    Description

    A 83-01 is a potent inhibitor of TGF-β type I receptor ALK5 kinase, type I nodal receptor ALK4 and type I nodal receptor ALK7, with IC50s of 12, 45 and 7.5 nM against the transcription induced by ALK5, ALK4 and ALK7, respectively.

    IC50 & Target

    IC50: 12 nM (ALK5, cell-based), 45 nM (ALK4 cell-based), 7.5 nM (ALK7 cell-based)[1]

    In Vitro

    A 83-01 is a potent inhibitor of TGF-β type I receptor ALK5 kinase, ALK4 and ALK7, reduces the level of ALK-5-induced transcription with an IC50 of 12 nM in Mv1Lu cells, also blocks the ALK4-TD and ALK7-TD induced transcription with IC50s of 45 nM and 7.5 nM in R4-2 cells, and weakly suppresses that induced by constitutively active ALK-6, ALK-2, ALK-3, and ALK-1. A 83-01 (0.03-10 µM) potently prevents the growth-inhibitory effects of TGF-β, and completely inhibits the effect at 3 µM. A 83-01 (1-10 µM) inhibits TGF-β-induced Smad activation in HaCaT cells[1]. A 83-01 (1 µM) decreases cell motility, adhesion and invasion increased by TGF-β1 in HM-1 cells, but does not change cell proliferation[2].

    In Vivo

    A 83-01 (50, 150 and 500 μg/mouse, i.p.) significantly improves survival of the mice without body weight or neurobehavioral appearances[2]. A 83-01 (0.5 mg/kg, i.p.) shows a significantly strong antitumor effect in mice bearing M109 cells[3].

    Cell Assay
    [2]

    HM-1 cells are seeded into a 96-well plate and are incubated for 18 hr. A 83-01 (1 μM) or vehicle are then added for 12 hr followed by the addition of TGF-β1 (1 ng/mL) or vehicle for 60 hr. The number of viable cells in each well is examined using the WST-1 assay[2].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Administration
    [2]

    Mice[2]
    Female B6C3F1 mice used for the in vivo studies are maintained under specific pathogen-free conditions. To evaluate the effect of A 83-01 on the survival of mice bearing peritoneal dissemination, HM-1 cells (1×106) are injected into the abdominal cavity via the left flank of the mouse. Starting the next day, A 83-01 (150 μg/body) or vehicles (PBS with 0.5% DMSO) are injected into the abdominal cavity three times per week. Mice are euthanized before reaching the moribund state[2].
