Abstract:
背景和目的: 硫化氢(HS) - 释放剂被视为潜在的降压药。最近,天然异硫氰酸盐作为原始H出现S-Donor代理。其中,存在于一些可食用的十字花科植物中的Erucin显示出合适的HS释放特性和“可药物性”的特征。 The aim of this work was to investigate the erucin-mediated release of HS inside vascular cells, its vasorelaxing effects, and activity on BP of normo and hypertensive animals.
EXPERIMENTAL APPROACH: Intracellular HS-release and the hyperpolarizing effect of erucin were tested using fluorescent dye, in human主动脉平滑肌细胞(HASMC)。它的直接血管长作用和抑制去甲肾上腺素引起的血管收缩的能力在内皮INTACT或串联的大鼠主动脉环上评估。使用langendorff ppered鼠的大鼠心脏在冠状动脉中测试了其血管扩张剂的特性。最后,通过使用尾扣方法记录收缩压,在体内评估了肌蛋白的降压活性。
关键结果: erucin诱导HS在HASMC中的释放。此外,Erucin超极化以浓度依赖性方式使HASMCS膜的膜化。它诱导内皮构成的血管中大鼠主动脉环的血管扩张。内皮号的存在进一步改善了这种效果。当与大鼠主动脉环预孵育时,肌蛋白诱导浓度依赖性抑制去甲肾上腺素诱导的血管收缩。肌肉素不影响基础冠状动脉流,而是在预取冠状血管中恢复了正常的流动。 Finally, in vivo, erucin decreased systolic BP in SHRs by about 25%, and restored the BP to values observed in normotensive rats.
CONCLUSIONS AND IMPLICATIONS: Erucin is an HS donor endowed with vasorelaxing and antihypertensive效果。
