Protective effects of DL‑3‑n‑butylphthalide in the lipopolysaccharide‑induced mouse model of Parkinson's disease.

DL‑3‑n‑butylphthalide (NBP) is extracted from rapeseed and exhibits multiple neuroprotective effects, exerted by inhibiting the inflammatory process, including reducing oxidative stress, improving mitochondrial function and reducing neuronal apoptosis. The present study aimed to investigate the neuroprotective effects of NBP in a lipopolysaccharide (LPS)‑induced mouse model of Parkinson's disease (PD). The behavior of mice was assessed using the rotarod test and open‑field test, the amount of tyrosine hydroxylase in the substantia nigra pars compacta was evaluated by immunohistochemistry, and the levels of phosphorylated c‑Jun N‑terminal kinase (JNK), mitogen‑activated protein kinase 14 (p38) and extracellular signal‑regulated kinase 1 were determined by western blotting.

Therapeutic effects of paeonol on methyl-4-phenyl-1,2,3,6-tetrahydropyridine/probenecid-induced Parkinson's disease in mice.

Paeonol is a major phenolic compound of the Chinese herb, Cortex Moutan, and is known for its antioxidant, anti-inflammatory and antitumor properties. The present study was designed to investigate the therapeutic potential and underlying mechanisms of paeonol on a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine/probenecid (MPTP/p)-induced mouse model of Parkinson's disease (PD). MPTP (25 mg/kg), followed by probenecid (250 mg/kg), was administered via i.

Neuroprotective effects of piperine on the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced Parkinson's disease mouse model.

Parkinson's disease (PD) is second only to Alzheimer's disease as the most common and debilitating age-associated neurodegenerative disorder. Currently, no therapy has been shown to unequivocally retard or arrest the progression of the disease. The aim of the present study was to investigate the protective effect of piperine on the 1-methyl-4-phenyl-1,2,3,6‑tetrahydropyridine (MPTP)-induced Parkinson's mouse model.
