In vitro: SH5-07 blocks STAT3 DNA binding activity in vitro and in human glioma, breast, and prostate cancer cells and in v-Src-transformed murine fibroblasts. STAT3-dependent gene transcription is blocked along with Bcl-2, Bcl-xL, Mcl-1, Cyclin D1, c-Myc and Survivin expression. In vivo: In mouse xenograft models of glioma and breast cancer, administration of SH5-07 effectively inhibits tumor growth.
|Cell lines||Normal mouse fibroblasts (NIH3T3)|
|Preparation method||Cells are treated with 0-8 μM agent for 24-48 h. For cell cycle profile analysis, cells are harvested and fixed with 70% ice-cold ethanol and stained with propidium iodide (PI). For apoptosis analysis, cells are collected and stained with FITC-Annexin V using Apoptosis Detection Kit. Both the DNA content of cells and the Annexin V-positive cells are analyzed by FACScan flow cytometer. Cell cycle phase distribution is analyzed using the Cell-Fit program. Data acquisition is gated to exclude cell doublets.|
|Incubation time||24-48 h|
|Animal models||female athymic nude mice|
|Dosages||3, 5 or 6 mg/kg|
|Administration||oral gavage/tail vein injection|
|Body Surface Area (m2)||0.007||0.025||0.15||0.05||0.02||0.5|
|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|
|Animal A Km|
For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
|Solubility||100 mg/mL in DMSO|
