s 2116

S2116 is a powerful inhibitor of lysine-specific demethylase 1 (LSD1), and it is a derivative of N-alkylated tranylcypromine (TCP). S2116 exhibits its inhibitory effects by increasing H3K9 methylation and inducing reciprocal H3K27 deacetylation at super-enhancer regions. In TCP-resistant T-cell acute lymphoblastic leukemia (T-ALL) cells, S2116 triggers apoptosis by repressing the transcription of NOTCH3 and TAL1 genes. Furthermore, S2116 demonstrates significant growth retardation of T-ALL cells when xenotransplanted into mice.
