體內(nèi)研究
(In Vivo)

CCT245737 (150 mg/kg p.o.) inhibits tumor growth in combination with LY 188011 (100 mg/kg iv) in HT29 colon cancer xenografts. CCT245737 (300 mg/kg, p.o.) also inhibits the LY 188011 (60 mg/kg iv) induced pSer296 CHK1 autophosphorylation at 24 h in SW620 human colon cancer xenografts[1]. CCT245737 (150 mg/kg, p.o) alone significantly inhibits tumor growth in an Eμ-Myc mouse model of human B-cell lymphocytic leukemia[2].

Cell Assay
[2]

Cytotoxicity is determined as the drug concentration that gives 50% inhibition of tumor cell proliferation (GI50) using a 96 h Sulforhodamine B (SRB) assay. Inhibition of intracellular CHK1 activity is measured using a cell based ELISA for the abrogation of an VP-16 induced G2 checkpoint (mitosis induction assay, MIA). The IC50 for G2 checkpoint abrogation (MIA) is determined in the presence of nocodazole using UCN01 as a positive control. The activity index (AI) is used as a measure of the compounds ability to induce mitosis relative to its toxicity (i.e., ratio of MIA IC50: 96 h SRB GI50). Routine potentiation studies are carried out using a fixed concentration (GI50) of either LY 188011 or SN38 in combination with a range of CCT245737 concentrations to determine the combination GI50 of CCT245737. The ability of CCT245737 to enhance LY 188011 or SN38 cell killing is expressed as a potentiation index (PI) equal to the ratio of the GI50 for CCT245737 alone versus the combination GI50 for CCT245737. PI values > 1 indicate potentiation of the genotoxic activity. In addition, a series of experiments is carried out using fixed, non- or minimally toxic concentrations of CCT245737 (≤GI20) with a range of different concentrations of LY 188011 or SN38 to determine the extent to which CCT245737 enhances drug cytotoxicity compared with the genotoxic agent alone, i.e. conventional PI (ratio GI50 genotoxic alone: GI50 genotoxic combined with non-toxic CCT245737 concentration, Con PI)[2].

Animal Administration
[1]

Human HT29 colorectal carcinoma cells are injected s.c into the flanks of female NCr athymic mice 6-8 weeks of age. Dosing commenced 5 days after transplantation when tumors reach a mean diameter of 5.5 mm. LY 188011 (100 mg/kg i.v.) is dosed in saline on days 0, 7 and 14 and compounds 4 (CCT245737) and 41 (150 mg/kg p.o.) in 10% DMSO 20% PEG 400, 5% Tween 80, 65% water, 24 and 48 h after each dose of LY 188011. Tumors are measured and body weights recorded three times weekly. Animals are culled on an individual basis when tumors reach a predetermined humane endpoint (mean diameter <15 mm)[1].

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.
