The influence of substitution at aromatic part of 1,2,3,4-tetrahydroisoquinoline on in vitro and in vivo 5-HT1A/5-HT2A receptor activities of its 1-adamantoyloaminoalkyl derivatives

Further structure-activity relationship (SAR) studies with the 1,2,3,4-tetrahydroisoquinoline (THIQ) class of 5-HT1A ligands led to the synthesis of new 1-adamantoyloaminoalkyl derivatives. The impact of substituent variations in the aromatic part of THIQ moiety on 5-HT1A and 5-HT2A receptor affinities, as well as in vivo functional properties of the investigated compounds were discussed. It was found that modification reduced the binding affinity for 5-HT1A receptors (in comparison with unsubstituted THIQ derivatives); however, the majority of new compounds still remained potent 5-HT1A ligands (Ki = 4.9-46 nM) and most of them showed features of partial agonists of postsynaptic 5-HT1A receptors. At the same time, their 5-HT2A receptor affinity was slightly increased (Ki = 40-1475 nM), which resulted in a loss of 5-HT2A/5-HT1A selectivity. 5-Br,8-OCH3 derivative – the most potent, mixed 5-HT1A/5-HT2A ligand – produced activation of presynaptic 5-HT1A receptors and showed properties of a 5-HT2A receptor antagonist.

Chemoselective Strategy for the Direct Formation of Tetrahydro-2,5-methanobenzo[c]azepines or Azetotetrahydroisoquinolines via Regio- and Stereoselective Reactions

The present study reports regio- and highly diastereoselective preparative methods for the synthesis of versatile alkaloid-type compounds from oxiranylmethyl tetrahydroisoquinolines. 2,5-Methanobenzo[c]azepines or azetidine-fused heterocycles were synthesized in tandem reactions depending on the absence or presence of a BF3 co-reagent. A high functional group tolerance has also been demonstrated. DFT calculations with an explicit solvent model confirmed the proposed reaction mechanisms and the role of kinetic controls on the stereochemical outcome of the reported new methods.

Facile synthesis of vicinal diamines via oxidation of N-phenyltetrahydroisoquinolines with DDQ

The oxidation of N-phenyltetrahydroisoquinolines occurs rapidly with DDQ. Under ambient conditions and in the presence of nitromethane, the corresponding beta-nitroamine derivatives are isolated in good to excellent yields. Variation in the electronic nature of the isoquinoline and the N-phenyl substituent showed that a broad range of substituents are tolerated, with electronic communication between the isoquinoline aromatic ring and the C1 carbon being stronger than with the N-aryl ring. Reduction of the beta-nitroamines to the corresponding novel chiral vicinal diamines are straightforward. Examination of the reaction by 1H NMR spectroscopy suggested that the reaction proceeds via an iminium ion, which then reacts with nitromethane upon work-up. This information was used to shorten the required reaction time.

These compounds bind in a DFG-in, alphaC-helix out conformation of B-Raf, which is a binding mode associated with significant kinase selectivity. Structure-activity relationship studies involved optimization of the ATP-cleft binding region of these molecules, and led to compound 23, an inhibitor with excellent enzyme/cell potency, and kinase selectivity.

Design, Synthesis, and Evaluation of Novel Ferulic Acid Derivatives as Multi-Target-Directed Ligands for the Treatment of Alzheimer’s Disease

A novel series of ferulic acid derivatives was designed and synthesized on the basis of the multi-target-directed ligands strategy for the treatment of Alzheimer’s disease (AD). In vitro results revealed that all the target compounds were highly effective and selective butyrylcholinesterase (BuChE) inhibitors. In particular, compound TM-10 showed the best BuChE inhibitory activity, with IC50 = 8.9 nM, and remarkable monoamine oxidase A and B inhibitory potency, with IC50 = 6.3 and 8.6 muM, respectively. TM-10 could inhibit (53.9%) and disaggregate (43.8%) self-induced amyloid-beta peptide (Abeta) aggregation. In addition, TM-10 exhibited potent antioxidant activity (ORAC = 0.52 equiv) and neuroprotective effect against Abeta1-42-mediated SH-SY5Y neurotoxicity, and it acted as an autophagic activator. TM-10 also showed good blood-brain barrier penetration. Furthermore, TM-10 exhibited a favorable dyskinesia recovery rate and response efficiency on an AlCl3-induced zebrafish AD model and a potent neuroprotective effect on Abeta1-40-induced zebrafish vascular injury. Further, in vivo assays demonstrated that TM-10 showed low acute toxicity, and the step-down passive avoidance test indicated that this compound could improve scopolamine-induced memory deficit in mice. Therefore, the present study displays evidence that TM-10 is a potent, multi-functional agent against AD and could be a promising lead candidate for anti-Alzheimer’s disease drug development.

Inhibition of Complex I by Isoquinoline Derivatives Structurally Related to 1-Methyl-4-Phenyl-1,2,3,6-Tetrahydropyridine (MPTP)

Mitochondrial respiratory failure secondary to complex I inhibition may contribute to the neurodegenerative process underlying nigral cell death in Parkinson’s disease (PD). Isoquinoline derivatives structurally related to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) or 1-methyl-4-phenylpyridinium (MPP+) may be inhibitors of complex I, and have been implicated in the cause of PD as endogenous neurotoxins. To determine the potency and structural requirements of isoquinoline derivatives to inhibit mitochondrial function, we examined the effects of 22 neutral and quaternary compounds from three classes of isoquinoline derivatives (11 isoquinolines, 2 dihydroisoquinolines, and 9 1,2,3,4-tetrahydroisoquinolines) and MPP+ on the enzymes of the respiratory chain in mitochondrial fragments from rat forebrain. With the exception of norsalsolinol and N,n-propylisoquinolinium, all compounds inhibited complex I in a time-independent, but concentration-dependent manner, with IC50s ranging from 0.36-22 mM. Several isoquinoline derivatives were more potent inhibitors of complex I than 1-methyl-4-phenylpyridinium ion (MPP+) (IC50 = 4.1 mM), the most active being N-methyl-6-methoxy-1,2,3,4-tetrahydroisoquinoline (IC50 = 0.36 mM) and 6-methoxy-1,2,3,4-tetrahydroisoquinoline (IC50 = 0.38 mM). 1,2,3,4-Tetrahydroisoquinoline was the least potent complex I inhibitor (IC50 ca. 22 mM). At 10 mM, only isoquinoline (23.1 percent), 6,7-dimethoxyisoquinoline (89.6 percent), and N-methylsalsolinol (34.8 percent) inhibited (P < 0.05) complex II-III, but none of the isoquinoline derivatives inhibited complex IV. There were no clear structure-activity relationships among the three classes of isoquinoline derivatives studied, but lipophilicity appears to be important for complex I inhibition. The effects of isoquinoline derivatives on mitochondrial function are similar to those of MPTP/MPP+, so respiratory inhibition may underlie their reported neurotoxicity.
