This research topic focuses on the discovery, evaluation, and optimization of novel or repurposed therapeutic agents, addressing diseases with high prevalence (e.g. cardiovascular disorders) or poor prognosis (e.g. triple-negative breast cancer, melanoma).
-
a) Novel Therapeutic Strategies and Drug Repurposing
Preclinical pharmacodynamic studies identified several promising bioactive compounds:
- Peptide-based products derived from brewery by-products demonstrated vasodilatory properties, supporting their potential to reduce cardiovascular risk.
- Multiple classes of anticancer agents were identified, including metal-associated biogenic amines, polyphenols from plants and fruits, and isoxazole derivatives, showing selective antitumor activity in aggressive and drug-resistant cancer models.
- Pharmacokinetic characterization of palladium–polyamine complexes supported their potential as future anticancer agents.
- Oral pharmacokinetics of bioactive peptides were investigated, addressing first-pass metabolism and enterohepatic cycling, with the aim of improving bioavailability and therapeutic efficacy.
- A major achievement was the identification of extracellular biomarkers associated with drug resistance in triple-negative breast cancer, providing new avenues for treatment stratification and monitoring.
-
b) Resistance-Associated Diseases: Innovative Therapeutic Strategies
Addressing drug resistance and disease refractoriness is a key priority:
- In cancer, selective antitumor activity of novel metal-based compounds was demonstrated in triple-negative breast cancer models resistant to platinum-derived drugs.
- In diabetes, mechanistic studies revealed that disease progression enhances RAS activation, increasing AngII levels and driving gastrointestinal remodeling. These findings supported the submission of an international patent for the prevention and treatment of diabetes-associated gastrointestinal complications through drug repurposing.
- Combination therapeutic strategies are being explored, integrating polyamine–metal agents, endogenous nucleosides (e.g. adenosine), and plant-derived polyphenols to enhance efficacy and overcome resistance.
- Extending beyond human health, an innovative line of research identified resistance profiles to nematode infection in Arabidopsis thaliana, Zea mays, and Pinus pinaster. These findings open the door to sustainable phytopharmaceutical strategies aimed at improving crop and forest resilience through the use of naturally resistant species.
