生物活性

产品描述	一种有效的，选择性的 endothelin A receptor 拮抗剂。
靶点	Endothelin Receptor
体外研究	Sitaxsentan and Bosentan attenuate NTCP transport at higher concentrations,and inhibit human hepatic transporters,which provides a potential mechanism for the increased hepatotoxicity observed for these agents in the clinical setting.Only sitaxsentan decreased OATP transport (52%).Sitaxsentan and sitaxsentan combined with sildenafil completely prevent the increased expressions of endothelin-1 and of the ETB receptor.Sitaxsentan alone partially restores the expressions of BMPR-1A and BMPR-2.The combination of sildenafil and sitaxsentan further restores the expressions of BMPR-1A and BMPR2,which remaines, however, decreased compared with controls.
体内研究	Sitaxsentan (5mg/kg infused iv 10 min prior to onset of hypoxia) completely blocks hypoxia-induced vasoconstriction and this group does not differ from air controls.Oral administration of sitaxsentan,significantly attenuates the increase in MPAP,while the administration of sitaxsentan to rats exposed to normal oxygen levels is without effect on MPAP.Sitaxsentan alone limits shunt-induced increase in MT.Sitaxsentan combined with sildenafil more effectively prevents this remodeling,which,however,tends to remain increased compared with controls.

推荐实验方法(仅供参考)

动物实验:
After an initial 2-week period of hypoxic exposure (10% O2) sitaxsentan (15 or 30mg/kg body weight per day in the drinking water) is administered for 4 weeks during continuous exposure to hypoxia.At the conclusion of the 4 week period of hypoxia,femoral and pulmonary arterial cannulation and measurement of MPAP, MSAP,and HR are performed.

本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系，公式为：
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)

用本工具协助配置特定浓度的溶液，使用的计算公式为：
开始浓度 x 开始体积 = 最终浓度 x 最终体积

稀释公式一般简略地表示为：C1V1 = C2V2 ( 输入输出 )
