CB2 receptor agonist 9 (Compound 33) 是一种有效的口服大麻素受体 2 (CB2 receptor) 激动剂，EC50 为 16.2 nM。CB2 receptor agonist 9 能抑制 TNF-α、IL-1β 和 IL-6 的表达，并在 DDS 诱导的小鼠急性结肠炎模型中显示抗炎活性。

9(Z),11(E)-Conjugated linoleic acid is an isomer of linoleic acid that has been found in beef and milk fat.1It binds to peroxisome proliferator-activated receptor α (PPARα; IC50= 140 nM) and activates the receptor in a reporter assay using COS-1 cells expressing mouse PPARα when used at a concentration of 100 μM.29(Z),11(E)-Conjugated linoleic acid inhibits TNF-α-inducedGLUT4expression and increases insulin-stimulated glucose transport in 3T3-L1 adipocytes.3Dietary administration of 9(Z)11(E)-conjugated linoleic acid reduces serum fasting glucose, insulin, and triglyceride levels and decreases white adipose tissue macrophage infiltration inob/obmice. It also increases body weight gain and body fat in weanling mice.4[Matreya, LLC.

MMP-9 inhibitor I is an inhibitor of matrix metalloproteinase-9 (MMP-9) that is selective over MMP-1 and MMP-13 (IC50s = 5, 1,050, and 113 nM, respectively). It also decreases the activity of TNF-α converting enzyme (TACE) in a dose-dependent manner (IC50 = 0.54 μM). MMP-9 inhibitor I decreases TNF-α secretion stimulated by LPS in BV-2 microglial cells when used at concentrations of 50 and 100 μM.

GSK-J4 Hydrochloride (GSK J4 HCl) 是 H3K27me3/me2 去甲基化酶 JMJD3/KDM6B 和 UTX/KDM6A 双抑制剂，IC50分别为 8.6 和 6.6 μM。它是 GSK-J1 的乙酯衍生物，体外 IC50 值大于 50 μM。它抑制 LPS 诱导的人原代巨噬细胞产生 TNF-α，IC50值为 9 μM。

UCB-5307 是一种小分子化合物，可在体外抑制 TNFR1 信号转导和下游功能。 人 TNFα 的 KD 为 9 nM。 TNF 直接通过缓慢的结合动力学结合，KD = 6 nM。 UCB-5307 可以通过预制的 hTNF/hTNFR1 复合物。

Glucocorticoid receptor modulator 1是一种高效和可口服的 NF-κB和AP-1抑制剂，IC50分别为9 nM和130 nM，能够下调炎症因子IL-6、IL-1β、TNF-α、MMP-13的表达，缓解皮肤炎症。

3-Hydroxyxanthone (3-Hydroxy-xanthen-9-one) 是一种具有抗炎活性的氧杂蒽酮化合物。它能抑制人脐静脉内皮细胞（HUVEC）中NADPH催化的脂质过氧化，并且阻止TNF-α所诱导的ICAM-1表达。

PON-PC, an oxidized phospholipid with a 9-carbon fatty acyl chain ending in an aldehyde at the sn-2 position, arises from the oxidation of palmitoyl oleoyl phosphatidylcholine (POPC) or through interaction with ozone in pulmonary surfactant. It is found in oxidized LDL. At a 40 µM concentration, PON-PC diminishes the production of TNF-α, nitric oxide (NO), and NADP+ in primary mouse alveolar macrophages and lowers the bactericidal capability of RAW 264.7 cells. Additionally, levels of PON-PC increase in the bronchoalveolar lavage fluid (BALF) of mice exposed to cigarette smoke or in older mice.

TIC10g，作为TLR7和TLR9（Toll样受体7和9）的双重抑制剂，能够在小鼠巨噬细胞（IC50为14.5 μM和6.5 μM）及人类B淋巴细胞（IC50为7.69 μM和11.5 μM）中抑制由TLR7和TLR9介导的TNF-α释放。此外，TIC10g还能抑制NF-κB与MAPK的活化，显示出对系统性红斑狼疮和类风湿性关节炎的抗炎活性。

Pimaric acid 是一种天然树脂酸，可在 Aralia cordata 及多种松属植物中发现。Pimaric acid 通过诱导内质网应激、激活半胱天冬酶依赖性凋亡、细胞周期阻滞及抑制卵巢癌细胞迁移发挥抗癌作用。此外，Pimaric acid 可抑制 TNF-α 刺激的人主动脉平滑肌细胞 (HASMCs) 中基质金属蛋白酶-9 (MMP-9) 的 mRNA 表达、蛋白水平及启动子活性，支持其在癌症及血管研究中的应用价值。
