Using dehydroabietic acid as the lead compound for structural modification, 25 dehydroabietic acid derivatives were synthesized. Among them, compound D1 not only showed the strongest relaxation effect on the aortic vascular ring in vitro (Emax = 99.5 ± 2.1%, EC50 = 3.03 ± 0.96 µM), but also significantly reduced systolic and diastolic blood pressure in rats at a dose of 2.0 mg/kg in vivo. Next, the
以脱氢松香酸为先导化合物进行结构修饰,合成了25种脱氢松香酸衍生物。其中,化合物D1不仅在体外对主动脉血管环表现出最强的舒张作用(Emax=99.5±2.1%,EC 50 =3.03±0.96μM),而且在一定剂量下能显着降低大鼠的收缩压和舒张压。体内浓度为 2.0 mg/kg。接下来,通过HUVECs进一步研究最佳活性D1的血管保护作用及其分子机制。结果表明, D1以浓度依赖性方式诱导大鼠胸主动脉内皮依赖性舒张。使用 NG -硝基-l-精氨酸甲酯 ( l -NAME)、1 H -[1,2,4]-恶二唑并-[4,3-a]-喹喔啉-1-酮 (ODQ) 去除内皮或主动脉环预处理)和四乙铵(TEA)显着抑制D1诱导的松弛。此外,渥曼青霉素、KT5823、曲西立宾、地尔硫卓、BaCl 2 、4-氨基吡啶、吲哚美辛、普萘洛尔和阿托品可减弱D1诱导的血管舒张作用。 D1增加了 HUVEC 中 eNOS
