- Synthesis and biochemical evaluation of 3-fluoromethyl-1,2,3,4- tetrahydroisoquinolines as selective inhibitors of phenylethanolamine N- methyltransferase versus the α2-adrenoceptor
-
A series of 3-fluoromethyl-1,2,3,4-tetrahydroisoquinolines (3- fluoromethyl-THIQs) was proposed, and their phenylethanolamine N- methyltransferase (PNMT) and α2-adrenoceptor affinities were predicted through the use of comparative molecular field analysis (CoMFA) models. These compounds were synthesized and evaluated for affinity at PNMT and the α2- adrenoceptor. It was discovered that these compounds are some of the most selective inhibitors of PNMT versus the α2-adrenoceptor known. To determine the ability of these compounds to penetrate the blood-brain barrier (BBB), a series of THIQs possessing a variety of calculated partition coefficients (Clog P) were assayed using an in vitro BBB model. This study found a good correlation between lipophilicity (Clog P) and BBB permeability, which indicated that THIQs possessing Clog P values of at least 0.13-0.57 should have some penetration into the brain. Two compounds [3-fluoromethyl-7-N-(4- chlorophenyl)aminosulfonyl-THIQ (18) and 3-fluoromethyl-7-cyano-THIQ (20)] possess calculated partition coefficients greater than 0.57 and display selectivities (α2-adrenoceptor K/PNMT K1) greater than 200 and thus represent promising leads in the development of highly selective inhibitors of PNMT with the ability to penetrate the BBB.
