F.; Desmond-Smith, Nicholas; Bianchi, Loria; Della Corte, Laura published an article in 1996, the title of the article was Role of taurine in thermoregulation and motor control: behavioral and cellular studies.HPLC of Formula: 636-73-7 And the article contains the following content:

Taurine may have a role in the striatonigral system of the rat. Considering that, whether a neurotransmitter or a neuromodulator, taurine must be recognized before initiating its action, in the present contribution a structure-activity relationship study is presented which gives some information on the nature of a possible recognition site in the rabbit brain, helping to explain the role of endogenous taurine in the central mechanisms of thermoregulation. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).HPLC of Formula: 636-73-7

On May 31, 1999, Decristoforo, Clemens; Mather, Stephen J. published an article.Product Details of 636-73-7 The title of the article was 99M-technetium-labelled peptide-HYNIC conjugates: Effects of lipophilicity and stability on biodistribution. And the article contained the following:

The aim of this study was to explore the effects of lipophilicity and stability on the biodistribution of 99mTc labeled peptides through the use of different co-ligands. 6-Hydrazinopyridine-3-carboxylic acid (HYNIC) was coupled to the somatostatin analog RC160 and radiolabeled using a range of ethylenediaminediacetic acid (EDDA) and EDTA derivatives as well as tricine and pyridine/tricine as co-ligands. After labeling with technetium-99m, chromatog., stability, protein-binding, and rat biodistribution studies were performed. For most co-ligands, biodistribution correlated well with in vitro properties. Lipophilic substitution on EDDA resulted in higher protein binding, increased liver uptake, and intestinal excretion. Stabilization of tricine with pyridines reduced blood levels and lowered liver uptake. EDTA derivatives showed high instability in vitro and in vivo. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Product Details of 636-73-7

On October 31, 2011, Raghu, M. S.; Basavaiah, K. published an article.Recommanded Product: N,N-Dimethyl-3-phenyl-3-(pyridin-2-yl)propan-1-amine maleate The title of the article was Two charge-transfer complexation reactions for spectrophotometric determination of pheniramine maleate using π-acceptors. And the article contained the following:

This study presents two simple, selective and rapid spectrophotometric methods for determination of pheniramine maleate (PAM) in pure form and in its formulations. Both methods are based on the formation of charge-transfer (CT) reaction of PAM with p-chloranilic acid (CAA) or 2,3-dichloro-5,6-dicyanoquinone (DDQ) in 1,4-dioxan-acetonitrile medium. CT complexes were quantified at 530 and 590 nm for CAA and DDQ methods, resp. Beer’s law is obeyed (concentrate ranges, 12.5-200 μg/mL-1 for CAA and 5-80 μg/mL-1 for DDQ method), with correlation coefficients (r) of 0.9999 and 0.9991. Apparent molar absorptivities are calculated to be 1.27 × 103 and 3.06 × 103 l/mol-1/cm-1, resp. and corresponding Sandell sensitivities are 0.281 and 0.112 μg/cm-2. Developed methods were successfully applied for determination of PAM in tablets and injections. The experimental process involved the reaction of N,N-Dimethyl-3-phenyl-3-(pyridin-2-yl)propan-1-amine maleate(cas: 132-20-7).Recommanded Product: N,N-Dimethyl-3-phenyl-3-(pyridin-2-yl)propan-1-amine maleate

Raghu, M. S.; Basavaiah, K. published an article in 2012, the title of the article was Rapid and Sensitive Extraction-Free Spectrophotometric Methods for the Determination of Pheniramine Maleate Using Three Sulphonthalein Dyes.Formula: C20H24N2O4 And the article contains the following content:

Three extraction-free spectrophotometric methods which are simple, selective and sensitive are described for the quantitation of pheniramine maleate (PAM), an antiallergic drug, in pure form and in its formulations. The methods are based on formation of yellow colored ion-pair complexes between PAM and 3 sulfonthalein dyes viz., bromothymol blue (method A), and bromocresol purple (method B) in dichloromethane, and bromocresol green (method C) in chloroform medium. The exptl. variables such as reagent concentration, solvent medium and reaction time were carefully optimized to achieve the highest sensitivity. Beer’s law is obeyed over the concentration ranges 1.0-16.0 for method A and method B, and 0.6-12 μg ml-1 PAM for method C with correlation coefficient of 0.999 for method A and method B, and 0.997 for method C. The molar absorptivity values are calculated to be 2.3 × 104, 2.5 × 104 and 3.0 × 104 l mol-1 cm-1 for the methods in the same order. The composition of the ion-pairs was found to be 1:1 by Job’s method of continuous variations and the conditional stability constant (K f) of the complexes were calculated The proposed methods were applied successfully to the determination of PAM in tablets and injection with good accuracy and precision and without interferences from common additives. The results obtained by the proposed methods were compared favorably with those of the reference method.

On May 24, 1991, Karaman, Rafik; Bruice, Thomas C. published an article.Computed Properties of 636-73-7 The title of the article was Synthesis and characterization of the first water-soluble closely interspaced cofacial porphyrin dimer. And the article contained the following:

The only documented example of a quadruply-bridged, closely-interspaced cofacial porphyrin dimer was synthesized by Kagan (1977). The target of this communication is the synthesis and characterization of the first water soluble quadruply-bridged, closely-interspaced cofacial porphyrin I (R = R1). Reaction of meso-tetrakis(3-bromomethylphenyl)porphyrin with m-pyridinesulfonamide provides the closely-interspaced cofacial porphyrin dimer I (R = R2) which on quaternization with MeI provides the water soluble I (R = R1). Reactions of I with Zn(OAc)2 provided the corresponding bis-zinc complexes I. Porphyrins I and their bis-zinc complexes, exist in a closed down conformation with closely approaching porphyrin planes or in an open conformation. It was established, on the basis of 1H-NMR UV/vis, and emission spectrophotometries, and I (R = R2) exists in a closed down conformation in DMSO or acetone and a more open conformation is CHCl3. With zinc complexes of I (or protonated I) the conformation is open regardless of the solvent. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Computed Properties of 636-73-7

In the reaction of 4-methoxypyridine derivatives with alkyl iodides in the presence or absence of solvent, not only the pyridinium ions but also the related 1-methylpyridones are produced. The presence of solvent favors the formation of the 1-methylpyridone. Electron withdrawing groups on the pyridine ring also favor this conversion. A possible mechanism is presented.

On August 31, 2011, Chisholm, Danielle M.; McDonald, Robert; McIndoe, J. Scott published an article.Recommanded Product: [2,2′-Bipyridine]-3,3′-diamine The title of the article was 3,3′-N,N’-Bis(amino)-2,2′-bipyridine – An unusually methylation-resistant amine. And the article contained the following:

Methylation of aromatic amino groups is usually straightforward, but the formation of two intramol. hydrogen bonds in 3,3′-N,N’-bis(amino)-2,2′-bipyridine and (or) the potential for ring methylation prevents the clean tetramethylation of this mol. Numerous attempts to make 3,3′-N,N’-bis(dimethylamino)-2,2′-bipyridine produced only complex mixtures of variously methylated products, and the only isolated mol. was 3,3′-N,N’-bis(methylamino)-2,2′-bipyridine, for which an X-ray crystal structure was obtained.
