Synthesis and biological studies of a new series of 5- heteroarylcarbamoylaminopyrazolo[4,3-e]1,2,4-triazolo[1,5-c]pyrimidines as human A3 adenosine receptor antagonists. Influence of the heteroaryl substituent on binding affinity and molecular modeling investigations

Some pyrazolotriazolopyrimidines bearing different heteroarylcarbamoylamino moieties at the N5-position are described. We previously reported the synthesis of a water soluble compound with high potency and selectivity versus the human A3 adenosine receptor as antagonist, and herein we present an enlarged series of compounds related to the previously mentioned one. These compounds showed A3 adenosine receptor affinity in the nanomolar range and different levels of selectivity evaluated in radioligand binding assays at human A1, A2A, A2B, and A3 adenosine receptors. In particular, the effect of the heteroaryl substituents at the N5 position has been analyzed. This study allows us to recognize that the presence of a pyridinium moiety in this position not only increases water solubility but also improves or retains potency and selectivity at the human A3 adenosine receptors. In contrast, replacement of pyridine with different heterocycles produces loss of affinity and selectivity at the human A3 adenosine receptors. A molecular modeling study has been carried out with the aim to explain these various binding profiles.

Base-free nickel-catalysed decarbonylative Suzuki?Miyaura coupling of acid fluorides

The Suzuki?Miyaura cross-coupling of organoboron nucleophiles with aryl halide electrophiles is one of the most widely used carbon?carbon bond-forming reactions in organic and medicinal chemistry1,2. A key challenge associated with these transformations is that they generally require the addition of an exogenous base, the role of which is to enable transmetallation between the organoboron nucleophile and the metal catalyst3. This requirement limits the substrate scope of the reaction because the added base promotes competitive decomposition of many organoboron substrates3?5. As such, considerable research has focused on strategies for mitigating base-mediated side reactions6?12. Previous efforts have primarily focused either on designing strategically masked organoboron reagents (to slow base-mediated decomposition)6?8 or on developing highly active palladium precatalysts (to accelerate cross-coupling relative to base-mediated decomposition pathways)10?12. An attractive alternative approach involves identifying combinations of catalyst and electrophile that enable Suzuki?Miyaura-type reactions to proceed without an exogenous base12?14. Here we use this approach to develop a nickel-catalysed coupling of aryl boronic acids with acid fluorides15?17, which are formed in situ from readily available carboxylic acids18?22. This combination of catalyst and electrophile enables a mechanistic manifold in which a ?transmetallation-active? aryl nickel fluoride intermediate is generated directly in the catalytic cycle13,16. As such, this transformation does not require an exogenous base and is applicable to a wide range of base-sensitive boronic acids and biologically active carboxylic acids.

Recent advances in the discovery of D-amino acid oxidase inhibitors and their therapeutic utility in schizophrenia

D-Amino acid oxidase (DAAO) catalyzes the oxidative metabolism of D-amino acids including D-serine, a full agonist at the allosteric glycine binding site of the NMDA receptor. D-serine was reported to improve negative and cognitive symptoms of schizophrenia, symptoms poorly addressed by the standard D2 antagonist therapies. Therefore, inhibition of DAAO has gained substantial interest as an effective way to increase D-serine levels in the brain. During the last several years, a growing number of structurally diverse DAAO inhibitors have been identified with significantly higher inhibitory potency compared to the conventional DAAO inhibitors. Some of these new generation of DAAO inhibitors are being evaluated for their ability to enhance D-serine levels in rodents and efficacy in animal models of schizophrenia. This article highlights the progress that has been made toward the discovery of DAAO inhibitors and recent efforts to exploit their therapeutic utility in schizophrenia.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 496-41-3, you can also check out more blogs about496-41-3

Oxidative Cleavage of beta -Keto Sulfones via Nitrous Acid

The reaction of nitrous acid with 1-aryl-2-(arylsulfonyl)ethanones 3a-e afforded the unexpected arenecarboxylic acids 12a-e, formic acid 14, and benzene/4-toluenesulfinic acid 15a, b through oxidative cleavage reaction. 4-Chlorobenzoic acid (12a), [1,1?-biphenyl]-4-carboxylic acid (12b), 2-naphthoic acid (12c), 2-thiophenecarboxylic acid (12d), and 2-benzofurancarboxylic acid (12e) were isolated in 72%, 62%, 55%, 58%, and 62% yields, respectively. The reported mechanistic pathways proposed the production of 1-aryl-2-(phenyl/tolylsulfonyl)ethane-1,2-dione 7 instead of arenecarboxylic acids 12. A mechanistic pathway to explain the reaction of nitrous acid with 1-aryl-2-(arylsulfonyl)ethanones 3a-e was suggested. In this pathway, the intermediate 1,2-oxazete 10 lost benzene/4-toluenesulfinic acid 15 to produce 1,2-oxazet-3-one 11. Ring cleavage of the latter intermediate afforded the arenecarboxylic acids 12.

Antioxidant properties of 3-hydroxycoumarin derivatives

A series of hydroxylated 3-hydroxycoumarins was synthesised and evaluated for their antioxidant properties. The compounds substituted on the C-7 position were almost as antioxidant as quercetin or vitamin C. The antioxidant properties were related by an EPR study to their abilities to give stable semiquinonic or polyhydroxylated radicals. A series of hydroxylated 3-hydroxycoumarins was synthesised by the reaction of 3-aryl-2-hydroxypropenoic derivatives with boron tribromide. They were evaluated for their ability to scavenge the 2,2-diphenyl-1-picrylhydrazyl radical, the superoxide anion radical, the hydroxyl radical and the peroxynitrite anion and to inhibit copper-induced human LDL peroxidation. The physicochemical results were in accordance to establish the compounds hydroxylated on C-6 and C-7 positions as the most active of the series with antioxidant potencies comparable to those of quercetin and vitamin C. These compounds form o- and p-quinonoid derivatives upon radical scavenging and may serve as new lead compounds for pharmacological investigations.

Orthogonal sp3 C1-H and N-H Bond Functionalization of 1,2,3,4-Tetrahydroisoquinolines via the Ugi Four-Component Reaction

A new protocol for orthogonal sp3 C1-H and N-H bond functionalization of 1,2,3,4-tetrahydroisoquinolines has been established via the Ugi four-component reaction with aldehydes, isonitriles, and carboxylic acids. It was revealed that only the N-H bond could be functionalized when the reaction was performed in acetonitrile at room temperature; however, when the reaction was carried out in toluene at 80 C, redox-neutral sp3 C1-H bond functionalization of 1,2,3,4-tetrahydroisoquinolines was achieved. Differing from the common role of carboxylic acid as a promoter in redox-neutral amine alpha-functionalization, the carboxylic acid employed herein is also a reactant. The orthogonal process is compatible with various substrates and provides an appealing access to a library of structurally diverse 1,2,3,4-tetrahydroisoquinolines.
