The development of new immunomodulatory agents can impact various areas of medicine. In particular, compounds with the ability to modulate innate immunological pathways hold significant unexplored potential. Herein, we report a modular synthetic approach to the macrodiolide natural product (?)-vermiculine, an agent previously shown to possess diverse biological effects, including cytotoxic and immunosuppressive activity. The synthesis allows for a high degree of flexibility in modifying the macrocyclic framework, including the formation of all possible stereoisomers. In total, 18 analogues were prepared. Two analogues with minor structural modifications showed clearly enhanced cancer cell line selectivity and reduced toxicity. Moreover, these compounds possessed broad inhibitory activity against innate immunological pathways in human PBMCs, including the DNA-sensing cGAS-STING pathway. Initial mechanistic characterization suggests a surprising impairment of the STING-TBK1 interaction.
Concise Total Synthesis of (?)-Vermiculine through a Rhodium-Catalyzed C2-Symmetric Dimerization Strategy

A short and efficient synthesis of the C2-symmetric antibiotic (?)-vermiculine by utilizing an enantioselective catalytic one-step dimerization methodology as key-step to construct the core structure is reported. The late-stage modifications feature a double metathesis homologation followed by a double Wacker-type oxidation. These key-steps allowed the synthesis of vermiculine in only seven steps, starting from commercially available building blocks.
