A computational study on 4-amino-3-hydroxynaphthalene-1-sulfonic acid (AHNSA) has been carried out to investigate formation of poly-(AHNSA), and to obtain binding structures and energies of AHNSA-Ephedrine and AHNSA-Caffeine complexes. For this purpose, the DFT/B3LYP/6-31G(D) and DFT/B3LYP/6-31+G(D) level of theories were utilized. These were investigated from anal. of their at. charge distributions, total spin d., frontier MOs, electrostatic potential maps and calculations of binding energies. Results from anal. suggest that homo-polymerization of AHNSA should involve the MOs arising between radical cations formed from the neutral monomer. The resulting data illustrated that the method was likely to be useful for homopolymerization of AHNSA. Calculated binding energies of AHNSA-Caffeine and AHNSA-Ephedrine complexes were -8.77 kcal mol^-1 and -8.36 kcal mol^-1, resp., which indicated that both complexes could be formed.

Slovesnova, Nataliya V. published the artcileSynthesis of new water-soluble polyarene-substituted naphtho[1,2-d]oxazole-based fluorophores as fluorescent dyes and biological photosensitizers, Product Details of C10H9NO4S, the publication is Dyes and Pigments (2022), 110410, database is CAplus.

Two new water-soluble PAH-substituted (PAH – polyaromatic hydrocarbon) naphtho[1,2-d] [1,3]oxazole dyes 1-2 were synthesized and investigated for intramol. charge transfer (ICT) behavior, aggregation, and ability to fluorescent staining and photosensitization on living cancer cells of HeLa and Vero cultures. To make clear this behavior a detailed anal. of the relationship between the structure and photophys. properties 1-2 were carried out based on exptl. and computation data. As a result of the staining experiment, there was a diffuse distribution in the cytoplasm of 2-(9-anthracenyl)-containing naphthoxazole 1 as a hydrophilic fluorophore. Whereas 2-(1-pyrenyl)-derivative 2 showed accumulation in the endoplasmic reticulum, as well as addnl. distribution in lipid bilayers. Photodynamic activity of type II was confirmed for the cationic exogenous photosensitizer 2: the IC₅₀ value in the case of HeLa cell culture was 0.50μM. The radical mechanism of photodynamic activity was determined by the EPR method.

Schiff base derived from the condensation reaction of analar grade 1-amino-2-naphthol 4-sulfonic acid with cinnamaldehyde was prepared under microwave condition. The Schiff base was analyzed by IR spectroscopy. This Schiff base as a corrosion inhibitor of AZ31 magnesium alloy in 0.05 mol/L HCl solution was studied. The inhibition effect of the Schiff base compound (4Z)-4-(3-Ph allylidene amino)-3-hydroxy naphthalene-1-sulfonic acid (AC) on AZ31 magnesium alloy corrosion was studied using mass loss, potentiodynamic polarization technique, electrochem. impedance spectroscopy methods. The potentiodynamic polarization curve shows that Schiff base AC inhibits both anodic and cathodic reactions at all concentration, which indicates it is a mixed type inhibitor. EIS results indicate that as the additive concentration is increased, the polarization resistance increases whereas double-layer capacitance decreases. The adsorption of AC on the AZ31 magnesium alloy surface in 0.05 mol/L HCl obeys the Langmuir adsorption isotherm.

A voltammetric sensor for the simple and rapid determination of dopamine (DA) has been developed using a glassy carbon electrode modified with cobalt nano/poly (4-amino-3-hyroxy-1-naphthalenesulfonic acid) composite. On square wave voltammetric mode, the modified electrode was found to efficiently catalyze the electrochem. oxidation of DA in 0.1 M PBS (pH 7). Response of DA increased linearly with its concentration in the range 5 脳 10^-5 M to 5 脳 10^-7 M with a limit of detection (LOD) 1.75 脳 10^-8 M. Reliability of the developed sensor in real sample anal. was ascertained successfully by determining DA in artificial blood serum, urine and cerebrospinal fluid (CSF).

A rapid, simple and reliable electrochem. sensor for the simultaneous determination of xanthine (XA) and hypoxanthine (HX) based on poly(4-amino-3-hydroxy naphthalene-1-sulfonic acid) [p(AHNSA)] modified glassy carbon electrode (GCE) is reported here. The proposed sensor permit well resolved and well separated peaks for XA and HX in 0.1 M NaOH at comparably lowest potential by square wave voltammetric (SWV) technique. The exptl. parameters required for the electroxidn. of both XA and HX are optimized. For simultaneous determination, the oxidation peak current showed a linear variation in the concentration range 4.0 x 10-4-3.0 x 10-6 M and 2.0 x 10-4-6.0 x 10-6 M with detection limits 7.1 x 10-7 M and 1.5 x 10-6 M for XA for HX, resp. The mechanistic aspects were studied by linear sweep voltammetry (LSV) and the electrode processes were found to be diffusion controlled. The developed sensor was found to have promising application in some real samples like tea and coffee and in physiol. samples with good selectivity and sensitivity.
