Two novel classes of compounds targeting the sigma-2 (sigma(2)) receptor were synthesized, and their bioactivities to binding sigma(1) and sigma(2) receptors were measured. Four novel triazole carboxamide analogues, 24d, 24e, 24f, and 39c, demonstrated high affinity and selectivity for the sigma(2) receptor. These data suggest C-11-labeled versions of these compounds may be potential sigma(2)-selective radiotracers for imaging the proliferative status of solid tumors.
