Uses
Divarasib (GDC-6036) is an orally bioavailable, highly potent, and selective KRAS G12C inhibitor with an IC50 of <0.01 μM. Divarasib covalently binds to the switch II (SW-II) pocket of KRAS G12C and irreversibly locks it in the inactive GDP-bound state.
in vivo
Divarasib (10-100 mg/kg/day; PO for 7 days) decreases the ratio of free KRAS G12C[1].
| Animal Model: | Female C.B-17 SCID (Inbred) mice (20-21 weeks old; 24.1 g) with human NSCLC NCI-H2030.X1.1 cells[1] |
| Dosage: | 10, 25, or 100 mg/kg |
| Administration: | Oral gavage (PO) every day (QD) for 7 days (vehicle: 0.5% methylcellulose) |
| Result: | Decreased the ratio of free KRAS G12C to internal standard. Dose-dependent target engagement was observed for all time points (2, 8, and 24 h post-last dose), with over 90% KRAS G12C engagement observed for the highest dose 100 mg/kg assessed. |
IC 50
K-Ras(G12C): <0.01 μM (IC50)
