体外研究

SKI II inhibits cell proliferation by suppressing the Wnt/β-catenin signaling pathway.SKI II promotes the degradation of βcatenin by enhancing Wnt5A.SKI II (1.25μM,48h) in combination with DDP has a clear synergistic effect in human gastric carcinoma SGC7901/DDP cell line.

Cell Cytotoxicity Assay

Cell Line:

The human gastric carcinoma SGC7901/DDP cell line.

Concentration:

0μM,1.25μM (combined with DDP).

Incubation Time:

48 hours.

Result:

SKI II in combination with DDP had a greater effect on the SGC-7901/DDP cells compared with DDP or SKI II alone.

体内研究

Chronic SKI II (50.0mg/kg,3-weekly i.p.for 16 weeks) administration leads to permanent reduction of S1P concentrations in plasma in mice.SKI II (50.0mg/kg,IP;100mg/kg,PO) treatment reduces tumor growth in mice bearing solid tumor model.

Animal Model:

8 week-old female LDL-R-/-mice.

Dosage:

50.0mg/kg.

Administration:

IP injection daily,3 days a week for 16 weeks.

Result:

A single administration of produced a significant reduction of plasma S1P with themaximum (~40%) observed 12h after injection.At sacrifice (72h after last injection) S1P levels were 266±18ng/mL and 328±30ng/mL in the SKI-II-treated and control groups,respectively.

 

Animal Model:

BALB/c mouse solid tumor model that uses JC mammary adenocarcinoma cells.

Dosage:

50.0mg/kg.

Administration:

IP injection daily,3 days a week for 16 weeks.

Result:

Had strong inhibition of tumor growth from the start of treatment of 65%,with no toxicity or weight loss.

 

Animal Model:

BALB/c JC tumor model.

Dosage:

100mg/kg.

Administration:

PO every other day.

Result:

Caused significant antitumor activity in well-established tumors as early as day 5,with maximal response seen at the end of the study. Showed 79% inhibition of tumor growth from the start of treatment.
