Composition for long-acting peptide analogs
First Claim
1. A composition comprising a peptide analog having a general formula:
- A-(Cm)x-peptide, wherein;
a. Cm is any one of glycine, alanine, lysine, and arginine;
b. x is an integer from 3-6;
c. A is a chemical group or moiety comprising an alkyl group with 6 to 36 carbon units with a —
OCH(CH3)CO—
linker attached to -(Cm)x-peptide; and
d. the A-(Cm)x-peptide has lower biological activity in cell culture than the parent peptide in the absence of serum, wherein the peptide has at least 8 amino acids and is not SEQ ID NO;
53, or wherein the peptide is auristatin.

Abstract
The invention describes compositions of peptide analogs that are active in blood or cleavable in blood to release an active peptide. The peptide analogs have a general formula: A-(Cm)x-Peptide (SEQ ID NO: 76), wherein A is hydrophobic moiety or a metal binding moiety, e.g., a chemical group or moiety containing 1) an alkyl group having 6 to 36 carbon units, 2) a nitrilotriacetic acid group, 3) an imidodiacetic acid group, or 4) a moiety of formula (ZyHisw)p (SEQ ID NO: 50), wherein Z is any amino acid residue other than histidine, His is histidine, y is an integer from 0-6; w is an integer from 1-6; and p is an integer from 1-6; wherein if A has alkyl group with 6 to 36 carbon units x is greater than 0; and Cm is a cleavable moiety consisting of glycine or alanine or lysine or arginine or N-Arginine or N-lysine, wherein x is an integer between 0-6 and N may be any amino acid or none. The peptide analogs are complexed with polymeric carrier to provide enhanced half-life.
