Computer Design of Low-Molecular-Weight Inhibitors of Coagulation Factors

Area of Science:

• Pharmacology
• Biochemistry
• Medicinal Chemistry

Background:

• Anticoagulant therapy is crucial for managing thrombotic disorders.
• Current anticoagulants have limitations, driving the search for safer and more effective alternatives.
• Targeting specific coagulation factors (IIa, Xa, IXa, XIa) offers a promising strategy for developing novel anticoagulants.

Purpose of the Study:

• To review the main approaches for discovering new low-molecular-weight inhibitors of coagulation factors IIa, Xa, IXa, and XIa.
• To summarize the findings of studies conducted between 2015 and 2018 in this field.
• To assess the progress towards identifying an "ideal" anticoagulant.

Main Methods:

• Literature review of studies on low-molecular-weight inhibitors.
• Analysis of structure-activity relationships for identified inhibitors.
• Evaluation of inhibitor potency (IC50 < 10 nM) and clinical trial progression.

Main Results:

• Several potent low-molecular-weight inhibitors with IC50 < 10 nM were identified for coagulation factors IIa, Xa, IXa, and XIa.
• Some of these inhibitors have advanced to clinical trials.
• No identified inhibitor currently fulfills all requirements of an "ideal" anticoagulant.

Conclusions:

• Significant progress has been made in identifying potent inhibitors of key coagulation factors.
• The development of "ideal" anticoagulants remains an ongoing challenge.
• Further research is essential to optimize existing candidates and discover new ones meeting clinical needs.
