CSN13680ABT-1991257044-40-8ABT-199 is a highly potent inhibitor of Bcl-2, re-engineered from ABT-263. It has subnanomolar affinity (Ki<0.010 nM, analysis by TR–FRET assay), which is over three orders of magnitude to Bcl-XL (Ki=48nM) and Bcl-W (Ki=245 nM).
CSN16807Imatinib Mesylate220127-57-1Imatinib Mesylate is the mesylate form of Imatinib. Imatinib is a multiple target inhibitor with IC50 values of 100nM, 100nM, 38nM, 25nM and 25nM for PDGFR, c-kit, v-Abl, c-abl and bcr-abl, respectively, usually used for treatment of chronic myelogenous leukemia.
CSN13702Salicin138-52-3Salicin is a non-selective COX-1 and COX-2 inhibitor, it is a phenol β-glycosid isolated and purified from the peel of Salix alba L.and shows anti-inflammatory effects.
CSN11280Lenalidomide191732-72-6Lenalidomide, a thalidomide analog, is a TNF-α secretion inhibitor with IC50 of 13 nM.
CSN12073Thalidomide50-35-1Thalidomide interacts directly with the protein cereblon (CRBN; IC50 = 8.5 nM), a ubiquitously-expressed E3 ligase. And binding of thalidomide analogs to CRBN-DNA damage binding protein-1 complexes (CRBN-DDB1-Cul4A complex) account for the immunomodulatory and antiproliferative effects of these compounds.
CSN13185Pomalidomide19171-19-8Pomalidomide inhibits lipopolysaccharide (LPS) stimulated TNF-alpha release in human PBMC and in human whole blood with IC50 values of 13 nM and 25 nM, respectively. Pomalidomide inhibits the growth of T regulatory cells which is stimulated by IL-2 with an IC50 of ~1 μM. Treatment with Pomalidomide (6.4 nM-10 μM) increases the production of IL-2 in human peripheral blood T cells, and is slightly more potent in the CD4+ subset than in the CD8+ subset. Pomalidomide is significantly more potent than CC-5013 at elevating IL-2, IL-5, and IL-10 levels, but only slightly more potent than CC-5013 at elevating IFN-γ levels. Pomalidomide enhances SEE and Raji cells induced AP-1 transcriptional activity in Jurkat cells in a dose-dependent manner, with a maximal enhancement of 4-fold at 1 μM. Exposure of Raji cells to various concentrations of Pomalidomide (2.5-40 μg/mL) for 48 hours leads to a significant decrease in cell proliferation and DNA synthesis. There is a reduction of ~40% compared to vehicle-treated controls.
CSN16132Mycophenolate mofetil128794-94-5Mycophenolate mofetil is a non-competitive, selective and reversible inhibitor of inosine monophosphate dehydrogenase I/II with IC50 of 39 nM and 27 nM, respectively.
