The target octapeptide CCK-8 is the minimum active sequence with the same biological activity as naturally occurring cholecystokinin and is ... Metabolism of deuterated erythro-dihydroxy fatty acids in Saccharomyces cerevisiae: Enantioselective formation and characterization of hydroxylactones [作者：Garbe, LA; Morgenthal, K; Kuscher, K; Tressl, R,期刊：Helvetica Chimica Acta, 页码：993-1007 , 文章类型： Article，,卷期：2008年91-6] Epoxides of fatty acids are hydrolyzed by epoxide hydrolases (EHs) into dihydroxy fatty acids which are of particular interest in the mammalian leukotriene pathway. In the present report, the analysis of the configuratio... A mild and efficient method for N-arylnucleobase synthesis via the cross-coupling reactions of nucleobases with arylboronic acids catalyzed by simple copper salts [作者：Tan, L; Yue, Y; Zhang, J; Chen, SY; Yu, XQ,期刊：Helvetica Chimica Acta, 页码：1008-1014 , 文章类型： Article，,卷期：2008年91-6] A simple and efficient copper-salt catalyzed N-arylation of nucleobases is reported. In a mixed solvent of MeOH and H2O, the coupling products were obtained in moderate to excellent yields at room temperature within a sh... Three new isoflavonoids from the aerial parts of Ammopiptanthus mongolicus [作者：Tian, XM; Chen, SZ; Tang, L; Tu, PF,期刊：Helvetica Chimica Acta, 页码：1015-1022 , 文章类型： Article，,卷期：2008年91-6] Three new isoflavonoids, namely (+/-)-ammopiptanine A (1), ammopiptanine B (2), ammopiptanoside A (3), together with 13 known compounds, were isolated from the aerial parts of Ammopiptanthus mongolicus. Their structures ... Lignanamides and sesquiterpenoids from stems of Mitrephora thorelii [作者：Ge, F; Tang, CP; Ye, Y,期刊：Helvetica Chimica Acta, 页码：1023-1030 , 文章类型： Article，,卷期：2008年91-6] The first phytochemical investigation on stems of Mitrephora thorelii led to the isolation of three new lignanamides, thoreliamides A-C (1-3), and a new sesquiterpenoid, thorelinin (4), together with ten known compounds.... Two new nitrone alkaloids from Huperzia serrata [作者：Gao, WY; Li, YM; Jiang, SH; Zhu, DY,期刊：Helvetica Chimica Acta, 页码：1031-1035 , 文章类型： Article，,卷期：2008年91-6] Two new nitrone alkaloids were isolated from the whole plant of Huperzia serrata (THUNB.) TREV. They are both phlegmarine-type lycopodium alkaloids with a nitrone moiety. Their structures were elucidated on the basis of ... Secondary metabolites from the leaves of Litsea lii var. nunkao-tahangensis [作者：Wang, TA; Cheng, MJ; Lee, SJ; Yang, CW; Chang, HS; Chen, IS,期刊：Helvetica Chimica Acta, 页码：1036-1044 , 文章类型： Article，,卷期：2008年91-6] Investigation of the leaves extract of Litsea lii var. nunkao-tahangensis led to the isolation of five new butanolides, litsealiicolide A (1), isolitsealiicolide A (2), litsealiicolide B (3), isolitsealiicolide B (4), an...
