Therapeutic modalities undergoing preclinical/clinical trials for neurodegenerative diseases.

Compound/ChemicalDiseaseEffect

CoQ10PDReduces the loss of DA neurons in the SNpc (Cleren et al., 2008, [12], Somayajulu-Niţu et al., 2009, [13])

TrehalosePDAutophagy-mediated, short-term reduction of phosphorylated tau and β-amyloid plaques in parkin (PK−/−/TauVLW) mouse model (Rodríguez-Navarro et al., 2010, [14])

SR-3306 (JNK inhibitor)PD Reduces the loss of dopaminergic cell bodies in the SNpc and their terminals in the striatum (Crocker et al., 2011, [15])

CurcuminPD Reduces synuclein toxicity, intracellular ROS, and apoptosis in neuroblastoma cells (Dinkova-Kostova et al., 2010, [16])

ADBlockes Aβ aggregation (Guo et al., 2010, [17])
Inhibites Aβ insult (Ono et al., 2004, [18])
Protects Sprague-Dawley rats from Aβ-induced damage (Frautschy et al., 2001, [19])
Inhibits neuroglial cell proliferation (Ambegaokar et al., 2003, [20])
Inhibits Aβ-induced cytochemokine gene expression and CCR5-mediated chemotaxis of THP-1 monocytes by modulating EGR-1 (Giri et al., 2004, [21])
Inhibits α-synuclein aggregation (Pandey et al., 2008, [22])

Methylene blueAD Inhibits cGMP pathway
Attenuates amyloid plaque formation and neurofibrillary tangles (Wischik et al., 2008, [23] Oz et al., 2009, [24])

Viral vector Aβ cDNA (oral vaccination)ADAlleviates progressive cognitive impairment with decreased Aβ deposition, insoluble Aβ, soluble Aβ oligomer, microglial attraction, and synaptic degeneration induced in brain regions (Mouri et al., 2007, [25])

AL-108ADStabilizes microtubules and blocks Aβ aggregation (Masters and Beyreuther, 2006, [26])

Curcumin derivativeStrokeEnhances memory, contributes to neurotrophic activity, and prevents cell death (Lapchak et al., 2011, [27])
