Disclosed is a peptide nucleic acid monomer as well as a corresponding peptide nucleic acid molecule. The monomer comprises a terminal amino group and a terminal group A. The terminal amino group and the terminal group A are connected by an aliphatic moiety. The main chain of this aliphatic moiety is free of groups that are charged under physiological conditions. The terminal group A is one of —COOH, —COOR

and R4 being H or an aliphatic, alicyclic, aromatic, arylaliphatic or arylalicyclic group, and X being a halogen atom. The terminal amino group is substituted by an aliphatic group with a main chain of at least two carbon atoms and optionally 0 to a bout 2 heteroatoms selected from the group N, O, S, Se and Si. The main chain has a polar head group Z.
揭示了一种肽核酸单体以及相应的肽核酸分子。该单体包括一个末端氨基团和一个末端基团A。末端氨基团和末端基团A由一个脂肪族基团连接。该脂肪族基团的主链在生理条件下不带电。末端基团A是以下之一:—COOH、—COOR3、—COX、—COSR3、—CN、—CONH2、—CONHR3、—CONR3、R4,其中R3和R4为H或脂肪族、脂环、芳香、芳香脂肪或芳香脂环基团,X为卤素原子。末端氨基团被一个至少有两个碳原子的脂肪族基团取代,可选地含有0到大约2个来自N、O、S、Se和Si组的杂原子。主链具有一个极性头基团Z。
