This invention relates to antibodies capable of binding to the FK778 substance, to a highly-sensitive immunoassay method, which utilizes an antibody for the FK778 substance, and to a test kit for measuring the concentration of the FK778 substance.
Exploration of Janus Kinase (JAK) and Histone Deacetylase (HDAC) Bispecific Inhibitors Based on the Moiety of Fedratinib for Treatment of Both Hematologic Malignancies and Solid Cancers
pathway leads to the fact that solid cancers are not sensitive to histone deacetylase (HDAC) inhibitors. Herein, a series of novel 2-amino-4-phenylaminopyrimidine JAK/HDAC dual-target inhibitors based on the moiety of fedratinib were designed and synthesized. Among them, 21 and 30 potently inhibited HDAC3/6 and JAK1/2 at nanomolar levels and exhibited splendid selectivity for the JAK2 against a panel

A series of hybrids containing the pharmacophores of the histone deacetylase (HDAC) inhibitor, SAHA, and the antioxidant ebselen were designed and synthesized as multi-target-directed ligands against Alzheimer's disease. An in vitro assay indicated that some of these molecules exhibit potent HDAC inhibitory activity and ebselen-related pharmacological effects. Specifically, the optimal compound 7f was found to be a potent HDAC inhibitor (IC50 = 0.037 mu M), possessing rapid hydrogen peroxide scavenging activity and glutathione peroxidase-like activity (nu(0) = 150.0 mu M min(-1)) and good free oxygen radical absorbance capacity (value of ORAC: 2.2). Furthermore, compound 7f showed significant protective effects against damage induced by H2O2 and the ability to prevent ROS accumulation in PC12 cells.
