In Vitro

ALK5-IN-79 (1000 nM; 2 h) has strong-to oderate inhibitory activities against ALK5, SRC, LCK, BRAF (V600E), RET, PDGFRα, EGFR and KDR at 1000 nM (inhibitory rate >20%) [1].
ALK5-IN-79 (0, 0.125, 0.25, 0.5, 1.0 and 2.0 μM; 1 h) inhibits the phosphorylation of smad 3, at a dose-dependent pattern[1].

Western Blot Analysis[1]

Cell Line: Abnormal proliferation of cancer associated fibroblasts
Concentration: 0-2.0 μM
Incubation Time: 1 h
Result: ALK5-IN-79 blocked the TGF-β1 induced upregulation of collagen I (Col1) and α-SMA at mRNA and protein levels, i.e., the targeted genes of samd 3. ALK5-IN-79 led to the reduced secretion of Col 1.
In Vivo

ALK5-IN-79 (300 mg/kg/day; ip; every day for 7 days) decreases the weight of the mice. ALK5-IN-79 is safe in vivo[1].
ALK5-IN-79 (10 and 50 mg/kg/day; iv; every other day for 24 days) resultes in tumor growth inhibition (TGI) rates of 61.9% and 80.5% in the Syngeneic Model, ALK5-IN-79 (10 and 50 mg/kg/day; iv; every other day for 24 days) resultes in tumor growth inhibition (TGI) rates of 62.1% and 75.6% in the PANC-1 subcutaneous xenograft model. ALK5-IN-79 inhibites pancreatic cancer tumor growth in a metrology-dependent manner[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.
