Data Sheet 产品使用指南

Dopamine hydrochloride (ASL279) 是在脑黑质，脑腹侧被盖区和下丘脑中产生的一种儿茶酚胺类神经递质，在大脑和身体中起着重要作用。Dopamine hydrochloride (ASL279) 通过 D2 多巴胺受体 (D2 dopamine receptor) 来诱导 VEGFR2 的内吞作用，这对于促进血管生成是至关重要的。

生物活性

Dopamine hydrochloride (ASL279) is a catecholamine neurotransmitter that is produced in the substantia nigra, ventral tegmental area, and hypothalamus of the brain. Dopamine hydrochloride (ASL279) plays several important roles in the brain and body. Dopamine hydrochloride (ASL279) acts through D2 dopamine receptors to induce endocytosis of VEGFR2, which is critical for promoting angiogenesis.

体外研究

Vascular permeability factor/vascular endothelial growth factor (VPF/VEGF) strongly stimulates human umbilical vein endothelial cells (HUVECs) proliferation. The stimulatory effect of VPF/VEGF is abrogated by Dopamine (1 µM; 24hours).

Cell Proliferation Assay

Cell Line:	HUVECs
Concentration:	1 µM
Incubation Time:	24 hours
Result:	Inhibited VPF/VEGF-induced HUVEC proliferation specifically through its D2 receptor.

体内研究

Dopamine (50 mg/kg; i.p. injection; days 1-7) strongly and selectively inhibits the vascular permeabilizing and angiogenic activities of VPF/VEGF.

Animal Model:	Syngeneic C3Heb/FeJ mice with MOT ascites tumors
Dosage:	50 mg/kg
Administration:	I.p. injection; 7 days
Result:	Corresponding to ~5% of the median lethal dose (LD₅₀) in mice) beginning at 24 hours after tumor-cell injection and continuing daily for 7 days.
