摘要
Inspired by naturally occurring DNA-binding proteins and their artificial alpha-peptidic mimics reported to date, a research project was initiated aiming at creating a new class of beta-peptides capable of binding to and ultimately regulating the functions of DNA. As an initial foray, a beta(3)-pentadecapeptide 1, which bears H-bonding Asn side chains and positively charged Lys side chains, was designed and synthesized on the solid support. DNA-Complexation studies by means of circular dichroism and DNA-melting-temperature measurements revealed the first preliminary indications that support the existence of ordered interactions between beta-peptides and DNA.
