Preliminary studies on application of library of artificial receptors for differentiation of metabolites in urine of healthy and cancer bearing mice

Acta Pol Pharm. 2014 Nov-Dec;71(6):941-53.

Abstract

A library of artificial receptors formed by the self-organization of N-lipidated peptides attached to the cellulose via m-aminophenylamino-1,3,5-triazine was used for differentiation of metabolites in urine of healthy and cancer bearing mice. The interactions of urine metabolites with the receptors were visualized by using competitive adsorption-desorption of an appropriate reporter dye. Analysis of the binding pattern (fingerprint) of urine metabolites from healthy and from cancer suffering mice showed that there were several structures among 120-elements molecular receptors which were able to differentiate bonded ligands depending on the healthy state. For all three tested types of cancers two structures: Lipid-Pro-Ala-NH-C6H4-NH-DMT-cellulose and Lipid-Arg-Pro-NH-C6H4-NH-DMT-cellulose were selected as diagnostic.
