Severe malaria has been, in part, associated with the ability of parasite infected red blood cells to aggregate together with uninfected erythrocytes to form rosettes via the parasite protein PfEMP-1. In this study, inhibitors of rosetting by the Plasmodium falciparum strain R-29, based on chemically modified heparin polysaccharides (IC50 = 1.97 x 10(-2) and 3.05 x 10(-3) mg center dot mL(-1)) and their depolymerized, low molecular weight derivatives were identified with reduced anticoagulant and protease (renin, pepsin, and cathepsin-D) activities. Low molecular weight derivatives of the two most effective inhibitors were shown to have distinct minimum size and strain-specific structural requirements for rosette disruption. These also formed distinct complexes in solution when bound to platelet-factor IV.
