Molarity Calculator

Diclofenac Sodium (GP 45840) is a potent and nonselective anti-inflammatory agent, acts as a COX inhibitor, with IC50s of 4 and 1.3 nM for human COX-1 and COX-2 in CHO cells, and 5.1 and 0.84 μM for ovine COX-1 and COX-2, respectively. Diclofenac Sodium induces apoptosis of neural stem cells (NSCs) via the activation of the caspase cascade.

Description

Diclofenac Sodium (GP 45840) is a potent and nonselective anti-inflammatory agent, acts as a COX inhibitor, with IC50s of 4 and 1.3 nM for human COX-1 and COX-2 in CHO cells[1], and 5.1 and 0.84 μM for ovine COX-1 and COX-2, respectively[2]. Diclofenac Sodium induces apoptosis of neural stem cells (NSCs) via the activation of the caspase cascade[3].

IC50 & Target[1][2]

Human COX-2

1.3 nM (IC50, in CHO cells)

Human COX-1

4 nM (IC50, in CHO cells)

Ovine COX-2

0.84 μM (IC50)

Ovine COX-1

5.1 μM (IC50)

In Vitro

Diclofenac effectively blocks COX-1 mediated prostanoid production from U937 cell microsomes, with an IC50 of 7±3 nM[1].
Diclofenac (1-60 μM; 1 day) induces neural stem cells (NSCs)death in a concentration-dependent manner[3].
Diclofenac (10-60 μM; 6 hours) increases the expression of cleaved (activated) caspase-3[3].

Cell Line: Neural stem cells (NSCs)
Concentration: 1, 3, 10, 30, 60 μM
Incubation Time: 1 day
Result: Induction of cell death was concentration-dependent and the effect was not saturated at a concentration of up to 60 μM.

Western Blot Analysis[3]

Cell Line: Neural stem cells (NSCs)
Concentration: 10, 30 or 60 μM
Incubation Time: 6 hours
Result: The activation of caspase-3 was increased in a concentration-dependent manner.
In Vivo

Diclofenac (3 mg/kg, b.i.d., for 5 days) significantly increases faecal 51Cr excretion in rats, and such effect is also observed in squirrel monkeys after administrated of 1 mg/kg twice daily for 4 days[1].
Diclofenac (10 mg/kg; administered via oral route just prior to induction of inflammation) shows in vivo anti-inflammatory activity in Wistar rats[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Sprague-Dawley rats (150±200 g)[1]
Dosage: 3 mg/kg
Administration: Oral administration, b.i.d., for 5 days
Result: Resulted in a significant increase in faecal 51Cr excretion.
Animal Model: Wistar rats (150-175 g) bearing Formalin-induced rat foot paw edema model[2]
Dosage: 10 mg/kg
Administration: Administered via oral route just prior to induction of inflammation
Result: Showed in vivo anti-inflammatory activity (% edema inhibition=29.2, 1 h; 22.2, 3 h; 20, 6 h).

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
