1309444-75-4性质、用途与生产工艺

  • 生物活性 K145 是一种选择性的,具有底物竞争性和口服活性的 SphK2 抑制剂,IC50 为 4.3 µM,Ki 为 6.4 µM。K145 对 SphK1 和其他蛋白激酶没有活性。K145 可诱导细胞凋亡,并具有强大的抗肿瘤活性。
  • 靶点

    IC50: 4.3 µM (SphK2)
    Ki: 6.4 µM (SphK2)

  • 体外研究

    K145 (0-10 µM; 24-72 hours; U937 cells) treatment significantly inhibits the growth of U937 cells in a concentration-dependent manner.
    K145 (10 µM; 24 hours; U937 cells) treatment significantly induces apoptosis in U937 cells.
    K145 (4-8 µM; 3 hours; U937 cells) treatment decreases the phosphorylation of ERK and Akt.
    Treatment with K145 (10 µM) causes a decrease of total cellular S1P without significant effects on ceramide levels.

    Cell Viability Assay

    Cell Line: U937 cells
    Concentration: 0 µM, 4 µM, 6 µM, 8 µM, 10 µM
    Incubation Time: 24 hours, 48 hours, 72 hours
    Result: Significantly inhibited the growth of U937 cells in a concentration-dependent manner.

    Apoptosis Analysis

    Cell Line: U937 cells
    Concentration: 10 µM
    Incubation Time: 24 hours
    Result: Significantly induced apoptosis in U937 cells.

    Western Blot Analysis

    Cell Line: U937 cells
    Concentration: 4 µM, 8 µM
    Incubation Time: 3 hours
    Result: Phosphorylated ERK and Akt were decreased.
  • 体内研究

    K145 (50 mg/kg; oral gavage; daily; for 15 days; BALB/c-nu mice) treatment significantly inhibits the growth of U937 tumors in nude mice.

    Animal Model: BALB/c-nu mice injected with U937 cells
    Dosage: 50 mg/kg
    Administration: Oral gavage; daily; for 15 days
    Result: Oral gavage; daily; for 15 daysInhibited the growth of U937 tumors at 50 mg/kg dose and no apparent toxicity was observed.
