In many repeat diseases, such as Huntington’s disease (HD), ongoing repeat expansions in affected tissues contribute to disease onset, progression and severity. Inducing contractions of expanded repeats by exogenous agents is not yet possible. Traditional approaches would target proteins driving repeat mutations. Here we report a compound, naphthyridine-azaquinolone (NA), that specifically binds slipped-CAG DNA intermediates of expansion mutations, a previously unsuspected target. NA efficiently induces repeat contractions in HD patient cells as well as en masse contractions in medium spiny neurons of HD mouse striatum. Contractions are specific for the expanded allele, independently of DNA replication, require transcription across the coding CTG strand and arise by blocking repair of CAG slip-outs. NA-induced contractions depend on active expansions driven by MutS beta. NA injections in HD mouse striatum reduce mutant HTT protein aggregates, a biomarker of HD pathogenesis and severity. Repeat-structure-specific DNA ligands are a novel avenue to contract expanded repeats. Naphthyridine-azaquinolone specifically binds slipped-CAG DNA intermediates, induces contractions of expanded repeats and reduces mutant HTT protein aggregates in cell and animal models of Huntington’s disease.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates and transition states. I hope my blog about 754-05-2 is helpful to your research. Application In Synthesis of Trimethyl(vinyl)silane.

The synthesis of a novel layered double hydroxide (LDH)-based N-amidinoglycine-functionalized magnetic nanocomposite, gamma-Fe2O3@Cu3Al-LDH-N-amidinoglycine, has been described. The structure of the synthesized nanoparticles was characterized by different physicochemical techniques such as X-ray diffraction (XRD), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), energy dispersive X-ray spectroscopy (EDX), and scanning electron microscopy (SEM), and using a vibrating sample magnetometer (VSM). These newly developed magnetic nanoparticles have been explored as a magnetically separable amphoteric nanocatalyst for the synthesis of new pyrimido[4,5-b][1,8] naphthyridine-7-carbonitrile derivatives in excellent yields via one-pot three-component reaction between aldehydes, 3-cyano-6-hydroxy-4-methyl-pyridin-2(1H)-one, and N,N-dimethyl-6-aminouracil. In the subsequent part of the present research, these synthesized pyrimido[4,5-b][1,8]naphthyridines were evaluated for their antioxidant and antifungal activities in vitro by using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and PDA (potato dextrose agar) medium, respectively.

In a article, author is Nakamori, Masayuki, introduce new discover of the category.

Recent technological advancements in genetic analysis have allowed for the consecutive discovery and elucidation of repeat expansion disorders: diseases caused by the abnormal expansion of repeat sequences in the genome. Many of these repeat expansion disorders are neurodegenerative movement disorders. Radical cures for these disorders have yet to be established. Although conventional treatments for repeat expansion disorders have mainly targeted the abnormal mRNA and proteins encoded by the affected genes, therapeutic approaches targeting repeat DNA, the root cause of repeat disorders, is also being explored in current research. In particular, a small molecule has been found that binds to abnormally expanded CAG repeats, the cause of Huntington’s disease, and shortens them. Such small molecules targeting nucleic acids are expected to be developed into groundbreaking therapeutic drugs capable of ameliorating the symptoms of repeat expansion disorders and preventing their onset.

n-Alkyllithiums were added to alpha,alpha’-disubstituted-1,8-naphthyridines in non-polar solvents Such as Et2O-hexane mixtures. In polar solvents such as THF, alkyllithium acts as a base rather than a nucleophile. Regioselective addition was achieved for substrates capable of five-membered cyclic chelation of the (alkyl)lithium reagent. Substrates with a TBS-protected alcohol as the co-chelating moiety afforded the best combination of yield and regioselectivity. This methodology was Successfully employed in the preparation of two 6-amino-3-pyridinol analogs of pentamethyl-chromanol (PMC), an alpha-tocopherol derivative with its isoprenoid side chain truncated to a methyl group.

A dirhodium complex bearing a newly-designed silyl-1,8-naphthyridine ligand (napySi), [Rh(kappa Si-2,N-napySi)(H)(mu-Cl)](2) (1), was synthesized. Reaction of complex 1 with excess BH3 center dot SMe2 afforded a mononuclear borane adduct Rh[kappa Si-4,N,H,H-napySi(BH3)](H)Cl (2), revealing that rhodium and the uncoordinated naphthyridine nitrogen cooperatively captured BH3 and weakened its two B-H bonds. Complex 2 contains a Rh(mu-H)(2)B core composed of two Rh-H-B-3-center 2-electron (3c-2e) bonds where one Rh-H interaction is considerably weakened by strong trans-influence of the silyl ligand moiety.

Further reaction of 1 with rhenium carbonyls yielded ortho-metallation dinuclear rhenium complex 2. Both complexes were characterized by spectroscopic analyses and single-crystal X-ray determination. Complex 1 also reacted with [PdMeCl(COD)] and [Ir(COD)Cl]2 by means of ortho-metallation to yield the corresponding heterodinuclear species. Complex 2 appears to be an excellent precatalyst to promote the insertion of terminal alkynes into acetoacetates, which subsequently undergo cyclization to form 2-pyranones.
