资料参考

U-73122 is a potent phospholipase C (PLC) inhibitor with IC50 value of ~6 μM [1].

PLC is a class of membrane-associated enzymes that catalyzes the hydrolysis of a membrane phospholipid, phosphatidylinositol 4,5-bisphosphate (PIP2), to produce two intracellular messengers, diacylglycerol and inositol-triphosphate, which, in turn, mediate the activation of protein kinase C (PKC) and intracellular Ca2+release, respectively. It plays an important role in various signal transduction pathways [1].

U-73122 significantly inhibited recombinant human PLC-β2 with IC50 value of ~6 μM, while showing little effect on PLC-β1, PLC-β3 or PLC-β4. In human neutrophils, U-73122 reduced interleukin-8 and leukotriene B4-induced Ca2+flux and chemotaxis with IC50 values of ~6 μM and ~5 μM, respectively [1].

In rats, U-73122 (30 mg/kg, i.p.) inhibited hind paw swelling by 65% and 80% at 1 h and 3 h post-carrageenan challenge. Moreover, pretreatment of U-73122 (1 mg/kg, 3 mg/kg and 10 mg/kg, respectively, i.v.) effectively suppressed TPA-induced mouse ear edema in a dose-dependent manner [1].

试验操作

Cell experiment:[1]

Cell lines

Human neutrophils

Reaction Conditions

15 min or 3 h incubation

Applications

In human neutrophils, U-73122 reduced interleukin-8 and leukotriene B4-induced Ca2+flux (after 15 min incubation) and chemotaxis (after 3 h incubation) in a concentration-dependent manner, with IC50 values being ~6 μM and ~5 μM, respectively.

Animal experiment:[1]

Animal models

Male Sprague-Dawley rats, ~ 200 g

Dosage form

30 mg/kg

Administered intraperitoneally (i.p.)

Applications

In rats, U-73122 (30 mg/kg, i.p.) inhibited hind paw swelling by 65% and 80% at 1 h and 3 h post-carrageenan challenge. U-73122 significantly inhibited carrageenan-induced inflammation, and its effect was more complete than a 10 mg/kg p.o. dose of indomethacin.
