Sk. Chung et al., SYNTHESIS AND BIOACTIVITIES OF HETEROCYCLIC LIPIDS AS PAF ANTAGONISTS.2., Bioorganic & medicinal chemistry letters, 5(10), 1995, pp. 1097-1102
Conformationally constrained analogues of platelet activating factor i
ncorporating a lipophile and a pyridine-like heterocycle linked to cor
e groups such as 1,1-bis(hydroxymethyl)cyclobutane and 2,4-bis(hydroxy
methyl)-oxetane, -thietane and -azetidine skeletons via hydrogen bond
acceptors such as ether and/or carbamate have been synthesized, and th
eir in vitro and in vivo bioactivitites have indicated potent and sele
ctive PAF antagonism.
