Statins as neuroprotectants: a comparative in vitro study of lipophilicity, blood-brain-barrier penetration, lowering of brain cholesterol, and decrease of neuron cell death

Topic: Gut, metabolism and diet
There is growing evidence to support the hypothesis that statins may act as neuroprotectants in several neuropathological conditions, including Alzheimer's disease. The mechanisms for neuroprotection are only partially understood, however, and pleiotropic phenomena could be involved. We have made a comparative study of 9 statins (lovastatin, mevastatin, pravastatin, simvastatin, cerivastatin, atorvastatin, fluvastatin, pitavastatin, and rosuvastatin), analyzing several parameters that could be related to neuroprotection, such as chemical structure, lipophilicity, potential blood-brain-barrier penetration (BBB), 3-hydroxy-3-methylglutaryl co-enzyme A reductase inhibition, cholesterol modulation in neurons, glia, and human hepatocyte cell lines, and protection against neurodegeneration caused by tau hyperphosphorylation induced by okadaic acid. Our results indicate that monacolin J derivatives (natural and semi-synthetic statins) are the best candidates for the prevention of neurodegenerative conditions due to their higher potential BBB penetration capacity, cholesterol lowering effect on neurons with a satisfactory safety profile, and in vitro protection against cell death caused by okadaic acid in culture. Among the nine statins studied, simvastatin presented the best characteristics for preventing neurodegenerative conditions.
Key findings
- Our results indicate that monacolin J derivatives (natural and semi-synthetic statins) are the best candidates for the prevention of neurodegenerative conditions due to their higher potential BBB penetration capacity, cholesterol lowering effect on neurons with a satisfactory safety profile, and in vitro protection against cell death caused by okadaic acid in culture.

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
