p.o.) and Tem individually or in combination over the course of four weeks, and tumor volume (mm3) is recorded. A939572 and Tem monotherapy generate similar growth responses with approximately 20-30% reductions in tumor volume (vs. placebo control) being observed upon study completion, with values reaching statistical significance only within the last week of treatment. The combination group yields over a 60% decrease in tumor volume (vs. placebo control) by study completion with significant reductions recorded after approximately 1 week of treatment[2].

    Cell Assay
    [2]

    A939572 is dissolved in DMSO and stored, and then diluted with appropriate media before use[2].

    Cells are plated (0.5 or 1×105/well) in 24-well plates in triplicate. Cells are counted using a Coulter Particle Counter. Oleic acid-albumin is added to media at 5μMol. A939572 stocks are prepared in DMSO. Temsirolimus dosing is performed. Soft agar cultures are prepared by diluting 2× growth medium 1:1 in 1.5% Seaplaque®GTG® agarose, with 500 cells/plate in 60mm culture dishes. Colonies are stained with Giemsa and counted after 3wks[2]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Administration
    [2]

    A939572 is re-suspended in strawberry flavored Kool-Aid® in sterilized H2O (Mice)[2].

    Mice[2]
    A498 cells are subcutaneously implanted in athymic nu/nu mice at 1×106 cells/mouse in 50% Matrigel. Tumors reach ~50 mm3 prior to 4 wk treatment. A939572 is re-suspended in strawberry flavored Kool-Aid® in sterilized H2O (0.2 g/mL) vehicle at 30 mg/kg in a 50 μL dose. Mice are orally fed by using a syringe to administer the 50 μL dose twice daily/mouse. This modified method is found to be effective and less stressful on the mice. Temsirolimus is solubilized in 30% ethanol/saline and administered via intraperitoneal injection at 10 mg/kg in a 50 μL dose once every 72 hrs/mouse. Tumor volumes are calculated using the formula 0.5236 (L*W*H) and body weight are measured every 3 days. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
