Allosteric potencies of the most potent compounds in inhibiting the dissociation of [³H]S-1 from hSERT.

Compound	Allosteric Potencya (in µM)^a
S-1	4.6[4.2;5.0]^b
20	3.6[3.4;3.8]
25	4.7[3.8;5.7]
42	5.3[3.0;9.5]
51	4.9[4.4;5.5]
53	3.0[2.2;4.0]
55	5.8[4.8;7.1]
(+)62	3.4[2.4;4.8]

The allosteric potencies are the IC₅₀ values obtained from non-linear regression analysis of data from [³H]S-1 dissociation experiments in the presence of increasing concentrations of the indicated compounds. The dissociation rate constants (k_[cmpd]) at different compound concentrations were calculated by linear regression and expressed relative to the dissociation rate constant without the presence of unlabeled ligand (k_buffer). The allosteric potency is determined as the IC₅₀ value of the drug concentration (log[cmpd]) that impairs the dissociation rate by 50% compared with dissociation in buffer (k_[cmpd]/k_buffer) and are shown as mean values calculated from means of pIC₅₀ and the SE interval from the pIC₅₀ ±S.E of 3–8 experiments performed in triplicate.
