Effects of MP in diabetes, PD, and ED (animal model)

S.No.First citationYear of publicationCountryTargeted diseaseExperimental modelDoseMajor finding
1Baroli et al. [24]2019ItalyPDDrosophila melanogaster model (fruit fly)Not applicableBeneficial effect on the oxidative stress conditions, rescues the mitochondrial functioning from oxidative stress
2Solari et al. [25]2018ItalyPDDrosophila melanogaster model (fruit fly)Not applicableMPE treatment rescued the crop muscle parameters and also the mitochondrial morphology
3Johnson et al. [26]2018USAPDDrosophila melanogaster model (fruit fly)12.5–50 g/mLMPE contains bioactive compounds, beyond leva-dopa, which may impart neuroprotective effects against PD
4Singh et al. [27]2016IndiaPDSwiss albino male mice (8–10 week old, 30–45 g)48 mg/kg body wtSignificantly decreased the elevated levels of oxidative stress found in Parkinsonian mice
5Poddighe et al. [28]2014ItalyPDDrosophila melanogaster model (fruit fly)Not applicableSuggesting that its effects cannot only depend upon its leva-dopa content but support the clinical observation of MPE as an effective medication with intrinsic ability to delay the onset of chronic leva-dopa-induced long-term motor complications
6Jansen et al. [29]2014UKPDDrosophila melanogaster model (fruit fly)Not applicableNo significant effects were observed
7Yadav et al. [30]2014IndiaPDSwiss albino male mice, 25 ± 5 g wt25, 50, 100, 150, and 200 mg/kg body-wtDecreasing oxidative stress and possibly implementing neuronal and glial cell crosstalk
8Yadav et al. [31]2013IndiaPDSwiss albino male mice weighing 25 ± 5 gram25, 50,100, 150, and 200 mg/kg body-wtSignificantly reduced the PQ induced neurotoxicity as evidenced by decrease in oxidative damage, physiological abnormalities, and immunohistochemical changes in the parkinsonian mouse
9Lieu et al. [32]2012USAPDFourteen adult (6–9 kg) rhesus (Macaca mulatta) and two cynomolgus (Macaca fascicularis) monkeysMPEP + CD (4.5 g/25 mg)Distinctive neurophysiological findings in the basal ganglia and the ability to ameliorate parkinsonism without causing dyskinesias
10Lieu et al. [33]2010USAPDFemale Sprague-Dawley rats (250–400 g)80 mg/kg MPE (group 2), and 40 mg/kg MPE (group 3) with 15 mg/kg of BZ (MPE + BZ)MP contains water-soluble ingredients that either have an intrinsic DDCI-like activity or mitigate the need for an add-on DDCI to ameliorate parkinsonism
11Dhanasekaran et al. [34]2008USAPDMale Sprague-Dawley rats (200–225 g)Varying doses with different combinationsInhibited the oxidation of lipids and deoxyribose sugar by exhibiting antioxidant and metal chelating effects
12Tharakan et al. [35]2007USAPDMale Sprague-Dawley rats (200–225 g)Varying doses with different combinationsMPCP has shown anti-parkinson and neuroprotective effects in animal models of PD that are superior to synthetic levo-dopa. The copper chelating property may be one of the mechanisms by which MPCP exerts its protective effects on DNA
13Manyam et al. [36]2004USAPDSprague-Dawley rats2.5, 5.0, or 10.0 g/kg/dayAntiparkinson effect may be due to components other than levo-dopa or that it has a levo-dopa enhancing effect
14Majekodunmi et al. [9]2011NigeriaDiabetesWistar rats (180–240 g) and albino mice (16–20 g) of both sexesMethanol and ethanol fractions of MPA single dose of the ethanolic extract of MP resulted in a significant reduction in the blood glucose level, reducing the weight loss associated with diabetes
15Rathi et al. [37]2002IndiaDiabetesRats100, 200, and 400 mg/kg/dayMP had no significant effect
16Choowong-In et al. [38]2021ThailandEDNinety-six adult male (n = 48) and female (n = 48) ICR mice (10 weeks, weighing 35–40 g)600 mg/kgImprove the sexual performances and reproductive parameters especially functional proteins in testis, epididymis, and sperm
17Seppan et al. [39]2020IndiaEDMouse model200 mg/kg body weightRestoring aging induced structural and functional impairment in dorsal nerve of the penis and ED
18Duangnin et al. [11]2017ThailandEDMale Wistar rats of 250–300 g, 6–8 weeks old20 mg/kg and 200 mg/kg body weightPolar fraction of MP is able to upregulate the expression of ED-related genes including eNOS and nNOS in vitro which subsequently promotes nitric oxide production and maintains intracellular cyclic guanosine monophosphate levels
19Goswami et al. [40]2012IndiaEDMale Wistar rats weighing 200–250 g50 ug/mLMethanolic extract of MP failed to inhibit Rho-kinase 2
