Six new pimprinine alkaloids (-), including four dimers, dipimprinines A-D (-), and two monomers, (±)-Pimprinol D (), and pimprinone A (), along with six known congeners (-), were isolated from a soil-derived actinomycete sp. NEAU-C99. Structures of the new compounds were elucidated by extensive spectroscopic analyses, single-crystal X-ray diffractions, and ECD calculations. Dipimprinines A-D (-) showed weak cytotoxic activities against five tumor cell lines, including HL-60, SMMC-7721, A-549, MCF-7, and SW-480, with IC values ranging from 12.7 to 30.7 μM.
从一株土壤来源的放线菌新种NEAU-C99中分离出6个新的匹普林宁生物碱（-），包括4个二聚体，双匹普林宁A-D（-），以及2个单体，（±）-匹普林醇D（）和匹普林酮A（），同时还分离出6个已知的同系物（-）。通过广泛的光谱分析、单晶X射线衍射和电子圆二色（ECD）计算确定了新化合物的结构。双匹普林宁A-D（-）对包括HL-60、SMMC-7721、A-549、MCF-7和SW-480在内的5种肿瘤细胞系显示出较弱的细胞毒性活性，IC值范围为12.7至30.7μM。
