Abstract

Compounds of Formula (Ia)

wherein R is a C₆-C₁₂ substituted or unsubstituted aryl, a C₆-C₁₂ substituted or unsubstituted heteroaryl, a C₁-C₆ substituted or unsubstituted alkyl or —NR′R′,

• Q is C(O), O, NR′, S, S(O)₂, C(O)₂ (CH2)p
• Y is C(O), O, NR′, S, S(O)₂, C(O)₂ (CH2)p
• Z is H or C₁-C₄ alkyl,
• R′ is H, C(O), S(O)₂, C(O)₂, a C₆-C₁₂ substituted or unsubstituted aryl, a C₆-C₁₂ substituted or unsubstituted heteroaryl or a C₁-C₆ substituted or unsubstituted alkyl, when substituted, aryl, heteroaryl and alkyl are substituted with halogen, C₆-C₁₂ heteroaryl, —NR′R′ or COOZ, which have diagnostic and therapeutic properties, such as the treatment and management of prostate cancer and other diseases related to NAALADase inhibition. Radiolabels can be incorporated into the structure through a variety of prosthetic groups attached at the X amino acid side chain via a carbon or hetero atom linkage.
