ABSTRACT:
An N-terminal substituted peptide or protein having the formula: ##STR1## X is a biologically active amphiphilic ion channel-forming peptide or protein. T is a lipophilic moiety, and preferably, T is: ##STR2## wherein R is a hydrocarbon (alkyl or aromatic or alkylaromatic) having at least 2 and no more than 10 carbon atoms. T is preferably an octanoyl group. W is T or hydrogen. The N-terminal substituted peptides and proteins have improved biological activity against target cells, viruses, and vitally-infected cells.
