ZINC69391, a specific Rac1 inhibitor, interferes with Rac1-GEF interaction by masking Trp56 residue on Rac1 surface. ZINC69391 interferes with the interaction of Rac1 with Dock180 and reduces Rac1-GTP levels. ZINC69391 induces apoptosis, and shows antiproliferative and antimetastatic effects.

| 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.

| BBO-8520
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
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
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). |
