The synthetic and structure-activity relationship (SAR) studies of new
non-peptide GPIIb/IIIa antagonists (1a-f and 3) were conducted by rep
lacing one amide bond of NSL-95300 (2) with an (E)-double bond or an e
none group. NSL-95315 (1a) and NSL-95317 (3) showed the inhibitory act
ivity for collagen-induced human platelet aggregation with IC50 values
of 0.25 mu M and 0.21 mu M, respectively. (C) 1997 Elsevier Science L
