WebFeb 1, 2013 · The in vitro affinity of twenty-two compounds for the GABA(A) receptor was measured. Compounds containing a fluoroalkyl amide or a longer chain ester group were eliminated due to low potency. The fluorine-18 radiochemistry of one compound from each structural type was assessed to confirm that an automated radiosynthesis in good yield … WebThe basic structure of PFAS, shown in Figure 1, includes a carbon-fluorine chain, known as the tail, and a functional group at the end of the chain, known as the head (ATSDR, 2024a).
