Pentoxifylline (BL-191) 是一种血液流变学改善剂。Pentoxifylline 是一种具有口服活性的，非选择性的磷酸二酯酶 (PDE) 抑制剂，具有免疫调节、抗炎、血液流变学改善、抗纤溶和抗增殖作用。Pentoxifylline 可用于研究周围血管疾病、脑血管疾病和其他一些涉及局部微循环缺陷的疾病。
PDE
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.

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. |
化学性质
