Abstract: A chemical investigation of Streptomyces sp. GZWMJZ-662, an endophytic actinomycete isolated from Houttuynia cordata Thunb., has yielded eleven bohemamine dimers (1-11). Notably, the newly identified dibohemamines I–O (1-7) have not been previously reported. Their structures were elucidated through detailed spectroscopic analysis, encompassing high-resolution electrospray ionization mass, nuclear magnetic resonance, infrared radiation, ultraviolet–visible, and electronic circular dichroism spectroscopy. Dibohemamine I (1) exhibited selective cytotoxic effects against the cancer cell lines 786-O and GBC-SD among the 18 cell lines evaluated, with the half-inhibitory concentration values of 3.24±0.20 and 7.36±0.41 μM, respectively.

Key words: Endophytic actinomycete, Secondary metabolite, Dibohemamine, Cytotoxicity
