Application of 1745-07-9

The authors have prepared a series of tetrahydro-beta-carbolines (THbetaC), beta-carbolines (beta-C), and other nitrogen heterocycles and evaluated them in vitro with respect to their ability to bind to benzodiazepine receptors. The fully aromatic beta-C’s were more potent than their corresponding THbetaC derivatives. When substituents possessing a carbonyl (CO2Me, COCH3, CHO) were introduced at the beta-C 3-position the in vitro potency was augmented. Alcohol substituents (CH2OH, CHOHCH3) demonstrated decreased in vitro potency. The importance of the carbonyl moiety was further demonstrated when beta-carboline-3-carboxylic acid was shown to bind tighter to benzodiazepine receptors at lower pH. A lower pH increases the concentration of the acid and decreases the concentration of the anion. 3-(Hydroxymethyl)-beta-carboline, 3-formyl-beta-carboline and 3-acetyl-beta-carboline were benzodiazepine antagonists in vivo. Methyl isoquinoline-3-carboxylate also had in vitro activity. The same structure-activity relationships seen in beta-C’s were also observed for isoquinolines.

Overexpression of the ATP-binding cassette (ABC) transport proteins, like ABCB1, commonly referred to as P-glycoprotein (P-gp), initiates active efflux of a broad spectrum of unrelated chemotherapeutic drugs in structure and function, leading to chemotherapy failure. A series of 2-((pyridin-4-ylmethyl)amino)nicotinamide derivatives as potent reversal agents against P-glycoprotein-mediated multidrug resistance (MDR) were designed and synthesized. The majority of target compounds displayed great reversal potency, especially 9n. In-depth studies demonstrated 9n has high potency (EC50 = 119.6 ± 6.9 nM), low cytotoxicity, and long duration (>24 h) in reversing adriamycin (ADM) resistance in K562/A02 cells. 9n also improved the effects of other cytotoxic agents related to MDR, increased accumulation of ADM, interrupted P-gp-mediated Rh123 efflux function, and suppressed P-gp ATPase activity in K562/A02 MDR cells. The Western blot analysis indicated that the MDR reversal by 9n was not due to a decrease in protein expression. Besides, the effect of CYP3A4 was not influenced by 9n, avoiding the toxicity caused by drug interactions. The study yielded 9n with superior properties compared to the classical inhibitor verapamil (VRP) and leading compound apatinib.

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.

Novel 1,2,3,4-tetrahydroisoquinoline derivatives bearing directly a cyclic amine at the 2-position were prepared and examined for their bradycardic activities in isolated right atria and in anesthetized rats. The structure-activity relationships (SAR) study revealed that the 2-(3-piperidyl)-1,2,3,4-tetrahydroisoquinoline skeleton is essential for the appearance of potent in vitro activity, and that the presence of at least one methoxy group at the 6- or 7-position of the 1,2,3,4-tetrahydroisoquinoline ring is important to exert potent in vitro activity. In vivo tests of selected compounds demonstrated that 2-(1-benzyl-3-piperidyl)-6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline (6c) exhibited potent bradycardic activity with negligible influence on mean blood pressure in rats, although its potency is a half of that of Zatebradine.

TRPV1 receptor is an important analgesia target. Its antagonists are expected to prevent pain perception by blocking the receptor directly. In this letter, eight dihydroisoquinoline-2(1H)-carbothioamide derivatives were designed and synthesized as TRPV1 antagonists. The benzene ring was modified with different substitutional groups. Preliminary biological tests suggested that the new compounds exhibited TRPV1 antagonist activity and different analgesia effects, some of which were promising as analgesia drugs.

S-Adenosyl-L-methionine (SAM): coclaurine N-methyltransferase (CNMT), which catalyzes the transfer of a methyl group from S-adenosyl-L-methionine to the amino group of the tetrahydrobenzylisoquinoline alkaloid coclaurine, was purified 340-fold from Coptis japonica cells in 1% yield to give an almost homogeneous protein. The purified enzyme, which occurred as a homotetramer with a native Mr of 160 kDa (gel-filtration chromatography) and a subunit Mr of 45 kDa (SDS-polyacrylamide gel electrophoresis), had an optimum pH of 7.0 and a pI of 4.2. Whereas (R)-coclaurine was the best substrate for enzyme activity, Coptis CNMT had broad substrate specificity and no stereospecificity; CNMT methylated norlaudanosoline, 6,7-dimethoxyl-1,2,3,4-tetrahydroisoquinoline and 1-methyl-6,7-dihydroxy-1,2,3,4,-tetrahydroisoquinoline. The enzyme did not require any metal ion. p-Chloromercuribenzoate and iodoacetamide did not inhibit CNMT activity, but the addition of Co2+, Cu2+ or Mn2+ at 5 mM severely inhibited such activity by 75, 47 and 57%, respectively. The substrate-saturation kinetics of CNMT for norreticuline and SAM were of the typical Michaelis-Menten-type with respective Km values of 0.38 and 0.65 mM.

The development of small molecules as P-gp modulating agents and SAR studies on these ligands represented the aim of the present work. A series of 6,7-dimethoxytetrahydroisoquinoline derivatives was prepared and their ability to inhibit P-gp activity has been evaluated. The basic nucleus of these compounds, common to the best P-gp inhibitors such as Tariquidar and Elacridar, has been functionalized with no-basic moiety from our studied sigma receptor ligands displaying potent P-gp inhibition. The best results were obtained for compounds 3c and 3a (EC50 = 1.64 and 4.86 muM, respectively) and these results were remarkable because Elacridar showed in the same biological evaluation similar inhibitory activity (EC50 = 2 muM). SAR studies displayed that the removal of double bond on the spacer or its shifting into tetraline ring decreased the P-gp inhibiting activity. Moreover, the P-gp inhibition mechanism of tested compounds was investigated by three selected biological experiments. The results displayed that only compound 3c was P-gp inhibitor as Elacridar, while compound 3a and reference compounds Cyclosporin A and Verapamil modulated P-gp activity saturating the efflux pump as substrates. Flow cytometry studies carried out in Doxorubicin resistant breast cancer cell line (MCF7/Adr) confirmed that compound 3c increased Doxorubicin cell accumulation 5.7-fold. In addition, in MCF7/Adr, antiproliferative effect of 5 muM Doxorubicin shifted from 5% to 95% when co-administered with compound 3c (20 muM). The present study suggested a new class of small molecules displaying P-gp inhibitor activity differing from reference compounds Elacridar and Tariquidar for a simplified, and in the meantime, efficacious no-basic moiety.
