F-11,461

F-11,461 is a drug that acts as an agonist of the 5-HT_1A receptor (K_i = 1.36 nM) that has been used as a radioligand in PET studies. It possesses modest affinity for the 5-HT₇ (K_i = 9.1 nM) and D₄ (K_i = 8.5 nM) receptors, although the interaction of F-11,461 with these receptors is not detectable with PET due to their relative scarcity in the brain.^[1]
