Conjugates of gonadotropin releasing hormone (GnRH) with carminic acid: Synthesis, generation of reactive oxygen species (ROS) and biological evaluation Original Research Article

We synthesized two carminic acid (7-α-d-glucopyranosyl-9,10-dihydro-3,5,6,8-tetrahydroxy-1-methyl-9,10-dioxo-2-anthracene carboxlic acid, CA)-GnRH conjugates to be used as a model for potential photoactive targeted compounds. CA was conjugated to the ε-amino group of [d-Lys6]Gn
