Yatakemycin: total synthesis, DNA alkylation, and biological properties

DNA-binding small molecules are an important source of anticancer therapeutics that display a diverse array of mechanisms of action. Synthetic studies on the new DNA-alkylating natural product yatakemycin, detailed in this Highlight, have served to reassign its structure, assign the absolute stereochemistry, and provide access to yatakemycin and a series of structural analogues for biological evaluation. Studies on the DNA alkylation properties of (+)-and ent-(-)-yatakemycin and related analogues have demonstrated the enhanced DNA alkylation properties of this class of agents and provided insight into their interaction with DNA.
