Docking-based virtual screening of potential human P2Y12 receptor antagonists.

Area of Science:

• Pharmacology
• Biochemistry
• Computational Chemistry

Background:

• Platelets are crucial for hemostasis, but their dysfunction can cause arterial thrombosis.
• P2Y12, a platelet adenosine diphosphate receptor, is a target for anti-coagulation agents, yet current inhibitors have limitations.
• Improved anti-thrombotic therapies are needed to address the shortcomings of existing P2Y12 inhibitors.

Purpose of the Study:

• To develop a structural model of the human P2Y12 receptor.
• To virtually screen chemical compound libraries for potential P2Y12 inhibitors.
• To identify novel compounds with high binding affinity for P2Y12 as potential anti-coagulation agents.

Main Methods:

• Homology modeling was used to construct the three-dimensional structure of human P2Y12, utilizing the G-protein coupled receptor Meleagris gallopavo β1 adrenergic receptor structure.
• Virtual screening was performed against three subsets (lead-like, fragment-like, drug-like) of the ZINC database.
• Binding affinity analysis of top-scoring compounds was conducted to understand their interaction with the P2Y12 receptor.

Main Results:

• A structural model of the human P2Y12 receptor was successfully generated.
• Virtual screening identified several compounds with potential high binding affinity to P2Y12.
• Top-ranked compounds exhibited a hydrophobic structure with polar atoms, interacting primarily via hydrophobic forces within the ligand-binding site.

Conclusions:

• The study provides a valuable P2Y12 structure model for the rational design of anti-platelet drugs.
• Several promising chemical compounds were identified for further investigation as potential anti-coagulation inhibitors.
• These findings pave the way for developing more effective anti-platelet therapies targeting P2Y12.
