Purpose of review Machado-Joseph disease (MJD), also known as spinocerebellar ataxia type 3 (SCA3), is a fatal, dominantly inherited, neurodegenerative disease caused by expansion of a CAG repeat in the coding region of theATXN3gene. No disease-modifying treatment is yet available for MJD/SCA3. This review discusses recently developed therapeutic strategies that hold promise as future effective treatments for this incurable disease. Recent findings As a result of the exploration of multiple therapeutic approaches over the last decade, the MJD/SCA3 field is finally starting to see options for disease-modifying treatments for this disease come into view on the horizon. Recently developed strategies include DNA-targeted and RNA-targeted therapies, and approaches targeting protein quality control pathways and cellular homeostasis. While still in preclinical testing stages, antisense oligonucleotides, short hairpin RNAs and citalopram all show promise to reaching testing in clinical trials for MJD/SCA3. Two pharmacological approaches in early stages of development, the slipped-CAG DNA binding compound naphthyridine-azaquinolone and autophagosome-tethering compounds, also show potential therapeutic capacity for MJD/SCA3. Overall, a handful of therapeutic options are currently showing potential as future successful treatments for fatal MJD/SCA3.

Grafting of -aminobutyric acid on the superparamagnetic -Fe2O3@SiO2 nanoparticles afforded -Fe2O3@SiO2–aminobutyric acid as a novel heterogeneous nanocatalyst, which was characterized by X-ray diffraction, Fourier transform-infrared spectroscopy, vibrating sample magnetometry, field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, and thermal analysis. In this research, we report a convenient and one-pot efficient direct protocol for the pseudo four-component preparation of chromeno[4,3,2-de][1,6]naphthyridine derivatives via cascade condensation reaction of malononitrile, 2,4-dihydroxyacetophenone with various aromatic aldehydes in the presence of the catalytic amount of the -Fe2O3@SiO2–aminobutyric acid under green conditions in aqueous media. This procedure offers several advantages such as: very easy reaction conditions, simple work-up, or purification, excellent yields, high purity of the desired product, atom economy, and short reaction times. The superparamagnetic nanocatalyst is magnetically separable and kept stability after recycling for at least five consecutive runs without detectable activity loss. [GRAPHICS] .

In the reaction of 4-chlorocoumarin-3-carbaldehyde with malononitrile in the presence of piperidine a crystalline piperidinium salt of a novel tetracyclic chromeno[4,3,2-de]-1,6-naphthyridine-2-carboxylic acid was isolated instead of the expected product of the tert-amino effect. The structure of this piperidinium salt and its corresponding acidic form was characterized through spectral methods (IR, NMR, MS) and elemental analysis. In addition, the structure was established by means of X-ray crystallographic analysis. A theoretical multistep mechanism for this one-pot synthesis is discussed.

New Advances in Chemical Research in 2021. Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 91-76-9, Name is 2,4-Diamino-6-phenyl-1,3,5-triazine, molecular formula is , belongs to naphthyridine compound. In a document, author is Arslan, Barn Seckin, Formula: https://www.ambeed.com/products/91-76-9.html.

A new series of D-pi-A organic dyes bearing fused dibenzo[b,h] [1,6]naphthyridine as the conjugated pi-bridge, a cyanoacrylic acid moiety as the electron acceptor/anchoring group and different electron donor groups such as trimethoxy (5a), methoxy (5b) and dimethylamino (5c), were designed and synthesized for dye-sensitized solar cells (DSSCs), for the first time. The effect of donor groups on the performance of the DSSCs was systematically investigated using optical, electrochemical, theoretical and photovoltaic methods. Compared to dyes 5a and 5b, 5c showed a broader and more red-shifted absorption spectrum due to stronger electron donating ability of dimethylamino moiety, which is beneficial for absorbing more photons and thus generating high photocurrent, As a result, the DSSC fabricated with dye 5c has the highest power conversion efficiency of 5.02% (similar to 60% relative to N719-based standard cell), which is greater than those obtained by 5a and 5b-sensitized solar cells (3.22% and 2.13%, respectively) under standard air mass 1.5 global (AM 1.5 G) conditions. The improved photovoltaic performance mainly came from better photocurrent, as also confirmed by IPCE measurements. These results suggest that dibenzo[b,h] [1,6]naphthyridine pi-bridge bearing a strong electron donor group is a promising candidate to construct effective D-pi-A organic dyes for DSSCs.

Ferrocenylamido-naphthyridine conjugates [{(5,7-dimethyl-1,8-naphthyridin-2-yl)amino} carbonyl] ferrocene (L-1) and 1,1′-bis[{(5,7-dimethyl-1,8-naphthyridin-2-yl) amino} carbonyl] ferrocene (L-2) have been synthesized. Reaction of L-1 with [Cu(CH3CN)(6)][ClO4](2) affords [Cu(L-1)(2)][ClO4](2) (1) demonstrating tridentate coordination of the ligand utilizing naphthyridine (NP) nitrogens and carbonyl oxygen. Hydroxo-bridged neutral dirhenium(I) compound [K subset of {{Re(CO)(3)}(2)(mu-OH)(Fc(CONHNP)(CO (N) over bar NP))(2)}] (2) is reported in which the amido-NP arm of L-2 chelates a Re-I, and a K+ ion is encapsulated in a six-coordinate environment rendered by four NP nitrogens and two carbonyl oxygens involving all four arms of two L-2 ligands. Selective and reversible binding of K+ ion by the organometallic host has been recognized from electrochemical and fluorescence experiments. Partial hydrolysis of L-2 has provided a neutral metallamacrocycle [{Re(CO)(3)}(2){Fc(CO2)(CONHNP)}(2)] (3) consisting of alternate Fc and Re(CO)(3) units linked by carboxylate and amide-NP bridges. The rotational freedom of the ferrocenyl rings, the flexibility of the amide linker and the multi-site coordination of the ligands are demonstrated in the molecular structures of compounds 1-3.
