Background: Parkinson's disease (PD) is one of the most common neurodegenerative disorders. One of the underlying mechanisms of the disease is the accumulation of α-synuclein protein aggregates, including amyloids and Lewy bodies in the brain, resulting in the death of dopaminergic cells in the substantia nigra. The current treatments for PD are mainly focused on replacing dopamine. However, if these medications are stopped, the severity of PD will increase. Moreover, the drugs used for the treatment of PD are associated with considerable side effects and dietary restrictions. Therefore, necessary studies to develop more effective medications for PD seem to be indispensable. To prevent the progression of PD, avoiding the development of α-synuclein amyloids could be proposed. Methods: In this study, the effects of three last-generation nanotube-based structures on α-synuclein amyloid formation were investigated for the first time employing Molecular Dynamics (MD) simulation tools. Molecular dynamics provide a deep insight into atomic interactions and can well study α-synuclein amyloid formation at the atomic and molecular scales.Results: The molecular study results indicated that all of the nanotubes studied in this work, had strong energy interactions with α-synuclein. Therefore, nanotubes using phosphorus, nitrogen and boron dopants, have great potential to prevent α-synuclein amyloid formation. Among these nanotubes, phosphorus-doped carbon nanotube (P-CNT) has the most substantial interactions with α-synuclein. The P-CNT caused more hydrogen bonds to be formed between water and α-synuclein molecules. This phenomenon leads to a decrease in the compactness, stability, and contact area of α-synuclein proteins, which results in considerable changes in the secondary structure of α-synuclein.Conclusions: Doping nanotubes especially P-CNT could be very effective for preventing the α-synuclein amyloid formation and hence, halting the progression of PD. This molecular study paves the way for the use of the Doping nanotubes in the treatment of PD. These structures are highly tunable and flexible. Therefore, the results of this work can be developed to computational, experimental and clinical levels.

Nanoparticles are useful for increasing drug stability, solubility, and availability. The small molecule baicalein inhibits fibrillation, and detoxifies aggregates of α‐synuclein (αSN) associated with Parkinson's disease (PD), but it suffers from instability, low solubility and consequent low availability. Here it is demonstrated that incorporation of baicalein into zwitterionic nanoliposomes (NLP‐Ba) addresses these problems. NLP‐Ba inhibits αSN fibril initiation, elongation, secondary nucleation, and also depolymerizes mature fibrils more effectively than free baicalein and prevents soluble αSN aggregates from seeding new fibrils. Importantly, NLP‐Ba perturbs oligomers’ capacity to permeabilize the membrane. The interaction between NLP‐Ba and αSN is confirmed by different biophysical techniques. This nanosystem crosses the blood‐brain barrier in vitro and is effective against rotenone neurotoxicity in vivo. The effect of NLP‐Ba on αSN fibrillation/cytotoxicity is attributed to a combination of free baicalein and empty NLPs. The results indicate a neuroprotective role for NLP‐Ba in decreasing αSN pathogenicity in PD and highlight the use of nanoliposomes to mobilize poorly soluble hydrophobic drugs.

Parkinson's disease (PD) is a chronic, and highly neurodegenerative disorder with complex pathological processes. The features for neuropathological identification of PD include α‐synuclein (α‐syn) protein aggregates, oxidative stress, metal ion dyshomeostasis, neurotransmitter deficiencies, and mitochondrial dysfunction. Currently, no definite treatment paradigm can completely cure PD patients, which is increasing globally over the past few decades. The existence of the blood‐brain barrier (BBB) restricts the conventional treatment processes and makes the therapeutic delivery to the brain a bit more challenging. Therefore, developing new useful medicines for improving brain distribution is vital to overcome BBB and helping the early diagnosis and treatment of PD. In this review, the current limitations of conventional drugs are highlighted and the development of new medicines to overcome such limitations is covered. This work will provide insight into the direction for designing novel efficient nanomedicines for the early diagnosis and treatment of PD.
