Biological Activity

RBN-2397 is a potent and orally active NAD+ competitive inhibitor of PARP7 (IC50<3 nM). RBN-2397 selectively binds to PARP7 (Kd=0.001 μM) and restores interferon (Type I) signaling. RBN-2397 (0.0001-100 μM; 24 hours) inhibits cells proliferation with an IC50 value of 20 nM in NCI-H1373 lung cancer cells. 

RBN-2397 (3-100 mg/kg; oral; once daily) 24-32 days treatment induces tumor-specific adaptive immune memory in CT26 syngeneic model with durable complete responses in CT26 tumor-bearing BALB/c mice.

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.

Fluzoparib (SHR3162)

Fluzoparib (SHR3162) is an effective oral active PARP1 inhibitor (IC50=1.46±0.72 nM) with superior antitumor activity. Fluzoparib selectively inhibited the proliferation of homologous recombination repair (HR) deficient cells and sensitized HR deficient cells to cytotoxic drugs. Fluzoparib has good pharmacokinetic properties in vivo and can be used in cancer research.
