endothelium dependent relaxation

L-Nabe (H-Arg(NO2)-Obzl) 是一种有效的不可逆内皮依赖性舒张抑制剂。

CGP48369 是一种有效的血管紧张素 II 受体 (angiotensin II receptor) 拮抗剂，具有降血压作用，可增强自发性高血压大鼠冠状动脉的内皮依赖性松弛。

ICI 169369, a 5-HT2/5-HT1C antagonist, can evoke endothelium-dependent relaxation in rabbit aorta.

Nolpitantium Free Base is a highly selective nonpeptide antagonist of neurokinin-1 (NK1) receptor. Nolpitantium potently, selectively and competitively inhibited substance P binding to NK1 receptors from various animal species, including humans. In vitro, it was a potent antagonist in functional assays for NK1 receptors such as [Sar9, Met(O2)11]substance P-induced endothelium-dependent relaxation of rabbit pulmonary artery and contraction of guinea-pig ileum. Up to 1 mkM, Nolpitantium had no effect in bioassays for NK2 and NK3 receptors. The antagonism exerted by Nolpitantium toward NK1 receptors was apparently non-competitive, with pD2' values between 9.65 and 10.16 in the different assays. Nolpitantium also blocked in vitro [Sar9, Met(O2)11]substance P-induced release of acetylcholine from rat striatum. In vivo, Nolpitantium exerted highly potent antagonism toward [Sar9, Met(O2)11]substance P-induced hypotension in dogs, bronchoconstriction in guinea-pig) and plasma extrava......

Quercetin-3-O-(2′′-O-galloyl)-β-D-glucopyranoside 是一种从天竺葵属植物中分离的酚类化合物，具有口服活性和抗炎特性，可能在治疗水肿和改善主动脉内皮依赖性舒张损伤方面有应用潜力。

Adrenomedullin(porcine)是一種多肽，具有调节血管舒张的功能。它在内皮依赖性条件下能诱导大鼠主动脉舒张，IC50为2.4 nM；在内皮非依赖性条件下则能诱导猪冠状动脉舒张，IC50为27.6 nM。

Cimicifugic acid D (2-Caffeoylpiscidic acid) 是一种苄基酒石酸酯，能够诱导预收缩的大鼠主动脉条血管扩张，并启动内皮依赖性舒张机制。在Norepinephrine引起的大鼠主动脉条收缩过程中，Cimicifugic acid D 通过抑制受体操纵的Ca2+通道（ROC）的胞外Ca2+内流发挥作用，而不影响电压依赖性Ca2+通道（VDC）或K+诱导的收缩。

IRL-1038 TFA 是一种具有选择性和高效性的内皮素 B（ETB）受体拮抗剂， 抑制内皮素诱导的内皮依赖性松弛，可用于研究心血管疾病。
