ABSTRACT:
Compounds of the present invention include cell growth inhibitors which are peptides of Formula I,in-line-formulae description="In-line Formulae" end="lead"?A-B-D-E-F-(G)r-(K)s-L   (I),in-line-formulae description="In-line Formulae" end="tail"?and acid salts thereof, wherein A, B, D, E, F, G and K are α-amino acid residues, and s and r are each, independently, 0 or 1. L is a monovalent radical, such as, for example, an amino group, an N-substituted amino group, a β-hydroxylamino group, a hydrazido group, an alkoxy group, a thioalkoxy group, an aminoxy group, or an oximato group. The present invention also includes a method for treating cancer in a mammal, such as a human, comprising administering to the mammal an effective amount of a compound of Formula I in a pharmaceutically acceptable composition.
