    Abstract: Compounds of the present invention include cell growth inhibitors which are peptides of Formula IA-B-D-E-F-G(I)and acid salts thereof, wherein A, D, and E are alpha -amino acid residues, B is an alpha -amino acid residue or an alpha -hydroxy acid residue, F is an aminobenzoic acid residue or an aminocycloalkanecarboxylic acid residue, and G is a monovalent radical, such as, for example, a hydrogen atom, an amino group, an alkyl group, an alkylene alkyl ether, an alkylene alkyl thioether, an alkylene aldehyde, an alkylene amide, a beta -hydroxylamino group, a hydrazido group, an alkoxy group, a thioalkoxy group, an aminoxy group, an oximato group, an alkylene aryl group, an alkylene ester, an alkylene sulfoxide or an alkylene sulfone. Another aspect of the present invention includes pharmaceutical compositions comprising a compound of Formula I and a pharmaceutically acceptable carrier. An additional embodiment of the present invention is 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.
