<a href="https://www.medchemexpress.com/Istaroxime.html">Istaroxime</a>产品描述：Istaroxime is a potent inhibitor of <b>Na<sup>+</sup>,K<sup>+</sup>-ATPase</b> with <b>IC<sub>50</sub></b> of 0.11 μM.IC50 & Target: IC50: 0.11 μM (Na<sup>+</sup>,K<sup>+</sup>-ATPase)<sup>[1]</sup><i><b>In Vitro:</b></i> Istaroxime acting as a positive inotropic compound through the inhibition of the Na<sup>+</sup>,K<sup>+</sup>-ATPase<sup>[2]</sup>. Istaroxime (PST2744) inhibits the Na<sup>+</sup>/K<sup>+</sup>-ATPase activity from dog kidney with an IC<sub>50</sub> value of 0.43 ± 0.15 μM. Inhibition of Na<sup>+</sup>/K<sup>+</sup>-ATPase activity in preparations from guinea pig kidney yielded potencies of 8.5 μM for PST2744<sup>[3]</sup>.<i><b>In Vivo:</b></i> Istaroxime (PST2744) induces a progressive increase in +dP/dt<sub>max</sub> throughout the infusion that reaches 80% (ED<sub>80</sub>) at the cumulative dose of 1.89±0.37 mg/kg and a peak of 140±3.5% at the dose (ED<sub>max</sub>) of 4.88±0.6 mg/kg<sup>[3]</sup>.<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);">公司介绍：MedChemExpress(MCE)专注于各种抑制剂、激动剂、API及化合物库，总部位于美国新泽西，分别在瑞典和上海设有欧洲区子公司和亚洲区总代理，营销网点遍及全球20多个国家地区。MCE经过多年努力已成为全球生物活性小分子领域的一流供应商， 产品涵盖癌症、神经科学、抗感染、表观遗传学等20个热门研究领域，PI3K、MAPK等近千个细分靶点，超过4000个活性小分子化合物现货，以及GPCR、API、离子通道等超过20种不同类型的化合物库，同时提供从毫克到千克的专业定制合成服务。</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 对每批产品都进行严格的LCMS和NMR检验，其产品已被全球近万名客户广泛使用并发表大量文章、专利；</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 定期增加各领域热门抑制剂、激动剂，不断扩增已有化合物库，以满足最新的科研需求；</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);">数千种产品在上海有充足备货，24-48小时内送达客户；</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);">大量产品提供免费试用装；</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);">已为全球多个知名企业、院校构建各种定制型化合物库。</span><br><br>产品链接：<a href="http://www.medchemexpress.cn/istaroxime.html">www.medchemexpress.cn/istaroxime.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="">
