Abstract
A nano small peptide FH and its use in preparation of drugs for treating and preventing fundus vascular diseases are provided. The artificially synthesized nano small peptide has a molecular formula of X-FFVLK-KQKRPRH (SEQ ID NO: 1), wherein the X is dodecanoyl, tetradecanoyl, hexadecanoyl, or octadecanoyl. The nano small peptide of the present invention can specifically select receptors to encapsulate sSema4D protein, and the concentration of sSema4D is effectively reduced, so that the sSema4D is unable to bind to any receptors, thus changing the shortcoming of few inhibitory targets of antibody drugs. The nano small peptide molecule with a simple structure can be mixed with antibody drugs without causing mutual immune reactions, so as to achieve the effect of reducing multiple pro-angiogenesis molecules.
