Janus激酶(JAK)属于非受体酪氨酸激酶,其与信号转导及转录激活因子(STAT)组成的JAK-STAT信号通路可影响细胞的增殖、分化、凋亡和免疫调节。自首个JAK抑制剂获批上市以来,小分子JAK抑制剂成为全球药物研发的热点。第1代JAK抑制剂为非选择性抑制剂,尽管取得了较好的疗效,但普遍因选择性不高在临床上表现出严重毒副作用。第2代JAK抑制剂为选择性抑制剂,能更加精准地调控细胞因子在JAK-STAT通路的信号转导,有效解决了第1代JAK抑制剂存在的安全性问题。对JAK结构、JAK-STAT通路作用机制及已上市和处于Ⅲ期临床试验阶段的JAK抑制剂研究进展进行综述,旨在为该类抑制剂的研发提供参考。  相似文献

In this study, 3D‐pharmacophore models of Aurora B kinase inhibitors have been developed by using HipHop and HypoGen modules in Catalyst software package. The best pharmacophore model, Hypo1, which has the highest correlation coefficient (0.9911), consists of one hydrogen‐bond acceptor, one hydrogen‐bond donor, one hydrophobic aliphatic moiety and one ring aromatic feature. Hypo1 was validated by test set and cross‐validation methods. And the specificity of Hypo1 to Aurora B inhibitors was examined with the use of selective inhibitors against Aurora B and its paralogue Aurora A. The results clearly indicate that Hypo1 can differentiate selective inhibitors of Aurora B from those of Aurora A, and the ring aromatic feature likely plays some important roles for the specificity of Hypo1. Then Hypo1 was used as a 3D query to screen several databases including Specs, NCI, Maybridge and Chinese Nature Product Database (CNPD) for identifying new inhibitors of Aurora B. The hit compounds were subsequently subjected to filtering by Lipinski’s rule of five and docking studies to refine the retrieved hits, and some compounds selected from the top ranked hits have been suggested for further experimental assay studies.  相似文献

Preclinical Research
The Aurora family of serine/threonine kinases plays important roles in process of cell division or mitosis. Overexpression of Aurora A, B, and C has been identified in many human cancers including colon carcinoma cells. To date, a number of small molecular inhibitors have been developed for reducing Aurora kinases activities of tumor cells in preclinical and clinical trials. In this study, we describe the properties of AM‐005, a novel and orally active Aurora A/B kinase inhibitor. AM‐005 irreversibly inhibited the proliferation and levels of phospho‐Histone H3 in human colon carcinoma cell lines. Defective mitosis was also visualized in AM‐005‐treated HT29 cells by microscopy. Flow cytometric analysis showed that AM‐005 induced the accumulation of HT29 cells with >4N DNA content in a time or concentration‐dependent manner, and HT29 cells underwent severe apoptosis at 72 h. Moreover, AM‐005 given intragastrically led to suppression of the proliferative response in the xenograft model of colon carcinoma. These results indicate the utility of AM‐005 as a promising noncytotoxic agent for treating human colon carcinoma.  相似文献
