    摘要: A biologically active peptide which includes the following structure:R.sub.1 -R.sub.1 -R.sub.1 -R.sub.4 -R.sub.1 -R.sub.1 -R.sub.2 -R.sub.1 -R.sub.1 -R.sub.1 -R.sub.1 -R.sub.1 -R.sub.1 -R.sub.1a -R.sub.1 -R.sub.1 -R.sub.3 -R.sub.2 R.sub.2 -R.sub.1aR.sub.1 and R.sub.1a are hydrophobic amino acids, R.sub.2 is a basic hydrophilic amino acid, R.sub.3 is a neutral hydrophilic amino acid, and R.sub.4 is hydrophobic or basic hydrophilic amino acid. Preferably, R.sub.1a is cysteine.Examples of peptides have the following structural formulae:(SEQ ID NO:1);(SEQ ID NO:2);(SEQ ID NO:3);(SEQ ID NO:4);(SEQ ID NO:5); and(SEQ ID NO:6).The peptide may be employed in a pharmaceutical composition.
