Abstract

Pathophysiologies underlying the Parkinson's disease is oxidative stress, can be treat with antioxidants from natural sources, including Piper cubeba L. Flavonoids are reported as antioxidants. This study aimed to analyse the flavonoids content and antiparkinson activity from the ethanolic extract of cubeb fruits (EECF), ethyl acetate fraction of ethanolic extract of cubeb fruits (EAFEECF), n-hexane fraction of ethanolic extract of cubeb fruits (NHFEECF). This research is an experimental study with a post test only control group design. Eighty four rats were divided into 14 groups. Group 1 is a normal group, group 2-3 are negative controls which were given aquadest and olive oil, respectively. Positive control groups, 4 and 5 were given levodopa 27 mg/kgBW and vitamin E 180 IU/kgBW, respectively. Group 6-14 were given EECF, EAFEECF, and NHFEECF at doses 150, 300, 600 mg/kgBW. Group 2-14 were induced with haloperidol 2 mg/kgBW intraperitoneally 45 minutes after administration of the material tests. The materials are given once a day for 7 days. The length of time the rats can hold on to the rotarod was tested on days 0, 4, 7, 11, 14. The curve showed the data on the survival time of rats on a rotarod versus time, then the AUC0-14 was calculated using the trapezoidal method. The AUC0-14 were analyzed using Mann Whitney test at 95%CI. The flavonoids content were analysed using TLC. The results showed that the EECF, EAFEECF, and NHFEECF contained flavonoids, and antiparkinson activity except for the NHFEECF at doses 150 and 600 mg/kgBW.

Abstract

Class 1 and 2 histone deacetylase inhibitors (HDACI) have been reported as novel therapeutic approaches to treat neurodegenerative disorders, depression, anxiety, and cognitive deficits. HDACI ameliorated deficits in cognition and stress-related behaviors in a wide range of neurologic and psychiatric disorders. Preclinically, behavioral bioassay can be used to predict the influence of new compounds for treatment of these illnesses. Curcumin and its new analogues PGV-0 and PGV-1 have been reported to inhibit HDAC2. However, reports regarding the effect of curcumin and its analogues on memory and cognitive function, anxiety, and social interaction behavior are as yet to be examined. Mice were divided into control and treated groups. Brain disorder was induced by oral administration of 10% ethanol in sodium-CMC for 7 days. Curcumin, PGV-0, PGV-1, and sodium butyrate (as positive control) were then given orally once a day for 21 days. The behavior tests of social interaction, open field, radial 8-arm-maze, and passive avoidance were performed on day 29. To increase dissolution and bioavailability of the compounds, they were formulated in a self-nano emulsifying drug delivery system (SNEDDS). Brains were isolated and analyzed using PCR to investigate the expression of genes related to neurobehavioral disorders hdac2, trkB, and bdnf. In different doses, curcumin, PGV-0, and PGV-1 increased social interaction capability, declined anxiety level, and improved long-term memory and cognitive function. The mechanism proposed is: HDACI curcumin and its analogues (PGV-0 and PGV-1) that keep the histone protein in acetylation state increase bdnf expression. The increased trkB expression is increasing the activation of the bdnf gene because trkB is the primary receptor of bdnf that supports the survival of existing neurons and encourages the growth and differentiation of new neurons and synapses. Thus, those mechanisms could improve long-term memory and cognitive function, increase social interaction, and reduce anxiety in ethanol-induced mice with brain disorders.
