一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
Flavopiridol hydrochloride是一种选择性的CDK1、CDK2、CDK4和CDK6抑制剂,IC50值均为约41 nM,对CDK7的IC50值为300nM[1][2][3]。据报道,flavopiridol hydrochloride也抑制表皮生长因子受体和蛋白激酶A,IC50值分别为21和122 μM[3]。
CDKs蛋白激酶家族参与调节转录、mRNA加工、细胞分化和细胞周期过程。据报道,CDKs在多种细胞中异常表达[3]。
Flavopiridol hydrochloride是一种有效的CDK抑制剂,不同于UCN-01。在乳腺癌细胞系MCF-7中,flavopiridol hydrochloride具有高抑制能力,通过抑制CDK2和CDK4,诱导G1期细胞周期阻滞[1]。在7个淋巴瘤细胞系中,flavopiridol hydrochloride以400 nM的浓度处理后通过抑制CDK4、CDK6、CDK7或CDK9,从而抑制Rb的磷酸化和抗凋亡蛋白(Mcl-1和XIAP),进而诱导细胞凋亡[4]。
在HL-60皮下异种移植小鼠模型中,flavopiridol hydrochloride(7.5 mg/kg)静脉给药后诱导91.67%的晚期动物肿瘤完全消退,并在flavopiridol治疗一个疗程后,保持几个月的无病状态[5]。
