PEPTIDE NUCLEIC ACID (PNA) MONOMERS WITH AN ORTHOGONALLY PROTECTED ESTER MOIETY
-
Paragraph 00359, (2018/10/19)
This application pertains to orthogonally protected esters of peptide nucleic acid (PNA) monomers, which ester groups can be removed under conditions that permit typical backbone and side chain acid- and base-labile protecting groups to remain substantially intact thereby permitting the high yield of PNA monomer carboxylic acids that are suitable for use in PNA oligomer synthesis. Exemplary ester groups include, but are not limited to, 2,2,2-trichloroethyl (TCE), 2,2,2-tribromoethyl (TBE), 2-bromoethyl (2-BE) and 2-iodoethyl groups (2-IE). This invention also pertains to novel methods for the synthesis of Backbone Ester compounds and related Backbone Ester Acid Salts.

The molecular recognition of carbohydrates and proteins mediates a wide range of physiological processes and the development of synthetic carbohydrate receptors ("synthetic lectins") constitutes a key advance in biomedical technology. In this article we report a synthetic lectin that selectively binds to carbohydrates immobilized in a molecular monolayer. Inspired by our previous work, we prepared a fluorescently labeled synthetic lectin consisting of a cyclic dimer of the tripeptide Cys-His-Cys, which forms spontaneously by air oxidation of the monomer. Amine-tethered derivatives of N-acetylneuraminic acid (NANA), β-D-galactose, β-Dglucose and α-D-mannose were microcontact printed on epoxide-terminated self-assembled monolayers. Successive prints resulted in simple microarrays of two carbohydrates. The selectivity of the synthetic lectin was investigated by incubation on the immobilized carbohydrates. Selective binding of the synthetic lectin to immobilized NANA and β-D-galactose was observed by fluorescence microscopy. The selectivity and affinity of the synthetic lectin was screened in competition experiments. In addition, the carbohydrate binding of the synthetic lectin was compared with the carbohydrate binding of the lectins concanavalin A and peanut agglutinin. It was found that the printed carbohydrates retain their characteristic selectivity towards the synthetic and natural lectins and that the recognition of synthetic and natural lectins is strictly orthogonal.
