In a document, author is Mouradzadegun, Arash, introduce the new discover, SDS of cas: 696-63-9.

N-propyl sulfamic acid supported nano-catalyst on the basis of calix[4]resorcinarene was prepared via the efficient and facile reaction of amine functionalized polycalix[4]resorcinarene with chlorosulfonic acid. The achieved catalytic system was characterized using some spectroscopic techniques such as Fourier transform Infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), and CHNS elemental analysis. This newly developed acidic catalyst was employed efficiently in a one-pot three-component condensation reaction of aromatic aldehydes, dimedone and phthalhydrazide for the synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives through an easy and eco-friendly methodology. The catalyst was easily separated from the reaction mixture by simple filtration and the desired products were achieved in good to excellent yields in short reaction times.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 696-63-9 help many people in the next few years. SDS of cas: 696-63-9.

Four phthalazine derivatives have been prepared from substituted 2-bromobenzaldehyde acetals by a sequence involving: (1) lithiation and formylation; (2) deprotection; and (3) condensative cyclization with hydrazine. Two additional phthalazines were prepared by a similar sequence following direct lithiation of benzaldehyde acetals substituted by anion-stabilizing groups at C3. These syntheses can be conveniently carried out to give phthalazines in overall yields of 40-70%.

In a article, author is Uehara, Shotaro, introduce new discover of the category.

Common marmosets (Callithrix jacchus), New World monkeys, are a promising primate model for preclinical drug metabolism studies because of the similarities of cytochrome P450 (P450) enzyme function to those of humans. Despite an increasing number of drug candidates catalyzed by non-P450 enzymes, drug metabolizing enzymes other than P450s have been hardly identified or characterized in marmosets. In this study, we identified aldehyde oxidase (AOX) 1 gene by marmoset genome analysis. AOX1 cDNA was cloned from marmoset livers by reverse transcription-polymerase chain reaction. Deduced amino acid sequences of AOX1 cDNA showed high sequence identities (92-93%) with primate AOX1s. Phylogenetic analysis showed that marmoset AOX1 was closely clustered with primate AOX1s, unlike nonprimate animal model AOX1s of pig, rabbit, rat, and mouse used in drug metabolism. The tissue expression analyses by real-time reverse-transcription polymerase chain reaction and immunoblotting showed that marmoset AOX1 mRNA and protein were abundantly expressed in livers, similar to cynomolgus monkeys and humans. Marmoset AOX1 heterologously expressed in Escherichia coli catalyzed the oxidation of carbazeran and phthalazine, typical AOX1 substrates, similar to cynomolgus monkey and human AOX1s. Human and marmoset AOX1 effectively catalyzed phthalazine oxidation when assessed with Michaelis-Menten kinetics, but cynomolgus monkey AOX1 catalyzed this reaction with cooperative kinetics with high capacity. These results indicated that tissue distribution and enzymatic function of AOX1 enzyme is similar between marmosets and humans, suggesting that marmosets are a suitable primate model for AOXdependent drug metabolism in preclinical studies.

Nano-organocatalyzed one-pot four-component reactions for the synthesis of phthalazine-trione/dione derivatives have been devised for the first time from easily accessible starting materials under solvent-free conditions. This methodology showed very good substrate scope and high degree of tolerance for a variety of aldehydes (including aliphatic and heteroaromatic aldehydes) and active methylene compounds. Moreover, the catalyst can be easily separated from the reaction mixture because of its highly paramagnetic nature, by using an external magnet, and can be reused in five more consecutive runs without much decrease in catalytic activities. Other significant advantages of this method are shorter reaction time, good yield, simple work-up procedure, easy catalyst handling etc.

In a article, author is Awadallah, Fadi M., introduce new discover of the category.

New phthalazine-based vasodilators were synthesized through the chloroacylation of the starting compound 1-hydrazinophthalazine 4 to give the two key intermediates 5 and 7. These intermediates were used to alkylate various cyclic amines to furnish the final compounds 6a-h and 8a-h. Compounds were tested for their vasorelaxant activities against nor-adrenaline-induced spasm on thoracic rat aorta rings and compared to the reference drug, prazosin. Seven compounds showed higher activity than prazosin, especially compound 8d having an IC50 = 0.10 mM. Molecular modeling studies, including fitting of the synthesized compounds to a 3D-pharmacophore and their docking into optimized homology model as alpha(1)-AR antagonists showed high docking score and fit values. Most vasodilation activities of tested compounds are consistent with their molecular modeling results. (C) 2012 Elsevier Masson SAS. All rights reserved.
