    生物活性

    Mirdametinib (PD0325901) is an orally active, selective and non-ATP-competitive MEK inhibitor with an IC50 of 0.33 nM. Mirdametinib exhibits a Kiapp of 1 nM against activated MEK1 and MEK2. Mirdametinib suppresses the expression of p-ERK1/2 and induces apoptosis. Mirdametinib has anti-cancer activity for a broad spectrum of human tumor xenografts[1][2][3].

    Mirdametinib (PD325901; 0.0064, 0.032, 0.16, 0.8, 4, 20, 100 nM; for 2 days) inhibits the growth of Papillary thyroid carcinomas (PTC) cell lines (TPC-1 cells and K2 cells) with GC50 of 11 nM and 6.3 nM, respectively[3].
    Mirdametinib (100 nmol/L; for 4 days) induces apoptosis in K2 cells (top) or TPC-1 cells[3].
    Mirdametinib (0.1, 1, 10, 100, 1000 nM; for 1 hour) suppresses the expression of p-ERK1/2 in K2 cells (top) or TPC-1 cells[3].
    Mirdametinib prevents the growth of melanoma cell lines. Mirdametinib significantly prevents the the growth of PTC cells harboring a BRAF mutation at very low concentration (10 nM)[3].

    体内研究
    (In Vivo)

    Mirdametinib (25 mg/kg, p.o.) inhibits phosphorylation of ERK by more than 50% at 24 hours post-dosing. Mirdametinib (25 mg/kg/day; po) produces a 70% incidence of complete tumor responses (C26 model)[2].
    Mirdametinib (20-25 mg/kg/day; oral gavage; for 3 weeks (5 consecutive days/week)) suppresses tumor growth completely in mice inoculated with PTC cells carrying a BRAF mutation (K2) and significantly decreased tumor growth in mice inoculated with PTC cells carrying the RET/PTC1 rearrangement (TPC-1) in athymic Ncr-nu/nu mice at ages 6 to 8 weeks[3].

    Kinase Assay
    [1]

    Incorporation of 32P into myelin basic protein (MBP) is assayed in the presence of a glutathione S-transferase fusion protein containing p44MAP kinase (GST-MAPK) and a glutathione S-transferase protein containing p45MEK (GST-MEK). The assay solution contained 20 mM HEPES, pH 7.4, 10 mM MgCl2, 1 mM MnCl2, 1 mM EGTA, 50 mM [gamma-32P]ATP, 10 mg GST-MEK, 0.5 mg GST-MAPK and 40 mg MBP in a final volume of 100 mL. Reactions are stopped after 20 minutes by addition of trichloroacetic acid and filtered through a GF/C filter mat. 32P retained on the filter mat is determined using a 1205 Betaplate. PD0325901 is assessed at various dose ranges in order to determine dose response curves.

    Cell Assay
    [2]

    PTC cells (1×104) are seeded in 24-well plates with 1 mL of medium for 4 days in a 37°C incubator. MEK inhibitor PD0325901 at varying concentrations is added to the cells in triplicate on day 0. MTT dissolved in 0.8% NaCl solution at 5 mg/mL is added to each well (0.2 mL) on day 2 to test GC50 or every day for cell growth curves. The cells are incubated at 37°C for 3 hours with MTT. The liquid is then aspirated from the wells and discarded. Stained cells are dissolved in 0.5 mL of DMSO and their absorption at 570 nm is measured using a Synergy HT multidetection microplate reader. For GC50, cell growth is calculated as 100×(T−T0)/(C−T0), where T is the optical density of the wells treated with inhibitors after a 48-hour period, T0 is the optical density at time zero, and C is the control optical density with DMSO only.

    Animal Administration
    [2]

    Mice (10-14 per group) are anesthetized s.c. with a cocktail. K2 and TPC-1 cells stably infected with a retrovirus expressing luciferase (5×105 cells in 5 μL RPMI1640 medium) are inoculated into the thyroid gland, and the mice are monitored weekly for tumor growth by Xenogen using Living Image 3.0 software. One week after inoculation, PD0325901 is dissolved in 80 mM citric buffer (pH 7) by sonication and given to mice daily by oral gavage (20-25 mg/kg) for 3 weeks (5 consecutive days/week). Mice are sacrificed only due to tumor burden or loss of 20% of body weight. Tumor sizes are measured with calipers and tumor volume (V) is calculated by the formula (V=length×width×depth). Control mice are given 80 mM citric buffer (pH 7) alone. All in vivo experiments are done at least twice.
