Biological Activity

NT157, a selective inhibitor of IRS-1/2(insulin receptor substrate), has the potential to inhibit IGF-1R and STAT3 signaling pathways in cancer cells and stroma cells of TME leading to a decrease in cancer cell survival.

Chemical Information

Formula C16H14BrNO5S
CAS Number 1384426-12-3
Solubility (25°C) DMSO 82 mg/mL
Storage Powder          -20°C   3 years ;  4°C   2 years
In solvent       -80°C   6 months ;  -20°C   1 month
Conversion of different model animals based on BSA (PMID: 27057123)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 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 Compound A of 10 mg/kg.

IGF-I (24-41)

IGF-I (24-41) (Insulin-like Growth Factor I (24-41)) is amino acids 24 to 41 fragment of IGF-I.

GIP, human

GIP, human is a peptide hormone consisting of 42 amino acids that also acts as a promoter of glucose-dependent insulin secretion and a weak inhibitor of gastric acid secretion. In addition, GIP, human acts as an enteric proinsulin hormone released by intestinal K cells in response to nutrient intake.

VMB-100

VMB-100 is an engineered mRNA molecule encoding human insulin-like growth factor-1 (IGF-1) that induces IGF-1 expression in human muscle cells.

NBI-31772 hydrate 

NBI-31772 hydrate is a potent inhibitor of interaction between insulin-like growth factor (IGF) and IGF-binding proteins (IGFBPs). NBI-31772 hydrate is also a nonpeptide ligand that releases bioactive IGF-I from the IGF-I/IGFBP-3 complex (Kis=1-24 nM for all six human subtypes). Anxiolytic and antidepressant-like effects.

AZ12253801 

AZ12253801 is an ATP-competitive IGF-1R tyrosine kinase inhibitor that shows ∼10-fold selectivity over the insulin receptor. AZ12253801 inhibits IGF-1R–driven proliferation in 3T3 mouse fibroblasts (transfected with human IGF-1R) with an IC50 of 17 nmol/L. The IC50 for epidermal growth factor receptor (EGFR)–driven proliferation is 440 nmol/L. Anti-tumor activity.
