N-Acetyl-L-cysteine ethyl ester (NACET) 是氨基酸-l-半胱氨酸的衍生物。N-Acetyl-L-cysteine ethyl ester 已被证明具有广泛的生化和生理作用，包括抑制蛋白质合成、抑制DNA 复制和诱导细胞凋亡。它还被证明具有抗炎、抗氧化和抗癌活性

RORγt agonist 3 是 RORγt 的有效激动剂。RORγt agonist 3 能够促使 Th17 细胞分化，增加促炎细胞因子水平，进而提高淋巴细胞的细胞毒性。RORγt agonist 3 能够阻碍调节性 T 细胞的产生，并免疫反应产生抑制作用。

7β,27-dihydroxy Cholesterol is an oxysterol and agonist of retinoic acid receptor-related orphan receptor γ (RORγ) and RORγt. [1] It activates RORγ- or RORγt-dependent signaling with EC50 values of 691 and 1,045 nM, respectively, in reporter assays using HEK293T cells expressing the recombinant human receptors. 7β,27-dihydroxy Cholesterol is selective for RORγ and RORγt over a panel of eight additional nuclear receptors at 30 µM. It increases IL-17A production in Th17-polarized isolated human na ve CD4+ T cells when used at a concentration of 300 nM. 7β,27-dihydroxy Cholesterol (60 mg/kg) increases IL-17A production in isolated mouse γδ T cells stimulated with 12-myristate 13-acetate and ionomycin .

ARN19874 is a selective, reversible uncompetitive N-acylphosphatidylethanolamine phospholipase D (NAPE-PLD) activity inhibitor. With an IC50 of ~34 μM[1].
