Propargylcholine (bromide)

Propargylcholine bromide is a choline analogue containing terminal propargyl that can be incorporated into all classes of Choline-containing phospholipids such as phosphatidylcholine and sphingomyelin, labeling Choline-containing phospholipids. Propargylcholine bromide-labeled phospholipid molecules can be visualized in cells with high sensitivity and spatial resolution. Propargylcholine bromide can be used as a molecular tool to study the biochemical and metabolic processes of Choline-containing phospholipids in cells[1][2].

Propargylcholine bromide (10, 50 µM; 24 h) 掺入 NIH 3T3细胞中，并以浓度依赖性方式显示强染色 (用 Alexa568 叠氮化物固定并染色)[1]。 Immunofluorescence[1] Cell Line: NIH 3T3 cells Concentration: 10, 50 µM Incubation Time: 24 h Result: Showed strong staining proportional in intensity to the concentration of added Propargylcholine bromide.

Propargylcholine bromide (P-Cho; 3.5-4.0 mg/kg; i.p; single daily for 6 days) 在恒河猴中给药后 1 周内有效掺入新合成的髓磷脂并持续存在超过 6 周[2]。
