The Effect of Isosaponarin Derived from Wasabi Leaves on Glutamate Release in Rat Synaptosomes and Its Underlying Mechanism
Int J Mol Sci 2022 Aug 6;23(15):8752.PMID:35955884DOI:10.3390/ijms23158752.
Excessive glutamate release is known to be involved in the pathogenesis of neurological diseases, and suppression of glutamate release from nerve terminals is considered to be a treatment strategy. In this study, we investigated whether Isosaponarin, a flavone glycoside isolated from wasabi leaves, could affect glutamate release in rat cerebral cortex nerve terminals (synaptosomes). The release of glutamate was evoked by the K+ channel blocker 4-aminopyridine (4-AP) and measured by an online enzyme-coupled fluorimetric assay. Isosaponarin produced a concentration-dependent inhibition of 4-AP-evoked glutamate release with a half-maximum inhibition of release value of 22 μM. The inhibition caused by Isosaponarin was prevented by eliminating extracellular Ca2+ or by using bafilomycin A1, an inhibitor of synaptic vesicle exocytosis. Isosaponarin decreased intrasynaptosomal rises in Ca2+ levels that were induced by 4-AP, without affecting the synaptosomal membrane potential. The isosaponarin-induced inhibition of glutamate release was significantly prevented in synaptosomes that were pretreated with a combination of the calcium channel blockers ω-conotoxin GVIA (N-type) and ω-agatoxin IVA (P/Q-types). The protein kinase C (PKC) pan-inhibitor GF109203X and the Ca2+-dependent PKC inhibitor Go6976 abolished the inhibition of glutamate release by Isosaponarin, while the Ca2+-independent PKC inhibitor rottlerin did not show any effect. The results from immunoblotting assays also showed that Isosaponarin lowered PKC, PKCα, synaptosomal-associated protein of 25 kDa (SNAP-25), and myristoylated alanine-rich C-kinase substrate (MARCKS) phosphorylation induced by 4-AP. In addition, FM1-43-labeled synaptic vesicles in synaptosomes showed that treatment with Isosaponarin resulted in an attenuation of the 4-AP-induced decrease in fluorescence intensity that is consistent with glutamate release. Transmission electron microscopy of synaptosomes also provided evidence that Isosaponarin altered the number of synaptic vesicles. These results indicate that Isosaponarin suppresses the Ca2+-dependent PKC/SNAP-25 and MARCKS pathways in synaptosomes, causing a decrease in the number of available synaptic vesicles, which inhibits vesicular glutamate release from synaptosomes.
The effect of Isosaponarin isolated from wasabi leaf on collagen synthesis in human fibroblasts and its underlying mechanism
J Nat Med 2010 Jul;64(3):305-12.PMID:20349148DOI:10.1007/s11418-010-0412-y.
Wasabi has been used as an important spice in Japanese foods. The wasabi leaves were used as a cosmetic material, but its biological activities have not yet been examined. We investigated the effect of Isosaponarin derived from wasabi leaf on collagen synthesis in human fibroblasts. The production of type I collagen in human fibroblasts was increased with treatment of wasabi leaf extract. Isosaponarin isolated from wasabi leaves belonged to the group of flavone glycoside, and was the key compound in collagen synthesis from the wasabi leaf ingredients. Isosaponarin increased the type I collagen production at the mRNA gene level. The treatment of Isosaponarin did not influence the production of transforming growth factor-beta (TGF-beta) protein, but increased the production of TGF-beta type II receptor (TbetaR-II) protein and TbetaR-II mRNA. Prolyl 4-hydroxylase (P4H) protein and P4H mRNA were increased by treatment with Isosaponarin. Heat shock protein 47 (HSP47) was not increased by treatment with Isosaponarin. These results suggested that Isosaponarin increased collagen synthesis in human fibroblasts, caused by up-regulated TbetaR-II and P4H production.
Identification and Characterization of Apigenin 6-C-Glucosyltransferase Involved in Biosynthesis of Isosaponarin in Wasabi (Eutrema japonicum)
Plant Cell Physiol 2019 Dec 1;60(12):2733-2743.PMID:31418788DOI:10.1093/pcp/pcz164.
Wasabi (Eutrema japonicum) is a perennial plant native to Japan that is used as a spice because it contains isothiocyanates. It also contains an Isosaponarin, 4'-O-glucosyl-6-C-glucosyl apigenin, in its leaves, which has received increasing attention in recent years for its bioactivity, such as its promotion of type-I collagen production. However, its biosynthetic enzymes have not been clarified. In this study, we partially purified a C-glucosyltransferase (CGT) involved in Isosaponarin biosynthesis from wasabi leaves and identified the gene coding for it (WjGT1). The encoded protein was similar to UGT84 enzymes and was named UGT84A57. The recombinant enzyme of WjGT1 expressed in Escherichia coli showed C-glucosylation activity toward the 6-position of flavones such as apigenin and luteolin. The enzyme also showed significant activity toward flavonols, but trace or no activity toward flavone 4'-O-glucosides, suggesting that Isosaponarin biosynthesis in wasabi plants would proceed by 6-C-glucosylation of apigenin, followed by its 4'-O-glucosylation. Interestingly, the enzyme showed no activity against sinapic acid or p-coumaric acid, which are usually the main substrates of UGT84 enzymes. The accumulation of WjGT1 transcripts was observed mainly in the leaves and flowers of wasabi, in which C-glucosylflavones were accumulated. Molecular phylogenetic analysis suggested that WjGT1 acquired C-glycosylation activity independently from other reported CGTs after the differentiation of the family Brassicaceae.

In silico analysis of polyphenols and flavonoids for design of human Nav1.7 inhibitors
J Biomol Struct Dyn 2021 Aug;39(12):4472-4479.PMID:32686994DOI:10.1080/07391102.2020.1777902.
Neuropathic pain is commonly associated with lesion or disease of the somatosensory system and often reflected as indicator of impaired life. Although the central nervous system is main regulator of pain but for initiation and maintenance of the neuropathic pain is regulated by peripheral nervous system. Sodium channels particularly Nav1.7, Nav1.8, Nav 1.9 are key stake holders in the peripheral neuropathy, activation of these sodium channels might lead to genesis and propagation. Flavonoids and polyphenols showed promising effects in neuropathic pain. Here we are reporting In silico analysis of some selected flavonoids and polyphenols on sodium activated voltage channel 1.7 to explore the structural fragments required for binding. Results indicated Baicalin, Butrin, Dihydromonospermoside, Icariin, Isocoreopsin and Isosaponarin are showing promising docking score with sodium activated voltage channel 1.7 than other compounds. Structural modification of these promising leads keeping pharamcophoric requirement intact may yield potent Nav1.7 inhibitors for peripheral pain management.Communicated by Ramaswamy H. Sarma.
