SGX523 是选择性的和 ATP 竞争性的MET 抑制剂 (IC50:4 nM)。它对 MET 的选择性其它他蛋白激酶高 1000 倍。它具有抗肿瘤特性。

Inecalcitol 是一种独特的维生素 D3 类似物，可诱导细胞凋亡，有抗癌活性。它是一种具有口服活性维生素 D 受体激动剂，Kd 为 0.53 nM。

CRX-526, a TLR4 antagonist, protects against advanced diabetic nephropathy.

NCD38 is a potent, selective LSD1 inhibitor.

SjDX5-271是一种3 kDa的小肽。SjDX5-271能够抑制TLR4 MyD88 NF-κB信号通路，诱导细胞极化，并减轻肝脏炎症。SjDX5-271还对小鼠有保护作用，防止其受到肝脏缺血-再灌注损伤。

Palmitic acid-13C (C1, C2, C3, and C4 labeled) is intended for use as an internal standard for the quantification of palmitic acid by GC- or LC-MS. Palmitic acid is a common 16-carbon saturated fat that represents 10-20% of human dietary fat intake and comprises approximately 25 and 65% of human total plasma lipids and saturated fatty acids, respectively.1,2Acylation of palmitic acid to proteins facilitates anchoring of membrane-bound proteins to the lipid bilayer and trafficking of intracellular proteins, promotes protein-vesicle interactions, and regulates various G protein-coupled receptor functions.1Red blood cell palmitic acid levels are increased in patients with metabolic syndrome compared to patients without metabolic syndrome and are also increased in the plasma of patients with type 2 diabetes compared to individuals without diabetes.3,4 1.Fatima, S., Hu, X., Gong, R.-H., et al.Palmitic acid is an intracellular signaling molecule involved in disease developmentCell.
