Ion-channel forming peptides
摘要:
A biologically active peptide which includes the following structure:R.sub.1 --R.sub.1 --R.sub.1 --R.sub.3 --R.sub.5 --R.sub.1 --R.sub.1 --R.sub.1 --R.sub.1 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.1 R.sub.3 --R.sub.1 --R.sub.4 --R.sub.1 --R.sub.3 --R.sub.4 --R.sub.1 --R.sub.1.R.sub.1 is a hydrophobic amino acid, R.sub.2 is a basic hydrophilic amino acid, and R.sub.3 is a neutral hydrophilic amino acid, R.sub.4 is a hydrophobic or basic hydrophilic amino acid, and R.sub.5 is a hydrophobic, basic hydrophilic, or neutral hydrophilic amino acid.Examples of such peptides include the following:(SEQ ID NO:1)--NH.sub.2 ;(SEQ ID NO:2)--NH.sub.2 ;(SEQ ID NO:3)--NH.sub.2 ;(SEQ ID NO:4)--NH.sub.2 ;(SEQ ID NO:5)--NH.sub.2 ;(SEQ ID NO:6)--NH.sub.2 ;(SEQ ID NO:7)--NH.sub.2 ; and(SEQ ID NO:8).The peptides may be employed in pharmaceutical compositions.
