Biological Activity

Seclidemstat (SP-2577) is a potent, orally bioavailable inhibitor of lysine-specific demethylase 1 (LSD1/KDM1A) with an IC50 of. By reversibly inhibiting LSD1 enzymatic activity, it modulates chromatin structure and histone methylation levels, leading to the regulation of gene expression pathways. Consequently, Seclidemstat suppresses oncogenic transcriptional programs, blocks cell proliferation, and promotes differentiation and apoptosis in various cancer cell lines. [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).
