生物活性

TLC-2716 is an orally available, gut- and liver-restricted inhibitor against LXRα and LXRβ, with EC50 values of 7 nM and 15 nM, respectively. TLC-2716 represses LXRα/β transcriptional activity, downregulates genes involved in lipogenesis, lipid absorption and lipoprotein metabolism, and preserves peripheral reverse cholesterol transport. TLC-2716 reduces lipid accumulation, suppresses inflammation and fibrotic gene expression, enhances triglyceride-rich lipoprotein clearance, and improves glucose homeostasis and insulin sensitivity. TLC-2716 lowers serum and hepatic triglycerides, plasma cholesterol and other atherogenic lipid profiles in experimental models and humanized liver mice. TLC-2716 can be used for the research of dyslipidemia and related cardiometabolic disorders[1].

体外研究
(In Vitro)

TLC-2716 (4 °C 下处理 1 h) 在生化结合实验中可结合重组人源 LXRα (EC50 = 7 nM) 和 LXRβ (EC50 = 15 nM)[1]
TLC-2716 (16 h) 可在 HEK293 哺乳动物双杂交实验中诱导 NCOR 招募至 LXRα 和 LXRβ,对应的 EC50 值分别为 8 nM 和 11 nM;并可分别在 HT‑29 和 HepG2 细胞中抑制 ABCA1 和 SREBP1c 报告基因活性,对应的 IC50 值分别为 15 nM 和 7 nM[1]
TLC-2716 (连续 5 天) 可呈剂量依赖性降低原代人 Upcyte 肝细胞内的甘油三酯蓄积,其 EC50 为 289 nM[1]
TLC-2716 (500 nM-5 μM; 3 days) 可在脂肪变性人肝脏类器官中剂量依赖性地降低细胞内脂质含量,并抑制 LXR 相关基因、脂质代谢相关基因、炎症相关基因及纤维化相关基因的表达,且在 GCKRTT 类器官中的作用效果更强[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
