制备方法与用途

生物活性 (R)-Lisofylline ((R)-Lisophylline) 是一种 Pentoxifylline 代谢产物的 (R)-型对映体,具有抗炎特性。它是一种溶血磷脂酸酰基转移酶 (lysophosphatidic acid acyltransferase ) 抑制剂,IC50 值为 0.6 µM,并能中断 IL-12 信号介导的 STAT4 激活。该化合物适用于研究 1 型糖尿病和自身免疫性疾病。

靶点

  • IC50: 0.6 µM (溶血磷脂酸酰基转移酶)
  • STAT4

体外研究 (R)-Lisofylline 能阻断由 IL-12 引导的 Tb 分化及 T 细胞增殖,但不会影响 APCs 在体外或离体条件下分泌 IL-12 的能力。

体内研究

  • (R)-Lisofylline 减轻了 IL-1β 导致的胰岛细胞胰岛素分泌受损,在 NOD 小鼠中抑制 IFN-γ 生成、糖尿病发病进程及巨噬细胞浸润到胰岛。它改善了 Streptozotocin 治疗大鼠口服葡萄糖耐量测试后的胰岛素反应并降低了血糖水平。
  • (R)-Lisofylline 阻止 NOD 小鼠中 STAT4 磷酸化,中断 IL-12 信号传导,从而防止 β 细胞功能障碍。该化合物还改善了小鼠实验性自身免疫性脑脊髓炎,并在大鼠注射致死剂量的 LPS 后提高了生存率,减轻了猪肺炎引起的肺损伤。
  • 在大鼠气管内给予 IL-1 前给药 (R)-Lisofylline 可减少肺漏出但不会降低肺部中性粒细胞积累。此外,(R)-Lisofylline 还抑制由来自沙门氏菌或大肠杆菌的内毒素刺激的人血中 TNF-α 的释放。

    名称:
    CYP3A4-Mediated Oxidation of Lisofylline to Lisofylline 4,5-Diol in Human Liver Microsomes
    摘要:
    The cytochrome P450s responsible for the conversion of lisofylline, a drug being developed to prevent the complications of high-dose chemotherapy, to lisofylline 4,5-diol, one of two principal metabolites in human liver microsomes, were evaluated. Lisofylline diol formation in microsomes prepared from five adult human livers was biphasic, with respective K-m values of 0.0230 +/- 0.015 and 4.23 +/- 2.8 mM (mean +/- SD) and respective V-max values of 0.0565 +/- 0.052 and 0.429 +/- 0.15 nmol/min/mg of protein. Through studies with isoform selective chemical inhibitors, CYP3A4 was implicated as the low K-m enzyme from 89.0 +/- 11.2% inhibition of lisofylline 4,5-diol formation by troleandomycin at 50 mu M substrate and CYP2A6 was implicated as the high K-m enzyme. The formation of lisofylline 4,5-diol by these enzymes was confirmed with cDNA-expressed human CYP3A4 and CYP2A6.
