Seclidemstat (SP-2577) is a potent and orally bioavailable inhibitor of lysine-specific demethylase 1 (LSD1/KDM1A) with IC50 of 13 nM. Seclidemstat (SP-2577) has potential antineoplastic activity.
The combination therapy of Seclidemstat (SP-2577) with checkpoint inhibitors may induce or augment immunogenic responses of SWI/SNF-mutated ovarian cancers. Seclidemstat promotes endogenous retroviruses (ERVs) expression and activation of IFNβ pathway in small cell carcinoma of the ovary hypercalcemic type (SCCOHT) cell lines. Seclidemstat (3 μM) promotes PD-L1 expression in SCCOHT COV 434 pIND 20 BRG1-2.7 cell line.[1]
