2-[(3-Methoxyphenylethyl)phenoxy]-Based ABCB1 Inhibitors: Effect of Different Basic Side-Chains on Their Biological Properties
摘要:
Recently, 2-[(3-methoxyphenylethyl)phenoxy]-moiety has been selected for the design and synthesis of new small ABCB1 inhibitors. In the present paper, this moiety has been linked through a spacer of 2-5 carbon atoms to the nitrogen of three different basic nuclei such as: (i) N-4-arylpiperazine, (ii) N-4-methylpiperazine, and (iii) 6,7-dimethoxytctrahydroisoquinoline. The results demonstrated that all the selected basic nuclei were well tolerated and that, globally, the best inhibitory activity for each series was obtained when the spacer between the 2-[(3-methoxyphenylethyl)phenoxy]moiety and the basic nucleus consisted of a four-carbon chain. Among the synthesized compounds, N-4-methylpiperazine- 10C (IC50 = 0.15 W) and tetrahydroisoquinoline-derivatives 11c (IC50 = 0.08 W) with the spacer n = 4 for both series, displayed the best potency to inhibit ABCB1 activity. Moreover, for each compound, the ABCB1 interacting mechanism has been evaluated by three combined biological assays. N-4-methylpiperazine- (10a-d) and tetrahydroisoquinoline-(11a-d) derivatives were Cyclosporin A-like ABCB1 nontransported substrates.
The limitations of established serotonin (5-hydroxytryptamine, 5-HT) and norepinephrine (NE) reuptake inhibitors necessitate the development of safer and more effective therapeutic agents. Based on the structures of 4-benzylpiperidine carboxamides and trazodone, arylpiperazine–benzylpiperidines with chemical scaffolds different from those of marketed drugs were designed, synthesized, and evaluated

Pharmaceutical composite compositions comprising tetrahydroindolones linked to arylpiperazines and derivatives thereof are disclosed. Specifically, composite compositions useful in treating anti-psychotic disorders are disclosed. The composite compositions disclosed herein can effectively ameliorate symptoms and treat psychotic disorders without causing a decrease in cognitive function. Generally, the composite compounds consist of two moieties, moiety A and B in which a tetrahydroindolone comprises a moiety A linked through a linker L to a moiety B, where B is an arylpiperazinyl moiety. The composite compound provides anti-psychotic actively by interaction with GABA, seratoninne and dopamine receptors. The composite molecules with the combined activities will provide treat psychiatric and neurological diseases without cognitive impairment.
Methods for treating emesis using compositions comprising a bicyclic ring moiety covalently linked to a substituted arylpiperazine moiety are disclosed.
