The results of the solution conformational analysis, performed by using Fourier transform infrared absorption and 1H nuclear magnetic resonance, indicate that in chloroform the -Aib-D-Tic-Aib-, -(Aib)2-D-Tic-(Aib)2-, and -L-Pro-D-Tic- sequences fold into intramolecularly H-bonded forms to a great extent. An X-ray diffraction analysis on p-BrBz-(Aib)2-DL-Tic-(Aib)2-OMe monohydrate and p-BrBz-L-Pro-D-Tic-NHMe allows us to conclude that, while the pentapeptide methylester forms an incipient (distorted) 3<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(shè)有歐洲區(qū)子公司和亞洲區(qū)總代理，營銷網(wǎng)點遍及全球20多個國家地區(qū)。MCE經(jīng)過多年努力已成為全球生物活性小分子領(lǐng)域的一流供應(yīng)商， 產(chǎn)品涵蓋癌癥、神經(jīng)科學、抗感染、表觀遺傳學等20個熱門研究領(lǐng)域，PI3K、MAPK等近千個細分靶點，超過4000個活性小分子化合物現(xiàn)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(wù)。</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(chǎn)品都進行嚴格的LCMS和NMR檢驗，其產(chǎn)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(lǐng)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(shù)千種產(chǎn)品在上海有充足備貨，24-48小時內(nèi)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(chǎn)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(gòu)建各種定制型化合物庫。</span><br><br>產(chǎn)品鏈接：<a href="http://www.medchemexpress.cn/_r_-1,2,3,4-tetrahydro-3-isoquinolinecarboxylic-acid.html">www.medchemexpress.cn/_r_-1,2,3,4-tetrahydro-3-isoquinolinecarboxylic-acid.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="">
