Acetic Acid Promoted Redox Annulations with Dual C-H Functionalization

Amines such as 1,2,3,4-tetrahydroisoquinoline undergo redox-neutral annulations with 2-alkylquinoline-3-carbaldehydes as well as the corresponding 4-alkyl isomers and pyridine analogues. These processes involve dual C-H bond functionalization. Acetic acid is used as a cosolvent and acts as the sole promoter of these transformations.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. HPLC of Formula: C11H15NO2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1745-07-9, in my other articles.

Design, synthesis, and preliminary activity evaluation of novel pyrimidine derivatives as acid pump antagonists

Acid-related diseases of the upper gastrointestinal tract, especially gastroesophageal reflux disease (GERD), remain a widespread problem worldwide. In this paper, we reported the design, synthesis, and preliminary gastric antisecretory activity evaluation of novel pyrimidine derivatives as acid pump antagonists. The gastric antisecretory activity assay results showed that all compounds displayed potent gastric antisecretory activity when gastric secretion was stimulated by histamine. The most potent compound 5g exhibited even similar gastric antisecretory activity compared with the control revaprazan, and the relative inhibition rate was 93.0%, which was worthy of further investigation.

Multifunctional thiosemicarbazones and deconstructed analogues as a strategy to study the involvement of metal chelation, Sigma-2 (sigma2) receptor and P-gp protein in the cytotoxic action: In vitro and in vivo activity in pancreatic tumors

The aggressiveness of pancreatic cancer urgently requires more efficient treatment options. Because the sigma-2 (sigma2) receptor was recently proposed as a promising target for pancreatic cancer therapy, we explored our previously developed multifunctional thiosemicarbazones, designed to synergistically impair cell energy levels, by targeting sigma2 and P-gp proteins and chelating Iron. A deconstruction approach was herein applied by removing one function at a time from the potent multifunctional thiosemicarbazones 1 and 2, to investigate the contribution to cytotoxicity of each target involved. The results from in vitro (panel of pancreatic tumor cells) and in vivo experiments (C57BL/6 bearing KP02 tumor), suggest that while the multifunctional activity was not required for the antitumor activity of these thiosemicarbazones, sigma2-targeting appeared to allow alternative tumor cell death mechanisms, leading to potent and less toxic off-targets toxicities compared to other thiosemicarbazones devoid of sigma2-targeting.

Radical alkylation of C(sp3)-H bonds with diacyl peroxides under catalyst-free conditions

Herein, we describe a protocol for alkylation reactions of C(sp3)-H bonds with diacyl peroxides by means of a process involving cross-coupling between an alkyl radical and an alpha-Aminoalkyl radical. The mild, catalyst-And additive-free conditions make this protocol superior to previously reported C(sp3)-H alkylation strategies. The protocol was applied to 1,2,3,4-Tetrahydroisoquinolines and a tetrahydro-beta-carboline derivative and could be carried out on a gram scale, indicating its utility for the alkylation of late-stage synthetic intermediates.

11C- and 18F-Labeled Radioligands for P-Glycoprotein Imaging by Positron Emission Tomography

P-Glycoprotein (P-gp) is an efflux transporter widely expressed at the human blood-brain barrier. It is involved in xenobiotics efflux and in onset and progression of neurodegenerative disorders. For these reasons, there is great interest in the assessment of P-gp expression and function by noninvasive techniques such as positron emission tomography (PET). Three radiolabeled aryloxazole derivatives: 2-[2-(2-methyl-(11C)-5-methoxyphenyl)oxazol-4-ylmethyl]-6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline ([11C]-5); 2-[2-(2-fluoromethyl-(18F)-5-methoxyphenyl)oxazol-4-ylmethyl]-6,7-dimethoxy-1,2,3,4-tetra-hydroisoquinoline ([18F]-6); and 2-[2-(2-fluoroethyl-(18F)-5-methoxyphenyl)oxazol-4-ylmethyl]-6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline ([18F]-7), were tested in several invitro biological assays to assess the effect of the aryl substituent in terms of potency and mechanism of action toward P-gp. Methyl derivative [11C]-5 is a potent P-gp substrate, whereas the corresponding fluoroethyl derivative [18F]-7 is a P-gp inhibitor. Fluoromethyl compound [18F]-6 is classified as a non-transported P-gp substrate, because its efflux increases after cyclosporineA modulation. These studies revealed a promising substrate and inhibitor, [11C]-5 and [18F]-7, respectively, for invivo imaging of P-gp by using PET.

