RP03707
Based on 1 Customer Validation
RP03707 is a PROTAC degrader of KRASG12D. RP03707 forms a ternary complex with KRASG12D and the CRBN E3 ligase, promoting the ubiquitination and proteasomal degradation of KRASG12D. RP03707 inhibits the growth of KRASG12D-positive tumor cells.

Biological Activity
RP03707 (0.0025-50 nM; 0-72 h) potently and rapidly degrades KRASG12D protein in AsPC-1 cells, with a DC50 of 0.6 nM and sustained degradation for up to 36 h at 1 and 10 nM[1].
RP03707 (increasing concentrations; 24 h) potently degrades KRASG12D protein in GP2D, PK-59, and AGS cells, with DC50 values ranging from 0.7 to 1.3 nM and high maximal degradation (82.0-96.0%)[1].
RP03707 (increasing concentrations; 24 h) potently inhibits ERK phosphorylation in AsPC-1, AGS, GP2D, and PK-59 cells, with IC50 values ranging from 0.35 to 10.6 nM[1].
RP03707 (increasing concentrations; 72 h) potently inhibits proliferation of AsPC-1, AGS, GP2D, and PK-59 cells, with IC50 values ranging from 0.19 to 4.19 nM[1].
RP03707 (1 μM; 0-120 min) exhibits favorable metabolic stability across multiple species, with exceptionally long human plasma stability and moderate human liver clearance[1].
