Role of Pentacyclic Triterpenes in the Management of Neurological Disorders: An Insight into Molecular Mechanisms and Therapeutic Approaches.

Neurological disorders represent major public health concerns globally, as they profoundly affect motor function, memory, and cognitive abilities, thus compromising patients' independence and quality of life. Despite extensive research, current treatment approaches predominantly offer palliative care, failing to hinder disease progression. The rising incidence of these disorders underscores an urgent necessity for more efficacious and disease-modifying therapies. According to findings, pentacyclic triterpenoids exhibit neuroprotective properties by inhibiting neuronal oxidative stress, neuroinflammation, apoptosis, and degeneration, making them promising candidates for targeting the underlying causes of neurodegeneration. Therefore, in this review, we explore natural and synthetic pentacyclic triterpenoids that exhibit neuroprotective effects by modulating signaling pathways, such as HMGB1, TLR4, NLRP3, NF-κB, Nrf2, PI3K, Akt, and CREB, which play crucial roles in regulating cell proliferation, differentiation, and neuronal plasticity. The present literature survey is performed by searching various keywords with several combinations: "pentacyclic triterpenes", "neurological disorders", Parkinson's Disease", "Huntington's Disease", "Alzheimer's Disease", "Multiple sclerosis", "Amyotrophic Lateral Sclerosis" "Epilepsy", "mitochondria dysfunction", "oxidative stress", "preclinical studies", "molecular mechanisms", and "clinical studies". Studies indicates that pentacyclic triterpenoids have a wide range of therapeutic potentials, current findings summarizes existing knowledge and examines the neuroprotective properties and potential molecular mechanisms of pentacyclic triterpenoids related with health benefits and neurological diseases. Available evidence suggests that pentacyclic triterpenoids possess the capacity to impede disease progression and may be beneficial in the treatment of neurological disorders. This review strengthens the understanding of pentacyclic triterpenoids and their molecular mechanisms, while also facilitating pharmaceutical discovery and development for neurodegenerative disorders.
