RP04340
RP04340 is an orally active, selective pan-KRAS PROTAC degrader. RP04340 hijacks the CRBN E3 ligase and the cellular proteasome system to degrade KRAS, without degrading HRAS, NRAS, or common CRBN neosubstrates. RP04340 inhibits KRAS downstream signaling pathways, including pERK and DUSP6. RP04340 exhibits anticancer activity in various KRAS-mutant cancers. RP04340 can be used to study kras-driven cancers, including pancreatic ductal adenocarcinoma, colorectal cancer, and lung adenocarcinoma.

体外実験
RP04340 (0-1000 nM; 24 h) is a potent selective KRAS degrader that achieves low nanomolar DC50 values in KRASG12D AsPC-1, KRASG12C MIA PaCa-2, and KRASG12V NCI-H727 cell lines, with no observed activity against HRAS or NRAS[1].
RP04340 (0.1-1000 nM; 72 h) demonstrates potent low nanomolar antiproliferative activity in KRASG12D AsPC-1, KRASG12C MIA PaCa-2, and KRASG12V NCI-H727 cell lines[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

-
Concentration:0, 0.1, 1, 10, 100, 1000 nM
-
Incubation Time:24 h
-
Result:Potently degrades KRAS protein across multiple KRAS mutant lines, with DC50 values of 13.5 nM (AsPC-1), 2 nM (MIA PaCa-2), 13.1 nM (NCI-H727), and achieves >80% Dmax for KRAS degradation.
Does not induce degradation of HRAS or NRAS even at 1000 nM in PK-59 cells.

体内実験
RP04340 (25-100 mg/kg; p.o.; once daily; 21 days) induces dose-dependent tumor regression in the MIA PaCa-2 KRASG12C xenograft model, with a tumor regression rate of up to 59.5% at a dose of 100 mg/kg[1].
RP04340 (25-100 mg/kg; p.o.; once daily; 28 days) administered orally once daily for 28 days in the NCI-H727 KRASG12V xenograft model achieves a tumor growth inhibition rate of 75.4% at a dose of 100 mg/kg[1].
