Four new quinone-containing metabolites, halawanones A-D (1-4), have been isolated along with the known compound nanaomycin D (5) from liquid cultures of a streptomycete obtained from a sediment sample collected in the estuarine environment at the mouth of Halawa stream, Oahu. The structures of the new compounds were determined through the interpretation of spectral data. The absolute stereochemistries were determined using a combination of CD and NMR.
从瓦胡岛哈拉瓦溪河口河口环境采集的沉积物样本中获得的链霉菌液体培养物中，分离出了四种新的含醌代谢产物，即哈拉瓦酮A-D（1-4），以及已知化合物纳那霉素D（5）。通过光谱数据解析确定了新化合物的结构。使用圆二色光谱（CD）和核磁共振（NMR）相结合的方法确定了绝对立体化学结构。
