應用

Diisopropylfluorophosphate has been used:
  • in combination with inactivated thrombin in Affi-Gel 10 column for the purification of recombinant human thrombomodulin with its chondroitin sulfate chain (shrTMCSA)
  • for inducing status epilepticus (SE) in adult rats
  • as an irreversible serine protease inhibitor in human neutrophil subcellular fractions

生化／生理作用

丝氨酸蛋白酶（如胰蛋白酶和胰凝乳蛋白酶）和乙酰胆碱酯酶的强效抑制剂；还抑制组织蛋白酶 G、胆碱脂酶、凝血因子 Xa、白细胞弹性蛋白酶、胰弹性蛋白酶、组织激肽释放酶、血纤维蛋白熔酶、枯草杆菌蛋白酶以及凝血酶。乙酰胆碱酯酶的抑制作用使该化合物具有特别强的毒性。抑制由篦麻毒素和细菌毒素诱导的细胞凋亡。

分析報告

使用浓度通常为 0.10mM。苯甲基磺酰氟 (PMSF) 是一种更安全的丝氨酸蛋白酶替代抑制剂。

其他說明

Stored properly at 2-8°C, in an unopened bottle, DIFP should be stable for a minimum of two years. DIFP
is unstable when exposed to moisture. DIFP will develop a dark yellow color upon decomposition.
