Stearic acid (Cetylacetic acid) 是长链饱和脂肪酸，存在于许多动植物油脂中。

Dios-Arg is a steroid-based cationic lipid that contains a diosgenin skeleton coupled to an L-arginine head group. It forms a complex with plasmid DNA and decreases plasmid DNA migration in an agarose-gel retardant assay at charge ratio greater than or equal to 4. Dios-Arg facilitates transfection of plasmid DNA into H1299 and HeLa cells in the presence and absence of fetal bovine serum, an effect that is reversed by the lipid raft-mediated endocytosis inhibitor methyl-β-cyclodextrin and the caveolae-mediated endocytosis inhibitor genistein . It has been used, coupled to 1,2-dioleoyl-sn-glycero-3-PE , to bind siRNA and plasmid DNA to form cationic lipid nanoparticles for intracellular transport. Dios-Arg is cytotoxic to H1299 and HeLa cells (IC50s = 83.5 and 74.1 μg/ml, respectively).

Cho-Arg is a steroid-based cationic lipid that contains a cholesterol skeleton coupled to an L-arginine head group. It forms a complex with plasmid DNA and decreases plasmid DNA migration in an agarose-gel retardant assay at charge ratios greater than or equal to 4. Cho-Arg facilitates transfection of plasmid DNA into H1299 and HeLa cells in the presence or absence of fetal bovine serum, an effect that is reversed by the lipid raft-mediated endocytosis inhibitor methyl-β-cyclodextrin and the caveolae-mediated endocytosis inhibitor genistein . It is cytotoxic to H1299 cells (IC50 = 88.5 μg/ml).

Stearic acid-18,18,18-d3 是 Stearic acid 的氘代化合物。Stearic acid 的 CAS 号为 57-11-4。Stearic acid是长链饱和脂肪酸，存在于许多动植物油脂中。

CDK-IN-9 (compound 24) 是一种 CDK 的有效抑制剂。CDK-IN-9 也是一种能够诱导 CDK12 和 DDB1 相互作用的分子胶， 能够作用于 CDK2 E (IC50: 4 nM) 。CDK-IN-9 能够导致细胞周期蛋白 K (cyclin K) 的多泛素化及其随后的降解。CDK-IN-9 可以利用去磷酸化视网膜母细胞瘤蛋白和RNA 聚合酶 II，进而诱导细胞凋亡 (apoptosis)。
