R-XASYS-00128 Procyanidin B2,cas:29106-49-8 Procyanidin B2(C30H26O12,578.52) is a natural flavonoid, with anti-cancer, antioxidant activities.Procyanidin B2 shows antiproliferative activity to MCF-7 cells, with an IC50 of 19.21 μM. price>
R-XASYS-00129 Propiconazole-d7,cas:1246818-14-3 Propiconazole-d7(C15H10Cl2D7N3O2,349.3) is intended for use as an internal standard for the quantification of propiconazole by GC- or LC-MS. Propiconazole is a broad-spectrum triazole fungicide that inhibits the conversion of lanosterol to ergosterol, leading to fungal cell membrane disruption.It inhibits S. cerevisiae, but not rat liver, microsomal cytochrome P450 (IC50s = 0.04 and >200 µM, respectively). price>
R-XASYS-00130 Propionyl-L-carnitine-d3 (chloride),cas:1334532-19-2 Propionyl-L-carnitine-d3(C10H17D3NO4.Cl,256.7) is intended for use as an internal standard for the quantification of propionyl-L-carnitine by GC- or LC-MS. Propionyl-L-carnitine is a naturally occurring carnitine derivative formed by carnitine acetyltransferase during β-oxidation of uneven chain fatty acids. price>
R-XASYS-00131 Psoralidin,cas:18642-23-4 Psoralidin(C20H16O5,336.3) is a dual inhibitor of COX-2 and 5-LOX. Psoralidin, a coumestan derivative isolated from seed of Psoralea corylifolia, has been widely used in traditional medicine for bleeding, pollakiuria, enuresis, vitiligo, and psoriasis. Psoralidin shows a variety of biological activities such as anti-cancer, anti-bacterial, anti-oxidant, anti-depressant activities and regulation of insulin signaling. price>
