产品介绍
S2157 是 N-烷基化的反式环丙胺 (TCP) 衍生物,是一种有效的赖氨酸特异性脱甲基酶 1 (LSD1) 抑制剂。S2157 在超级增强子区域增加 H3K9 甲基化和相应的 H3K27 脱乙酰化。S2157 抑制 NOTCH3 和 TAL1 基因的转录,从而诱导 TCP 抵抗性急性淋巴细胞白血病 T-ALL 细胞凋亡 (apoptosis)。S2157 有效地透过血脑屏障,几乎可以完全根除 T-ALL 细胞移植小鼠的中枢神经系统白血病。

产品描述

S2157, a N-alkylated tranylcypromine (TCP) derivative, is a potent lysine-specific demethylase 1 (LSD1) inhibitor. S2157 increases H3K9 methylation and reciprocal H3K27 deacetylation at super-enhancer regions. S2157 induces apoptosis in TCP-resistant T-cell acute lymphoblastic leukemia (T-ALL) cells by repressing transcription of the NOTCH3 and TAL1 genes. S2157 efficiently pass through the blood-brain barrier and can almost completely eradicate CNS leukemia in mice transplanted with T-ALL cells[1].

S2157 is particularly effective for T-ALL cell lines with the IC50 values between 1.1 µM for human T-ALL cell lines CEM and 6.8 µM for MOLT4[1]. S2157 (4-20 µM; 72 hours) modestly inhibits mitogen-activated normal T-lymphocytes[1]. S2157 (4-8 µM; 24 hours) induces apoptosis and down-regulates the expression of NOTCH3 and TAL1 proteins in T-cell acute lymphoblastic leukemia (T-ALL) cells[1].

S2157 (50 mg/kg; IP; 3 times a week; for 28 days) causes the size of subcutaneous tumors reduced to less than 20% of that in the untreated control[1]. S2157 (50 mg/kg; IP) has a T1/2 of 0.88 hours, a Cmax of 4.33 μM and an AUC of 5.75 μM•h[1]. S2157 (30 mg/kg or 50 mg/kg; twice a week for 3 weeks) almost completely suppressed the growth of MOLT4 cells in most but not all NOD/SCID mice with MOLT4 cells. S2157 eradicates CNS leukemia in murine xenotransplanted models[1].
