Biological Activity

Kobe2602 is a novel and effective small-molecule compound inhibiting Ras–Raf interaction by SBDD. Kobe2602 at 20 μM efficiently inhibited the phosphorylation of MEK and ERK, downstream kinases of Raf in NIH 3T3 cells transiently expressing H-Ras G12V. Moreover, Kobe2602 exhibits antitumor activity on a xenograft of human colon carcinoma SW480 cells carrying the K-ras(G12V) gene by oral administration.

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.

Related Ras Products

BBO-8520 is a first-in-class orally active covalent KRAS G12C inhibitor. BBO-8520 inhibits KRASG12C (ON) by locking the GTP-binding protein in state 1, a conformation incapable of binding effectors, thereby inhibiting the downstream signaling of KRASG12C (ON) that promotes cell proliferation. BBO-8520 also rapidly and completely blocks the RAS-RAF1 interaction, returning KRASG12C to its inactive (OFF) state.


RMC-9805 (KRAS G12D inhibitor 18) is an orally active KRAS G12D inhibitor. RMC-9805 (KRAS G12D inhibitor 18) inhibits RAS signaling and induces apoptosis in KRAS G12D mutant cancer cells.


RMC-7977 is a highly selective, reversible, tri-complex RAS inhibitor of the active (GTP-bound) forms of KRAS, HRAS, and NRAS, with affinity for both mutant and wild type (WT) variants. RMC-7977 demonstrated potent activity against RAS-addicted tumours carrying various RAS genotypes, particularly against cancer models with KRAS codon 12 mutations (KRASG12X).


KRpep-2d is a potent K-Ras inhibitor and inhibits proliferation of K-Ras-driven cancer cells.
