P2Y1 antagonist 4

P2Y1 antagonist 4 is a selective P2Y1 receptor antagonist with excellent blood-brain barrier (BBB) penetration. P2Y1 antagonist 4 inhibits P2Y1 receptor-mediated cytosolic Ca²⁺ increase (IC₅₀ = 1.95 μM) and platelet aggregation (IC₅₀ = 3.24 μM) induced by ADP in rabbit washed platelets. P2Y1 antagonist 4 significantly upregulates the level of nuclear Nrf2 protein in H2O2-treated HT22 cells. P2Y1 antagonist 4 reduces myocardial infarct size in a mouse acute myocardial infarction (MI) model. P2Y1 antagonist 4 can be used for the study of ischemic stroke and myocardial infarction.

All P2Y Receptor Isoforms :

In Vitro

P2Y1 antagonist 4 (Compound 12g) inhibits P2Y1 receptor-mediated cytosolic Ca²⁺ increase (IC₅₀ = 1.95 μM) and platelet aggregation (IC₅₀ = 3.24 μM) induced by ADP in rabbit washed platelets^[1].
P2Y1 antagonist 4 (10 μM, 24 h) significantly increases cell viability in H2O2-induced oxidative stress-injured HT22 hippocampal neurons^[1].
P2Y1 antagonist 4 (10 μM, 16 h) significantly upregulates the level of nuclear Nrf2 protein in H2O2-treated HT22 cells^[1].

In Vivo

P2Y1 antagonist 4 (Compound 12g) (5-20 mg/kg, i.v., single dose immediately post-LAD ligation, 24 h evaluation) reduces myocardial infarct size dose-dependently and lowers serum CK-MB/LDH in male C57BL/6 mice^[1].

Animal Model:

The chest was opened at the fourth costal space of the left chest wall along the left edge of the sternum to expose the heart, and a 7-0 silk thread was threaded through a live knot 2 mm from the left anterior descending coronary artery (LAD) branch for permanent ligation in Male C57BL/6 mice (20-25 g, 5-6 weeks old)^[1]
Dosage:

5, 10, 20 mg/kg
Administration:

i.v., single dose immediately post-LAD ligation, 24 h evaluation
Result:

Reduced myocardial infarct size dose-dependently.
Alleviated myocardial cytolysis and reduces fibrosis.

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.
