Novel benzofuran-based sulphonamides as selective carbonic anhydrases IX and XII inhibitors: synthesis and in vitro biological evaluation

Pursuing on our efforts toward searching for efficient hCA IX and hCA XII inhibitors, herein we report the design and synthesis of new sets of benzofuran-based sulphonamides (4a,b, 5a,b, 9a-c, and 10a-d), featuring the zinc anchoring benzenesulfonamide moiety linked to a benzofuran tail via a hydrazine or hydrazide linker. All the target benzofurans were examined for their inhibitory activities toward isoforms hCA I, II, IX, and XII. The target tumour-associated hCA IX and XII isoforms were efficiently inhibited with K (I)s spanning in ranges 10.0-97.5 and 10.1-71.8 nM, respectively. Interestingly, arylsulfonehydrazones 9 displayed the best selectivity toward hCA IX and XII over hCA I (SIs: 39.4-250.3 and 26.0-149.9, respectively), and over hCA II (SIs: 19.6-57.1 and 13.0-34.2, respectively). Furthermore, the target benzofurans were assessed for their anti-proliferative activity, according to US-NCI protocol, toward a panel of sixty cancer cell lines. Only benzofurans 5b and 10b possessed selective and moderate growth inhibitory activity toward certain cancer cell lines.

Application of 66357-35-5, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 66357-35-5 is helpful to your research.

Microwave-Assisted Regioselective Friedel-Crafts Arylation by BF3 . OEt2: A Facile Synthetic Access to 3-Substituted-3-Propargyl Oxindole Scaffolds

A facile microwave-assisted synthetic strategy for the construction of C-C bondviaregioselective Friedel-Crafts arylation of 3-hydroxy-3-phenylethynyl oxindoles with different electron-rich nucleophiles such as phenols, sulphonamides, anisole, benzofuran, and benzothiophene has been established by employing BF3 . OEt(2)as catalyst. The current protocol attributes mild conditions, cost-effective, transition-metal free synthesis, wide substrate scope and moderate to good yields. Moreover, this method is amenable for the generation of a library of densely substituted 3-(4-hydroxyphenyl)-3-(phenylethynyl) oxindoles and 3-(4-benzenesulphonamide)-3-(phenylethynyl) oxindoles as privileged scaffolds.

Access to Multifunctionalized Benzofurans by Aryl Nickelation of Alkynes: Efficient Synthesis of the Anti-Arrhythmic Drug Amiodarone

An unconventional nickel-catalyzed reaction was developed for the synthesis of multifunctionalized benzofurans from alkyne-tethered phenolic esters. The transformation involves the generation of a nucleophilic vinyl Ni-II species by the regioselective syn-aryl nickelation of an alkyne, which then undergoes an intramolecular cyclization with phenol ester to yield highly functionalized 1,1-disubstituted alkenes with 3-benzofuranyl and (hetero)aryl substituents. The methodology can be used for the late-stage benzofuran incorporation of various drug molecules and natural products, such as 2-propylvaleric acid, gemfibrozil, biotin, and lithocholic acid. Furthermore, this arylative cyclization method was successfully applied for the efficient synthesis of the anti-arrhythmic drug amiodarone.

Bis(benzofuran-enaminone) hybrid possessing piperazine linker: Versatile precursor for microwave assisted synthesis of bis(pyrido[2 ‘,3 ‘:3,4]pyrazolo[1,5-a]pyrimidines)

We reported herein efficient procedures for the synthesis of new piperazine-linked bis(pyrido[2′,3’:3,4]pyrazolo[1,5-a]pyrimidines) using bis(benzofuran-enaminone) hybrid as a key intermediate. For this purpose, bis(enaminone) were reacted with a new series of 3-amino-4-(thiophen-2-yl)-1H-pyrazolo[3,4-b]pyridines in pyridine under microwave irradiation at 120 degrees C for 90 min to afford the target bis(pyrimidines). In a two-steps synthetic route, bis(enaminone) was used to prepare a novel bis(3-amino-1H-pyrazolo[3,4-b]pyridine). Next, the former hybrid was reacted with two equivalents of the appropriate enaminones as well as arylidinemalononitriles in pyridine under microwave irradiation at 120 degrees C for 2 h to afford the target bis(pyrimidines). Furthermore, a mixture of bis(pyrazolopyridine) reacted with two equivalents of 1,3-diketones and beta-ketoesters in glacial acetic acid was microwave irradiated at 130 degrees C for 90 min to give bis(2,4-disubstituted pyrimidines) and bis(2-substituted pyrimidin-4(1H)-ones), respectively. The structures of the new hybrids were confirmed via considering their elemental analyses as well as their spectral data. [GRAPHICS] .

Recent Advances in the Cycloaddition Reactions of 2-Benzylidene-1-benzofuran-3-ones, and Their Sulfur, Nitrogen and Methylene Analogues

Benzothiophene, benzofuran, indole, and indene derivatives are privileged heterocyclic motifs. These are present in a wide range of bioactive natural products and pharmaceutical drugs and are the subject of materials science research. However, the construction of benzothiophene, benzofuran, indole, and indene frameworks have been long-standing challenges to organic chemists. In this review, we classify the derivatives of four structures synthesized from 2-benzylidene-1-benzofuran-3-one and their analogues in terms of their ring size (from three- to ten-membered) and type (fused or spiro), as well as summarizing the developments of this field. Finally, we discuss the ring opening and 1,4-addition reactions.

Biocatalytic Strategy for Highly Diastereo- and Enantioselective Synthesis of 2,3-Dihydrobenzofuran-Based Tricyclic Scaffolds

2,3-Dihydrobenzofurans are key pharmacophores in many natural and synthetic bioactive molecules. A biocatalytic strategy is reported here for the highly diastereo- and enantioselective construction of stereochemically rich 2,3-dihydrobenzofurans in high enantiopurity (>99.9% de and ee), high yields, and on a preparative scale via benzofuran cyclopropanation with engineered myoglobins. Computational and structure-reactivity studies provide insights into the mechanism of this reaction, enabling the elaboration of a stereochemical model that can rationalize the high stereoselectivity of the biocatalyst. This information was leveraged to implement a highly stereoselective route to a drug molecule and a tricyclic scaffold featuring five stereogenic centers via a single-enzyme transformation. This work expands the biocatalytic toolbox for asymmetric C-C bond transformations and should prove useful for further development of metalloprotein catalysts for abiotic carbene transfer reactions.
