Abstract

Jujuboside B has been reported to have protective effect on many cardiovascular diseases. However, the effects of Jujuboside B on vascular tension and endothelial function are unknown. The present study investigated the effects of Jujuboside B on reducing vascular tension, protecting endothelial function and the potential mechanisms. The tension of isolated rat thoracic aorta ring was measured by Wire myograph system. The concentration of nitric oxide (NO) and the activity of endothelial nitric oxide synthase (eNOS) in human aortic endothelial cells (HAECs) were determined by Griess reagent method and enzyme-linked immune sorbent assay. The protein levels of eNOS and p-eNOS at Serine-1177 were determined by western blot analysis. Intracellular Ca2+ concentration in HAECs was measured by laser confocal imaging microscopy. Results showed that Jujuboside B reduced the tension of rat thoracic aorta rings with intact endothelium in a dose-dependent manner. L-NAME, KN93, EGTA, SKF96365, iberiotoxin and glibenclamide significantly attenuated Jujuboside B-induced vasodilation in endothelium-intact tissues. In contrast, indometacin and 4-DAMP had no such effects. Jujuboside B also promoted NO generation and increased eNOS activity, which were attenuated by L-NAME, EGTA and SKF96365. Moreover, Jujuboside B increased intracellular Ca2+ concentration dose-dependently, which was inhibited by EGTA and SKF96365. Besides, Jujuboside B induced a rapid Ca2+ influx instantaneously after depleting intracellular Ca2+ store, which was significantly inhibited by SKF96365. In conclusion, this study preliminarily confirmed that Jujuboside B reduced vascular tension endothelium-dependently. The underlying mechanisms involved that Jujuboside B increased extracellular Ca2+ influx through endothelial transient receptor potential cation (TRPC) channels, phosphorylated eNOS and promoted NO generation in vascular endothelial cells. In addition, Jujuboside B-induced vasodilation involved endothelium-dependent hyperpolarizaiton through endothelial potassium channels. Jujuboside B is a natural compound with new pharmacological effects on improving endothelial dysfunction and treating vascular diseases.

Abstract

Initiation of necroptosis has been considered as a promising strategy for anticancer therapies, especially for eradicating apoptosis-resistant malignant cells. Jujubisode B is a natural saponins extracted from the seeds of Zizyphi Spinosi Semen, and possesses multiple pharmacological activities, including antianxiety, anti-inflammation, antiplatelet aggregation and induction of apoptosis. This study aims to explore the effect of jujuboside B on acute leukemic cells and the underlying mechanisms. Our results showed that jujuboside B inhibited leukemia cell growth in a dose-dependent manner and attenuated the clonogenic ability of U937 cells, concomitant with activation of RIPK1/RIPK3/MLKL pathway; these phenomena were evidently blocked by necroptosis inhibitor (Nec-1). With the help of Molecular Operating Environment (MOE) program, we identified that RIPK1, RIPK3 and MLKL are potential targets of jujuboside B. To the best of our knowledge, this is the first study to provide evidence that jujuboside B possesses antileukemic activity via a mechanism involving activation of RIPK1/RIPK3/MLKL pathway.

Abstract

Jujuboside B (1) is one of the saponins isolated from the seeds of Zizyphus jujuba var. spinosa, which are used as a well-known traditional medicine for the treatment of insomnia and anxiety in East Asian countries. This is the first study to investigate the antitumor mechanism of 1 in vivo and in vitro. The results showed that 1 induced apoptosis and autophagy in AGS and HCT 116 human cancer cells and also effectively suppressed tumor growth in a nude mouse xenograft model bearing HCT 116 cells. The apoptosis-inducing effect of 1 was characterized by annexin V/propidium iodide staining, sub-G1 phase increase, and caspase-3 activation. Mechanistic studies showed that 1-induced apoptosis is associated with the extrinsic pathway through an increase in FasL and caspase-8 activation. Moreover, 1 activated p38/c-Jun N-terminal kinase (JNK), and the extrinsic pathway-mediated apoptosis was attenuated by both SB202190 (a p38 inhibitor) and SP600125 (a JNK inhibitor). The autophagy-inducing effect was indicated by the formation of cytoplasmic vacuoles and microtubule-associated protein 1 light chain-3 II (LC3-II) conversion. The autophagy inhibitor bafilomycin A1 (BaF) decreased 1-induced cell viability and increased pp38, pJNK, FasL, caspase-8 activation, and caspase-3 activation. Taken together, these results demonstrate that 1 induced protective autophagy to retard extrinsic pathway-mediated apoptosis.
