Disclosed are certain substituted or unsubstituted pyridyl-containing spirocyclic compounds substituted with both basic and acidic functionality, which are useful in inhibiting platelet aggregation, inhibiting the binding of fibrinogen to blood platelets, and preventing or treating thrombosis
Selective inhibition of coagulation factor VIIa has recently gained attraction as interesting approach towards antithrombotic treatment. Using parallel synthesis supported by structure-based design and X-ray crystallography, we were able to identify a novel series of amidinophenylurea derivatives with remarkable affinity for factor VIIa. The most potent compound displays a K(i) value of 23 nM for factor

Modified amino acids which can serve as precursors in the synthesis of tritium-labelled peptides were prepared and incorporated into biologically active peptides. Thus, p-iodophenylalanine was incorporated at position 4 of H-Met(O2)-Glu-His-Phe-D-Lys-Phe-OH (Org 2766) and in des-Tyr1-γ-endorphin. As a second labelling site, the precursor of L-leucine, L-methallylglycine, was incorporated in both des-Tyr1-γ-endorphin

Inhibition of group IIA secreted phospholipaseA2 (GIIA sPLA2) has been an important objective for medicinal chemists. We have previously shown that inhibitors incorporating the 2-oxoamide functionality may inhibit human and mouse GIIA sPLA2s. Herein, the development of new potent inhibitors by molecular docking calculations using the structure of the known inhibitor 7 as scaffold, are described. Synthesis
The synthesis and biological activity of novel glycoprotein IIb-IIIa antagonists containing the 3,9-diazaspiro[5.5]undecane nucleus an described. The potent activity of these compounds as platelet aggregation inhibitors demonstrates the utility of the spirocyclic structures as central template for nonpeptide RGD mimics.
