Title:
METHOD FOR OPTIMIZING VIRUS MEMBRANE FUSION INHIBITOR, BROAD-SPECTRUM ANTI-CORONAVIRUS LIPOPEPTIDE AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/155318
Kind Code:
A1
Abstract:
Provided are a broad-spectrum anti-SARS-CoV-2 lipopeptide, a preparation method therefor, a virus membrane fusion inhibitor comprising the lipopeptide, and use of the lipopeptide in the preparation of a pharmaceutical composition for preventing and treating diseases caused by the coronavirus. The structure of the lipopeptide is shown as formula (I) or formula (II), wherein X1 is an amino protection group; X2 is a polypeptide, whose amino acid sequence is (EAAAK)n or A[(EAAAK)n]A, wherein n is a natural number less than 5 and indicates the number of repetitions of the EAAAK sequence; X3 is lysine or cysteine or 2,3-diaminopropionic acid or ornithine or 2,4-diaminobutanoic acid or 2,7-diaminoheptanoic acid; X4 is a lipophilic compound group; X5 is a carboxy-terminal protecting group.
