title: Surface activity and human blood platelet aggregation-inhibitory potency.
abstract: Surface and interfacial activity is correlated with molecular constitution and inhibitory potency of mono- and bis(carbamoylpiperidino)alkanes and aralkanes, and of some corresponding quaternary pyridinium congeners, in ADP-induced human blood platelet aggregation. The measurements of surface and interfacial tension were carried out at concentrations and pH-values approximating those employed in the hemodynamic study. The effect of changes in chemical structure, ranging from relatively minor variations in a specific functional group to the alteration of major components in molecular constitution, was examined and interpreted in terms of contemporary theoretical chemistry.
