GSK4112 (SR6452) 是一种 Rev-erbα 激动剂，EC50 为 0.4 μM。它也是一种用于核血红素受体 Rev-erbα 的细胞生物学的小分子化学探针。

HPG1860, 作为法尼酮X受体(FXR)的激动剂，在使用表达人类FXR的HEK293T细胞的报告基因检测中能引发发光（EC50 = 18 nM）。动物体内实验显示，HPG1860（每天1、3、或10 mg kg）可以减少非酒精性脂肪性肝炎（NASH）小鼠模型的血清谷丙转氨酶（ALT）和总胆固醇水平，该小鼠模型是通过高脂饮食和四氯化碳（CCl4）诱导的。此化合物还能降低肝部的炎症、脂肪积累及纤维化。

4-Epidoxycycline 是抗生素 doxycycline 的肝脏代谢产物，在小鼠中不具备抗生素功能。4-Epidoxycycline 在体外实验和活体小鼠模型中调节 HER2 基因表达的效果与 doxycycline 相近，并在肿瘤组织中展现出与 doxycycline 类似的高效性，肿瘤消退率超过 95%。

Anti-NASH agent 2 (compound 21) 是一种能够抑制新生脂肪生成和 α-SMA 基因表达的药物。Anti-NASH agent 2 可有效改善 NASH 小鼠模型中的肝脂肪变性、水肿、炎症浸润及肝纤维化。

Givinostat (ITF-2357) is a HDAC inhibitor with an IC50 of 198 and 157 nM for HDAC1 and HDAC3, respectively. Givinostat (ITF2357) suppresses total LPS-induced IL-1β production robustly compared with the reduction by ITF3056. At 25, 50, and 100 nM, Givinostat reduced IL-1β secretion more than 70%. Givinostat (ITF-2357) suppresses the production of IL-6 in PBMCs stimulated with TLR agonists as well as the combination of IL-12 plus IL-18. IL-6 secretion decreases to 50% at 50 nM Givinostat, but at 100 and 200 nM, there is no reduction[1]. As shown by the CCK-8 assay, Givinostat (ITF-2357) inhibits JS-1 cell proliferation in a concentration-dependent manner. Treatment with Givinostat ≥500 nM is associated with significant inhibition of JS-1 cell proliferation (P<0.01). Also, the cell inhibition rate significantly differs between the group cotreated with Givinostat ≥250 nM plus LPS and the group without LPS treatment (same Givinostat concentration) (P<0.05)[2]. Givinostat (ITF2357) at 10 mg kg is used as a positive control and, as expected, reduced serum TNFα by 60%. Strikingly, pretreatment of ITF3056 starting at 0.1 mg kg significantly reduces the circulating TNFα by nearly 90%. To achieve a significant increase in serum IL-1β production, a higher dose of LPS is injected (10 mg kg), and blood is collected after 4 h. Similarly, when pretreated with lower doses of Givinostat (ITF-2357) (1 or 5 mg kg), there is a 22% reduction for 1 mg kg and 40% for 5 mg kg[1]. [1]. Li S, et al.

SBI993 是 SBI-477 的类似物，可用作生物标志物来确认 MondoA 靶基因在体内表达的预期作用。 SBI993 降低肌肉 TAG 水平和肝脂肪变性。

3,7-DMF作为一种口服活性抑制剂，有效抑制了TGF-β1诱导的HSC活化，并通过诱导抗氧化基因及淬灭ROS为研究肝纤维化提供了潜在应用。
