title: Structure-activity relationship in PAF-acether. 2. rac-1-O-Octadecyl-2-O-acetyl-3-O-[gamma-(dimethylamino)propyl]glycerol .
abstract: Two products without phosphoryl groups, 1-O-octadecyl-2-O-acetyl-3-O-[gamma-(dimethylamino)propyl]glycerol and its quaternary salt, were synthesized from 1-O-octadecyl-2-O-benzylglycerol. In comparison with PAF-acether, they lost aggregating and bronchoconstrictive activities and did not show any antagonistic effects.
