| Description | DJ001 is a highly specific, selective and non-competitive protein tyrosine phosphatase σ (PTPσ) inhibitor with IC50 of 1.43 μM. DJ001 promotes the regeneration of hematopoietic stem cells. |
| In vitro | 与对照培养相比，DJ001（5-1000 ng/mL；3-7天；BM KSL细胞）处理可提升培养中BM KSL细胞的百分比和数量。此外，DJ001处理显著增加了培养3天的BM KSL细胞中集落形成细胞（CFC）的数量。BM KSL细胞经300 cGy辐照后，在含有1 μg/mL DJ001及不含1 μg/mL DJ001但包含20 μng/mL巨大血小板生成素、100 μg/mL干细胞因子（SCF）、50 μg/mL Flt3配体、TSF的培养基中培养了3天。与对照培养相比，DJ001处理能提高BM CFC的恢复率以及多潜能集落形成单位-类粒细胞红细胞单核细胞巨核细胞（CFU-GEMM）集落的数量[1]。 |
| In vivo | DJ001通过激活RhoGTPase、RAC1和诱导BCL-XL抑制受辐射诱发的HSC凋亡。在雌性C57BL/6小鼠中，DJ001（5μg/kg；皮下注射；持续时间24小时）显著降低了500°cGy全身辐射（TBI）24小时后BM KSL细胞的凋亡百分比[1]。 |
