An international research team, including scientists from Chelyabinsk State University (ChelSU), has proposed an innovative method for developing pharmaceutical drugs to treat severe mental health conditions. This novel approach is grounded in the use of resveratrol, a natural compound found in grapes and cocoa. The significant findings of their study were published in the scientific journal Biomedicines.
Post-traumatic stress disorder (PTSD) represents a severe psychological consequence stemming from physical and emotional trauma, as well as various catastrophic experiences. Specialists from ChelSU highlight the considerable difficulties encountered in treating PTSD, noting that up to 40% of patients show resistance to currently available medications. Moreover, contemporary treatments for PTSD frequently induce undesirable side effects, such as elevated blood pressure and persistent headaches.
According to the ChelSU researchers, resveratrol (scientifically known as trans-3,4`,5-trihydroxystilbene), a compound naturally produced by plants to defend against stress, holds immense promise for new therapeutic interventions. This organic substance is naturally occurring in grape skins, cocoa beans, and certain types of berries and nuts.
“Resveratrol exhibits potent neuroprotective and antioxidant properties and can function similarly to antidepressants, crucially without their typical adverse effects. However, its widespread therapeutic application has been hampered by its extreme instability: within just an hour of administration, only approximately 5% of the original compound remains unchanged in the body, thereby necessitating the use of prohibitively high doses,” explained Vadim Tseilikman, a distinguished professor at ChelSU`s Faculty of Fundamental Medicine.
In a pioneering effort, the scientists redirected their research focus from resveratrol itself to the products formed during its metabolism within the body, known as metabolites. Their investigations revealed that these metabolites, unlike the parent compound, are remarkably stable and possess their own distinct biological activity, which is comparable to the therapeutic effects of resveratrol itself.
“Previously, resveratrol`s tissue metabolites were dismissed as inert `ballast` that the body simply eliminated, offering no beneficial effects. However, through our meticulous calculations, we have conclusively demonstrated their inherent stability and their capacity to exert their own unique biological actions,” commented Vadim Tseilikman.
Tseilikman underscored the singular importance of this research, pointing out that scientific publications on this specific aspect are exceedingly rare in global literature, and resveratrol`s metabolites themselves were often perceived as an obstacle rather than an opportunity for its therapeutic use.
During the course of their comprehensive study, the researchers meticulously analyzed the concentrations of resveratrol`s tissue metabolites and assessed their correlation with various biological parameters. This analysis successfully confirmed the presence of specific cellular targets that these metabolites interact with.
The authors of the study are confident that these groundbreaking findings significantly advance humanity`s progress toward creating more effective and tolerable treatments for PTSD.
“This discovery addresses a fundamental challenge: while resveratrol`s medical benefits are well-established, its instability has historically impeded drug development. Our innovative approach provides a viable pathway to overcome this critical impediment,” Tseilikman affirmed.
At the current stage, specialists are evaluating two primary methods for the creation of these new pharmaceutical agents: traditional chemical synthesis or advanced biotechnological production.
This extensive international research collaboration also included significant contributions from scientists at the Ruđer Bošković Institute (Croatia), Ural Federal University named after the first President of Russia B. N. Yeltsin, Ufa University of Science and Technology, and Novosibirsk State University.
