Giredestrant (GDC-9545) is a selective estrogen receptor degrader and full estrogen receptor antagonist with an IC50 of 0.05 nM in T-47D wild-type cells. By binding to estrogen receptor alpha, it induces receptor degradation and inhibits estrogen-driven transcriptional signaling. This targeted blockade disrupts cell cycle progression and exerts robust anti-proliferative activity in estrogen receptor-positive breast cancer cell lines. [1]

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).
