<a href="https://www.medchemexpress.com/Amsacrine.html">Amsacrine</a>產品描述：Amsacrine is an inhibitor of <b>topoisomerase</b>, specifically inhibiting topoisomerase II, and acts as an antineoplastic agent which can intercalates into the DNA of tumor cells.<i><b>In Vitro:</b></i> Amsacrine blocks HERG currents in HEK 293 cells and Xenopus oocytes in a concentration-dependent manner, with IC<sub>50</sub> values of 209.4 nm and 2.0 μM, respectively. Amsacrine causes a negative shift in the voltage dependence of both activation (−7.6 mV) and inactivation (−7.6 mV). HERG current block by amsacrine is not frequency dependent<sup>[1]</sup>. In vitro studies of normal human lymphocytes with various concentrations of m-AMSA, show both increased levels of chromosomal aberrations, ranging from 8% to 100%, and increase SCEs, ranging from 1.5 times the normal at the lowest concentration studied (0.005 μg/mL) to 12 times the normal (0.25 μg/mL)<sup>[3]</sup>. Amsacrine-induced apoptosis of U937 cells is characterized by caspase-9 and caspase-3 activation, increased intra<br><br><br><span style="outline: 0.0px;line-height: 22.0px;color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;background-color: rgb(251,251,251);">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。</span><br style="color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;line-height: 22.0px;background-color: rgb(251,251,251);"><span style="outline: 0.0px;line-height: 22.0px;color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;background-color: rgb(251,251,251);">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；</span><br style="color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;line-height: 22.0px;background-color: rgb(251,251,251);"><span style="outline: 0.0px;line-height: 22.0px;color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;background-color: rgb(251,251,251);">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；</span><br style="color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;line-height: 22.0px;background-color: rgb(251,251,251);"><span style="outline: 0.0px;line-height: 22.0px;color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;background-color: rgb(251,251,251);">數千種產品在上海有充足備貨，24-48小時內送達客戶；</span><br style="color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;line-height: 22.0px;background-color: rgb(251,251,251);"><span style="outline: 0.0px;line-height: 22.0px;color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;background-color: rgb(251,251,251);">大量產品提供免費試用裝；</span><span style="outline: 0.0px;line-height: 22.0px;color: rgb(62,62,62);font-family: "Helvetica Neue" , Helvetica , Arial , sans-serif;font-size: 11.818182px;background-color: rgb(251,251,251);">已為全球多個知名企業(yè)、院校構建各種定制型化合物庫。</span><br><br>產品鏈接：<a href="http://www.medchemexpress.cn/amsacrine.html">www.medchemexpress.cn/amsacrine.html</a><br><br></span><img style="width: 600.0px;height: 310.0px;" src="http://img.dxycdn.com/trademd/upload/userfiles/image/2014/08/A1408605159png_small.jpg" alt="">
