Abstract
EBC-46 (aka tigilanol tiglate), has emerged as an exciting anti-cancer agent for the treatment of solid tumors. Intratumoral injection leads to activation of its primary target protein kinase C (PKC), causing increased permeability of tumor endothelial cells and subsequent inflammation to lead to tumor death. Currently, EBC-46 is obtained via extraction of blushwood tree berries, a potentially unsustainable supply tree found only in Queensland, Australia. To ensure a sustainable supply and enable further research into EBC-46, my research has focused on the development of a semi-synthesis of EBC-46 from phorbol, an abundantly available starting material. This work was since been published in Nature Chemistry and a patent has been filed. To obtain phorbol, Croton tiglium seeds are subjected to a robust extraction process that affords upwards of 10 grams of phorbol from 3 kg of seeds. With phorbol in hand, the molecule is walked though a unique oxidation sequence that yields EBC-46 in 12 % overall yield and 12 steps (> 2 grams synthesized). With a sustainable supply of EBC-46, several analogs have been synthesized to probe its structure-activity relationship with PKC. Ongoing efforts continue to elucidate how structural changes to EBC-46 influence its PKC isoform selectivity, potency, and therapeutic potential.
