Synthesis and structure-activity relationships of novel selective factor Xa inhibitors with a tetrahydroisoquinoline ring

A series of novel 2,7-disubstituted tetrahydroisoquinoline derivatives were designed and synthesized. Among these derivatives, compounds 1 and 2 exhibited potent inhibitory activity against factor Xa (FXa) and good selectivity with respect to other serine proteases (thrombin, plasmin, and trypsin). In addition, compound 2 exhibited potent anti-FXa activity after intravenous and oral administration to cynomolgus monkeys, showed a dose-dependent antithrombotic effect at 0.1, 0.3, and 1 mg kg-1 h-1 in a rat model of venous thrombosis, and significantly reduced the size of brain infarction in a middle cerebral artery occlusion model at a dose of 0.1 mg kg-1 h-1. These results suggest that compound 2 (JTV-803) is likely to be useful as both a venous and arterial antithrombotic agent.

Synthesis, biochemical evaluation, and classical and three-dimensional quantitative structure-activity relationship studies of 7-substituted- 1,2,3,4-tetrahydroisoquinolines and their relative affinities toward phenylethanolamine N-methyltransferase and the alpha2-adrenoceptor

7-Substituted-1,2,3,4-tetrahydroisoquinolines (7-substituted-THIQs) are potent inhibitors of phenylethanolamine N-methyltransferase (PNMT, EC 2.1.1.28), the enzyme involved in the biosynthesis of epinephrine. Unfortunately, most of these compounds also exhibit strong affinity for the alpha2-adrenoceptor. To design a selective (PNMT vs alpha2-adrenoceptor affinity) inhibitor of PNMT, the steric and electrostatic factors responsible for PNMT inhibitory activity and alpha2-adrenoceptor affinity were investigated by evaluating a number of 7-substituted-THIQs. A classical quantitative structure-activity relationship (QSAR) study resulted in a three-parameter equation for PNMT (PNMT pK(i) = 0.599pi – 0.0725MR + 1.55sigma(m) + 5.80; n = 27, r = 0.885, s = 0.573) and a three-parameter equation for the alpha2- adrenoceptor (alpha2 pK(i) = 0.599pi – 0.0542MR – 0.951sigma(m) + 6.45; n = 27, r = 0.917, s = 0.397). These equations indicated that steric effects and lipophilicity play a similar role at either active site but that electronic effects play opposite roles at either active site. Two binding orientations for the THIQs were postulated such that lipophilic and hydrophilic 7- substituents would not occupy the same region of space at either binding site. Using these two binding orientations, based on the lipophilicity of the 7-substituent, comparative molecular field analysis (CoMFA) models were developed that showed that the steric and electrostatic interactions at both sites were similar to those previously elaborated in the QSAR analyses. Both the QSAR and the CoMFA analyses showed that the steric interactions are similar at the PNMT active site and at the alpha2-adrenoceptor and that the electrostatic interactions were different at the two sites. This difference in electrostatic interactions might be responsible for the selectivity of THIQs bearing a nonlipophilic electron-withdrawing group at the 7-position. These QSAR and CoMFA results will be useful in the design of potent and selective (PNMT vs alpha2-adrenoceptor affinity) inhibitors of PNMT.

Evaluation of antidepressant activity of 1-(7-methoxy-2-methyl-1,2,3,4-tetrahydro-isoquinolin-4-YL)-cyclohexanol, a beta-substituted phenylethylamine in mice

The beta-phenylethylamines are known to act as ligands for the trace amine receptors, a novel family of G-protein-coupled receptors. The trace amines are stored and released along with various neurotransmitter agents such as norepinephrine, serotonin, and dopamine and thus work as neuromodulator or neurotransmitter agents. Trace amines are known to play an important role in the pathophysiology of major depression. In our earlier study, we have demonstrated the synthesis of various beta-substituted phenylethylamine molecules hypothesized to be effective in various central nervous system disorders. The present study is an attempt to evaluate one of such molecules, 1-(7-methoxy-2-methyl-1,2,3,4-tetrahydro-isoquinolin-4-yl)-cyclohexanol, in animal models of depression. Various behavioral paradigms of despair such as forced swim and tail-suspension tests were used to assess the antidepressant-like activity. Further, an alteration in the levels of various neurotransmitters (norepinephrine, serotonin, and dopamine) in the mouse brain following 1-(7-methoxy-2-methyl-1,2,3,4-tetrahydro-isoquinolin-4-yl)-cyclohexanol administration was evaluated. The molecule (4-16. mg/kg., i.p.) dose-dependently inhibited the immobility period in mouse forced swim test, the effect comparable to venlafaxine. The ED50 values of 1-(7-methoxy-2-methyl-1,2,3,4-tetrahydro-isoquinolin-4-yl)-cyclohexanol and venlafaxine in mouse forced swim test were found to be 5.27 [4.38-6.35] mg/kg., i.p and 4.66 [3.48-6.25] mg/kg., i.p., respectively. Further, 1-(7-methoxy-2-methyl-1,2,3,4-tetrahydro-isoquinolin-4-yl)-cyclohexanol at 4-16. mg/kg., i.p. reversed the immobility period in mouse tail-suspension test. Additionally, the molecule at 8. mg/kg., i.p. reversed reserpine-induced behavioral despair in mouse forced swim test. When administered simultaneously, it (4 and 8. mg/kg., i.p) enhanced the antidepressant activity of sub-effective doses of imipramine (2. mg/kg., i.p.) or fluoxetine (2. mg/kg., i.p.) in the mouse forced swim test. Neurochemical analysis revealed that the molecule at 8. mg/kg., i.p. increased the levels of norepinephrine (21% increase) without affecting serotonin in the mouse brain. However, at higher dose (16. mg/kg., i.p.), it increased the levels of norepinephrine (13% increase), serotonin (37% increase), and dopamine (42% increase). The molecule enhanced the locomotor activity in mice only at higher doses. The molecule, unlike venlafaxine, which potentiated barbiturate-induced hypnosis, was devoid of any sedative activity. In conclusion, 1-(7-methoxy-2-methyl-1,2,3,4-tetrahydro-isoquinolin-4-yl)-cyclohexanol, possess antidepressant-like activity in animal models of depression by modulating the neurotransmitter levels in the brain. Such an activity might be due to the modulating action of this novel molecule on trace amine receptors. Such a molecule may be the future drugs of choice for the treatment of major depression.

Compound 48/80. Structure activity relations and poly THIQ, a new, more potent analog

Derivatives of p methoxyphenethylmethylamine were synthesized from which formaldehyde copolymers analogous to compound 48/80 were prepared. Measurement of the hypotensive activity of these analogs revealed that potency was not enhanced by changing the group in the para position, by varying the length of the alkyl group, or by altering the degree of methylation of the amine. However, when the ethylamine side chain was cyclized to form 7 methoxytetrahydroisoquinoline, the copolymer prepared from this derivative (poly THIQ) was seven times more potent than compound 48/80. The hypotensive action of poly THIQ was found to result from the liberation of histamine, as with compound 48/80.
