5-alkyl-1,2,3,4-tetrahydroquinolines (5aTHQs) bearing different side chains have been isolated from a combined culture of Streptomyces nigrescens HEK616 and Tsukamurella pulmonis TP-B0596. The chemical structures including the absolute configuration were elucidated by spectroscopic analysis and total synthesis. 5aTHQs inhibited the growth of wild-type fission yeast while only weakly inhibiting the growth
八新的5-烷基-1,2,3,4-四氢喹啉(5aTHQs)带有不同侧链已从的组合培养物中分离链霉菌变黑HEK616和冢村pulmonis TP-B0596。通过光谱分析和全合成阐明了包括绝对构型在内的化学结构。5aTHQs抑制了野生型裂变酵母的生长,而仅微弱地抑制了几种合成过早麦角甾醇的突变菌株的生长。这些结果表明5aTHQs是可能针对细胞膜的新型抗真菌药。
