Summary: Researchers have discovered that the opioid vortioxetine properly combats glioblastoma, a dangerous brain tumor, in laboratory testing and in animals. This drug, now FDA-approved, crosses the blood-brain barrier and could potentially increase care for glioblastoma people when combined with regular therapy.
The study, using a screen system, identified vortioxetine as a major member, with clinical testing then being planned. While tempting, experts caution against self-medication as individual tests are also important.
Important Information:
- Vortioxetine breaks the blood-brain challenge and stops glioblastoma in lab tests.
- Drugs were remarkably successful against tumor cells, according to researchers.
- Clinical studies are being prepared to test vortioxetine’s influence on glioblastoma people.

Glioblastoma is a very aggressive brain lesion that is currently chronic. Cancer specialists may extend people ‘ life expectancy through businesses, radiation, chemotherapy or surgical treatments. However, half of patients die within twelve weeks of treatment.
Drugs that are effective against , brain tumors , are difficult to find, as many , cancer drugs , often ca n’t cross the , blood-brain barrier , to reach the brain. This limits the choice of possible solutions. Therefore, neuro-oncologists have been diligently looking for better medicines that can reach the brain and get rid of the cyst for a while.
Scientists led by ETH Zurich Professor Berend Snijder have now found a chemical that essentially combats glioblastomas, at least in the experiment: an antidepressant called vortioxetine. Experts know that this inexpensive substance, which has already been approved by companies such as the FDA in the U. S. and Swissmedic, is worthy of crossing the blood-brain challenge.
Sohyon Lee, Snijder’s doctorate and lead author of the study, used pharmacoscopy, a unique verification tool developed by the researchers at ETH Zurich over the years to find it.
The research findings were published in the journal , Nature Medicine.
The ETH Zurich researchers collaborated closely with colleagues from various institutions, particularly with the team led by psychiatrists Michael Weller and Tobias Weiss at the University Hospital Zurich ( USZ).
Testing plenty of elements together
Researchers at ETH Zurich may use pharmacoscopy to instantly check hundreds of active ingredients on living cells from human cancer cells. Their research focused mainly on neuroactive elements that cross the blood-brain challenge, such as drugs, Parkinson’s drugs and antidepressants. In complete, the research team tested upward to 130 different officials on tumor cells from 40 people.
The researchers used imaging methods and system analysis to determine which elements have an impact on the tumor cells. Prior to now, Snijder and his team only had to interpret blood cancer using the pharmacoscopy platform and determine treatment options. The second solid tumors that they have carefully studied using this method with the intention to use existing drugs for novel purposes are glioblastomas.
Lee analyzed new cancer cells from University Hospital Zurich people for the testing. The researchers at ETH Zurich finally processed the cells in a lab and analyzed it using a pharmacoscopy platform. The researchers obtained benefits two days later that demonstrated which agencies worked on the tumor cells and which did not.
Antidepressants remarkably successful
The outcomes demonstrated that some, but not all, of the drugs tested had unanticipated potency against tumor tissue. These medications were particularly effective when they immediately triggered a signaling spiral, which is crucial for neuronal origin cells, and also slowed cell division. Vortioxetine proved to be the most powerful antihistamine.
The experts at ETH Zurich also tested over a million ingredients against glioblastomas using a computer unit. They discovered that the joint signaling cascade of cancer cells and neurons plays a crucial role, which explains why some neuroactive drugs function while others do n’t.
Researchers at the University Hospital Zurich tested vortioxetine on animals with glioblastomas in the final step. In these trials, especially when combined with the current standard therapy, the medicine also demonstrated strong efficacy.
Two therapeutic studies are currently being developed by the ETH Zurich and USZ experts. In one, glioblastoma people may be treated with vortioxetine in addition to standard care ( surgery, chemotherapy, radiation ). Patients will be given a customized medicine selection in the other, which the researchers will use to make their own decisions based on their pharmacoscopy results.
Drug commonly available and inexpensive
” The advantage of vortioxetine is that it is secure and very cost-effective”, says Michael Weller, Professor at the University Hospital Zurich, Director of the Department of Neurology and co-author of the investigation.
The drug has already been approved, so it wo n’t have to go through a lengthy approval process, and it could soon replace the deadly brain tumor’s standard treatment. He anticipates that doctors will soon be ready to use it.
He warns patients and their families against consuming vortioxetine on their own and without health care, though. Clinical trials are necessary because we do n’t yet know whether the drug works in humans or what dosage is needed to treat the tumor. Self-medicating would be an unfathomable risk”.
Snijder, also, warns against rushing to use the opioid on glioblastomas, saying,” So far, it’s only been proven efficient in cell cultures and in animals”.
However, he believes that this review has achieved an appropriate outcome. ” We started with this terrible , tumor , and found existing medications that battle against it. We show how and why they work, and rapidly we’ll be able to check them on people”.
This will be the first time in recent years that an energetic substance has been found to increase the treatment of glioblastoma if vortioxetine proves to be effective.

Abstract
Reusable neuroactive drugs with dangerous anti-glioblastoma activity are identified with high-throughput.
Glioblastoma, the most violent major brain tumor, has a dreadful outcome, but systemic therapy is limited to DNA-alkylating chemotherapies. Investigating glioblastoma’s developmental and neurophysiological risks may lead to novel therapeutic approaches.
We used a scientifically congruent and single-cell resolved system to carefully screen repurposable neuroactive substances in glioblastoma individual surgery material.
In addition to profiling more than 2, 500 ex vivo medicine responses from 27 patients, 132 drugs with class-diverse neuroactive properties with powerful anti-glioblastoma effectiveness that were validated across model systems were profiled.
AP-1/BTG-driven glioblastoma reduction was the subject of intelligible chemical machine learning, enabling expanded in silico screening of more than 1 million compounds with great patient validation accuracy.
Deep multimodal profiling confirmed Ca2+-driven AP-1/BTG-pathway induction as a neuro-oncological glioblastoma vulnerability, epitomized by the anti-depressant vortioxetine synergizing with current standard-of-care chemotherapies in vivo.
These findings provide a useful framework for treating glioblastoma with a neural etiology based on its neural etiology.
