Journal ArticleDOI
Design of a potent and orally active nonpeptide platelet fibrinogen receptor (GPIIb/IIIa) antagonist.
William E. Bondinell,Richard M. Keenan,William H. Miller,Fadia E. Ali,Andrew Allen,Charles W. De Brosse,Drake S. Eggleston,Karl F. Erhard,R. Curtis Haltiwanger,William F. Huffman,S M Hwang,Dalia R. Jakas,Paul F. Koster,Thomas W. Ku,Chao Pin Lee,Andrew J. Nichols,Stephen T. Ross,J. Samanen,Richard E. Valocik,Janice A. Vasko-Moser,Joseph W. Venslavsky,Angela S. Wong,Chuan-Kui Yuan +22 more
TL;DR: 4 represents the first orally active compound in this series of potent, nonpeptide fibrinogen receptor antagonists and showed high binding affinity for human GPIIb/IIIa and potent antiaggregatory activity in human platelet-rich plasma.
Journal ArticleDOI
Stereoselective syntheses of substituted 5,6-dihydro-2(1H)-pyridinones in polyphosphate media
Charles M. Marson,Urszula Grabowska,Asad Fallah,Timothy Charles Walsgrove,Drake S. Eggleston,Paul W. Baures +5 more
TL;DR: In this article, the scope of the condensation of 3-alkenamides with aryl aldehydes in several phosphate media is examined, and a rationale is proposed regarding gamma-lactam versus delta-Lactam formation.
Journal ArticleDOI
Calcium and magnesium binding to .gamma.-carboxyglutamate and .beta.-carboxyaspartate residues: structures of calcium and magnesium complexes of methylmalonic acid
Journal ArticleDOI
Stereocontrolled construction of condensed gamma-lactam ring-systems by cationic cyclizations - rearrangement of a gamma-lactam to a delta-lactam
Charles M. Marson,Urszula Grabowska,Timothy Charles Walsgrove,Drake S. Eggleston,Paul W. Baures +4 more
TL;DR: In this article, a new condensation of 3-alkenamides with benzaldehyde in acidic media, notably polyphosphoric acid, leads to gamma-lactam rings with high regio-and stereocontrol.
Journal ArticleDOI
Enantiospecific synthesis of (-)-tabtoxinine .beta.-lactam
TL;DR: Key features of the synthetic route include preparation of a new γ-cation amino acid synthon and its use as an electrophile and the one pot conversion of methyl sulfide to the Cbz-protected amine via stereoselective sulfilimine rearrangement and chemoselectives lactone ring opening in spiro lactam.
