Yeast chemical genetics to investigate mechanism of action of Pacific natural products.

Yeast-based chemical genetic approaches reveal molecular targets of 17 Pacific natural products, advancing understanding of their mechanisms of action.

• Why it matters: Understanding how natural products work at a cellular level is crucial for developing new medicines and validating traditional uses, yet mechanisms often remain unclear.
• What they did: The study applied yeast methods like haploinsufficiency and homozygous profiling (HIP/HOP) and gene deletion screens to investigate 17 compounds from Pacific fungi, plants, and marine organisms.
• The result: These approaches identified specific molecular targets and pathways affected by the natural products, enabling deeper mechanistic insights and supporting their potential therapeutic development.
