Suramin

trypanosomal glycolytic enzyme lipoprotein

https://en.m.wikipedia.org/wiki/Suramin

The mechanism of action for suramin is unclear, but it is thought that parasites are able to selectively uptake suramin via receptor-mediated endocytosis of drug that is bound to low-density lipoproteins and, to a lesser extent, other serum proteins. Once inside parasites, suramin combines with proteins, especially trypanosomal glycolytic enzymes, to inhibit energy metabolism.
