PubMed Abstract:
Expedited structure-based optimization of the initial fragment hit 1 led to the design of ( R )- 7 (AZD2716) a novel, potent secreted phospholipase A ₂ (sPLA ₂) inhibitor with excellent preclinical pharmacokinetic properties across species, clear in vivo efficacy, and minimized safety risk. Based on accumulated profiling data, ( R )- 7 was selected as a clinical candidate for the treatment of coronary artery disease.
