CCG-222740 是一种口服有效的选择性Rho MRTF 途径抑制剂。它也是 α-平滑肌的肌动蛋白表达抑制剂，可减少皮肤纤维化并阻止黑色素瘤转移。

safironil 是一种新型抗纤维化化合物，是胶原蛋白合成的竞争性抑制剂。safironil 在体外实验中对由胶原蛋白I mRNA 或平滑肌α-actin 水平监测的成纤维细胞的激活，以及由I 型和III 型胶原蛋白和层粘连蛋白生产判断的纤维生成有抑制作用。safironil 在不改变总羟脯氨酸的情况下对肝脏肉芽肿的大小没有影响，但通过增加III 型和减少I 型胶原的沉积改变了纤维化的模式。

Prazosin hydrochloride (Vasoflex) 是一种选择性肾上腺素能 α-1 拮抗剂，可降低外周阻力并放松血管平滑肌。 它可用于研究高血压和酒精使用障碍。 它是一种合成哌嗪衍生物，具有降压抗肾上腺素能特性。它抑制有机阳离子转运蛋白 OCT-1 和 OCT-3，IC50分别为 1.8 和 13 μM 。

Phenoxybenzamine hydrochloride (NCI-c01661) 是一种选择性的 α-adrenoceptor 和 calmodulin 的抑制剂，是常用的抗高血压药。

Midodrine hydrochloride (Pro-Amatine) 通过去甘氨酸反应转化为其活性代谢物 desglymidodrine。Desglymidodrine 选择性地结合并激活小动脉和静脉血管系统的 α-1-肾上腺素能受体。这会导致平滑肌收缩并导致血压升高。 Desglymidodrine 在血脑屏障中的扩散很差，因此与对中枢神经系统的影响无关。Midodrine hydrochloride 是 midodrine 的盐酸盐形式，是一种直接作用的前药和拟交感神经药，具有抗低血压特性。

Prim-O-glucosylcimifugin (Cimifugin 7-glucoside) 具有强效的抗炎作用。通过调节 JAK2 STAT3 信号传导可抑制iNOS 和COX-2表达。

Dapiprazole Hydrochloride (Glamidolo Hydrochloride) 是 α-adrenergic 阻断剂的药物。

The growth factors, platelet-derived growth factor (PDGF) and basic fibroblast growth factor (bFGF) play major roles in enhanced smooth muscle cells growth in rodent blood vessels after vascular injury. Tyrosine kinase inhibition has been shown to be effective in blocking tyrosine phosphorylation at the PDGF and bFGF receptors in cultured fibroblast and vascular smooth muscle cells which in turn inhibits their proliferation[1]. CGP 53716 is a specific PDGFR tyrosine kinase inhibitor on SMC (smooth muscle cell) proliferation and migration in vitro and in neointimal formationin vivo[3]. CGP 53716 inhibited serum-induced cell growth in RASMC (rat aortic smooth muscle cells). And it completely blocked PDGF-BB tyrosine receptor autophosphorylation in RASMC and 3T3 cells, PDGF-BB-induced phosphorylation of mitogen-activated protein kinase at 1 μM in RASMC and inhibited PDGF-BB-induced c-Fos protein expression at 1 μM in RASMC; consistent with inhibition of PDGF-BB-induced DNA synthesis. Further, CGP 53716 inhibited PDGF-BB-, bFGF- and EGF-induced DNA synthesis in a concentration-dependent manner in each cell line. And it showed a 2- to 4-fold selectivity for PDGF-BB-stimulated DNA synthesis over bFGF or EGF in RASMC or 3T3 cells[1]. CGP 53716 inhibited dose dependently tyrosine phosphorylation of both the known PDGFRs: the PDGFR-α and PDGFR-β. After rat carotid artery ballooning injuryin vivo, the migration of alpha-actin-positive cells on the luminal side of internal elastic lamina was decreased with 50 mg kg day of CGP 53716 from 38 ± 10 (control group) to 4 ± 2. Intima media ratio was inhibited by 40% after 14 days in the CGP 53716-treated group (P=0.028) after rat aortic denudation[3].

Doxazosin HCl is the salt form of Doxazosin Free Base which acts by inhibiting the postsynaptic alpha(1)-adrenoceptors on vascular smooth muscle. This inhibits the vasoconstrictor effect of circulating and locally released catecholamines (epinephrine and norepinephrine), resulting in peripheral vasodilation.
