Embodiment 3
[0076] Embodiment 3 in vitro experiments
[0077] Test drug:
[0078] 1-[[[4-(4-fluoro-2-methyl-1H-indol-5-yl)oxy-6-methoxyquinolin-7-yl]oxy]methyl]cyclopropylamine di Hydrochloride (referred to as the dihydrochloride of compound I); vincristine; doxorubicin; cyclophosphamide.
[0079] 1. The effect of dihydrochloride of compound I on inhibiting the growth of giant cell tumor of bone
[0080] Preparation method:
[0081] The dihydrochloride of compound I was made into the required concentration with distilled water;
[0082] Experimental animal preparation:
[0083] BALB / cA-nude nude mice, feeding environment: SPF grade. Nude mice were subcutaneously inoculated with human giant cell tumor cells of bone (source of giant cell tumor of bone: primary human GCT cells isolated from tumor tissues of confirmed patients. For the isolation method of GCT stromal cells, refer to the method provided by Smink et al.), wait until the tumor grows to 100-250mm 3 Afterwards, the animals ...