Orthogonal sp3 C1-H and N-H Bond Functionalization of 1,2,3,4-Tetrahydroisoquinolines via the Ugi Four-Component Reaction

A new protocol for orthogonal sp3 C1-H and N-H bond functionalization of 1,2,3,4-tetrahydroisoquinolines has been established via the Ugi four-component reaction with aldehydes, isonitriles, and carboxylic acids. It was revealed that only the N-H bond could be functionalized when the reaction was performed in acetonitrile at room temperature; however, when the reaction was carried out in toluene at 80 C, redox-neutral sp3 C1-H bond functionalization of 1,2,3,4-tetrahydroisoquinolines was achieved. Differing from the common role of carboxylic acid as a promoter in redox-neutral amine alpha-functionalization, the carboxylic acid employed herein is also a reactant. The orthogonal process is compatible with various substrates and provides an appealing access to a library of structurally diverse 1,2,3,4-tetrahydroisoquinolines.

Selective dopaminergic neurotoxicity of isoquinoline derivatives related to Parkinson’s disease: Studies using heterologous expression systems of the dopamine transporter

Endogenous isoquinoline (IQ) derivatives structurally related to the selective dopaminergic neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) and its active metabolite 1-methyl-4-phenylpyridine (MPP+) may contribute to dopaminergic neurodegeneration in Parkinson’s disease. We addressed the importance of the DAT molecule for selective dopaminergic toxicity by testing the differential cytotoxicity of 22 neutral and quaternary compounds from three classes of isoquinoline derivatives (3, IQs; 4,3,4-dihydroisoquinolines and 15, 1,2,3,4-tetrahydroisoquinolines) as well as MPP+ in non-neuronal and neuronal heterologous expression systems of the DAT gene (human embryonic kidney HEK-293 and mouse neuroblastoma Neuro-2A cells, respectively). Cell death was estimated using the MTT assay and the Trypan blue exclusion method. Nine isoquinolines and MPP+ showed general cytotoxicity in both parental cell lines after 72 hr with half-maximal toxic concentrations (TC50 values) in the micromolar range. The rank order of toxic potency was: papaverine > salsolinol=tetrahydropapaveroline=1-benzyl-TIQ=norsalsolinol > tetrahydropapaverine > 2[N]-methyl-salsolinol > 2[N]-methyl-norsalsolinol > 2[N]-Me-IQ+=MPP+. Besides MPP+, only the 2[N]-methylated compounds 2[N]-methyl-IQ+, 2[N]-methyl-norsalsolinol and 2[N]-methyl-salsolinol showed enhanced cytotoxicity in both DAT expressing cell lines with 2- to 14-fold reduction of TC50 values compared to parental cell lines. The rank order of selectivity in both cell systems was: MPP+ ? 2[N]-Me-IQ+ > 2[N]-methyl-norsalsolinol=2[N]-methyl-salsolinol. Our results suggest that 2[N]-methylated isoquinoline derivatives structurally related to MPTP/MPP+ are selectively toxic to dopaminergic cells via uptake by the DAT, and therefore may play a role in the pathogenesis of Parkinson’s disease.

Visible-Light-Mediated Photocatalytic Aerobic Dehydrogenation of N-heterocycles by Surface-Grafted TiO2 and 4-amino-TEMPO

Herein, the visible-light-induced dehydrogenation of N-heterocycles such as tetrahydroquinolines, tetrahydroisoquinolines, and indolines in O2-containing suspensions of a commercially available titanium dioxide photocatalyst yielding the corresponding heteroarenes is presented. 4-Amino-2,2,6,6-tetramethylpipiridinyloxyl (4-amino-TEMPO) was found to exhibit a beneficial role, as it increased the yield and improved the selectivity of the dehydrogenation reaction. Both the selectivity and the yield are further enhanced by grafting 0.1 wt % of Ni(II) ions onto the TiO2 surface. It is proposed that the basic reactant adsorbs at Lewis acid sites present at the TiO2 surface. The dehydrogenation reaction is initiated by visible-light excitation of the resulting surface complex and a subsequent single-electron transfer from the excited N-heterocycle via the conduction band of TiO2 to O2. Ni(II) ions possibly serve as an electron transfer bridge between the conduction band of TiO2 and O2, while the TEMPO derivative is assumed to act as a selective redox mediator involved in reactions of the generated reactive oxygen species.
