JAKs, a key family of cytoplasmic tyrosine kinases acting as a requisite part in the signaling process of growth factors and cytokines, important for immunity responses and hematopoiesis have become attractive targets for a considerable number of immune, inflammatory and hematopoietic diseases. Moreover, the JAK signal system has drawn significant attention(More)
Nitric oxide (NO) plays important roles in cardiovascular regulation, nerve transmission delivery and immune responses. In the last semicenturry, it has been proved that though low concentration of NO is tumor-promoting, high concentration of NO could exhibit multiple antitumor effects, which led to the research and development of kinds of NO donors and NO(More)
Abnormalities in the JAK/STAT signaling pathway lead to many diseases such as immunodeficiency, inflammation, and cancer. Herein, we designed and synthesized a series of 4-amino-(1H)-pyrazole derivatives as potent JAKs inhibitors for cancer treatment. Results from in vitro protein kinase inhibition experiments indicated that compounds 3a-f and 11b are(More)
Histone deacetylase inhibitors (HDACIs) are promising in the treatment of various diseases, among which cancer treatment has achieved the most success. We have previously developed series of HDACIs combining N-hydroxycinnamamide bioactive fragment and indole bioactive fragment, which showed moderate to potent antitumor activities. Herein, further structural(More)
JAKs inhibitors were widely applied in the treatment of immunodeficiency diseases, inflammation and cancers. We designed and synthesized a novel series of 4-aminopyrazole derivatives, which showed inhibitory potency against various JAKs. The in vitro protein kinase inhibition experiment indicated that compounds 17k, 17l, 17m and 17n could inhibit JAKs(More)
As a hot topic of epigenetic studies, histone deacetylases (HDACs) are related to lots of diseases, especially cancer. Further researches indicated that different HDAC isoforms played various roles in a wide range of tumor types. Herein a novel series of HDAC inhibitors with isatin-based caps and o-phenylenediamine-based zinc binding groups have been(More)
