These are essential to ensureproper formulation and optimize bioavailability at the PSMA actionsite on PCa cells. Nevertheless, a fewyears later, a company named Endocyte, Inc. investigated several LTDsof Tub (hydrazide form, TubH), with EuK (34–36, Figure ) followingthe previous context. In the Endocyte’s LTDs, the pharmacophore DUPA was replaced with EuK and connectedto the linker with a more biologically stable urea bond instead ofa peptide bond. Here, FOLH1 is linked to posterior cortical atrophy.
