Cytotoxicity of 1-amino-4-phenyl-1,2,3,6-tetrahydropyridine and 1- amino-4-phenylpyridinium ion, 1-amino analogues of MPTP and MPP+, to clonal pheochromocytoma PC12 cells

1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induces parkinsonism in humans after its oxidation into 1-methyl-4-phenylpyridinium ion (MPP+) by type B monoamine oxidase. The 1-amino analogues of MPTP and MPP+, 1-amino- 4-phenyl-1,2,3,6-tetrahydropyridine (APTP) and 1-amino-4-phenylpyridinium ion (APP+), were synthesized, and their cytotoxicity to clonal pheochromocytoma PC12 cells was examined using a tetrazolium formazan assay. After incubation for 48 and 72 h, both APP+ and APTP were found to be cytotoxic to PC12 cells, whereas with the N-methyl analogues, only MPP+, but not MPTP, was cytotoxic. The cytotoxicity of APTP increased with incubation time and equaled that of MPP+ after 72 h. It was found that APTP was oxidized to APP+ by type A monoamine oxidase in PC12 cells, suggesting that APP+ itself may damage the cells. In addition to APTP and APP+, N-amino analogues of N- methylisoquinolines and related derivatives were also synthesized and examined for their cytotoxicity to PC12 cells.

Decarboxylative C?C and C?N Bond Formation by Ligand-Accelerated Iron Photocatalysis

The photoexcited state lifetimes of iron complexes are typically much shorter than those of iridium and ruthenium complexes. For that reason, iron complexes find less application in photochemical organic synthesis. Through iron photocatalysis, a mild and effective protocol for decarboxylative C?C and C?N bond formation has been achieved. The carboxylic acids readily undergo radical decarboxylation in the presence of Fe2(SO4)3 and di-(2-picolyl)amine under visible light irradiation. The resulting alkyl radicals then react with Michael acceptors or azodicarboxylates to furnish the adducts.

Cross-dehydrogenative coupling reaction using copper oxide impregnated on magnetite in deep eutectic solvents

The synthesis of different tetrahydroisoquinolines using choline chlorideethylene glycol as a deep eutectic solvent (DES) and copper(ii) oxide impregnated on magnetite as a catalyst has been accomplished successfully. The copper catalyst amount is the lowest loading ever reported. The presence of DES showed to be essential since the reaction in the absence of this medium did not proceed. A direct proportional relationship was found between the conductivity of DES medium and the yield obtained. The DES and the catalyst could be reused up to ten times without any detrimental effect on the yield of the reaction, with the aerobic conditions making the protocol highly sustainable, where the only waste is water.

Visible-light induced enhancement in the multi-catalytic activity of sulfated carbon dots for aerobic carbon-carbon bond formation

The development of carbonaceous materials as metal-free catalysts integrating different types of catalysis in a single system represents a significant advance in cascade/tandem organic synthesis. Zero-dimensional carbon dots with tuneable optical properties and easily modifiable surface functionalities can be harnessed as a carbocatalyst for merging photooxidation and acid-catalyzed reactions in one pot. Herein, we explore carbon dots decorated with hydrogen sulfate groups as a photocatalyst for the dehydrogenative cross-coupling of xanthenes with ketones, arenes and 1,3-dicarbonyl compounds that showed high efficiency and selectivity under visible-light irradiation. The sulphated carbon dots demonstrate dual catalytic properties, wherein they induced the rapid photooxidation of xanthenes in the presence of molecular oxygen to form a hydroperoxy intermediate followed by coupling of nucleophiles catalysed by the acidic surface functional groups. The methodology represents an operationally simple pathway for the generation of C-C coupling products in a short reaction time with wide substrate scopes under mild conditions. The catalyst is easily separable and can be reused over multiple cycles with good efficiency.

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 3340-78-1 is helpful to your research. Reference of 3340-78-1

Flexibility of shape-persistent molecular building blocks composed of p-phenylene and ethynylene units

Ethynylene and rho-phenylene are frequently employed constitutional units in constructing the backbone of nanoscopic molecules with specific shape and mechanical or electronic function. How well these properties are defined depends on the flexibility of the backbone, which can be characterized via the end-to-end distance distribution. This distribution is accessible by pulse electron paramagnetic resonance (EPR) distance measurements between spin labels that are attached at the backbone. Four sets of oligomers with different sequences of rho-phenylene and ethynylene units and different spin labels were prepared using polar tagging as a tool for simple isolation of the targeted compounds. By variation of backbone length, of the sequence of rho-phenylene and ethynylene units, and of the spin labels a consistent coarse-grained model for backbone flexibility of oligo(rho-phenyleneethynylene)s and oligo(rho-phenylenebutadiynylene)s is obtained. The relation of this harmonic segmented chain model to the worm-like chain model for shape-persistent polymers and to atomistic molecular dynamics simulations is discussed. Oligo(rho-phenylene butadiynylene)s are found to be more flexible than oligo(rho-phenyleneethynylene)s, but only slightly so. The end-to-end distance distribution measured in a glassy state of the solvent at a temperature of 50 K is found to depend on the glass transition temperature of the solvent. In the range between 91 and 373 K this dependence is in quantitative agreement with expectations for flexibility due to harmonic bending. For the persistence lengths at 298 K our data predict values of (13.8 ± 1.5) nm for poly(rho-phenyleneethynylene)s and of (11.8 ± 1.5) nm for poly(rho-phenylenebutadiynylene)s.
