diacylglycerol phosphorylation

Dioctanoylglycol (ethane-1,2-diyl dioctanoate) 是二酰基甘油类似物，也是二酰基甘油激酶 (DGK) 抑制剂，其Ki=为58 μM。

Dioctanoylphosphatidic acid sodium 是一种化学化合物，它不仅作为二酰甘油和溶血磷脂酸的前体在调节吞噬细胞的呼吸爆发中发挥作用，还可以影响雷帕霉素哺乳动物靶点 (mTOR) 的磷酸化。此外，该化合物还能增强在组蛋白去乙酰化酶抑制剂 (HDACI) 抑制下的胆囊癌细胞活力。它是通过磷脂酶 D 从甘油磷脂中分离出来的。

1,2-Dioleoyl-rac-glycerol-13C3 is intended for use as an internal standard for the quantification of 1,2-dioleoyl-rac-glycerol by GC- or LC-MS. 1,2-dioleoyl-rac-glycerol is a diacylglycerol that contains oleic acid at the sn-1 and sn-2 positions. It effectively binds the C1 domain to activate conventional protein kinase C forms and serves as a substrate for diacylglycerol kinases and multisubstrate lipid kinase.1,2,3 |1.

Phosphatidylinositols, comprising about 10% of total cellular phospholipids, are glycerophospholipids featuring a glycerol backbone, two non-polar fatty acid tails (primarily C16:0 and C18:0), and a polar inositol head group. Synthesized from cytidine diphosphate diacylglycerol (CPD-DAG) and myoinositol via phosphoinositol synthase, these compounds play pivotal roles in cellular processes, including calcium regulation, vesicle trafficking, mitogenesis, cell survival, and actin rearrangement. Phosphorylation of their inositol rings produces phosphoinositides, crucial for these cellular functions. [Matreya, LLC. Catalog No. 1048]
