Biological Activity

PPNDS tetrasodium is a selective and competitive meprin β inhibitor (IC50: 80 nM, Ki: 8 nM), and also inhibits ADAM10 (IC50: 1.2 μM). PPNDS tetrasodium is also a P2X1 receptor antagonist. PPNDS is an agonist for the ATP receptor of Paramecium. PPNDS tetrasodium potently inhibits polymerases from viruses. PPNDS tetrasodium can be used in the research of infection and cancers.

Chemical Information
Molecular Weight 694.36
Formula C18H11N4Na4O14PS2
CAS Number 1021868-77-8
Form Solid
Solubility (25°C) Water 37.5 mg/mL (ultrasonic and warming and heat to 60°C)
Storage -20°C, 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.
