Plant found only in the Australian rainforest yields breakthrough cancer drug

Stanford University researchers have discovered a fast and sustainable way to synthesize a promising cancer-fighting compound in the lab. The compound’s availability was limited because its only currently known natural source is a single plant species that grows exclusively in a small region of rainforest in northeastern Australia.

Dubbed EBC-46 and technically called tigilanol tiglate, the compound works by promoting a localized immune response against tumors. The reaction ruptures the tumor’s blood vessels, eventually killing its cancer cells. EBC-46 recently entered human clinical trials after showing an extremely high success rate in treating a type of cancer in dogs.

However, due to its complex structure, EBC-46 did not appear to be synthetically accessible, meaning that no plausible route to practical laboratory manufacture appeared to exist. However, through an ingenious process, Stanford researchers have demonstrated for the first time how to chemically convert abundant plant source material into EBC-46.

As a bonus, this process can produce “analogues” of EBC-46 – compounds that are chemically similar but may prove even more effective and could potentially treat a surprisingly wide range of other serious diseases. These diseases, which include AIDS, multiple sclerosis and Alzheimer’s disease, all share biological pathways that are influenced by the target of EBC-46, a key enzyme called protein kinase C, or PKC.

“We are very pleased to announce the first scalable synthesis of EBC-46,” said Paul Wender, Francis W. Bergstrom Professor in the School of Human Sciences, Professor of Chemistry and courtesy of Chemical and Systems Biology at Stanford, and corresponding author. of a study describing the findings in the journal Nature Chemistry. “The ability to produce EBC-46 in the lab really opens up tremendous research and clinical opportunities.”

The study’s co-authors are Zachary Gentry, David Fanelli, Owen McAteer and Edward Njoo, all graduate students in Wender’s lab, as well as former member Quang Luu-Nguyen.

Wender conveyed the research team’s immense satisfaction with the breakthrough in the synthesis of EBC-46. “If you had visited the lab in the first weeks after their success,” Wender said, “you would have seen my exceptional colleagues smiling from ear to ear. They managed to do what many people thought was impossible.

From a distant region

Tigilanol tiglate originally appeared in an automated drug candidate screening process by Australian company QBiotics. The compound is found naturally in the seeds of the pink fruit of the blushwood tree, Fontainea picrosperma. Marsupials like musk-kangaroos that eat blushwood fruits avoid the seeds rich in tigilanol tiglate, which ingesting them causes vomiting and diarrhea.

Injection of much lower doses of EBC-46 directly into some solid tumors alters cell signaling by PKC. Specifically, EBC-46 is thought to activate certain forms of PKC, which in turn affect the activity of various proteins in cancer cells and trigger an immune response from the host body.

The resulting inflammation leaks the vasculature or blood vessels of the tumor, and this bleeding causes the tumor growth to die. In external cutaneous malignancies, the tumors crust over and fall off, and ways to deliver EBC-46 to internal tumors are being explored.

In 2020, the European Medicines Agency and the United States Food and Drug Administration approved a drug based on EBC-46 sold under the brand name Stelfonta for the treatment of mast cell cancer, the most common skin tumor. common in dogs.

One study showed a 75% cure rate after a single injection and an 88% cure rate after a second dose. Clinical trials have since begun for skin, head and neck, and soft tissue cancers in humans.

Based on these emerging research and clinical needs, coupled with the geographical limitations of parental seeds, scientists considered establishing dedicated plantations of blushwood trees. But this poses a multitude of problems.

For starters, trees need to be pollinated, which means having the right kind of pollinating animals available, as well as planting trees at the correct density and spacing to support pollination. In addition, seasonal and climatic fluctuations as well as pathogens affect the trees. The abandonment of plots for blushwood trees poses other land use problems.

“For sustainable and reliable production of EBC-46 in the quantities we need,” Wender said, “we really need to go the synthetic route.”

Make EBC-46 from scratch

A good starting point for making EBC-46, Wender and his colleagues recognized, is the plant-derived compound phorbol. Over 7,000 plant species worldwide produce phorbol derivatives, and phorbol-rich seeds are commercially inexpensive. The researchers chose Croton tiglium, commonly known as purifying croton, an herb used in traditional Chinese medicine.

The first step in the preparation of EBC-46, explains Wender, is based on daily experience. “You buy a bag of these seeds, and it’s no different from making coffee in the morning,” Wender said. “They grind the seeds and run a hot solvent through them to extract the active ingredient,” in this case a phorbol-rich oil.

After turning the oil into phorbol, the researchers had to find a way to overcome the previously insurmountable challenge of capping a part of the molecule, called the B ring, with carefully placed oxygen atoms. This is necessary for EBC-46 to interact with PKC and alter the activity of the enzyme in cells.

To guide their chemical and biological studies, the researchers relied on instruments from the Stanford Neuroscience Microscopy Service, the Stanford Cancer Institute Proteomics/Mass Spectrometry Shared Resource, and the Stanford Sherlock Cluster for computational modeling.

Using these tips, the team succeeded in adding additional oxygen atoms to the B ring of phorbol, initially via what is called an ene (pronounced “een”) reaction, which is carried out under conditions of flow, the reactants mixing as they pass through the tubes together running. The team then introduced additional cyclic B groups in a gradual and controlled manner to achieve the desired spatial arrangement of the atoms. In all, only four to six steps were required to obtain EBC-46 analogs and a dozen steps to achieve EBC-46 itself.

Wender hopes that the much wider availability of EBC-46 and its PKC-affecting cousin compounds made possible by this breakthrough approach will accelerate the search for potentially breakthrough new treatments.

“As we learn more about how cells work, we learn more about how we can control that functionality,” Wender said. “This control of functionality is particularly important when dealing with cells that go rogue in diseases ranging from cancer to Alzheimer’s disease.”

Wender is also a Fellow of Stanford Bio-X and the Stanford Cancer Institute and a member of Sarafan ChEM-H.
