Ouabain Octahydrate
CAS No. : 11018-89-6
MCE 国际站：Ouabain Octahydrate
产品活性：Ouabain Octahydrate 是 Na+/K+-ATPase 抑制剂，有潜力用于充血性心力衰竭的研究。
研究领域：Membrane Transporter/Ion Channel | Autophagy
作用靶点：Na+/K+ ATPase | Autophagy
In Vitro: Ouabain (100 μM) induces NLRP3 inflammasome activation and IL-1β release in macrophages. Ouabain-induced NLRP3 inflammasome activation is mediated through K+ efflux. Ouabain (3 nM) alters the expression of EMT markers in NHK and ADPKD cells, and modifies cell-cell adhesion properties in ADPKD. Moreover, ouabain enhances migration of ADPKD cells, selectively modulates tight junctions, and modulates adherens junctions in ADPKD cells in a selective manner. Ouabain also activates TGFβ-Smad3 signaling, alters TER in ADPKD cells. Ouabain (25, 50 or 100 nM) treatment significantly reduces cell proliferation and viability in Raji cells in a dose-dependent manner, with IC50 of 76.48±4.03 nM. Ouabain increases the number of apoptotic cells, induces autophagy, and upregulates Beclin-1 in Raji cells.
In Vivo: Ouabain (3 mg/kg) significantly decreases cardiac contractile force with an enlarged LVESD when mice are primed with LPS. IL-1β deficiency attenuates ouabain-induced cardiac dysfunction and injury. IL-1β secreted by infiltrated macrophages contributes to ouabain-induced cardiac inflammation. Deficiency of NLRP3 and Casp1 attenuates ouabain-induced cardiac dysfunction and macrophage infiltration. Ouabain (30 µg/kg, i.p.) modulates ABCB1 activity in thymocytes of Wistar rats and it has the same effect on Swiss mice at 300 µg/kg. After 14 days of ouabain treatment, the MAP of rats is significantly elevated.

文献和实验一种甾类糖苷，别名 g-毒毛旋花苷。用作强心剂。在原产地也用于制作毒箭。从产于非洲的夹竹桃科的羊角拗属（ St-rophanthus gratus）的种子或同科的 Ac-ocanthera ouabaio的木材中获得。与从毒毛旋花（ S． kom-be）得到的 k-毒毛旋花苷有所区别。可用于研究钠 -钾 ATP酶的特异性抑制剂（ k-毒毛旋花苷也有效）。其强心作用也是基于此种抑制作用，但详细的分子结构不明。其糖苷配基也称乌本苷配基或 g-毒毛旋花苷配基。
Ouabain Modulates Cell Contacts as well as Functions that Depend on Cell Adhesion
Ouabain, a toxic of vegetal origin used for centuries to treat heart failure, has recently been demonstrated to have an endogenous counterpart, most probably ouabain itself, which behaves as a hormone. Therefore, the challenge
