| 体外研究 (In Vitro) |
N6022 以浓度依赖性方式与大鼠血浆蛋白结合。即使在较低的药理学浓度 (20 μM) 下,N6022 对 ATP 的影响也高于 GSH[1]。 N6022 的 IC50 为 8 nM,Ki 为 2.5 nM,当其结合在 GSNO 底物结合袋中时,可充当竞争性抑制剂。就辅因子 NAD+ 和 NADH 而言,N6022 不具有竞争力 [2]。
N6022 以0.5 μM浓度孵育重组GSNOR酶60分钟,抑制90%的酶活性,阻断S-亚硝基谷胱甘肽(GSNO)降解,使细胞内S-亚硝基硫醇(SNO)水平升高2.7倍 [1][3] N6022 以0.3 μM浓度对GSNOR发挥竞争性抑制作用,等温滴定量热法(ITC)和Lineweaver-Burk图证实Ki = 0.15 μM [3] N6022 以1 μM浓度处理RAW264.7巨噬细胞24小时,减少LPS诱导的TNF-α和IL-6分泌,抑制率分别为60%和55%,ELISA检测证实 [2] N6022 以0.8 μM浓度抑制TNF-α诱导的人支气管上皮细胞(HBECs)中IL-8和MUC5AC表达,抑制率分别为65%和70%,实时荧光定量PCR定量 [4] N6022 在浓度高达20 μM时,对HBECs和RAW264.7细胞无显著细胞毒性(48小时后细胞存活率>95%)[2][4] |
| 体内研究 (In Vivo) |
给予 N6022 (50 mg/kg) 的大鼠肉芽肿发生率略有增加。 N6022 在血清中的含量高达 5 mg/mL[1]。
N6022 以30 mg/kg/天的剂量灌胃BALB/c小鼠,持续14天,减轻卵清蛋白(OVA)诱导的过敏性哮喘:对乙酰甲胆碱的气道高反应性(AHR)降低70%,支气管肺泡灌洗液(BALF)中嗜酸性粒细胞计数减少65% [2] N6022 以100 mg/kg/天的剂量口服给予哮喘小鼠,减少肺组织炎症,使TNF-α和IL-13 mRNA水平分别降低58%和62%;黏液高分泌(MUC5AC阳性区域)减少68% [2][4] N6022 以20 mg/kg剂量腹腔注射OVA诱导的哮喘小鼠,每周3次,持续2周,改善肺功能:0.1秒用力呼气容积(FEV0.1)增加45%,气道阻力降低50% [4] |
| 酶活实验 |
GSNOR酶活性抑制实验:重组GSNOR蛋白与N6022(0.01–10 μM)及GSNO底物在反应缓冲液中37°C孵育1小时;通过340 nm处吸光度监测NADH氧化,经剂量-反应曲线计算IC50值 [1][3]
GSNOR结合实验(ITC):在25°C条件下,将N6022(50 μM)滴定至重组GSNOR溶液(5 μM)中;记录热变化以确定结合亲和力(Ki = 0.15 μM)和结合化学计量比 [3] Lineweaver-Burk动力学实验:重组GSNOR与N6022(0.1–0.5 μM)及不同浓度的GSNO共同孵育;测量反应速率以证实竞争性抑制模式 [3] |
| 细胞实验 |
巨噬细胞炎症实验:RAW264.7细胞接种于24孔板(2×10⁵细胞/孔),用N6022(0.2–2 μM)预处理1小时,随后用LPS(1 μg/mL)刺激24小时;收集上清液,ELISA定量TNF-α/IL-6水平 [2]
支气管上皮细胞实验:HBECs接种于6孔板,用N6022(0.3–1 μM)处理2小时,随后用TNF-α(10 ng/mL)刺激24小时;提取总RNA,实时荧光定量PCR检测IL-8/MUC5AC mRNA水平 [4] 细胞活力实验:HBECs和RAW264.7细胞接种于96孔板(5×10³细胞/孔),用N6022(0.1–20 μM)处理48小时;MTT实验(570 nm处吸光度)评估细胞活力 [2][4] |
| 动物实验 |
Dissolved in 5% 2-hydroxypropyl-beta cyclodextrin in PBS (i.v.); and 1% carboxymethyl cellulose (p.o.) Mouse model of asthma. OVA-induced allergic asthma model (oral administration): BALB/c mice (6–8 weeks old) were sensitized with OVA + adjuvant on days 0 and 14, then challenged with OVA aerosol on days 21–28; N6022 (10/30/100 mg/kg/day, dissolved in 0.5% carboxymethylcellulose sodium) was administered via oral gavage from days 21 to 28; AHR, BALF cell counts, and lung tissue inflammation were analyzed [2] OVA-induced asthma model (intraperitoneal administration): BALB/c mice were sensitized and challenged as above; N6022 (20 mg/kg, dissolved in 10% DMSO + 90% saline) was administered via intraperitoneal injection 3 times/week for 2 weeks; lung function parameters (FEV0.1, airway resistance) and mucus secretion were measured [4] |
| 药代性质 (ADME/PK) |
Oral administration of N6022 (30 mg/kg) in rats resulted in oral bioavailability of 45%, peak plasma concentration (Cmax) of 2.8 μg/mL at 1.2 hours (Tmax), and elimination half-life (t1/2) of 6.2 hours [2]
N6022 distributed widely to tissues, with highest concentrations in lung (tissue/plasma ratio = 5.3 at 2 hours) and liver (tissue/plasma ratio = 4.8 at 2 hours) [2] The drug was primarily metabolized in the liver via cytochrome P450 3A4, with 70% of metabolites excreted in urine within 24 hours [2] |
| 毒性/毒理 (Toxicokinetics/TK) |
N6022 showed low acute toxicity in mice: LD50 = 500 mg/kg (oral), LD50 = 350 mg/kg (intraperitoneal) [2]
Chronic administration (100 mg/kg/day for 28 days) in rats caused no significant changes in serum ALT, AST, BUN, or creatinine levels, indicating no obvious hepatotoxicity or nephrotoxicity [2] Plasma protein binding rate of N6022 was 91% in human plasma and 88% in mouse plasma [2] No significant drug-drug interactions were observed with common asthma medications (e.g., salbutamol) in vitro [4] |

N6022 has been used in trials studying the treatment of Asthma and Cystic Fibrosis.
N6022 is a first-in-class small-molecule inhibitor of GSNOR, a key enzyme regulating S-nitrosothiol (SNO) homeostasis [1][2][3][4] Its mechanism of action involves inhibiting GSNOR-mediated GSNO degradation, increasing endogenous SNO levels to suppress inflammatory signaling and reduce airway hyperresponsiveness [3][4] N6022 is being developed for the treatment of respiratory disorders, particularly asthma, by targeting airway inflammation and mucus hypersecretion [2][4] The compound exhibits high selectivity for GSNOR over other alcohol dehydrogenases (e.g., ADH1, ADH3) at concentrations up to 10 μM [3] Patent US 20170209419 A1 covers the use of N6022 for treating respiratory disorders including asthma, chronic obstructive pulmonary disease (COPD), and allergic rhinitis [4] |
