In Vitro

GW2974 (0.5-50 μM, 3 h) has an obvious cytotoxicity appeared at 10 μM or above and inhibits cell proliferation of U87MG and U251MG cells at 0.5-5 μM after 24 h treatment[1].
GW2974 (0.5-5 μM, 24 h) has a dose-related role in GBM cell invasion and migration[1].
GW2974 (0.001-100 μM, 24 h) inhibits BT474, HN5, N87 cells growth[2].

In Vivo

GW2974 (30 mg/kg, 100 mg/kg for Oral gavage, once a day) inhibits GBM growth, invasion, and angiogenesis in dose of 30 mg/kg but abrogated the inhibitory effect of low-dose GW2974 on tumor invasion in dose of 100 mg/kg in GBM xenograft mice model[1].
GW2974 (10 mg/kg, 30 mg/kg, Oral gavage, twice a day) inhibits the growth of tumor in CD-1 nude mice (HN5) and C.B-17 SCID mice (BT474) models in a dosed dependent manner[2].

Animal Model: GBM xenograft mice model[1]
Dosage: 30 mg/kg, 100 mg/kg
Administration: Oral gavage (p.o.)
Result: Decelerated tumor growth at dose of 30 mg/kg and 100 mg/kg.
Inhibited the invasion to peritumor areas of tumors in 30 mg/kg group but augmented tumor invasion in 100 mg/kg group of brain tissues.
Inhibited angiogenesis in doses of 30 mg/kg and 100 mg/kg.
Animal Model: CD-1 nude mice (HN5), C.B-17 SCID mice (BT474)[2]
Dosage: 10 mg/kg, 30 mg/kg

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.
