From Tradition to Biochemical Innovation: Phytobioactive Compounds in Modern Neuropharmacology

The therapeutic potential of herbal and natural compounds has long been recognized; meanwhile, the role of these compounds in neuropharmacology is gaining increasing attention due to their promising biochemical effects. The rising prevalence of neurodegenerative disorders, including Alzheimer’s disease, Parkinson’s disease, and depression, has underscored the need for novel, effective treatments with minimal side effects. Notably, natural products derived from plants, fungi, and other organisms offer a vast array of bioactive molecules that can interact with neuronal pathways to modulate cognitive function, neuroprotection, and synaptic plasticity. Furthermore, recent advancements in neuropharmacology have revealed the molecular mechanisms underlying the therapeutic efficacy of herbal compounds, such as flavonoids, alkaloids, terpenoids, and phenolic acids, in mitigating oxidative stress, inflammation, and neuroinflammation. Moreover, these compounds have shown promise in enhancing neurotransmitter systems, such as serotonin, dopamine, and acetylcholine. The integration of cutting-edge technologies, including high-throughput screening, metabolomics, and molecular docking, has facilitated the discovery of novel natural neuroprotective agents. Artificial Intelligence (AI) and nanotechnology are transforming the use of phytobioactive compounds in modern neuropharmacology by enabling precise prediction of molecular targets, optimizing drug-likeness, and enhancing mechanistic understanding. Additionally, nanocarriers such as polymeric nanoparticles, liposomes, and nanoemulsions, are improving the brain delivery, stability, and bioavailability of plant-derived molecules that traditionally suffer from poor pharmacokinetics. Together, these technologies can accelerate the development of next-generation neuroprotective therapeutics from natural products with greater efficiency, specificity, and translational potential. This review provides a comprehensive overview of the latest biochemical innovations in herbal and natural compounds for neuropharmacology, emphasizing the potential of these compounds as safe and effective alternatives or adjuncts to conventional neurotherapeutics.
