Biological Activity

Compound E is a cell-permeable, potent, selective inhibitor of γ-secretase and Notch processing. Compound E bloks β-amyloid(40), β-amyloid(42), and Notch γ-secretase cleavage with IC50s of 0.24, 0.37, 0.32 nM, respectively. Compound E reduces the proliferation of T47D, and MCF-7 cell lines by less than 50% at a concentration of 50 μM.

Chemical Information
Molecular Weight 490.51
Formula C27H24F2N4O3
CAS Number 209986-17-4
Solubility (25°C) DMSO 90 mg/mL
Storage -20°C, protect from light, dry, sealed
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.
