Ion, and played a S1PR2 site neuroprotective part by way of mitochondrial pathway, antioxidant, anti-inflammatory and anti-apoptotic effects (Costa et al., 2018; Song et al., 2018), which mostly 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). In addition, astragaloside IV could also inhibit neutrophil adhesion related molecules (TNF-a, NF B, IL-1, and so on.) to play an anti-inflammatory part, 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 Organic ProductsBMECs by tetramethylpyrazine phosphate and borneol combination involved 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 Part OF OTHER COMPOUNDS IN ISCHEMIC BRAIN INJURY EmodinEmodin (Figure 5F), 1,three,8-trihydroxy-6-methylanthraquinone, is actually a naturally occurring anthraquinone derivative and an active element from Polygonum multiflorum Thunb. Rheum palmatum L. and so on, which happen to be utilised widely in Asia in treatment of numerous ailments (Dong, X. et al., 2016). Emodin has been demonstrated to possess a wide spectrum of pharmacological effects, such as anti-viral, anti-bacterial, antiallergic, anti-osteoporotic, immunosuppressive, neuroprotective activities (Dong, W. et al., 2016; Leung et al., 2020; Xue et al., 2020). In fact, the neuroprotective effect of Polygonum multiflorum Thunb was very first published in 2000 (Gu et al., 2000) as well as the neuroprotective effect of emodin was published in 2005 when its potential to interfere with the release of glutamate was identified as a method of neuroprotection (Gu et al., 2005). Also, emodin may well afford a substantial neuroprotective impact against glutamate-induced apoptosis via the vital part like Bcl-2/Bax, active caspase-3, p-Akt, p-CREB, and mature BDNF for potent neuroprotective effects of emodin to subsequently improve behavioral function in cerebral ischemia (Ahn et al., 2016). One more study by Leung et al. discovered emodin had neuroprotective effects against I/R or OGD injury both in vitro and in vivo, which may possibly 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 regarded as to possess a wide range of pharmacological effects, including scavenging no cost radicals, immune regulation, anti-tumor, anti-oxidation, anti-viral, antiinflammatory, lowering blood sugar, anti-depression, liver protection, and so on (Jin et al., 2012; Kwok et al., 2019; Fang et al., 2020). Panax notoginseng polysaccharide can be a type of heteroglycan derived in the medicinal plant Panax notoginseng, which could enhance the ratio of Bcl-2/Bax and decrease caspase-3 in cerebral ischemic brain tissue (Jia et al., 2014). What is more, it could boost GSH-Px, SOD activity and IL ten level, while downregulate MDA, TNF-, IL-1 level to minimize cerebral infarction size and cell apoptosis to afford neuroprotective impact (Jia et al., 2014; Sy et al., 2015). Angelica polysaccharide is the most TLR6 supplier important active ingredient of Angelica sinensis (Oliv.) Diels, which could also enhance the activities of SOD, GSH and GSH-PX, and minimize MDA, IL-1, TNF- and NF-B in cerebral ischemia-reperfusion injury rats.
