Biological Activity

Santacruzamate A (CAY10683) is a potent and selective histone deacetylase (HDAC) inhibitor targeting HDAC2. By blocking HDAC activity, it modulates histone acetylation status and chromatin structure, leading to alterations in gene expression pathways. This downstream epigenetic regulation promotes cell cycle arrest and induces apoptosis, resulting in the inhibition of cellular proliferation in susceptible cell populations. [1]

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).
