The introduction of a carboxylate group in the azolyl - ring leads to a remarkable reduction of the kidney ( > 89 % ) and liver ( > 91 % ) accumulation for ( 99m ) Tc ( CO ) 3 - Pz ( 3 ) - beta AlaNleCycMSH ( hex ) and ( 99m ) Tc ( CO ) 3 - Pz ( 4 ) - beta AlaNleCycMSH ( hex ) when compared to the radiopeptide ( 99m ) Tc ( CO ) 3 - Pz ( 1 ) - beta AlaNleCycMSH ( hex ) , where that group is absent .
