Biological Activity

Dryocrassin ABBA (Dryocrassin) is a natural product of flavonoids extracted from Sophora flavescens, with antiviral and antibacterial activities. Dryocrassin ABBA has antiviral activity against H5N1 avian influenza virus. Dryocrassin ABBA could inhibit coagulase activity of STaphylococcus aureus vWbp. Dryocrassin ABBA can inhibit the immune stimulation of dendritic cells and prolong the survival rate of allografts.

Chemical Information
Molecular Weight 820.83
Formula C43H48O16
CAS Number 12777-70-7
Form Solid
Solubility (25°C) DMSO ≥ 10 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.
