Seclidemstat mesylate

Seclidemstat (SP-2577) mesylate is a potent noncompetitive and reversible KDM1A (LSD1) inhibitor (Ki=31 nM, IC50=13 nM). Seclidemstat mesylate promotes antitumor immunity in switch/sucrose nonfermentable (SWI/SNF) complex mutated ovarian cancer, as well as inhibit virus production, viral DNA replication, and late gene expression. Seclidemstat mesylate can be used for the research of Ewing Sarcoma.

How to use

In Vitro:

Seclidemstat (72 hours) mesylate inhibits SWI/SNF-mutation-dependent tumor cell proliferation with IC50 ranging from 0.013 to 2.819 μM (COV434, BIN67, SCCOHT-1, TOV21G, SKOV3, A427, H522, A549, H1299, G401, G402, HCC15 cells). Seclidemstat (72 hours) mesylate promotes endogenous retroviruses (ERVs) expression and activation of IFNβ pathway in SCCOHT cell lines (SCCOHT-1, BIN67, and COV434 cells). Seclidemstat (3 μM) mesylate promotes PD-L1 expression in SCCOHT COV 434 pIND 20 BRG1-2.7 cell line.
