A-940894 is a histamine H4 receptor antagonist with anti-inflammatory properties. A-940894 potently binds to both human and rat histamine H4 receptors and exhibits considerably lower affinity for the human histamine H1, H2, or H3receptors. A-940894 has g
JNJ-10191584, a potent and selective antagonist at the histamine H4 receptor, has antiinflammatory and analgesic effects in animal studies of acute inflammation.
H3R antagonist 2 (Compound 23) is a multitarget histamine H3receptor antagonist. It exhibits inhibitory effects on acetylcholinesterase, butyrylcholinesterase, and human monoamine oxidase B (hMAO B) with IC50 values of 180 nM, 880 nM, and 775 nM, respectively. With a Ki of 170 nM for hH3R, H3R antagonist 2 demonstrates favorable anti-neuropathic pain and memory-enhancing effects. Additionally, it can cross the blood-brain barrier (BBB) [1].
MHY219 is a novel HDAC inhibitor. MHY219 induces apoptosis via up-regulation of androgen receptor expression in human prostate cancer cells. MHY219 was shown to enhance the cytotoxicity on DU145 cells (IC50, 0.36 μM) when compared with LNCaP (IC50, 0.97 μM) and PC3 cells (IC50, 5.12 μM). MHY219 showed a potent inhibition of total HDAC activity when compared with SAHA. MHY219 increased histone H3 hyperacetylation and reduced the expression of class I HDACs (1, 2 and 3) in prostate cancer cells. MHY219 effectively increased the sub-G1 fraction of cells through p21 and p27 dependent pathways in DU145 cells. MHY219 significantly induced a G2 M phase arrest in DU145 and PC3 cells and arrested the cell cycle at G0 G1 phase in LNCaP cells. Furthermore, MHY219 effectively increased apoptosis in DU145 and LNCaP cells, but not PC3 cells, according to Annexin V PI staining and Western blot analysis. These results indicate that MHY219 is a potent HDAC inhibitor that targets regulating mu......
