Efficient anti-bacterial hydroxy acid ester oligomer

Abstract

An efficient anti-bacterial hydroxy acid ester oligomer of the present invention has a general structural formula (I). Starting from the design of molecular structure, the present invention rationally designs the end group and chain length structure of the substance of formula (I), and controls its clogP value, so that the substance of formula (I) of the present invention reaches an appropriate size, which maximizes the ability of the substance of formula (I) to penetrate into the bacteria and destroy the bacterial cell membrane, thereby achieving high anti-bacterial efficiency. By precisely designing the molecular structure, the present invention regulates the hydrophilicity and hydrophobicity of the hydroxy acid ester oligomer to obtain a bio-based anti-bacterial agent with controllable water solubility.
