基于MLCK-p-MLC通路探讨黄芩苷抗高血压及改善血管功能的作用机制

基于MLCK-p-MLC通路探讨黄芩苷抗高血压及改善血管功能的作用机制摘要：高血压是世界范围内心血管疾病的重要诱因。黄芩苷是一种活性成分，具有降低血压和改善血管功能的作用。本文通过基于MLCK/p-MLC通路探讨黄芩苷抗高血压及改善血管功能的作用机制。结果显示黄芩苷可以通过降低MLCK的磷酸化状态，促进p-MLC的降解来抑制平滑肌细胞收缩，减少血管阻力，从而降低血压。此外，黄芩苷还可以增强一氧化氮合酶的活性，促进一氧化氮的合成，进而扩张血管，增加血管内皮细胞的产生和释放。这些结果说明，黄芩苷可以通过多条途径来减轻高血压，改善血管功能。
