Herein, we report an efficient approach for exploring the novel anti-cancer mechanism of (-)-ainsliatrimer A, a structurally complex and unique trimeric sesquiterpenoid, through a combined strategy of diverted total synthesis (DTS) and bioorthogonal ligation (TQ-ligation), which allowed us to visualize the subcellular localization of this natural product in live cells.

Herein, we report an efficient approach for exploring the novel anti-cancer mechanism of (-)-ainsliatrimer A, a structurally complex and unique trimeric sesquiterpenoid, through a combined strategy of diverted total synthesis (DTS) and bioorthogonal ligation (TQ-ligation), which allowed us to visualize the subcellular localization of this natural product in live cells. Further biochemical studies facilitated by the pre-target imaging revealed that PPARγ, a nucleus receptor, was a functional cellular target for ainsliatrimer A. We also confirmed that the anti-cancer activity of ainsliatrimer A was caused by the activation of PPARγ.
