Depudecin is a polyketide obtained from the fungus Alternaria brassicicola and having a highly unusual structure of an 11-carbon chain containing two epoxides and six stereogenic centres. It is an inhibitor of histone deacetylase (HDAC) both in vivo and in vitro and also exhibits anti-angiogenic activity.
6-Azidohexanoic acid, a six-carbon saturated fatty acid featuring an ω-terminal azide group, serves as a versatile linker for bioconjugation via copper(I)-catalyzed cycloaddition reactions (click chemistry). This functionality enables its initial acylation to a compound, forming a derivative that can subsequently be conjugated to another compound through click chemistry, facilitating the synthesis of complex molecules.
