Background | Pracinostat is a potent histone deacetylase (HDAC) inhibitor. |
Biological Activity | Pracinostat 是一种有效的组蛋白去乙酰化酶 (HDAC) 抑制剂,对 HDACs 的 IC50 值为 40-140 nM,可用于癌症研究。[1-3] |
In Vitro | Pracinostat(SB939)是一种有效的新型异羟肟酸类HDACs I,II和IV抑制剂,抑制分离的酶,Ki为19至48 nM(I类),16至247 nM(II类),和43 nM(IV类),但对III类同工酶SIRT I没有活性.SB939对HCT-116结肠癌细胞系和HL-60急性髓细胞白血病细胞系有影响,IC50分别为0.48μM和70 nM 。 SB939在高达100μM的浓度下不抑制正常人皮肤成纤维细胞的增殖[1]。 Pracinostat(SB939,化合物3)抑制CYP2C19,IC50为5.78μM。 SB939显示针对A2780,COLO 205,HCT-116和PC-3细胞系的有效活性,IC50为0.48±0.21,0.56±0.08,0.48±0.27和0.34±0.06 [2]。 Pracinostat下调JAK2V617F和FLT-ITD细胞系中的JAK和FLT3信号传导,并显示与pacritinib组合的协同作用。 Pracinostat和pacritinib显示STAT信号传导和细胞凋亡的体外协同作用。 Pracinostat有效抑制不同AML亚型作为单一药物的增殖,并且与JAK2V617F或FLT3-ITD AML细胞系中的pacritinib具有协同作用[3]。 |
In Vivo | Pracinostat(SB939,25-100mg/kg)显示HCT-116异种移植物的显著剂量依赖性生长抑制。 SB939选择性地在肿瘤组织中累积。 SB939(50或75 mg/kg)在Apcmin基因结肠癌小鼠模型中显示出抗肿瘤活性[1]。在携带MV4-11异种移植物的小鼠中,Pracinostat(25或50mg/kg每天,持续21天)分别诱导显著抑制肿瘤生长(TGI)59和116%。 Pracinostat(75mg/kg,qod)与pacritinib组合在两种不同的人AML模型中在体内是有效的和协同的。 Pracinostat和pacritinib对AML诱导的血浆细胞因子/生长因子/趋化因子具有协同作用[3]。 |
Cell Experiment | 在对数生长期,将细胞以预定的最佳密度接种在96孔板中,并在用SB939处理之前分别静置24小时(贴壁细胞)或2小时(悬浮细胞)。 |
Animal Experiment | 在治疗期间,给小鼠腹膜内注射40mg/kg的5-FU,体积为200μL/ 20g体重,每日一次,治疗5天,然后进行9天的恢复期,再加5天。治疗。每天口服50或75mg/kg口服SB939连续给药21天。在治疗的最后一天,取出小肠,盲肠和结肠;通过多次注射4%PBS缓冲的甲醛固定到肠腔中;切成段;并平放在甲醛浴中的塑料薄膜上。在解剖显微镜中测量肿瘤负荷[1]。 |
