Major cause of proteopathies is the accumulation of unwanted mutant and aberrant proteins. We know that imperfect ageing is one of chief risk factor for most neurodegenerative diseases. Neurodegenerative diseases are characterized by mutant misfolded protein aggregates developing neural stress and debilitating several neuronal processes. Reducing the levels of these abnormal proteins using various natural compounds can be a promising possible therapeutic strategy. But the advancement of natural compound-based therapies in neurodegeneration and imperfect ageing treatment has been impeded by different challenges and unknown molecular patho-mechansim. The complexity in the causative factors generating protein aggregates in neurons and their respective path towards cell death is high, making it a difficult to treat disorder. Several plant based compounds have proven to promote different neuronal homeostasis mechanisms. However, there is a pressing necessity to screen, find and develop cost-effective natural compound-based new therapeutic interventions which can be useful for clinical purposes in treating neurodegenerative ailments. It is critical to discuss and elaborate the applications of few important natural compounds and their connections with following mechanisms: protein disposal machineries, apoptosis, neuroinflammation, neuronal development, synaptogenesis and neural homeostasis. This article summarizes the current knowledge and discusses the unanswered questions linked with the natural compounds and their promising therapeutic avenues primarily focusing on neurodegenerative diseases and defective neurobiological mechanisms.
