Anti-angiogenic effects of Beta-Eudesmol and atractylodin in developing zebrafish embryos
Comp Biochem Physiol C Toxicol Pharmacol 2021 May;243:108980.PMID:33493664DOI:10.1016/j.cbpc.2021.108980.
Angiogenesis is the process of formation of new blood vessels which plays an essential role in the normal physiological development of the organs and systems. Several factors contribute to and regulate this process. Unregulated angiogenesis, however, is harmful and is usually found in tumors and cancerous cells. β-Eudesmol and atractylodin are sesquiterpenoid contents extracted from the rhizome of Atractylodes lancea (AL). Reports suggest potential anti-angiogenic activities of both compounds. In this study, the anti-angiogenic activities of both compounds were investigated using the well-established zebrafish in vivo model. Zebrafish embryos were treated with a series of concentrations (6.3, 12.5, 25, and 50 μM) of β-eudesmol and (6.3, 12.5, and 25 μM) of atractylodin up to 72 h post-fertilization. Assessment of the effects on phenotypic blood vessel development (sub-intestinal vessel intersection count) revealed that both the compounds inhibited vessel development, particularly at higher concentrations. At the genetic levels, only β-eudesmol significantly downregulated the expression of the Vegfaa gene and also its receptor Vegfr2. β-Eudesmol also affected the expression of Vegfaa protein in a concentration-dependent manner. Results indicate that β-eudesmol exerts anti-angiogenic property through inhibition of Vegfaa at both the gene and protein levels. However, atractylodin does not possess this property.
Beta-Eudesmol suppresses tumour growth through inhibition of tumour neovascularisation and tumour cell proliferation
J Asian Nat Prod Res 2008 Jan-Feb;10(1-2):159-67.PMID:18253884DOI:10.1080/10286020701394332.
In the present study, we investigated the potential anti-angiogenic mechanism and anti-tumour activity of Beta-Eudesmol using in vitro and in vivo experimental models. Proliferation of human umbilical vein endothelial cells (HUVEC) stimulated with vascular endothelial growth factor (VEGF, 30 ng/ml) and basic fibroblast growth factor (bFGF, 30 ng/ml) was significantly inhibited by Beta-Eudesmol (50-100 microM). Beta-Eudesmol (100 microM) also blocked the phosphorylation of cAMP response element binding protein (CREB) induced by VEGF (30 ng/ml) in HUVEC. Beta-Eudesmol (10-100 microM) inhibited proliferation of HeLa, SGC-7901, and BEL-7402 tumour cells in a time- and dose-dependent manner. Moreover, Beta-Eudesmol treatment (2.5-5 mg/kg) significantly inhibited growth of H(22) and S(180) mouse tumour in vivo. These results indicated that Beta-Eudesmol inhibited angiogenesis by suppressing CREB activation in growth factor signalling pathway. This is the first study to demonstrate that Beta-Eudesmol is an inhibitor of tumour growth.
Beta-Eudesmol induces neurite outgrowth in rat pheochromocytoma cells accompanied by an activation of mitogen-activated protein kinase
J Pharmacol Exp Ther 2002 Jun;301(3):803-11.PMID:12023507DOI:10.1124/jpet.301.3.803.
