Ordering Information

Biological Activity

YF-2 is a blood-brain barrier permeable activator of histone acetyltransferases, demonstrating selectivity for CBP alongside activation of PCAF, GCN5, and p300. By enhancing histone acetyltransferase enzymatic activity, YF-2 promotes histone hyperacetylation and downstream transcription, facilitating chromatin remodeling associated with synaptic plasticity and neuroprotective signaling pathways. These molecular effects enhance central nervous system function and cognitive performance in preclinical studies. [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).
