Ion, and played a neuroprotective part by means of mitochondrial pathway, antioxidant, anti-inflammatory and anti-apoptotic effects (Costa et al., 2018; Song et al., 2018), which mainly regulated JNK3, FAS, FasL, caspase-8, Bid, caspase-3 and cyto C, p62, Bax/Bcl-2, LC3II/LC3I (Li et al., 2019; Liu et al., 2013; Yin et al., 2020; Zhang, J. et al., 2019). Moreover, astragaloside IV could also inhibit neutrophil adhesion related molecules (TNF-a, NF B, IL-1, etc.) to play an anti-inflammatory role, and had neuroprotective effect on cerebral I/R injury (Li et al., 2012).Frontiers in Pharmacology | www.frontiersin.orgApril 2021 | Volume 12 | ArticleXie et al.Neuroprotection on All-natural ProductsBMECs by tetramethylpyrazine phosphate and borneol combination involved 5-HT7 Receptor Inhibitor custom synthesis anti-oxidation, apoptosis inhibition, and angiogenesis (Yu et al., 2019).glutamate-induced HT22 neuronal cell death (Dong et al., 2019; Jin, M. L et al., 2014).Polysaccharides NEUROPROTECTIVE Function OF OTHER COMPOUNDS IN ISCHEMIC BRAIN INJURY EmodinEmodin (Figure 5F), 1,3,8-trihydroxy-6-methylanthraquinone, is really a naturally occurring anthraquinone derivative and an active component from Polygonum multiflorum Thunb. Rheum palmatum L. and so on, which have been used extensively in Asia in therapy of numerous diseases (Dong, X. et al., 2016). Emodin has been demonstrated to possess a wide spectrum of pharmacological effects, which include anti-viral, anti-bacterial, antiallergic, anti-osteoporotic, immunosuppressive, neuroprotective activities (Dong, W. et al., 2016; Leung et al., 2020; Xue et al., 2020). In truth, the neuroprotective effect of Polygonum multiflorum Thunb was 1st published in 2000 (Gu et al., 2000) plus the neuroprotective effect of emodin was published in 2005 when its potential to interfere with the release of glutamate was identified as a process of neuroprotection (Gu et al., 2005). On top of that, emodin may well afford a significant neuroprotective effect against glutamate-induced apoptosis through the vital function like Bcl-2/Bax, active caspase-3, p-Akt, p-CREB, and mature BDNF for potent neuroprotective effects of emodin to subsequently enhance behavioral function in cerebral ischemia (Ahn et al., 2016). A different study by Leung et al. located emodin had neuroprotective effects against I/R or OGD injury each in vitro and in vivo, which may perhaps be increase Bcl-2 and glutamate transporter-1 (GLT-l) expression but suppress activated-caspase 3 levels by means of activating ERK1/2 pathway (Leung et al., 2020). Polysaccharides are viewed as to possess a wide range of pharmacological effects, such as scavenging cost-free radicals, immune regulation, anti-tumor, anti-oxidation, anti-viral, antiinflammatory, lowering blood sugar, anti-depression, liver protection, and so forth (Jin et al., 2012; Kwok et al., 2019; Fang et al., 2020). Panax notoginseng polysaccharide is really a sort of heteroglycan derived in the medicinal plant Panax notoginseng, which could raise the ratio of Bcl-2/Bax and lower caspase-3 in cerebral ischemic brain tissue (Jia et al., 2014). What’s a lot more, it could improve GSH-Px, SOD activity and IL 10 level, even though downregulate MDA, TNF-, IL-1 level to decrease cerebral infarction size and cell apoptosis to afford neuroprotective effect (Jia et al., 2014; Sy et al., 2015). ULK1 custom synthesis Angelica polysaccharide will be the most important active ingredient of Angelica sinensis (Oliv.) Diels, which could also enhance the activities of SOD, GSH and GSH-PX, and reduce MDA, IL-1, TNF- and NF-B in cerebral ischemia-reperfusion injury rats.
