Synthesis of 2-aryl-3,4-dihydroisoquinolin-2-ium bromides and their in Vitro acaricidal activity against Psoroptes cuniculi

By employing sanguinarine, a natural active quaternary isoquinoline alkaloid, as a model molecule, a series of structurally simple quaternary 2-aryl-3,4-dihydroisoquinolin-2-ium compounds were designed and synthesized and evaluated for in vitro acaricidal activity against P. cuniculi. A new approach towards the title compounds was developed with isochroman as starting material. The results showed that 22 of 24 tested compounds displayed the activity in varying degrees at 0.4 mg/mL. Fourteen compounds were significantly more effective than ivermectin, a standard acaricide, and 6-methoxy dihydrosanguinarine, a derivative of sanguinarine (p<0.05). And their comprehensive relative activity was 1.4 to 16.5 times than that of ivermectin and 1.5 to 18.8 times than that of 6-methoxy dihydrosanguinarine. The structure-activity relationship indicated that the introduction of a substituent to N-benzene ring, especially halogen atom and trifluoromethyl group, led to great improvement of the activity. The position of fluorine atom, methyl group and hydroxyl group made very significant effects on the activity. It was concluded that 2-aryl-3,4-dihydroisoquinolin- 2-iums are very promising candidates for the development of new isoquinoline acaricidal agents. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 3340-78-1, help many people in the next few years.HPLC of Formula: C15H15N

Glutamic acid analogues as potent dipeptidyl peptidase IV and 8 inhibitors

To find potent and selective inhibitors of dipeptidyl peptidase IV (DPP-IV), we synthesized a series of 2-cyanopyrrolidine with P2-site 4-substituted glutamic acid derivatives and tested their activities against DPP-IV, DPP8, and DPP-II. Analogues that incorporated a bulky substituent at the first carbon position of benzylamine or isoquinoline showed over 30-fold selectivity for DPP-IV over both DPP8 and DPP-II. From structure-activity relationship studies, we speculate that the S2 site of DPP8 might be similar to that of DPP-IV, while DPP-IV inhibitor with N-substituted glycine in the P2 site and/or with a moiety involving in hydrophobic interaction with the side chain of Phe357 might provide a better selectivity for DPP-IV over DPP8.

Cross dehydrogenative coupling of: N -aryltetrahydroisoquinolines (sp3 C-H) with indoles (sp2 C-H) using a heterogeneous mesoporous manganese oxide catalyst

We disclose a novel, heterogeneous catalytic approach for selective coupling of C1 of N-aryltetrahydroisoquinolines with C3 of indoles in the presence of mesoporous manganese oxides. Our work involves a detailed mechanistic investigation of the reaction on the catalyst surface, backed by DFT computational studies, to understand the superior catalytic activity of manganese oxides.

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.

Search for New Alkaloids in Pachycereus weberi by Tandem Mass Spectrometry

Twenty new alkaloids, of which 13 are new natural products, have been discovered in Pachycereus weberi by tandem mass spectrometry using a mass-analyzed ion kinetic energy spectrometer.These observations have been confirmed by chromatography and, in many cases, by simple synthetic interconversions from known alkaloids.Particularly significant is the discovery of several alkaloids having the same molecular formula.Isomer distinctions such as these, which are difficult to make on pure compounds by mass spectrometry, were made by utilizing daughter spectra recorded succesively during the evaporation of the material from the probe and/or from spectra recorded on different types of plant extracts.This study suggests that many natural materials may contain trace amounts of compounds of potential biomedical or synthetic interest and, in particular, that the number of known alkaloids might be greatly increased by experiments of this type.

TiO2-Supported Re as a General and Chemoselective Heterogeneous Catalyst for Hydrogenation of Carboxylic Acids to Alcohols

TiO2-supported Re, Re/TiO2, was found to promote selective hydrogenation of carboxylic acids having aromatic and aliphatic moieties to the corresponding alcohols. Re/TiO2showed superior results compared to other transition-metal-loaded TiO2and supported Re catalysts for selective hydrogenation of 3-phenylpropionic acid. 3-phenylpropanol was produced in 97 % yield under mild conditions (5 MPa H2at 140 C). Contrary to typical heterogeneous catalysts, Re/TiO2does not lead to the formation of dearomatized byproducts. The catalyst is recyclable and shows a wide substrate scope in the synthesis of alcohols (22 examples; up to 97 % isolated yield).

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 166591-85-1 is helpful to your research. Electric Literature of 166591-85-1

Discovery of a small-molecule inhibitor and cellular probe of Keap1-Nrf2 protein-protein interaction

A high-throughput screen (HTS) of the MLPCN library using a homogenous fluorescence polarization assay identified a small molecule as a first-in-class direct inhibitor of Keap1-Nrf2 protein-protein interaction. The HTS hit has three chiral centers; a combination of flash and chiral chromatographic separation demonstrated that Keap1-binding activity resides predominantly in one stereoisomer (SRS)-5 designated as ML334 (LH601A), which is at least 100¡Á more potent than the other stereoisomers. The stereochemistry of the four cis isomers was assigned using X-ray crystallography and confirmed using stereospecific synthesis. (SRS)-5 is functionally active in both an ARE gene reporter assay and an Nrf2 nuclear translocation assay. The stereospecific nature of binding between (SRS)-5 and Keap1 as well as the preliminary but tractable structure-activity relationships support its use as a lead for our ongoing optimization.
