[5] Other ligands for other parts of the serotonin system used in PET studies are, e.g., DASB, ketanserin, and WAY-100635.

[6][7] Some of these studies have considered methodogical issues such as the reproducibility of the method[8][9] or whether to use constant infusion[10] or bolus-infusion[11] delivery of altanserin.

Other studies have compared altanserin binding to subject variables such as age, personality trait and neuropsychiatric disorder.

The reaction of the terminal amino group with thiophosgene [463-71-8] leads to the corresponding isothiocyanate derivative, 4-fluorophenyl 1-(2-isothiocyanatoethyl)piperidin-4-yl ketone [84946-22-5] (3).

Upon reaction of this reactive intermediate with ethyl anthranilate [87-25-2] (4), the transient addition product might be expected to be initially formed (5').
