RBC8 is a specific GTPases RalA/RalB inhibitor by inhibiting the binding of Ral to its effector RALBP1, no inhibition on the GTPases RhoA and Ras.

RMC-6291 is an orally active, covalent inhibitor of KRAS G12C (ON) that forms a tri-complex within tumor cells between KRAS G12C (ON) and cyclophilin A (CypA), thereby preventing KRAS G12C (ON) from signaling via steric blockade of RAS effector binding and eliciting deep and durable suppression of RAS pathway activity in KRAS G12C tumor models [1].

KRAS inhibitor-9 (DUN09716) is a potent KRAS inhibitor with Kd of 92 μM that blocks the formation of GTP-KRAS and downstream activation of KRAS. KRAS inhibitor-9 causes G2/M cell cycle arrest and induces apoptosis. KRAS inhibitor-9 selectively inhibits the proliferation of NSC-LC cells with KRAS mutation but not normal lung cells

KRAS G12C inhibitor 43 is a potent inhibitor of KRAS G12C and inhibits the migration and proliferation of H358 cells (IC50: 0.001-1 μM μM), A549 cells (IC50>1 μM) and HCC cells (IC50>1 μM).

MRTX-1257 is a selective, irreversible, and covalent inhibitor of KRAS G12C with an IC50 of 900 pM for KRAS-dependent ERK phosphorylation in H358 cells. MRTX-1257 demonstrated 31% bioavailability in the mouse, with free fraction exposures well above cellular potency, and 77% target engagement in a PK PD experiment.

K20 is a potent and selective inhibitor of KRas G12C (IC50: 1.16 nM). In H358 cells, K20 demonstrates an anticancer effect with an IC50 value of 0.78 μM and inhibits the growth of NCI-H358 tumor cells (TGI: 41%) without significant toxicity. K20 reduces the phosphorylation level of Erk, leading to apoptosis.

SHR902275 is a selective, potent, orally active RAF inhibitor targeting RAS mutant cancers, acting on cRAF (IC50: 1.6 nM), bRAFwt (IC50: 10 nM), and bRAFV600E (IC50: 5.7 nM). SHR902275 exhibits cell growth inhibitory effects in H358 cells (GI50: 1.5 nM), A375 cells (GI50: 0.17 nM), Calu6 cells (GI50: 0.4 nM), and SK-MEL2 cells (GI50: 0.32 nM).

RAS RAS-RAF-IN-1 is a potent inhibitor of RAS and RAS-RAF, exhibiting a KD of 5.0 μμ-15 μμ for cyclophilin A (CYPA) binding affinity and demonstrating antitumor activity[1].

HP661, a selective inhibitor of mitochondrial complex I (NADH dehydrogenase), impedes complex I activity by 77.6% at 1 µM, demonstrating lesser inhibition towards complex III (28.1%) and no inhibitory effects on complexes II and IV. It notably decreases the viability of human lung cancer cells—H460, NCI H441, and trametinib-resistant A549 cells (IC50s = 10.6, 29.7, and 15.1 nM, respectively)—which exhibit high levels of oxidative phosphorylation. In contrast, it shows minimal activity against NCI H358 lung cancer cells and non-cancerous HPNE and MRC-5 cells (IC50s = >10,000 nM for both), which have lower oxidative phosphorylation levels. Furthermore, in an H460 mouse xenograft model, HP661 at a dose of 30 mg/kg twice daily significantly reduces tumor volume and enhances the tumor-growth inhibitory effects of trametinib.

BI-0474 is a potent KRASG12C inhibitor that inhibits GDP-KRAS::SOS1 protein-protein interactions with an IC50 value of 7.0 nM.BI-0474 exhibits significant antiproliferative activity against NCI-H358 cells harboring the G12C mutation, and shows significant anti-tumor activity in a non-small cell lung cancer xenograft model. activity.BI-0474 can be used for cancer research.

KRAS G12C inhibitor 44 is a potent, orally active KRAS G12C inhibitor. KRAS G12C inhibitor 44 exhibits anti-proliferative effects in MIA PaCA-2 (IC50: 0.016 μM), H358 cells (IC50: 0.028 μM). inhibitor 44 has anti-tumour activity in vivo.
