产品描述	SPHINX31 is a potent inhibitor of serine/arginine-rich protein kinase 1 (SRPK1; IC50: 5.9 nM).
靶点活性	SRPK1:5.9 nM (cell free)
体外活性	SPHINX31 inhibits phosphorylation of serine/arginine-rich splicing factor 1 (SRSF1), an SRPK1 substrate, in PC3 cells (EC50: 360 nM) and increases expression of the anti-angiogenic VEGF-A165b splice variant in retinal pigment epithelial (RPE) cells [1]. SPHINX31 inhibited the growth of MLL-mutant AML cell lines with an IC50? >1 order of magnitude lower than for other AML lines. There was no impact of SPHINX31 on the clonogenic potential of normal mouse hematopoietic stem-progenitor cells (HSPCs). 1.5, 3, and 6?μM SPHINX31 did not affect the colony-forming ability of normal human cord blood CD34+ cells [2].
体内活性	In vivo, SPHINX31 (2 μg per eye) inhibits blood vessel growth and macrophage infiltration in the eyes of a mouse model of choroidal neovascularization [1]. Injection of 0.8?mg/kg SPHINX31 (i.p.) into DBA2J mice resulted in a concentration of 0.225?±?0.036?μM in plasma after 24?h. In xenotransplanted RAIL mice with MOLM-13, THP-1 cells or first passage patient-derived AMLs, SPHINX31 (0.8 or 2.0 mg/kg) led to a significant reduction in leukemic cell growth and a dose-dependent prolongation of survival of mice given MOLM-13, THP-1, and patient-derived MLL-X AMLs [2].
细胞实验	Cells were transduced with gRNA vectors or treated with SPHINX31 and stained at the indicated time points with anti-mouse CD11b PE/Cy5 and anti-human CD11b PE or anti-human CD13 FITC. Data were analyzed by using LSRFortessa and FlowJo. Apoptosis levels were measured in human and/or mouse AML cells transduced with dual gRNA vectors (against SRPK1 and 3' BCL2 enhancer) and/or treated with 1 or 3?μM SPHINX31 at indicated time points, by using Annexin V. Data were analyzed by using LSRFortessa instruments. Cell cycle stages were measured in human and/or mouse AML cells transduced with dual gRNA vectors against SRPK1 and/or treated with 1 or 3?μM SPHINX31 at indicated time points, using Propidium Iodide. Data were analyzed using LSRFortessa instruments [2].
动物实验	For in vivo experiments, 6–10-week-old female Rosa26Cas9/+ mice were treated triweekly for two weeks with either vehicle or 2?mg/kg SPHINX31. Four weeks post-treatment, bone marrow cells from these mice were freshly extracted (as mentioned above) and blocked with anti-mouse CD16/32 and 10% mouse serum. For the identification of LK/LSK, LT-HSC, myeloid and B-cell subpopulations, staining was performed using CD4 PE/Cy5, CD5 PE/Cy5, CD8a PE/Cy5, CD11b PE/Cy5, B220 PE/Cy5, TER-119 PE/Cy5, GR-1 PE/Cy5, SCA-1 Pacific Blue, CD150 PE/Cy7, CD34 FITC and CD117 APC-eFluor780. In each of the multi-colour flow cytometry experiments, we included the fluorescence minus one (FMO) controls. FMO controls provide a measure of spillover in a given channel. This allows for correct gating and selects only the stained cells in the experimental sample. Flow cytometry analysis was performed using a LSRFortessa instrument and resulting data were subsequently analyzed using FlowJo [2].

体内实验配液计算器

请在以下方框中输入您的动物实验信息后点击计算，可以得到母液配置方法和体内配方的制备方法：比如您的给药剂量是10 mg/kg，每只动物体重20 g，给药体积100 μL，一共给药动物10 只，您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。

母液配置方法：2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL)，如您需要配置的浓度超过该产品的溶解度，请先与我们联系。

体内配方的制备方法：取 50 μL DMSO 主液，加入 300 μL PEG300，混匀澄清，再加 50 μL Tween 80，混匀澄清，再加 600 μL ddH2O, 混匀澄清。
