Application of the goldilocks effect to the design of potent and selective inhibitors of phenylethanolamine N-methyltransferase: Balancing pKa and steric effects in the optimization of 3-methyl-1,2,3,4- tetrahydroisoquinoline inhibitors by beta-fluorination

3-Methyl-1,2,3,4-tetrahydroisoquinolines (3-methyl-THIQs) are potent inhibitors of phenylethanolamine N-methyltransferase (PNMT), but are not selective due to significant affinity for the alpha2-adrenoceptor. Fluorination of the methyl group lowers the pKa of the THIQ amine from 9.53 (CH3) to 7.88 (CH2F), 6.42 (CHF2), and 4.88 (CF3). This decrease in pKa results in a reduction in affinity for the alpha2-adrenoceptor. However, increased fluorination also results in a reduction in PNMT inhibitory potency, apparently due to steric and electrostatic factors. Biochemical evaluation of a series of 3-fluoromethyl-THIQs and 3-trifluoromethyl-THIQs showed that the former were highly potent inhibitors of PNMT, but were often nonselective due to significant affinity for the alpha2-adrenoceptor, while the latter were devoid of alpha2-adrenoceptor affinity, but also lost potency at PNMT. 3-Difluoromethyl-7-substituted-THIQs have the proper balance of both steric and pKa properties and thus have enhanced selectivity versus the corresponding 3-fluoromethyl-7-substituted-THIQs and enhanced PNMT inhibitory potency versus the corresponding 3-trifluoromethyl-7-substituted- THIQs. Using the “Goldilocks Effect” analogy, the 3-fluoromethyl-THIQs are too potent (too hot) at the alpha2-adrenoceptor and the 3-trifluoromethyl-THIQs are not potent enough (too cold) at PNMT, but the 3-difluoromethyl-THIQs are just right. They are both potent inhibitors of PNMT and highly selective due to low affinity for the alpha2- adrenoceptor. This seems to be the first successful use of the beta-fluorination of aliphatic amines to impart selectivity to a pharmacological agent while maintaining potency at the site of interest.

Substituted 2-(1,2,3,4-tetrahydroisoquinoline)-butyl derivatives of azaspiro[4.5]decane-7,9-dione and phthalimide as new 5-HT1a and 5-HT2a receptor ligands

Two series of 2-butyl-8-azaspiro[5,4]decane-7,9-dione (a) and N-phthalimidobutyl (b) derivatives of 1,2,3,4-tetrahydroisoquinoline (THIQ) were synthesized. The impact of substituent variations in the aromatic part of the THIQ moiety on 5-HT1A and 5-HT2A receptor affinities, as well as in vivo functional properties of the investigated compounds are discussed. It was found that those modifications improved 5-HT2A receptor affinity, but also slightly reduced the binding affinity for 5-HT1A receptors (in comparison with the unsubstituted THIQ derivatives 3a and 3b). The most active compound (8-Br,5-OCH3-THIQ – 8a) showed features of a 5-HT1A (postsynaptic)/5-HT2A receptor antagonist. Additionally, all chloro derivatives with high and equal affinity for 5-HT1A receptors revealed different functional properties, i.e. an agonistic activity of presynaptic 5-HT1A receptors (4a) and a partial agonistic activity of postsynaptic 5-HT1A receptors (4a, 6a) or an antagonistic activity of postsynaptic ones (5a).

3-Hydroxyethyl- and 3-hydroxypropyl-7-substituted-tetrahydroisoquinolines (9, 10, 16, and 17) were synthesized and evaluated for their phenylethanolamine N-methyltransferase (PNMT) inhibitory potency and affinity for the alpha2-adrenoceptor. Although alpha2-adrenoceptor affinity decreased for these compounds, selectivity was not gained over the parent 3-hydroxymethyl compounds (1, 2) due to a loss in PNMT inhibitory potency.

Examination of the role of the acidic hydrogen in imparting selectivity of 7-(aminosulfonyl)-1,2,3,4-tetrahydroisoquinoline (SK and F 29661) toward inhibition of phenylethanolamine N-methyltransferase vs the alpha2-adrenoceptor

7-(Aminosulfonyl)-1,2,3,4-tetrahydroisoquinoline (SK and F 29661, 1) is a potent inhibitor of the enzyme phenylethanolamine N-methyltransferase (PNMT, EC 2.1.1.28). In contrast to other inhibitors of PNMT, it is also highly selective toward PNMT in comparison with its affinity toward the alpha2- adrenoceptor (PNMT K(i) = 0.55 muM, alpha2 K(i) = 100 muM, selectivity [alpha2 K(i)/PNMT K(i)] = 180). A diverse set of compounds was synthesized and evaluated to probe the role of the acidic hydrogen of the aminosulfonyl group of 1 in imparting this selectivity. Compounds were designed to investigate the effect on selectivity of the acidity of the NH group [the 7-N-methyl (compound 5) and 7-N-(p-chlorophenyl) (compound 4) derivatives of 1], the relative spatial position of the acidic hydrogen [7-(N- (methylsulfonyl)amino)-1,2,3,4-tetrahydroisoquinoline (6) and 7-((N- (methylsulfonyl)amino)methyl)-1,2,3,4-tetrahydroisoquinoline (8)], or the effect of the substitution of an acidic phenolic group for the aminosulfonyl moiety [1-(aminomethyl)-6-hydroxynaphthalene (28) and 8-hydroxy-1,2,3,4- tetrahydrobenz[h]isoquinoline (9)]. All of the compounds studied displayed lower affinity for PNMT than 1, and nine of the eleven compounds studied showed increased, rather than the desired decreased, affinity for the alpha2- adrenoceptor. Specifically, compound 4, in which the aminosulfonyl NH group is more acidic than that in 1, showed greatly reduced selectivity on account of increased alpha2-adrenoceptor affinity as compared to 1 (PNMT K(i) =- 2.6 muM, alpha2 K(i) = 6.3 muM, selectivity = 2.4). Compound 8, in which the acidic NH group is in the same region of space as that in 1, although the aminosulfonyl group is reversed with respect to the aromatic ring, showed poor PNMT affinity and modest alpha2-adrenoceptor affinity (PNMT K(i) = 330 muM, alpha2 K(i) = 18 muM, selectivity = 0.055). Compound 9, in which a phenolic group is in the same region of space as the acidic NH of 1, exhibited the best alpha2-adrenoceptor affinity of any of the compounds studied (PNMT K(i) = 0.98 muM, alpha2 K(i) = 0.078 muM, selectivity = 0.080). Results from this study suggest that the selectivity of 1 is not solely due to the presence of an acidic hydrogen on the 7-aminosulfonyl group of 1 but is likely also dependent on some other property (e.g. electron-withdrawing character) of the aminosulfonyl group.
