| 体外研究 | Hydroxyurea is a DNA synthesis inhibitor, and can inhibit HIV-1 replication. In vitro experiments have shown that the 90% inhibitory concentration (IC90) of hydroxyurea for laboratory strains of HIV-1 in activated PBMC is 0.4mM. Hydroxyurea was also found to be synergistic with the nucleoside reverse transcriptase inhibitor didanosine and to inhibit HIV-1 replication in activated PBMC; this inhibition may be due to a reduction in deoxynucleoside triphosphate pool sizes. Hydroxyurea has been shown to sensitize didanosine-resistant mutants. Hydroxyurea has demonstrated activity in the treatment of sickle cell anemia by increasing the production of fetal hemoglobin, which reduces hemolysis in patients with this disease. Hydroxyurea exerts its cytostatic effect through inhibition of ribonucleotide reductase—the rate-limiting enzyme responsible for the conversion of ribonucleotides to deoxyribonucleotides, which are essential for DNA synthesis. As a result, cellular division is arrested in the S phase. |

| 方法 | Erythroid cells obtained from peripheral blood of the same patients(Thirteen β-Thal/HbE patients are treated with hydroxyurea orally for 2 years at a starting dose of 5mg/kg/day for 5 days/week with escalation to a maximum of 10mg/kg/day) 1 year after they had stopped hydroxyurea treatment are treated with hydroxyurea in vitro. Treatment of cells performs in primary culture with 30μM hydroxyurea for 96 hours. |

fanjingol 请教一下各位前辈:关于JNK的抑制剂,我查阅了相关文献,只看到了SP600125(Calbiochem, San Diego, CA USA)这一种。请问有做过相关实验的前辈们,能否告知我JNK的抑制剂到底有几种?因为JNK蛋白激酶由3个基因编码,那么此抑制剂是否均抑制jnk 1和jnk 2以及JNK3,还是只针对某一个JNK基因编码的JNK蛋白激酶?换而言之,就是此种JNK抑制剂的特异性如何?请前辈们解答!谢谢了
