SOS1-IN-26
SOS1-IN-26 is a potent, orally active selective allosteric SOS1 inhibitor with a KD of 33 nM and SOS1-KRAS binding IC50 of 4.0 nM. SOS1-IN-26 disrupts SOS1-KRAS interaction, inhibits MAPK/PI3K signaling, induces G1 phase arrest and tumor cell apoptosis. SOS1-IN-26 serves as a balanced lead therapeutic candidate for pan-KRAS-driven colorectal cancer studies.

SOS1-IN-26 (78b) potently blocks SOScat-catalyzed nucleotide exchange of G12V and G12D mutant KRAS with IC50 values of 24 nM (G12V) and 20 nM (G12D), while barely suppressing EGFR activity at 1 μM and thus displaying favorable EGFR kinase selectivity[1].
SOS1-IN-26 (10 μM; 40 min) markedly elevates the thermal stability of SOScat[1].
SOS1-IN-26 binds SOS1 to break SOS1-KRAS interaction, showing reduced fluorescence polarization (FP=84 mP) and robust SOS1-KRASG12C binding inhibition (IC50=4.0 nM)[1].
SOS1-IN-26 (120 h) exerts strong inhibitory activity across all tested CRC cell lines (IC50 of 93-321 nM) in 3D cell culture, with stronger potency than that observed in 2D cell culture[1].
SOS1-IN-26 (1 μM; 0-60 min) exhibits moderate intrinsic clearance (CLint=19.06 mL/min/kg) and a T1/2 of 91.18 min in human liver microsomes[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
SOS1-IN-26 (500 mg/kg; p.o.; single dose) possesses high tolerable doses and favorable safety profiles in Balb/c mice[1].
SOS1-IN-26 (30-60 mg/kg; p.o.; once daily; for 18 days) inhibits tumor growth and demonstrates a good safety profile in HCT116 xenograft models[1].
