Biological Activity

Setidegrasib (ASP3082) is a proteolysis-targeting chimera (PROTAC) degrader targeting mutant KRAS(G12D). By selectively inducing proteasomal degradation of the KRAS(G12D) protein, it effectively suppresses downstream MAPK and PI3K/AKT signaling cascades. This targeted depletion leads to potent inhibition of cell proliferation and selective growth suppression in KRAS(G12D)-mutated tumor cell lines, including pancreatic and colorectal cancers.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
