Biological Activity
DTHIB is a direct and selective heat shock factor 1 (HSF1) inhibitor that binds to the HSF1 DNA-binding domain with a Kd of 160 nM. By blocking HSF1 transcriptional activity, DTHIB attenuates heat shock response signaling, suppresses androgen receptor gene expression, and inhibits cancer cell proliferation and tumor growth in prostate cancer models.

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).
Pre-aliquoted for Longevity: Solid-state aliquots offer longer shelf life compared to stock solutions.
