應(yīng)用領(lǐng)域

用途一
該品為血管擴張藥,能改善腦和四肢的血液循環(huán)。小鼠口服LD50為1385mg/kg。

制備方法

方法一
由1,3-溴氯丙烷與乙酰乙酸乙酯在80℃左右環(huán)合得到2-甲基-3-乙氧羰基-5,6-二氫吡喃,再將其開環(huán)、溴化生成1-溴-5-已酮,然后與可可堿鈉鹽縮合制成已酮可可堿。

體外研究

Pentoxifylline (0.1-50 mM; 24-48 hours) inhibits cell proliferation in a dose-dependent manner.
Pentoxifylline (0.5 mM; 12-36 hours) increases apoptosis and decreases autophagy levels in MDA-MB-231 cells.
Pentoxifylline (0.5 mM; 12-36 hours) induces autophagy in MDA-MB-231 cells.
Pentoxifylline (0.5 mM; 24-48 hours) blocks cell cycle at the G0/G1 phase.
Pentoxifylline results in high LC3-II/LC3-ratio.

體內(nèi)研究

Pentoxifylline (200 mg/kg; i.p.) has a protective effect on rats with transient global ischemia and could reduce cognitive impairment.

Animal Model: Adult male Wistar rats 12-13-weeks-old (250-300 g)
Dosage: 200 mg/kg
Administration: Intraperitoneal injection, at 1hr before and 3 hr after ischemia
Result: Significantly improved the spatial memory and effects were significant different from those of sham-operated and vehicle groups.
