Enprofylline 是一种选择性和竞争性的A2B受体拮抗剂，Ki为 7 μM。Enprofylline 还是一种磷酸二酯酶 (phosphodiesterase) 抑制剂。Enprofylline 可用于哮喘、慢性阻塞性肺疾病的研究
| 生物活性 | Enprofylline acts as a selective and competitiveA2B receptorantagonist with theKiof 7 μM. Enprofylline also acts as aphosphodiesteraseinhibitor. Enprofylline can be used for the research of asthma, chronic obstructive pulmonary disease[1][2][3]. |

体外研究
(In Vitro) | Enprofylline (300 μM) completely blocks the release of IL-8 by N-ethylcarboxamidoadenosine (NECA)[1].
Enprofylline (10 μM) inhibits NECA (10 μM) induced proliferation in a concentration-dependent manner[2].
Cell Proliferation Assay[2] | Cell Line: | Human retinal endothelial cells (HRECs) | | Concentration: | 10 μM | | Incubation Time: | 24, 48, 72 hours | | Result: | NECA (10 μM) induced a time-dependent increase in HREC proliferation as measured by cell counts, achieving approximately 80% of the density of cells exposed to normal growth medium for 3 days.
Enprofylline (10 μM) completely blocked the proliferative effect of NECA when added concurrently with the analogue. |

体内研究
(In Vivo) | Enprofylline increases heart rate (HR). Injection of Enprofylline (7.5 and 30 mg/kg) increases HR in male WT mouse from 529±23 to 590±20 and 562±20 after the low and high dose, respectively[3].
A high dose of Enprofylline (30 mg/kg) also decreases temperature compared with saline injection in female (but not in males) WT mice, but a low dose (7.5 mg/kg) has little effect on mouse temperature[3].
| Animal Model: | A1RKO mice (were cross-bred to C57BL/6 mice for six generations) and A2ARKO mice (were backcrossed to C57BL/6 mice for more than 10 generations)[3] | | Dosage: | 30 mg/kg | | Administration: | Intraperitoneally injected (bolus) at 2-h intervals | | Result: | Increased HR in male WT mouse from 529±23 to 590±20 and 562±20 after the low (7.5 mg/kg) and high dose (30 mg/kg), respectively. |
