R-XASYS-00092 L-Cysteine-15N-d3,cas:1795787-05-1 L-Cysteine-15N-d3(C3H4D3[15N]O2S,125.2) is intended for use as an internal standard for the quantification of L-cysteine by GC- or LC-MS. L-Cysteine is a conditionally essential amino acid.It is produced from L-methionine through the transsulfuration pathway.L-Cysteine can also be derived from dietary sources and protein turnover. price>
R-XASYS-00093 L6H21,cas:24533-47-9 L6H21(C18H18O4,298.3) is an inhibitor of myeloid differentiation 2 (MD-2), also known as lymphocyte antigen 96 (LY96).It binds to MD-2 (Kd = 33.3 µM in a cell-free assay) and inhibits the protein-protein interaction between MD-2 and toll-like receptor 4 (TLR4) in LPS-stimulated ECV304 cells. L6H21 (10 µM) decreases the migration of LPS-stimulated HCT116 colon cancer cells. price>
R-XASYS-00094 Lecanoric Acid,cas:480-56-8 Lecanoric acid(C16H14O7,318.3) is a naturally occurring depside polyphenol isolated from a variety of lichens. It is a potent antioxidant, surpassing ascorbic acid in a 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) free radical scavenging assay (IC50s = 424.51 and 6.42 μg/ml for lecanoric and ascorbic acid, respectively). Lecanoric acid has antibacterial and antifungal activities with minimum inhibitory concentrations ranging from 0.5 to 1 mg/ml for a panel of fifteen microorganisms. price>
R-XASYS-00095 Leucettine L41,cas:1112978-84-3 Leucettine L41 is an inhibitor of dual-specificity tyrosine phosphorylation-regulated kinase 1A (DYRK1A), DYRK2, CDC-like kinase 1 (CLK1), and CLK3 (IC50s = 0.04, 0.035, 0.015, and 4.5 μM, respectively).It also inhibits GSK3α/β and Pim1 with IC50 values of 0.41 and 4.1 μM, respectively. It inhibits phosphorylation of the serine/arginine (SR) protein 9G8 by DYRK2, DYRK3, CLK1, CLK2, and CLK4 and inhibits TNF-α-induced SRp75 and SRp55 phosphorylation in human microvascular endothelial cells when used at concentrations ranging from 0.1 to 10 μM price>
