acute lung injury

HCH6-1 是甲酰肽受体 1 的竞争性二肽拮抗剂。它能够抑制 fMLF (FPR1激动剂) 特异性激活的人中性粒细胞的趋化性、超氧阴离子生成和弹性酶释放。动物实验中，它对急性肺损伤具有保护作用，可用于研究 FPR1 参与的炎症性肺部疾病。

N-Oleoyl valine is an endogenous N-acyl amine that acts as an antagonist at the transient receptor potential vanilloid type 3 (TRPV3) receptor, which is involved in thermoregulation. N-Oleoyl valine is increased in mice following cold exposure for up to at least 16 days. Acute lung injury in mice increases the concentration of N-Oleoyl valine in lung tissue. N-acyl amines also promote mitochondrial uncoupling.

SN50是一种细胞渗透性的NF-κB的核转位抑制剂，具有NF-κB p50 亚基的核定位序列，能够保护呼吸机诱导的大鼠急性肺损伤并且抑制IL-1β、TNF-α、MPO、MAPKs的表达，还可以诱导小胶质细胞向M2型分化。

Antileukinate is a synthetic hexapeptide with an acetylated amino terminus and an amidated carboxyl terminus that inhibits the binding of CXC chemokines to the chemokine receptor CXCR2. It inhibits IL-8 binding to neutrophils (Ki = 2.7-13 μM), prevents neutrophil chemotaxis and β-glucuronidase release, and blocks IL-8-induced skin edema in rabbits. At 53 mg/kg, antileukinate has been shown to protect mice against acute pancreatitis and associated lung injury.

AMY-101 acetate (Cp40 acetate) 是一种环肽，是补体C3(C3 Complement)的抑制剂和免疫调节剂，用于治疗牙龈炎和牙周炎，能够显著降低炎症并且降低MMP-8和MMP-9水平。AMY-101 acetate还对covid -19诱导的急性呼吸窘迫综合征（ARDS）患者的肺部炎症/损伤和SARS-COV-2相关的急性肾损伤具有缓解作用。

TREM-1 inhibitory peptide M3为一种配体依赖的TREM-1拮抗剂。该化合物能够有效抑制全身及肺部促炎细胞因子与趋化因子的产生，有助于缓解急性肺损伤。

Ac2-26 TFA, an active N-terminal peptide of annexin A1 (AnxA1), attenuates ischemia-reperfusion-induced acute lung injury. Ac2-26 also decreases AnxA1 protein expression, inhibits the activation of NF-κB and MAPK pathways in the injured lung tissue.

Ac2-26是一种Annexin A1的模拟肽，能够通过抑制p38MAPK/NF-κB减轻糖尿病小鼠模型的肾脏炎症损伤，还能够通过LXA4/PI3K/AKT信号通路抑制脓毒症诱导的心肌细胞凋亡，以及通过调节IL-22/IL-22R1/STAT3信号通路减轻小鼠肝缺血再灌注损伤。

Ac2-26 acetate 是一种膜联蛋白 A1(AnxA1) 的活性 N 末端肽。 Ac2-26 acetate 降低 AnxA1 蛋白表达并抑制受损肺组织中 NF-κB 和 MAPK 通路的激活。 Ac2-26 acetate 可减轻缺血再灌注诱导的急性肺损伤。

AMY-101 TFA是一种环肽，是补体C3的抑制剂和免疫调节剂，用于治疗牙龈炎和牙周炎，能够显著降低炎症并且降低MMP-8和MMP-9水平。AMY-101 TFA还对covid -19诱导的ARDS患者的肺部炎症/损伤和SARS-COV-2相关的急性肾损伤具有缓解作用。
