Antithrombotic activities of aspalathin and nothofagin via inhibiting platelet aggregation and FIIa/FXa.[Pubmed:25325928]
Arch Pharm Res. 2015 Jun;38(6):1080-9.
Aspalathin (Asp) and Nothofagin (Not) are two major active dihydrochalcones found in green rooibos tea (Aspalathus linearis; family, Fabaceae; tribe, Crotalarieae), which have been reported for their anti-oxidant activity. Here, the anticoagulant activities of Asp and Not were examined by monitoring activated partial thromboplastin time (aPTT), prothrombin time (PT), and the activities of thrombin (Factor IIa, FIIa) and activated factor X (FXa). And, the effects of Asp and Not on expression of plasminogen activator inhibitor type 1 (PAI-1) and tissue-type plasminogen activator (t-PA) were evaluated in tumor necrosis factor (TNF)-alpha activated human umbilical vein endothelial cells (HUVECs). Treatment with Asp and Not resulted in prolonged aPTT and PT and inhibition of the activities of thrombin and FXa, as well as inhibited production of thrombin and FXa in HUVECs. In addition, Asp and Not inhibited thrombin-catalyzed fibrin polymerization and platelet aggregation. Asp and Not also elicited anticoagulant effects in mice. In addition, treatment with Asp and Not resulted in significant reduction of the PAI-1 to t-PA ratio. Collectively, Asp and Not possesses antithrombotic activities and offers a basis for development of a novel anticoagulant.
Aspalathin and nothofagin from rooibos (Aspalathus linearis) inhibit endothelial protein C receptor shedding in vitro and in vivo.[Pubmed:25510322]
Fitoterapia. 2015 Jan;100:179-86.
Aspalathin (Asp) and Nothofagin (Not) are two major active dihydrochalcones found in green rooibos, which have been reported for their anti-oxidant activity. Increasing evidence has demonstrated that beyond its role in the activation of protein C, endothelial cell protein C receptor (EPCR) is also involved in vascular inflammation. EPCR activity is markedly changed by ectodomain cleavage and its release as the soluble EPCR. EPCR can be shed from the cell surface, which is mediated by tumor necrosis factor-alpha converting enzyme (TACE). However, little is known about the effects of Asp and Not on EPCR shedding. Our results demonstrated that Asp and Not induced potent inhibition of phorbol-12-myristate 13-acetate (PMA)-, tumor necrosis factor (TNF)-alpha-, interleukin (IL)-1beta, and cecal ligation and puncture (CLP)-induced EPCR shedding. Asp and Not also inhibited the expression and activity of PMA-induced TACE in endothelial cells. Asp and Not also suppressed CLP-induced protein C decrease in mice and thrombin generation in HUVECs. In addition, treatment with Asp and Not resulted in reduced PMA-stimulated phosphorylation of p38, extracellular regulated kinase (ERK) 1/2, and c-Jun N-terminal kinase (JNK). These results demonstrate the potential of Asp and Not as an anti-sEPCR shedding reagent against PMA and CLP-mediated EPCR shedding.
Aspalathin and Nothofagin from Rooibos (Aspalathus linearis) inhibits high glucose-induced inflammation in vitro and in vivo.[Pubmed:25338943]
Inflammation. 2015 Feb;38(1):445-55.
Vascular inflammation plays a key role in the initiation and progression of atherosclerosis, a major complication of diabetes mellitus. Aspalathin (Asp) and Nothofagin (Not) are two major active dihydrochalcones found in green rooibos, which have been reported for their antioxidant activity. In this study, we assessed whether Asp or Not can suppress vascular inflammation induced by high glucose (HG) in human umbilical vein endothelial cells (HUVECs) and mice. We monitored the effects of Asp or Not on HG-induced vascular hyperpermeability, expression of cell adhesion molecules (CAMs), formation of reactive oxygen species (ROS), and activation of nuclear factor (NF)-kappaB in vitro and in vivo. Our data indicate that HG markedly increased vascular permeability, monocyte adhesion, expression of CAMs, formation of ROS, and activation of NF-kappaB. Remarkably, treatment of Asp or Not inhibited HG-mediated vascular hyperpermeability, adhesion of monocytes toward HUVECs, and expression of CAMs. In addition, Asp or Not suppressed the formation of ROS and the activation of NF-kappaB. Since vascular inflammation induced by HG is critical in the development of diabetic complications, our results suggest that Asp or Not may have significant benefits in the treatment of diabetic complications.
Anti-inflammatory Effects of Aspalathin and Nothofagin from Rooibos (Aspalathus linearis) In Vitro and In Vivo.[Pubmed:25655391]
Inflammation. 2015 Aug;38(4):1502-16.
Aspalathin (Asp) and Nothofagin (Not) are two major active dihydrochalcones found in green rooibos, which have been reported for their anti-oxidant activity. Here, we investigated the anti-inflammatory effects and underlying mechanisms of Asp and Not against lipopolysaccharide (LPS)-mediated vascular inflammatory responses. The anti-inflammatory activities of Asp and Not were determined by measuring permeability, monocytes adhesion and migration, and activation of pro-inflammatory proteins in LPS-activated human umbilical vein endothelial cells (HUVECs) and mice. We found that each compound inhibited LPS-induced barrier disruption, expression of cell adhesion molecules (CAMs), and adhesion/transendothelial migration of neutrophils to human endothelial cells. Asp and Not also suppressed LPS-induced hyperpermeability and leukocyte migration in vivo. Furthermore, each compound suppressed the production of tumor necrosis factor-alpha (TNF-alpha) or interleukin (IL)-6 and the activation of nuclear factor-kappaB (NF-kappaB) or extracellular regulated kinases (ERK) 1/2 by LPS. Moreover, treatment with each compound resulted in reduced LPS-induced lethal endotoxemia. These results suggest that Asp and Not posses anti-inflammatory functions by inhibiting hyperpermeability, expression of CAMs, and adhesion and migration of leukocytes, thereby endorsing its usefulness as a therapy for vascular inflammatory diseases.
