Biological Activity

HS-1371 inhibits ATP binding to prevent RIP3 enzymatic activity. HS-1371 shows an inhibitory effect on S227 auto-phosphorylation of RIP3 at the basal level. Inhibition of RIP3 kinase activity by HS-1371 blocks necrosome complex formation, showing disruption of MLKL recruitment. HS-1371 rescues cells from TNF-induced necroptosis.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
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.
