BTX-6654 is a SOS1 PROTAC degrader. BTX-6654 induces ubiquitination and degradation of SOS1 via the proteasomal pathway by bridging SOS1 with the E3 ligase CRBN to form a ternary complex, thereby blocking KRAS activation and downregulating the MAPK signaling pathway (pERK/pS6), and ultimately inhibiting tumor growth. BTX-6654 can be used in research on various cancers driven by KRAS mutations.

In Vitro

BTX-6654 potently and specifically degrades SOS1 in KRAS-mutant cancer cells, with a DC₅₀ value of < 11 nM; it also inhibits the downstream pERK and pS6 signaling pathways, with corresponding IC₅₀ values of 1-32 nM and 4-22 nM, respectively^[1].
BTX-6654 potently inhibits the viability of specific human cancer cell lines (including MIA PaCa-2, A549, NCI-H1975 and SNU-175), with IC₅₀ values as low as 1.2 nM, but shows no significant activity against many other cancer cell lines with specific KRAS, NRAS, BRAF, NF1 mutations or KRAS deletion status (IC₅₀ >2500 nM)^[1].

Western Blot Analysis^[1]

Cell Line:

MIA PaCa-2 (3D)
Concentration:

0.8, 4, 20, 100, 500 nM
Incubation Time:

24 h
Result:

In Vivo

BTX-6654 (25-40 days) dose-dependently degrades SOS1 protein and inhibits tumor growth in two KRAS G12C xenograft mouse models, and exerts a synergistic tumor growth inhibitory effect when combined with the KRAS inhibitor (Sotorasib) (HY-114277) or the MEK inhibitor (Trametinib) (HY-10999)^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

BALB/c nude mice (6-8 weeks old, female) were subcutaneously inoculated with NCI-H358 cells in the right flank^[1]
Dosage:

10, 50 mg/kg
Administration:

i.p.; single dose; 2, 8, 24 h
Result:

Downregulated SOS1 and pERK proteins in histology.

Animal Model:

BALB/c nude mice (6-8 weeks old, female) were subcutaneously inoculated with NCI-H358 cells or MIA PaCa-2 cells in the right flank^[1]
Dosage:

2, 10 mg/kg
Administration:

i.p.; twice daily; 28 days
Result:

Inhibited tumor growth in a dose-dependent manner.
No significant effect on animal body weight.

Animal Model:

BALB/c nude mice (6-8 weeks old, female) were subcutaneously inoculated with xMIA PaCa-2 cells in the right flank^[1]
Dosage:

10 mg/kg (+ 10 mg/kg Sotorasib or 0.125 mg/kg Trametinib)
Administration:

i.p.; twice daily; 30 days

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