Beta-Eudesmol, a sesquiterpenoid isolated from "So-jutsu" (Atractylodis lanceae rhizomas), is known to have various unique effects on the nervous system. We examined in detail the mechanism by which Beta-Eudesmol modified neuronal function using rat pheochromocytoma cells (PC-12). Beta-Eudesmol at concentrations of 100 and 150 microM significantly induced neurite extension in PC-12 cells, which was accompanied, at the highest concentration, by suppression of [(3)H]thymidine incorporation. Beta-Eudesmol at concentrations of 100 and 150 microM also evoked a significant increase in intracellular Ca(2+) concentration ([Ca(2+)](i)) in these cells, as determined by the fura 2 assay. Much of this increase remained even after the extracellular Ca(2+) was chelated by EGTA. The [Ca(2+)](i) increase induced by Beta-Eudesmol was partially inhibited by the phosphoinositide-specific phospholipase C (PI-PLC) inhibitor 1-[6-[[17beta-methoxyestra-1,3,5(10)-trien-17-yl]amino]hexyl]-1H-pyrrole-2,5-dione (U-73122) (2 microM) under extracellular Ca(2+)-free conditions. Furthermore, Beta-Eudesmol, in a concentration-dependent fashion, caused an accumulation of inositol phosphates. Beta-Eudesmol (150 microM) promoted phosphorylation of both mitogen-activated protein kinase (MAPK) and cAMP-responsive element binding protein in a time-dependent manner. These phosphorylations were suppressed by the MAPK kinase inhibitor 2-(2'-amino-3'-methoxyphenol)-oxanaphthalen-4-one (PD98059) (50 microM), U-73122 (2 microM), the calmodulin inhibitor N-(6-aminohexyl)-5-chloro-1-naphthalenesulfonamide hydrochloride (W7) (1-10 microM), and the protein kinase A inhibitor N-[2-(4-bromocinnamylamino)ethyl]-5-isoquinoline (H89) (1-10 microM). Beta-eudesmol-induced neurite extension was significantly inhibited by both U-73122 (2 microM) and PD98059 (30 microM), suggesting the involvement of PI-PLC and MAPK in neurite outgrowth. Beta-Eudesmol, being a small molecule, may therefore be a promising lead compound for potentiating neuronal function. Furthermore, the drug may be useful in helping to clarify the mechanisms underlying neuronal differentiation.
Antiangiogenic activity of Beta-Eudesmol in vitro and in vivo
Eur J Pharmacol 2005 Apr 11;512(2-3):105-15.PMID:15840394DOI:10.1016/j.ejphar.2005.02.035.
Abnormal angiogenesis is implicated in various diseases including cancer and diabetic retinopathy. In this study, we examined the effect of Beta-Eudesmol, a sesquiterpenoid alcohol isolated from Atractylodes lancea rhizome, on angiogenesis in vitro and in vivo. Proliferation of porcine brain microvascular endothelial cells and human umbilical vein endothelial cells (HUVEC) was inhibited by Beta-Eudesmol (50-100 microM). It also inhibited the HUVEC migration stimulated by basic fibroblast growth factor (bFGF) and the tube formation by HUVEC in Matrigel. Beta-Eudesmol (100 microM) blocked the phosphorylation of extracellular signal-regulated kinase (ERK) 1/2 induced by bFGF or vascular endothelial growth factor. Furthermore, Beta-Eudesmol significantly inhibited angiogenesis in subcutaneously implanted Matrigel plugs in mice and in adjuvant-induced granuloma in mice. These results indicate that Beta-Eudesmol inhibits angiogenesis, at least in part, through the blockade of the ERK signaling pathway. We considered that Beta-Eudesmol may aid the development of drugs to treat angiogenic diseases.
Mechanism of the blocking action of Beta-Eudesmol on the nicotinic acetylcholine receptor channel in mouse skeletal muscles
Neuropharmacology 1991 Aug;30(8):835-41.PMID:1780041DOI:10.1016/0028-3908(91)90117-t.
Beta-Eudesmol, an uncharged alcohol contained in Atractylodes lancea, blocks the neuromuscular junction. Atractylodes lancea is prescribed in a traditional Chinese medicine and plays a main role for "alleviation of pain in skeletal muscle". By using the cell-attached patch-clamp or conventional intracellular technique, the site of action of Beta-Eudesmol on the nicotinic acetylcholine (ACh) receptor (nAChR) channel in skeletal muscle of the adult mouse, was investigated and compared with that of different types of blockers of the nicotinic ACh receptor channel (bupivacaine, chlorpromazine and phencyclidine). Beta-Eudesmol (200 microM) depressed completely the nerve-evoked twitch tension and reduced the amplitude and quantal size of endplate potentials but did not alter either the quantal content, resting membrane potential or action potential. Beta-Eudesmol (100-200 microM) decreased the amplitude of ACh potentials and accelerated the slow decay of depolarization, induced by the continuous application of ACh. Beta-Eudesmol (40 microM) and phencyclidine (10 microM) decreased both the open time and opening frequency, without affecting the single channel conductance. Bupivacaine (10 microM) decreased only the open time. Chlorpromazine (10 microM) decreased only the opening frequency. These results indicate that the blocking effect of Beta-Eudesmol on nerve-evoked contraction, was due to blockade of nicotinic ACh receptor channels at the neuromuscular junction. Like phencyclidine, Beta-Eudesmol blocked the nicotinic ACh receptor channel in both the open and closed conformations, and accelerated the desensitization of the nicotinic ACh receptor.
