MRS4719

MRS4719 is a potent P2X4 receptor antagonist with an IC₅₀ value of 0.503 μM for human P2X4 receptor. MRS4719 can reduce infarct volume and reduce brain atrophy, showing neuroprotective and neuro-rehabilitative activities in ischemic stroke model. MRS4719 also reduces ATP-induced [Ca²⁺]_i influx in primary human monocyte-derived macrophages. MRS4719 can be used to research ischemic stroke.

Biological Activity

Description

IC₅₀ & Target

IC₅₀: 0.503 μM (P2X4 receptor)^[1]

All P2X Receptor Isoforms :

In Vitro

MRS4719 (compound 21u) (0.1, 0.3, 0.6, 1.0 and 3.0 μM; 15 min) inhibits P2X4R-mediated Ca²⁺ influx in primary human monocyte-derived macrophages.^[1].

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

In Vivo

MRS4719 (compound 21u) (0.5-3 mg/kg; 3 days continuous infusion with an Alzet minipump) reduce infarct volume and reduced brain atrophy; does not improve motor coordination and balance as assessed using rotarod; improves learning and memory after stroke^[1].

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

Animal Model:

Male and female young C57B/6 mice (8-12 weeks; induced transient focal cerebral ischemia by a 60 min right middle cerebral artery occlusion)^[1]
Dosage:

0.5, 1.5 and 3 mg/kg
Administration:

3 days continuous infusion with an Alzet minipump
Result:

Caused significant neuroprotection using total hemispheric infarct volume size at doses 1.5 and 3.0 mg/kg.

Animal Model:

Middle-aged C57B/6 mice (11-12 month-old; induced transient focal cerebral ischemia by a 60 min right middle cerebral artery occlusion)^[1]
Dosage:

1.5 and 3 mg/kg
Administration:

3 days continuous infusion with an Alzet minipump
Result:

Did not improve motor coordination and balance as assessed using rotarod.

Animal Model:

Middle-aged C57B/6 mice (11-12 month-old; induced transient focal cerebral ischemia by a 60 min right middle cerebral artery occlusion)^[1]
Dosage:

3 mg/kg
Administration:

3 days continuous infusion with an Alzet minipump
Result:

Improved dose-dependently learning and memory after stroke and reached statistical significance at a dose of 3 mg/kg.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
