Triciribine是DNA合成的抑制剂,对Akt和HIV-1的IC50值分别为130 nM和20 nM[1,2]。
蛋白激酶B(PKB),亦称Akt,是一种丝氨酸/苏氨酸特异性蛋白激酶,在多种细胞进程中发挥重要作用,如葡萄糖代谢、细胞凋亡、细胞增殖、转录和细胞迁移。一旦Akt的PH域结合磷酸酯,活化的Akt可以通过其激酶活性继续激活或者去活化其多种底物,如核因子-κB、Bcl-2家族蛋白和鼠双微粒体2(MDM2)[3]。研究表明,具有持续活化Akt的肿瘤细胞依赖Akt而存活[4]。所以Akt抑制剂可能用于治疗肿瘤。
Triciribine也称为API-2,抑制Akt的磷酸化水平和激酶活性,诱导癌细胞凋亡,抑制细胞生长。Triciribine能特异性抑制大部分常见星形细胞瘤细胞,抑制效率非常低(GI50值为13.6 mM [5])。Triciribine能抑制HIV-1,IC50值为20 nM。0.1 M的抑制率超过90%,5 M则会完全抑制多核细胞。HIV-1感染的CEM-SS、H9及p24核心抗原B和U1持续感染的H9III细胞中的毒性试验表明Triciribine浓度的选择范围为46 M至2250,Triciribine能以剂量依赖的方式显著抑制HIV-1诱导产生、逆转录酶以及感染病毒的产生[6]。Triciribine抑制人前列腺癌细胞系PC-3 Akt 308位酸和473位丝氨酸磷酸化和Akt活性。Triciribine能使PC-3细胞对TRAIL和anti-CD95诱导的凋亡更加敏感,但仍然耐受化疗引起的DNA损伤[7]。Triciribine也能选择性抑制Akt1、Akt2和Akt3,而不抑制已知的Akt上游激活剂PDK1和PI3K。此外,低微摩尔和亚微摩尔浓度的Triciribine具有抗肿瘤和抗病毒活性,其也能抑制氨基酸掺入蛋白质及嘌呤核苷酸合成。
