Herpes Simplex Virus (HSV) infections are among the most common human diseases. In this work, we assess the structural features and electronic properties of a series of ten 1-hydroxyacridone derivatives (1a-j) recently described as a new class of non-nucleoside inhibitors of Herpes Simplex Virus-1 (HSV-1). Based on these molecules, we applied rigid analogue and isosteric replacement approaches to design and synthesize nine new 3H-benzo[b]pyrazolo[3,4-h]-1,6-naphthyridine derivatives (2a-i). The biological and computational results of these new molecules were compared with 1-hydroxyacridones. An inhibitory profile was observed in 10-Cl substituted 3H-benzo[b]pyrazolo[3,4-h]-1,6-naphthyridine derivative (2f), which presents the same substituent at the analogous position of 1-hydroxyacridone derivative (1b). The structure-activity relationship (SAR) studies pointed out the 10-position next to nitrogen atom as important for the anti-HSV-1 profile in the pyrazolo-naphthyridine derivatives tested, which reinforced the promising profile for further experimental investigation. The most potent acridone and pyrazolo-naphthridine derivatives were also submitted to an in silico ADMET screening in order to determine their overall drug-score, which confirmed their potential antiviral profile.

Discrimination of base mismatches from normal Watson-Crick base pairs in duplex DNA constitutes a key approach to the detection of single nucleotide polymorphisms ( SNPs). We have developed a sensor for a surface plasmon resonance (SPR) assay system to detect G-G, A-A, and C-C mismatch duplexes by employing a surface upon which mismatch-binding ligands (MBLs) are immobilized. We synthesized a new MBL consisting of 2,7-diamino-1,8-naphthyridine (damND) and immobilized it onto a CM5 sensor chip to carry out the SPR assay of DNA duplexes containing a single-base mismatch. The SPR sensor with damND revealed strong responses to all C-C mismatches, and sequence-dependent C-T and T-T mismatches. Compared to ND- and naphthyridine-azaquinolone hybrid (NA)-immobilized sensor surfaces, with affinity to mismatches composed of purine nucleotide bases, the damND-immobilized surface was useful for the detection of the mismatches composed of pyrimidine nucleotide bases.

New 3-aryl-pyrido[2,1-b][1,3] benzothiazole derivatives 2a-e were synthesized in excellent yields via the reaction of benzothiazoleacetonitrile (1) with different aromatic aldehydes. The treatment of 2-(benzo[d] thiazol-2-yl)-3-(pyridin-4-yl) acrylonitrile (6) with malononitrile afforded 1-amino-3-(pyridin-4-yl)-3H-pyrido[2,1-b][1,3] benzothiazole-2,4-dicarbonitrile (7), which was allowed to react with a variety of reagents to provide pyrimido[5′, 4′: 5,6] pyrido[2,1-b][1,3] benzothiazole 8, 9 and [1,3] benzothiazolo[3,2-a][1,8] naphthyridine 10, 15 derivatives. All synthesized products were confirmed by elemental analysis, IR, H-1-NMR, C-13-NMR, and mass spectral data.

In an article, author is Millet, Agustin, once mentioned the application of 620-92-8, Name is 4,4′-Methylenediphenol, molecular formula is C13H12O2, molecular weight is 200.23, category is naphthyridine.

The cis- and trans-dirhodium(II,II) complexes cis-[Rh-2(mu-DTolF)(2)(mu-np)(MeCN)(4)][BF4](2) (1; DTolF = N,N’-di-p-tolylformamidinate and np = 1,8-naphthyridine), cis- and trans-[Rh-2(mu-DTolF)(2)(mu-qxnp)(MeCN)(3)][BF4](2)[2 and 3, respectively, where qxnp = 2-(1,8-naphthyridin-2-yl)quinoxaline], and trans-[Rh-2(mu-DTolF)(2)(mu-qxnp)(2)[BF4](2 )(4) were synthesized and characterized. A new synthetic methodology was developed that consists of the sequential addition of Jr-accepting axially blocking ligands to favor formation of the first example of a bis-substituted formamidinate-bearing trans product. Isolation of the intermediates 2 and 3 provides insight into the mechanistic requirements for obtaining 4 and the cis analogue, cis-[Rh-2(mu-DTolF)(2)(mu-qxnp)(2)[BF4](2 ) (5). Density functional theory calculations provide support for the synthetic mechanism and proposed intermediates. The metal/ligand-to-ligand charge-transfer (ML-LCT) absorption maximum of the trans complex 4 at 832 nm is red-shifted by 1173 cm(-1) and exhibits shorter lifetimes of the (ML)-M-1-LCT and (ML)-M-3-LCT excited states, 3 ps and 0.40 ns, respectively, compared to those of the cis analogue 5. The shorter excited-state lifetimes of 4 are attributed to the longer Rh-Rh bond of 2.4942(8) angstrom relative to that in 5, 2.4498(2) angstrom. A longer metal-metal bond reflects a decreased overlap of the Rh atoms, which leads to more accessible metalcentered excited states for radiationless deactivation. The (ML)-M-3-LCT excited states of 4 and 5 undergo reversible bimolecular charge transfer with the electron donor p-phenylenediamine when irradiated with low-energy light. These results indicate that trans isomers are a source of unexplored tunability for potential p-type semiconductor applications and, given their distinct geometric arrangement, constitute useful building blocks for supramolecular architectures with potentially interesting photophysical properties.

Tailor-made naphthyridines: Self-assembling multiple hydrogen-bonded supramolecular architectures from dimer to helix

Stepwise changes of functional oxo and amino groups in 1,8-naphthyridines to modify the supramolecular architecture have been carried out. The first example of a naphthyridine helix has been found and its structure established by X-ray crystallography. The design is based on hydroxy and amido tautomeric naphthyridines which crystallize in dimers or catemers, one of them attaining helicity. The most stable tautomer present in all the compounds discussed in this paper, as well as the formation of hydrogen-bonded dimers or catemers, was established by X-ray crystallography and rationalized with theoretical calculations.
