Abstract
Biologically active amphiphilic peptides including one of the following basic structures: I. R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.1 --R.sub.2 --R.sub.1 --R.sub.1 ; II. R.sub.2 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.2 --R.sub.2 ; III. R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.1 --R.sub.2 --R.sub.3 ; IV. R.sub.1 --R.sub.2 --R.sub.1 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.4 ; V. R.sub.1 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.3 ; or VI. R.sub.1 --R.sub. 1 --R.sub.3 --R.sub.2 --R.sub.1 --R.sub.1 --R.sub.1 --R.sub.1 --R.sub.1 --R.sub.1 --R.sub.2 --R.sub.1 --R.sub.1 --R.sub.2 --R.sub.2 --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 is a hydrophobic amino acid and R.sub.2 is a basic hydrophilic or neutral hydrophilic amino acid, R.sub.3 is a neutral hydrophilic amino acid, and R.sub.4 is a neutral hydrophilic amino acid or proline. There is also provided a biologically active amphiphilic peptide having a structural formula selected from the group consisting of: (a) R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 ; (b) R.sub.1 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 ; (c) R.sub.2 --R.sub.1 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 ; (d) R.sub.2 --R.sub.2 --R.sub.1 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 ; and (e) R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 --R.sub.2 --R.sub.2 --R.sub.1 ; wherein R.sub.1 and R.sub.2 are are hereinabove described. Such peptides may be employed as pharmaceuticals.
