β-Lapachone產品描述:β-Lapachone(ARQ-501; beta-lapachone) is a naturally occurring quinone obtained from the bark of the lapacho tree (Tabebuia avellanedae) with cancer chemopreventive properties; potent inhibitor of IDO1(IC50=0.44 uM).IC50 value: 0.44 uM (IDO1)Target: IDO1 inhibitor; anticancer agentin vitro: β-Lapachone markedly induced cell death without caspase activation. β-Lapachone increased PI uptake and HMGB-1 release to extracellular space, which are markers of necrotic cell death. Necrostatin-1 (a RIP1 kinase inhibitor) markedly inhibited β-lapachone-induced cell death and HMGB-1 release. In addition, β-lapachone activated poly (ADP-ribosyl) polymerase-1(PARP-1) and promoted AIF release, and DPQ (a PARP-1 specific inhibitor) or AIF siRNA blocked β-lapachone-induced cell death [1]. In H9C2 cells, β-lap-mediated elevation of AMPK activity was retarded when the level of Sirt1 was reduced by transfection of siRNA against Sirt1 [2]. β-lapachone was identified as a submicromolar inhibitor of ID 公司介紹:MedChemExpress(MCE)專注于各種抑制劑、激動劑、API及化合物庫,總部位于美國新澤西,分別在瑞典和上海設有歐洲區(qū)子公司和亞洲區(qū)總代理,營銷網點遍及全球20多個國家地區(qū)。MCE經過多年努力已成為全球生物活性小分子領域的一流供應商, 產品涵蓋癌癥、神經科學、抗感染、表觀遺傳學等20個熱門研究領域,PI3K、MAPK等近千個細分靶點,超過4000個活性小分子化合物現貨,以及GPCR、API、離子通道等超過20種不同類型的化合物庫,同時提供從毫克到千克的專業(yè)定制合成服務。 MCE 對每批產品都進行嚴格的LCMS和NMR檢驗,其產品已被全球近萬名客戶廣泛使用并發(fā)表大量文章、專利; MCE 定期增加各領域熱門抑制劑、激動劑,不斷擴增已有化合物庫,以滿足最新的科研需求; 數千種產品在上海有充足備貨,24-48小時內送達客戶; 大量產品提供免費試用裝;已為全球多個知名企業(yè)、院校構建各種定制型化合物庫。 產品鏈接:www.medchemexpress.cn/_beta_-lapachone.html |
